READ THIS MANUAL!
Please read all information in this manual
carefully in order to gain maximum
performance, safety and enjoyment from your
Lafree electric bicycle.
Congratulations! You have just pedalled into
the exciting world of electric power assistance
for bicycles. In addition to being a full-featured
bicycle, Lafree has an integrated on-board
electric power assist unit. The power assisted
pedal and Variable Power Control (VPC
Throttle) systems are both easy to use and
understand. However, due to their
sophisticated technology, it is extremely
important that you follow the directions for
their operation carefully and completely.
Failure to do so could cause damage to the
motor, energy set (battery pack/charger unit),
VPC Throttle components, or the entire
bicycle.
Even though Lafree functions as a standard
bicycle, you should still review the chapters on
bicycle operation, especially if you haven’t
ridden/owned a bicycle within the last 10
years. Component performance and
configuration has changed dramatically, and
while they are easy to use and understand,
they may not look quite the same as what you
are familiar with! Taking a few moments now
to understand Lafree’s operating procedures
will help you get the most out of every ride.
Please read chapter 6, “Charging the Energy
Set” before operating Lafree’s electric
powered functions. Lafree’s Energy Set
(Battery Pack/Charger Unit) must be charged
completely before motor (power assisted
pedal, Variable Power Control) can be
operated.

2.3 Position of the Serial
Numbers
Please record Lafree’s bike serial number and
battery serial number for future reference. The
serial number of the bike is stamped into the
left rear “dropout” of the frame. The dropout is
the piece of frame that holds the left-side axle
of the rear wheel (Fig 2E).
WHAT IS LAFREE ?
FIGURE 2E
3
The Lafree power assisted electric bicycle is a
new approach to cycling, bringing together
human power and the power of electronic
technology to create a totally new cycling
experience!
Lafree’s exclusive power assisted pedal
system and Variable Power Control (VPC
Throttle) enhance the enjoyment of riding an
ordinary adult bicycle by giving you an extra
boost for climbing hills or riding into a
headwind-all automatically, efficiently, and
instantly.
Lafree’s advanced on-board torque/speed
sensor automatically adjusts to rider input and
determines how much assistance is needed.
The VPC Throttle feature allows you to
manually override power assisted pedal for
extra and/or prolonged assistance.
PAP: Power-Assisted Pedal
Simply turning the power on activates PowerAssisted Pedalling. Atorque sensor, housed
within the gearbox, “senses” the rider’s input.
The electric motor then responds with
measured power. Pedal input is required for
motor output.
VPC: Variable Power Control
(VPC Throttle)
Variable Power Control allows you to fine-tune
the features already available in the Power-
Assisted mode. You control the amount of power
output simply by twisting the VPC Throttle.
3.1 Frequently Asked
Questions (FAQ’s)
Q: Do I need any special skills or licenses to
ride Lafree?
A: Special permits or licensing may be
required to operate Lafree. Check with your
national regulations. In all instances, it is
essential that you know how to ride a
standard bicycle before attempting to ride
Lafree.
Q: What is the “range” of Lafree’s Energy Set?
A: Your range will vary depending on the road
surface and how much you use the
Variable Power Control (VPC Throttle). The
range of the Energy Set at full VPC Throttle
output on flat terrain with no headwind is
approx. 30-40 km.
Q: How long does it take the Energy Set to
fully charge?
A: Approximately four hours (when battery
has less than 1% remaining energy).
Q: Will the motor assist continue when I put
on the brakes?
A: No. This important safety feature shuts the
motor off any time the brakes are applied.
To resume power assist, simply start
pedalling.
6
Q: How many charges will the Energy Set
accept before needing replacement?
A: Lafree’s lead acid battery can be charged
from 300-400 times before replacement.
Q: What are the advantages of the sealed
lead acid battery set that Lafree has
chosen?
A: The lead acid battery uses “deep cycle”
technology, allowing the chemical reaction
to occur within the battery without the need
for an alternator, such as with a car or
motorcycle. This means that the energy is
recycled through the battery each time it is
charged, making it more efficient and safer
to handle.
Q: Can I ride Lafree without the battery?
A: Although Lafree can be ridden as a
standard bicycle, it is strongly
recommended that you do not ride without
the Energy Set in place. If you DO choose
to ride without the Energy Set, do not place
any items in the energy set compartment
other than the energy set as damage may
occur to the battery leads.
Q: Can I ride my Lafree in the rain or through
puddles?
A: Yes. However, you should not spray water
directly at any of the electrical components,
which include the Energy Set, motor, VPC
Throttle, and energy indicator.
Q: Does an electric bicycle require any special
maintenance?
A: The standard bicycle parts can be serviced
by the owner if the correct tools are used.
However, there is no user serviceable
components in the Energy Set, drive motor,
or VPC Throttle components. We
recommend that you follow the service
schedule and take your Lafree to an
authorised Lafree dealer periodically.
Q: Where can I charge my Lafree?
A: Lafree’s Energy Set can be charged at any
110/240 volt grounded electrical socket.
Q: What happens when the Energy Set
becomes depleted?
A: When the energy level in Lafree’s battery
reaches one percent of maximum capacity,
the battery needs to be re-charged. Simply
plug Lafree’s power cord into any approved
power outlet (see Section 6.1,Charging the
Energy Set).
Q: Will temperature effect the range of
Lafree’s Energy Set?
A: Extremes in heat and cold may effect
maximum energy range (see Section 6).
Q: What is the maximum speed of Lafree?
A: The maximum speed under full VPC
Throttle assist is 25km/h. Once Lafree has
reached or exceeded 25km/h, the motor
will automatically disengage until the speed
falls below 25 km/h.

BIKE SIZING AND SAFETY
4.1 Size
WARNING: A bike that is too big or too
small for the rider can be difficult to
control and can be uncomfortable. If
your bicycle does not fit properly, you
may lose control and fall.
4.1.1 Frame size
Lafree’s sloping “primary frame tube” allows
for greater standover clearance for a wide
variety of riders (clearance between primary
frame tube and top of inseam while straddling
the bike just in front of the saddle). Your
dealer will have made sure you had the
correct standover clearance, based on
physical examination. If someone else
selected a Lafree for you, as a gift, for
example, it is important to have the correct
standover clearance before attempting to ride
it (Fig. 4A). If you cannot stand flat-footed with
feet at shoulder width without coming into
contact with the primary frame tube, we
strongly suggest that you do not attempt to
ride Lafree.
which you’ll be riding, and with feet shoulder
(pedal) width apart. If the top of your inseam
(crotch) touches the frame, the bike is too big
for you.
4.1.2 Saddle Position
Saddle height and position are extremely
important factors in determining your comfort
and performance. Due to Lafree’s unique
hinged saddle, fore/aft saddle position is fixed.
However, the most important aspect of saddle
position - saddle height - can and should be
adjusted for maximum comfort and pedalling
efficiency.
4.1.2.1 Height Adjustment
Put your heel on the pedal at its lowest
position. Your leg should be stretched with a
slight bend in the knee. Use this as a rule of
thumb. If you do not feel comfortable, slight
adjustments may be necessary.
FIGURE 4B
FIGURE 4A
To check for safe standover height, straddle
the bike while wearing the kind of shoes in
To adjust the saddle height: Loosen the seat
binder quick-release cam lever (Fig. 4B; see
also Section 7.8 on Seat Post Quick-Releases) and move the seat post up or down as
required. Re-tighten the seat binder, securing
it so that the post does not twist. Check the
adjustment as described above. Under no
circumstances should the seat post protrude
from the frame beyond its “Minimum Insertion”
or “Maximum Extension” mark (Fig. 4C).
8
FIGURE 4C
WARNING: If the seat post protrudes
from the frame beyond the Minimum
Insertion or Maximum Extension mark
(see Fig. 4C) the seat post may break,
which could cause you to lose control
and fall. Riding Lafree with the seat
post protruding from the frame beyond
the Minimum Insertion or Maximum
Extension mark can also damage the
frame.
Handlebar position can be adjusted as follows
4.1.3.2 Handlebar stem height
There is no general rule for the height of the
handle bar. For a more sportive riding
position, choose a lower position. For a more
recreational riding position choose a higher
position. To adjust the handlebar height:
loosen the stem binder bolt (Fig 4D) three or
four turns. Tap the bolt carefully down, using a
plastic or wooden hammer. Set the handlebar
stem at the correct height and perpendicular
to the front wheel. Fasten the bolt to the
correct torque.
FIGURE 4D
WARNING: After any saddle
adjustment, be sure to tighten the
saddle adjusting mechanism properly
before riding. A loose seat post binder
can cause damage to the seat post, or
can cause you to lose control and fall.
Periodically check to make sure that
the saddle adjusting mechanism is
properly tightened.
4.1.3 Handlebar Height and Angle
4.1.3.1 Handlebar position
The position of the handlebar is important for
comfortable cycling. When adjusting handle
bar position, refer to torque setting table at
section 8.2.
WARNING: The stem’s Minimum
Insertion Mark must not be visible
above the top of the headset (see Fig.
4D). If the stem is extended beyond the
Minimum Insertion Mark the stem may
damage the fork’s steerer tube or
break, which could cause you to lose
control and fall.
4.1.3.3 Handle bar angle
By tilting the handle bar you can direct the
grips more upward or downward. This is a
matter of personal taste. Loosen the bolt at
the front side of the handle bar stem. Tilt the
handle bar to the required position. Fasten the
bolt to the correct torque. Check and if
required adjust the position of the brake
levers.
4.1.3.4 Handle bar stem angle
Some models are equipped with an adjustable
handle bar stem. This allows you to adjust the
angle of the handle bar stem extension.
Loosen the inclination bolt and set the
extension to the required inclination. Fasten
the bolt to the correct torque. Check and if
needed adjust the position of the brake levers.
9
4.2 Safety Equipment
WARNING: Many countries require
specific safety devices. It is your
responsibility to familiarise yourself
with the laws where you ride and to
comply with all applicable regulations,
including properly equipping yourself
and your bike as the law requires.
4.2.1 Reflectors
Reflectors are important safety devices which
are designed as an integral part of Lafree.
The reflectors are designed to pick up and
reflect street lights and car lights in a way that
helps you to be seen and recognised as a
moving bicyclist.
CAUTION: Check reflectors regularly to make
sure that they are clean, straight, unbroken
and securely mounted. Have your dealer
replace damaged reflectors and straighten or
tighten any that are bent or loose.
4.2.2 Lights
If you ride your bike after dusk, your bicycle
must be equipped with lights so that you can
see the road and avoid road hazards; and so
that others can see you. Vehicle laws treat
bicycles like any other vehicle, which means
an illuminated white front, and a red rear light,
not just reflectors, if you are riding after dusk.
A properly fitting lighting system is being
offered as a Lafree optional accessory.
Please ask your dealer.
4.3 Mechanical Safety Checks
Lafree is equipped with several unique safety
features, described in more detail in section 7.
• Speed Actuated Motor Shut-OffAutomatically disengages motor when
Lafree reaches 25 km/h.
• Brake Actuated Motor Shut-OffAutomatically disengages motor when one
or both brakes are applied.
• Automatic Key Lock-Locks Energy Set into
place when ignition is at ON position.
• Self Diagnostic Sequence-Automatically
checks that VPC Throttle, Brake Actuated
Motor Shut-off, and the torque sensor are
functioning.
• Safety switch disables the motor-electric
assist simply by flipping the handlebar
mounted switch to the off position.
Please be sure to familiarise yourself with
these features before operating Lafree. Here
is a simple, sixty-second mechanical safety
check which you should get in the habit of
making every time you’re about to get on
Lafree.
4.3.1 Diagnostic Readout
Lafree is equipped with a five-point diagnostic
check of the electronic features:
• front and rear brake motor cut-off function
• VPC Throttle function
• torque sensor function
• speed sensor function
To initiate diagnostic sequence, turn ignition to
ON position and push Self-Diagnostic button.
4.3.2 Nuts & bolts
Inspect the bike closely from front to rear for
any obvious signs of worn or broken
components. Grasp the handlebar with both
hands and lift the front wheel off the ground
about 5-10 centimetres, then let it drop firmly
on the ground while still holding the
handlebar. If anything sounds, feels or looks
loose, do a quick visual and tactile inspection
of the whole bike. Try to find the source of
noise or any obvious loose components, and
secure them. If you’re not sure, ask someone
with experience to check, or take your Lafree
to your authorised service centre.
4.3.3 Tyres & Wheels
Check proper tyre inflation by placing your
hand directly on top of each individual tyre.
With a straight arm and direct downward
pressure, push on the tyre with downward
body weight and watch the spot where the
tyre is contacting the ground. There should be
very little tyre compression. If your tyres need
10
inflating, use a standard bicycle floor pump. If
you must use a high-volume compressor like
those found at automotive service stations,
add air in small amounts as these
compressors are designed to fill auto tyres
which have much larger volumes than bicycle
tyres. Asurge of pressure could cause the
innertube to explode, which can cause severe
damage to the tyre and serious injury.
Spin each wheel slowly and look for cuts in
the tyre’s tread and sidewall. Replace
damaged tyres before riding the bike.
Spin each wheel and check for brake
clearance and side-to-side wobble of the rim. If
a wheel wobbles side to side or contacts the
brake shoes (front brake only), take the bike to
a qualified dealer to have the wheel aligned.
FIGURE 4F
CAUTION: Wheels must be “true” (aligned)
for the brakes to work effectively. Wheel truing
is a skill which requires special tools and
experience. Do not attempt to true a wheel
unless you have the knowledge and tools
needed to do the job correctly.
4.3.4 Brakes
Lafree offers models with rim brakes (Fig 4E,
4F) and with disc brakes. Visually inspect for
proper cable routing.
Squeeze the brake levers. Brake levers
should engage hoes/rear roller brake at
approximately half way through their arc, or
within about 2,5 centimetres of handlebar grip.
To check proper brake lever travel, encircle
the hand grip with your thumb and forefinger,
then squeeze the brake lever with the
remaining three fingers of each hand. If you
can squeeze the levers so that they touch
your forefinger, you should have a qualified
service centre adjust your brakes.
Make sure that the front brake’s brake shoes
are contacting the rim’s braking surface fully
(Fig. 4H). Also check that the shoes are not
coming into contact with the tyre’s sidewall
whilst applying the brake. Riding the bike with
brake shoes contacting the sidewall can
cause the tyre to be damaged and the
innertube to puncture, which may cause you
to lose control and fall. Do not ride the bike
until the brakes are properly adjusted. See
Section 7.9 for details.
FIGURE 4E
WARNING: Riding with improperly
adjusted brakes or worn brake shoes is
dangerous and can result in serious
injury.
Please see the attached owners manual for
information on disc brakes.
11
FIGURE 4H
4.3.5 Quick-Releases
Check to see that the front and rear wheel
and seat post quick-release levers are
properly adjusted and in the CLOSE position.
See Section 7.7+ 7.8 for details.
WARNING: Riding with an improperly
adjusted wheel quick-release can
cause the wheel to wobble or
disengage from the bicycle, which can
cause damage to the bicycle or serious
injury.
4.3.6 Handlebar and saddle alignment
Are the saddle and handlebar stem correctly
in line with the bike’s top tube and tight
enough so that you can’t twist them out of
alignment?
4.3.7 Handlebar ends
Are the handlebar grips secure and in good
condition? If not, replace them. Are the
handlebar ends plugged? If not, plug them
before you ride.
You are now ready to safely ride your Lafree.
However, we suggest that you take a few
moments to review the following chapters on
riding tips and safety, especially if you have
not ridden a bicycle in a long time.

RIDING SAFELY AND RESPONSIBLY
NOTE: Riding a bicycle involves certain risks,
including damage and injury. By choosing to
ride a bicycle, you assume personal
responsibility for those risks. The people who
sold you the bike, the manufacturer, the
distributor, and people who manage or
maintain the roads and trails you ride on are
not responsible for your actions. Therefore, it
is extremely important that you understandand practice-the rules of safe and responsible
riding, and to use common sense whenever
possible and applicable.
5.1. The Basic
Carry out the Mechanical Safety Check
(Section 4.3) before you attempt to ride
Lafree, In addition, make sure that you always
follow the electronic diagnostic procedure for
Lafree’s power assist features.
5.2. Rules of the Road
1. Learn the local bicycle laws and
regulations. Many countries have special
regulations about licensing of bicycles, riding
on sidewalks, laws regulating bike path and
trail use, and so on. Many countries have
helmet laws, child carrier laws and special
bicycle traffic laws. In most countries, a
bicyclist is required to obey the same traffic
laws as the driver of a car or motorcycle. It is
your responsibility to know and obey the laws.
vehicles sharing the road) is dramatically
reduced, and tyre-to-surface adhesion
(“traction”) is also compromised. This makes it
harder to control speed and easier to lose
control. Whenever wet conditions are present,
reduce speed and apply your brakes earlier
and more gradually than you would under
normal, dry conditions.
5.4 Night Riding
Riding a bicycle at night is much more
dangerous than riding during the day.
WARNING: Riding at dusk, after dark or
at times of poor visibility without a
bicycle lighting system which meets
national laws and without reflectors is
dangerous and can result in accidents.
Before riding at dusk or at night, take the
following steps to make yourself more visible:
• Make sure that your bicycle is equipped
with correctly positioned and securely
mounted reflectors (see Section 4.2.1,
“Reflectors”).
• Make sure that lights and reflectors are not
obstructed by your clothing, accessories, or
anything you may be carrying on the
bicycle.
2. Some Lafree models are equipped with a
front suspension (suspension fork). When
braking, the front suspension compresses and
the front end may drop noticeably. You could
lose control and fall if your riding skills are not
sufficient to negotiate this mechanical function
of the suspension fork. Familiarise yourself
with your suspension by practising braking in
a safe area on flat ground before riding at
higher speeds over varied road surfaces.
5.3 Wet Weather Riding
Under wet conditions, the stopping power of
your brakes (as well as the brakes of other

ELECTRIC ENERGY SET OPERATION
6.1 Charging the Energy Set
(lead acid battery)
Lafree’s portable Energy Set has a selfcontained charger, allowing charging of the
battery virtually anywhere, with or without the
bicycle. Although Lafree can be ridden as a
standard bicycle, it is strongly recommended
that you do not ride without the battery pack in
place.
CAUTION: If riding Lafree without the Energy
Set, do not place any items in the energy set
compartment other than the energy set as
damage may occur to the battery leads.
To charge the battery while Energy Set is
on the bicycle:
Turn ignition to the OFF position.
Park Lafree by placing Lafree’s support stand
in its down and locked position. Charging area
should be level, with good ventilation. Do not
FIGURE 6A
place Lafree or the Energy Set in direct
sunlight, near a heat source (water heater,
furnace, fireplace, etc.), or in contact with
moisture while charging (Fig. 6A).
CAUTION: Do not attempt to charge Lafree’s
Energy Set in temperatures below 0 degrees
Celsius or above 40 degrees Celsius.
WARNING! Do not touch battery while
charging is taking place as battery can
reach temperature of up to 50 degrees
Celsius.
Lift the Energy Set’s charging cord cover,
grasp the plug, and pull to extend cord. If the
cord is difficult to extend or is jammed, do not
pull on plug with force.
Insert the plug into the electric outlet, making
sure that all pins are inserted fully into the
socket. Keep outlet area well ventilated and
free from debris to avoid fire from sparks or
overheating.
When plug is inserted into outlet, the Energy
Set’s red power light (located on right side of
Energy Set below charging cord) will
illuminate, indicating that electricity is flowing
to the battery. This also indicates that energy
level is at or below 80 percent of full charge.
When charging is at or above 81 percent, the
green power light (located next to red power
light), will illuminate. Battery will reach full
capacity after approximately four hours. See
chart in this section for charging times.
Lafree’s Energy Set is equipped with “floating
charge” circuitry. Charging Energy Set after
maximum capacity has been reached will not
harm the battery.
Be aware that the output of a fully charged
battery set may vary approx. 10%. As a
consequence this varies the autonomy.

reached by children or animals.
6.2 Storage & Transportation
6.2.1 Removing, Charging, and
Storing Energy Set
Lafree’s Energy Set can be removed from the
bicycle for easier charging and storage. When
removing, carrying, and storing the Energy
Set, always make sure it is in a level and
upright position (carrying handle on top, facing
upward), and that you never lay the Energy
Set on it’s side or tilt it at an extreme angle.
WARNING: Never lay Energy Set on its
side or tilt it at an extreme angle as
damage to the lead acid battery can
occur, as well as leakage of acid that
can cause injury to body parts or
damage to items and surfaces it may
contact.
To remove Energy Set for storage or charging
away from the bicycle: Place Lafree’s support
stand in its down and locked position. Turn
ignition to OFF position.
• Do not attempt to charge Lafree with a
broken or bent charging plug.
• Do not use any power source other than
110V-240V.
• Do not cover the Energy Set while charging.
• If you notice a strange smell or
vapours/smoke, unplug charging cord
immediately! Take Lafree to your authorised
Lafree dealer for service or replacement.

FIGURE 6C
Release the saddle’s hinge mechanism by
pushing on the lever located under the rear
portion of the saddle (Fig. 6B). Lift up on the
saddle and tilt it forward until the saddle is
vertical (Fig. 6C).
Lift the Energy Set’s retractable sliding
carrying handle and pull up with one hand,
supporting the bottom of the Energy Set with
the other hand once it clears the Energy Set
compartment (Fig. 6D).
Tilt the saddle back to its horizontal and
locked position.
When replacing the Energy Set, make sure
the charger cord/power lights are on the right
side (visible from the riding position) as you
slide the Energy Set into its compartment.
Carefully align the guide plate on the rear of
the Energy Set with the compartment’s
grooves and slowly slide the Energy Set into
place. You will hear a “click” indicating the
base of the Energy Set is contacting the
bottom of the compartment and battery leads.
To store the Energy Set
Before storing, charge the battery to its
maximum capacity. The Energy Set will
discharge automatically and completely after
three months. If you have stored the Energy
Set for longer than two months without
charging, discharge and recharge the battery.
(Please repeat this every two months.)
In case you forgot to discharge your battery
after 2 months, a new recharge will be
necessary. Your dealer will have the
necessary equipment available in order to
carry out this task for you.
WARNING: Leaving the Energy Set in a
discharged state for longer than three
months may effect the long-term life of
the battery. Store Lafree/Energy Set in
the OFF position. However, if left in the
ON position, “automatic sleep” will
engage after 10 minutes.
FIGURE 6D
CAUTION: Store Energy Set in a low, cool,
dry, level, secure area with good ventilation
and away from any heat source.
If storing Lafree with Energy Set in place, turn
ignition to OFF position. Leaving ignition in the
ON position while stored or parked will result
in more rapid energy loss.
6.2.2 Transporting Lafree
When transporting Lafree, it is best to remove
the Energy Set as it is easier to lift and
manoeuvre the bicycle.
CAUTION: Never lay Lafree on its side with
the Energy Set in place as damage to the
lead acid battery can occur, as well as
leakage of acid that can cause injury to body
16
parts or damage to items and surfaces it may
contact. It is also best not to lay Lafree on its
side in any case, as doing so can cause
damage to the control components, motor
housing, pedals, crank arms, and wheels.
6.3 Care & Maintenance
There are no user-serviceable parts in the
Energy Set. If you suspect a problem, take
Lafree and Energy Set to your authorised
Lafree dealer.
• Always pull gently on the charging cord.
Never yank or extend past its full length. To
remove from power outlet, pull on the plug,
not on the cord.
6.4 Radius of action
The radius of action is the distance you can
cycle using the power assistance. The Lafree
radius of action depends on two factors:
• the battery capacity
When cleaning the Energy Set casing, use a
cloth moistened with water only. Do not use
solvents or cleaning solutions of any kind.
Lafree’s lead acid battery must be disposed of
or recycled properly. When the battery will no
longer hold a charge, you must take it to your
authorised Lafree dealer for replacement.
Your authorised Lafree dealer is equipped to
dispose of the battery according to local and
other laws.
CAUTION: Please read the following general
safety tips for care and maintenance of
Lafree’s Energy Set:
• Do not place Energy Set into a fire or near
intense heat source as it can explode and
cause serious injury.
• When cleaning the Energy Set casing, use
a cloth moistened with water only. Do not
use solvents or cleaning solutions of any
kind.
• the cycling circumstances and maintenance
of the bicycle
Under the best possible circumstances, you
can cycle approx. 30-40 km using the power
assistance system. However, the following
factors can influence the radius of action of
your Lafree:
• the temperature
• the wind
• the weight of the rider and loading
• the number of stops and starts
• the terrain (flat, steep hills or slopes,
pavement)
• the quality of tyres and chain
• Do not attempt to open Energy Set’s battery
case or charging unit. There are no userserviceable parts in the Energy Set. If you
suspect a problem, take Lafree and Energy
Set to your authorised Lafree dealer.
• Inspect the Energy Set periodically for
cracks, unusual residue, or other abnormal
appearance. Do not operate Energy Set
with cracks or breaks in the casing.
• Do not attempt to use Energy Set as a
power supply for anything other than Lafree.

HOW THINGS WORK
It is extremely important to the performance,
enjoyment and safety of Lafree and yourself
to understand how many of the features of
Lafree operate. You should not assume that
the way things have worked on previously
owned bicycles operate similarly on Lafree,
even if you’re an experienced bicyclist. Be
sure to read - and to understand - this section
of the owner’s manual. If you have even the
slightest doubt about how any of the
mechanical features of Lafree operate, talk to
your authorised Lafree dealer.
7.1 Variable Power Control
(VPC Throttle)
Lafree’s Variable Power Control (VPC) Throttle
gives you instant access to the motor’s power
for going up hill or into a headwind, or if you
simply don’t want to use any of your own
power! You control the amount of power output
simply by twisting the right VPC Throttle.
Twisting the VPC Throttle in a
counterclockwise direction against the grip’s
spring tension (rearward) applies power from
the electric motor, while releasing the grip in a
clockwise direction (forward) decreases power
from the electric motor (fig. 7A).
The ignition-lockset and safety switch must be
ON. Lafree requires pedal input for motor
output. This means that under any pedal
exertion, Lafree will respond with electrical
assistance. You can control the amount of
power output simply by twisting the VPC
Throttle, which is located on the right side of
the handlebars.
When your speed reaches or exceeds 25 km/h,
Lafree’s motor will automatically disengage and
stop assisting until the speed drops below 25
km/h. You must pedal to enable the motor to
engage VPC Throttle. If you stop pedalling
while VPC Throttle is in the ON (twisted
counterclockwise) position, motor assist will
cease until pedals begin turning again. The
throttle must also be twisted completely
clockwise (no power) then twisted counter
clockwise again for VPC Throttle to engage.
For safety, do not pedal Lafree while the bike
is leaned over in a turn and VPC Throttle
engaged, as the pedal may come in contact
with the ground or other elevated obstacle. It
is best to put the pedals parallel to the ground
at nine and three o’clock, or with the inside
pedal (side the bike is leaning toward) at 12
o’clock and the outside pedal at six o’clock.
WARNING: For safety, do not pedal
Lafree while the bike is leaned over in
a turn and VPC Throttle engaged, as
the pedal may come in contact with the
ground or other obstacles and cause
you to lose control and fall.
CAUTION: Using VPC Throttle exclusively
drains energy more quickly. Use VPC Throttle
sparingly for optimum energy range and
consumption.
FIGURE 7A
7.2 Power Assisted Pedal
Lafree’s power assisted pedal system utilises
a fuzzy logic CPU (central process unit) to
provide constantly monitored power
assistance based on speed and pedal force.
18
To engage power assisted pedal, turn ignition
switch to the on position (please read Section
6.2.1, Charging the Energy Set, before
operating Lafree’s electric functions). Begin
pedalling as with a traditional bicycle. Power
assisted pedal will automatically engage. Be
sure to sit down on the bicycle first with both
hands placed on the handle before riding
away. Other ways of getting on and riding
away could lead to dangerous situations.
• ON-The Energy Set provides power to the
motor and electric features. The Energy Set
is automatically locked into the Energy Set
compartment when ignition is in the ON
position.
• OFF-Lafree’s electronic features will not
function. The Energy Set is locked into the
Energy Set compartment and the key can
be removed. (Use this feature for maximum
security.)
To attain higher or lower speeds, shift the rear
derailleur into the smaller or larger cogs as
described in Section 7.10, “Shifting The Gears.”
When your speed reaches or exceeds 25
km/h, Lafree’s motor will automatically
disengage and stop assisting until the speed
drops below 25 km/h. You must pedal to
enable the motor to engage power assisted
pedal.
7.3 Energy Set Ignition
For the functioning of power assistance and the
diagnostic features, the energy set ignition
must be switched to the ON position. Please
read Section 6, “Charging the Energy Set”
before operating Lafree’s electric powered
functions.
7.3.1 The ignition switch
Your Lafree comes standard with two ignition
keys to operate the ignition switch. Lafree’s
ignition switch has three positions; OPEN, ON
and OFF (fig. 7B):
7.3.2 The safety switch
A remote ON/OFF switch, mounted to the
handlebars, is integrated into the ignition
system. This is called the safety switch. The
safety switch must be turned to the ON
position before electric assistance can be
provided form Lafree’s motor. The switch can
also be used to momentarily turn the Lafree’s
electric assistance off during use.
Start Lafree by turning the key to the ON
position. Following this, turn the safety switch
to the ON position. You should hear an
audible “Beep.” The amount of stored energy
will then appear as 1-5 lights on the energy
indicator located on the top front of the motor
housing. Five lights on the indicator represent
that Lafree’s Energy Set is fully charged.
CAUTION: When leaving Lafree unattended,
turn ignition to OFF position and remove key.
Leaving ignition in the ON position while
parked will result in more rapid energy loss,
and the potential for theft.
• OPEN-Lafree’s electronic features will not
function. The Energy Set can only be
removed when the ignition is in the OPEN
position.
FIGURE 7B
7.4 Self-Diagnostic Check
Lafree is equipped with an on-board five-point
self diagnostic-check of the electronic
features:
• front and rear brake-actuated motor shut-off
function (audible beep sound)
• speed sensor function (audible beep sound)
• VPC Throttle function
• torque sensor function
To initiate self-diagnostic mode, engage
Lafree’s support stand in its down position.
Turn ignition to ON position (there will be a
short beep). The Lafree keys are equipped
19
with a pin to activate the self-diagnostic check.
Push and hold Self-Diagnostic switch, the
small black rubberised button located to the
left of the LED string/energy indicator (Fig.
7C). Release pressure on the button after
hearing a long beep, indicating Self-Diagnostic
check is ready to be performed. To perform
diagnostic check, follow the directions below:
•
Brake Actuated Motor Shut-Off-Pull on each
brake lever individually. If functioning, a
beep will occur each time the lever is pulled.
forward until an audible beep is heard.
Some or all of the LEDs may illuminate
depending on how much pressure (torque)
is being applied.
CAUTION: If any of these features fail the
diagnostic check, take your Lafree to an
authorised Lafree dealer immediately.
Operating Lafree with the Energy Set on, but
with any or all of these features inoperable
could cause severe damage to the electronic
circuitry and could cause you to lose control
and fall.

FIGURE 7C
• Speed sensor: With the support stand in the
down position, lean the bike over slightly until
the rear tyre comes off the ground. Pedal the
crank arm to get the rear wheel turning. If
speed sensor is functioning, an audible beep
will sound repeatedly as the magnetics on
the magnetic “pie” plate are detected by the
sensors until the wheel stops. Stop the rear
wheel with the rear brake. Do not place the
tyre back in contact with the ground while the
rear wheel is moving.
• VPC Throttle: Rotate the right-hand twist
grip. The VPC-throttle functions properly if all
LED’s light up from 1 to 5, depending on how
far the VPC-throttle is turned up. Should one
LED be skipped or fail to light up completely,
your dealer needs to be contacted.
• Torque sensor: Place Lafree on its support
stand. With one hand, put light pressure on
either pedal while holding the rear tyre with
the other hand and rotate the crank arm
To a) cancel Self-Diagnostic mode, b) re-set
Self-Diagnostic mode, c) to turn on Lafree’s
power assist features after using the SelfDiagnostic mode - turn the ignition or the
safety switch to the OFF position, then back to
the ON position.
WARNING: Never ride Lafree in the
Self-Diagnostic mode as it could cause
severe damage to the electronic
circuitry. Lafree’s power assisted pedal
and VPC Throttle will not work while in
the Self-Diagnostic mode.
7.5 Light Emitting Diode (LED)
Energy Level Indicator
Available energy is indicated via a Light
Emitting Diode (LED) string, located on the
top front of the motor housing. When fully
charged, all five LEDs will be illuminated.
LEDs will only illuminate when ignition is on.
As energy is used, fewer LEDs are
illuminated. When only one lit LED remains,
energy level is one percent. If energy level
drops below one percent, motor will
automatically shut down and one LED will
flash. If motor shuts off and single LED begins
flashing, turn ignition to OFF. Do not operate
electric functions until at least a 40 percent
charge (three LEDs illuminated) has been
attained. Charge time for this level is
depending on age of battery and how many
times battery has been charged/discharged.
See Section 6 for more information on battery
charging times.
20
WARNING: Do operate Lafree or leave
ignition in ON position with less than
one percent available energy as
damage will occur to the battery.
LED’s Iluminated Energy Available
1 Light Flashing <1 %
1 1-20 %
2 21-40 %
3 41-60 %
4 61-80 %
5 81-100 %
7.6 Automatic Motor Shut-Off
Lafree is equipped with four automatic motor
shut-off features.
1.Low Energy Shut-Off: If energy level drops
below one percent, motor will automatically
shut down and one LED will flash. If motor
shuts off and one LED begins flashing, turn
ignition to OFF immediately. See Section 6
for more information on battery charging
times.
2.Brake-Actuated Motor Shut-Off: When one
or both of Lafree’s brakes are applied,
electric power assistance (power assisted
pedal, VPC Throttle) automatically
disengages. To resume electric power
assistance, simply release brake(s) and
begin pedalling.
7.7 Front Wheel Quick-Release
Lever Cam
WARNING: Riding with an improperly
adjusted wheel quick-release can allow
the wheel to wobble or disengage from
the bicycle, which may cause damage
to the bicycle and serious injury to the
rider. Therefore, it is essential that you:
1. Ask your dealer for assistance in
installing and removing your wheels
safely.
2. Understand and apply the correct
technique for clamping your wheel
in place with a quick-release.
3. Check that the wheel is securely
clamped in the fork before each and
every ride.
Because of its adjustable nature, it is critical
that you understand how a quick-release lever
cam works and how to use it properly.
While it may appear at first glance to be a nut
and bolt configuration (a long bolt with a lever
on one end and a nut on the other), in fact the
wheel quick-release uses a cam action to
clamp the bike’s wheel in place (Fig. 7D).
FIGURE 7D
3.Speed Motor Shut-Off: When your speed
reaches or exceeds 25 km/h, Lafree’s motor
will automatically disengage and stop
assisting until the speed drops below 25
km/h.
4.In case the motor and/or processor become
overheated, they will disengage; there will
follow a sound and LED1 will flash.
CAUTION: Holding the nut with one hand and
turning the lever like a wing nut with the other
hand until tight will not clamp the wheel safely
in the dropouts. The full force of the cam
action is needed to clamp the wheel securely.
7.7.1 Adjusting the quick-release
mechanism
The wheel’s hub is clamped in place by the
force of the quick-release cam pushing
against one dropout and pulling the tension
21
adjusting nut, by way of the skewer, against
the other dropout. The amount of clamping
force is controlled by the tension adjusting
nut. Turning the tension adjusting nut
clockwise while keeping the cam lever from
rotating increases clamping force; turning it
counterclockwise while keeping the cam lever
from rotating reduces clamping force. Less
than half a turn of the tension adjusting nut
can make the difference between safe
clamping force and unsafe clamping force.
NOTE: Once the quick-release is installed in
the hub axle by the manufacturer or the
dealer, it never needs to be removed unless
the hub itself requires servicing. If the hub
requires servicing, consult your dealer.
7.7.2 Front Wheel Secondary
Retention Devices
Lafree is equipped with a secondary wheel
retention device to keep the wheel from
disengaging if the quick-release is incorrectly
adjusted or the cam opens accidentally.
Secondary retention devices are not a
substitute for correct quick-release adjustment.
Some models are equipped with axle nuts.
For removing the front wheel, loosen the nut
and follow the procedure. For installing the
front wheel, refer to the torque setting table
when fixing the nuts.
FIGURE 7E
Lafree’s secondary retention device is integral
with the fork dropouts and is recessed for the
quick-release lever that keeps the wheel from
dropping out of the fork’s dropouts should the
quick-release lever open accidentally.
However, these tabs are not designed to keep
the wheel in place should the quick-release
lever open accidentally. If you hear or feel
looseness coming from the front wheel, stop
riding immediately and check the quick-release
tension. Ask your dealer to explain Lafree’s
secondary retention device in more detail.
WARNING: Removing or disabling the
secondary retention device is extremely
dangerous and may lead to serious
injury. It also may void the warranty.
WARNING: do not lean Lafree over on
its side when removing the front wheel,
as damage will occur to the lead acid
battery. The only time Lafree’s front
wheel should be removed is to
repair/replace a punctured innertube.
7.7.3 Removing Quick-Release Front
Wheel
(a) Place Lafree’s support stand in its down
and locked position.
(b) Release the front brake’s elbow cable
guide and spread the brake shoes to
allow the front tyre to move in between
them (Fig. 7E).
(c) Rotate the wheel’s quick-release lever
from the locked or CLOSE position (you
can read CLOSE on the lever) to the
OPEN position (you can read OPEN on
the lever) (Figs. 7F, 7G).
(d) Loosen the tension adjusting nut about
six full turns.
(e) Raise the front wheel a few inches off the
ground and tap the top of the wheel with
22
FIGURE 7F
FIGURE 7G
the palm of your hand to knock the wheel
out of the front fork.
(f). Lafree’s support stand will hold the bike
upright, but for additional safety we
recommend that you place a support
under the fork for added stability. Do not
let Lafree rock forward onto the fork so
that the fork is touching the ground as
damage can occur to the lead acid
battery.
WARNING: Lafree’s lead acid battery
must never be laid on it’s side or tilted
in any way. If removing the front wheel,
do not let Lafree rock forward onto the
fork so that the fork is touching the
ground as damage can occur to the
lead acid battery.
(c)
Holding the quick-release lever in the
OPEN position with your right hand,
tighten the tension adjusting nut with your
left hand in a clockwise direction until it is
finger tight against the fork dropout (Fig.
7D).
(d)
While pushing the wheel firmly to the top
of the slots in the fork dropouts, and at the
same time centring the wheel rim in the
fork, rotate the quick-release lever
upwards and push it into the CLOSE
position (Fig. 7G). To do this use the palm
of your hand while wrapping your fingers
around the right fork blade and squeezing
the lever closed using your fingers and
hand together. You have the proper
tension if the lever leaves an impression
in the palm of your hand. The lever should
be parallel to the fork blade/pointing
upward and curved toward the wheel.
CAUTION: If you can fully close the quickrelease without wrapping your fingers around
the fork blade for leverage, and the lever does
not leave a clear imprint in the palm of your
hand, the tension is insufficient. Open the
lever; turn the tension adjusting nut clockwise
a quarter turn; then try again.
(e) If the lever cannot be pushed all the way
to a position parallel to the fork blade,
return the lever to the OPEN position.
Then turn the tension adjusting nut
counterclockwise one-quarter turn and
close the lever again.
7.7.4 Installing a Quick-Release Front
Wheel
(a) Rotate the quick-release lever so that it
curves away from the wheel (Fig. 7C).
This is the OPEN position (you can read
OPEN on the lever).
(b) Remove support from under fork. With the
fork facing forward, insert the wheel
between the fork blades so that the axle
seats firmly to the top of the slots which
are at the tips of the fork blades - the fork
dropouts. The quick-release lever should
be on the left side of the bicycle (Fig. 7F).
(f) Reattach the elbow cable guide to close
the brake shoes; then spin the wheel to
make sure that it is centred in the frame
and clears the brake shoes.
WARNING: Secondary retention
devices are not a substitute for correct
quick-release adjustment. Failure to
properly adjust the quick-release
mechanism can cause the wheel to
wobble or disengage, which could
cause you to lose control and fall,
which may result in serious injury.
23
7.7.5 Removing a Quick Release Rear
Wheel
(a) Standing on left side (in riding position),
disconnect the rear brake.
(See chapter 4).
(b) Shift the rear derailleur to the outermost
position. Pull the derailleur body back with
your right hand. Rotate the quick release
lever to the OPEN position. (Fig 7D).
(c) Lift the rear wheel form the ground, and
with the derailleur still pulled back, push
the wheel forward and down until the
wheel slides from the dropouts.
7.7.6 Installing a Quick Release Rear
Wheel
(a) Shift the rear derailleur to the high gear
(smallest gear on rear wheel) then, pull
the derailleur body back with your right
hand. Rotate the lever to the OPEN
position (Fig. 7D). The lever should be on
the opposite side of the wheel to the
derailleur and the wheel gears.
(b) Put the chain on the top of the smallest
gear. Then, insert the wheel into the
dropouts of Lafree’s frame until the wheel
is aligned with the frame’s seat tube and
there is uniform clearance between the
brake shoes.
(c) Tighten the adjusting nut until it is finger
tight against the frame dropout; then
rotate the lever towards the front of the
bike until it is parallel to the frame’s
seatstay tube and is curved toward the
wheel (Fig. 7H).
FIGURE 7H
NOTE: check the distance between the frame
mounted speed sensor, and the wheel’s
magnet plate at this time. The recommended
distance is 1-2mm.
Some models are equipped with internal gear
hub. Removing and installing the rear wheel
with internal gear hub requires special tools.
Consult your dealer.
7.8 Seat Post Quick-Release
Lafree is equipped with a quick-release seat
post binder for easy seat height adjustment
for a variety of riders. The seat post quickrelease binder works exactly like the wheel
quick-release (Section 7.7). While a quickrelease looks like a long bolt with a lever on
one end and a nut on the other, the quickrelease uses a cam action to firmly clamp the
seat post (Fig. 4B).
WARNING: Riding with an improperly
tightened seat post can allow the
saddle to turn or move and cause you
to lose control and fall. We advise that
you:
1. Ask your dealer to show you how to
correctly clamp your seat post.
2. Learn and apply the correct
technique for clamping your seat
post quick-release.
3. Check that the seat post is securely
clamped before you attempt to ride
your bike.
7.8.1 Adjusting the quick-release
mechanism
The action of the quick-release cam squeezes
the seat collar around the seat post to hold
the seat post securely in place. The amount of
clamping force is controlled by the tension
adjusting nut. Turning the tension adjusting
nut clockwise while keeping the cam lever
from rotating increases clamping force; turning
it counterclockwise while keeping the cam
lever from rotating reduces clamping force.
Less than half a turn of the tension adjusting
nut can make the difference between safe
clamping force and unsafe clamping force.
24
CAUTION: Holding the nut with one hand and
turning the lever like a wing nut until tight will
not clamp the seat post safely. The full force
of the cam action is needed to clamp the seat
post securely.
7.9 Brakes
NOTE: For most effective braking, always
apply both brakes simultaneously.
WARNING: Sudden or excessive
application of the front brake may pitch
the rider over the handlebar, which
may cause serious injury.
WARNING: Always run the Self
Diagnostic test before every ride to
ensure Brake Actuated Motor Shut-Off
feature is operational. Riding Lafree
with a non-operational Brake Actuated
Motor Shut-Off could cause you to lose
control and fall.
7.10 Changing Gears
The gear-changing mechanism on your
bicycle consists of:
• Twist shifter on the left side of the handle bar
• Derailleur with sprocket or internal gear hub
7.9.1 How brakes work
It’s important to your safety that you
instinctively know which brake lever controls
which brake on your bike. The braking action
of a bicycle is a function of the friction between
the brake surfaces - the brake shoes and the
wheel rim on the front brake and internal brake
shoes on the rear roller brake. To make sure
that you have maximum friction available, keep
your wheel rims and brake shoes clean and
free of lubricants, waxes or polishes.
Brakes are designed to control your speed,
not just to stop the bike. Try, as much as
possible, to get used to the (strong) braking
performance during your first ride.
Braking and traction forces change
dramatically when riding on loose surfaces or
in wet weather. Tyre adhesion is reduced, so
the wheels have less cornering and braking
traction and can lock up with less brake force.
Moisture or dirt on the brake shoes can
reduce their ability to slow and stop the wheel
effectively. Riding more slowly will help you
control the bicycle in wet or rough conditions.
7.9.2 Brake Actuated Motor Shut-Off
Lafree is equipped with a special safety
feature that disengages the motor assist any
time the brakes are applied. If you notice
Lafree’s power assisted pedals or VPC
Throttle operating while the brakes are
applied, take it to your authorised Lafree
dealer immediately for service.
7.10.1 What the gears are for
Lafree’s gearing is a simple yet effective way
to help you fine tune your pedal revolutions,
also known as cadence. Lafree’s gearing is
considered mid-range, meaning that it is
designed for rolling, steep terrain. Lafree’s
power assisted pedals and VPC Throttle
motor assist features are effective up to a
maximum of 15 percent grade.
The more you ride, the more proficient you will
become at shifting gears. You will get the
greatest fitness benefit, produce the greatest
sustained power and have the greatest
endurance if you learn to spin the pedals at a
high cadence with low pedal resistance. You
will get the least fitness benefit and have the
least endurance by pushing hard on the
pedals against heavy resistance. At the same
time, this could lead to knee pain and injuries.
Lafree’s power assisted pedals and VPC
Throttle features assist your cadence by
giving you a boost anytime the Energy Set is
on and you are pedalling. However, you
should still use the gears to get the most
performance from your legs and motor assist.
Pedalling in a harder gear will cause the
power assisted pedals torque sensor to use
more energy, which can drain the available
energy stores more quickly.
7.10.2 shifting gears with derailleur
First and foremost, you must be pedalling
forward to shift the drive chain from one gear
to another.
25
FIGURE 7I
CAUTION: Never move the shifter while
pedalling backward, nor pedal backward after
having moved the shifter. This could jam the
chain and cause serious damage to the
bicycle, which could also cause you to lose
control and fall.
Lafree is equipped with a specially designed
twist shifter, located on the left side of the
handlebar to the inside of the left grip. To shift
the drive chain into a higher gear (smaller
cog) and make pedal resistance harder, rotate
the shifter to a higher number on the gear
indicator. To shift the drive chain into a lower
gear (larger cog) and make pedal resistance
easier, rotate the shifter to a lower number on
the gear indicator (Fig. 7I).
utilise this technique could cause damage to
the drive chain and cogs.
7.10.3 Shifting gears with internal
gear hub
With gear hub you shift the same as with
derailleur. Pedal along easily without putting
pressure on the pedals. However, with gear
hubs it is possible to shift while free wheeling
or standing still. For proper performance make
sure the VPC throttle is not engaged during
shifting gears. Gear indication is the same as
with derailleur: lower numbers for low speed,
up hill and head wind, higher numbers for
high speed, down hill and tail wind.
7.11 Tyres and Innertubes
7.11.1 Tyres
Lafree’s tyres are general-purpose in design,
made for improved (paved) road surfaces.
They are not designed for unimproved roads
or trails where dirt, loose rocks, or other loose
debris is present. Your dealer can help you
select new tyres once they warrant
replacement.
To best facilitate gear shifts, always shift
gears before you are on a hill. Always scan
the road or path for upcoming hills and be
prepared to shift early, before the grade of the
hill becomes too steep.
If pedalling becomes too difficult, engage VPC
Throttle by twisting rearward/clockwise on the
right-hand throttle grip while continuing to
pedal forward, but without pressure to the
pedals. While pedalling, rotate the left-hand
twist shifter forward/counterclockwise to shift
the drive chain into an easier gear. Once in an
easier gear, disengage VPC Throttle by
rotating the throttle forward/clockwise and
resuming power assisted pedal by putting
manual power to the pedals.
Whenever shifting gears, shift early, before
pedal pressure becomes harder. Failure to
FIGURE 7J
The size and pressure rating are marked on
the sidewall of the tyre (Fig. 7J). The part of
this information which is most important to you
is tyre pressure.
The best way to inflate a bicycle tyre to the
correct pressure is with a bicycle pump. Your
dealer can help you select an appropriate
pump.
26
7.11.2 Tyre Air Valves
Lafree tyres have French valves. To inflate a
French valve tube, loosen the little centre nut
a few turns. By pushing the centre nut
downwards you can remove air from the tube.
Make sure the pump matches the valve type.
Contact your dealer if necessary.
7.12 Suspension
Some Lafree models are equipped with a front
suspension fork. This suspension is designed
to smooth out some of the bump forces
associated with roads and paths. It is not
designed to be used for jumping or other
excessively abusive riding.
The suspension fork on Lafree is a closed
unit, utilising a coil spring and elastomer
bumper system. It is not designed to be user
adjustable or serviceable. If, after riding Lafree
for a given period, the front suspension seems
to be working insufficiently, take your Lafree to
an authorised Lafree dealer for inspection.
FIGURE 7L
7.14 Support Stand
Lafree is equipped with a retractable (spring
loaded) support stand for parking and storage
while not in use. It is extremely important that
you always use the support stand when
parking or storing Lafree.
Never lean Lafree against anything (wall, post,
fence, etc.), or lay Lafree on it’s side.
7.13 Rear fork lock
Operating the rear fork lock mechanism (Fig
7K): Push the lock pin slightly in the direction
of the pin. Now rotate the pin through the
wheel. Make sure not to touch the spokes.
Click the pin firmly into the lock. Now you can
remove the key. To open the lock, make sure
the pin can rotate freely. Then, simply place
and turn the key.
FIGURE 7K
To park Lafree, step down on the support’s
stand toe. Guide the Lafree backwards while
pressing the toe further down until the support
locks (Fig 7L). To ride Lafree again, put your
foot in front of the support stand and move the
bike with care forward.

SERVICE & MAINTENANCE
NOTE: Technological advances have made
bicycles and bicycle components more
sophisticated than ever before, and the pace
of innovation is increasing. This on-going
evolution makes it impossible for this manual
to provide all the information required to
properly repair and/or maintain your bicycle. In
order to help minimise the chances of an
accident and possible injury, it is critical that
you have any repair or maintenance which is
not specifically described in this manual
performed by your dealer.
Equally important is that your individual
maintenance requirements will be determined
by everything from your riding style to
geographic location. Consult your dealer for
help in determining your maintenance
requirements.
The amount and kinds of maintenance you
can do yourself depends on your level of skill
and experience, and on whether you have the
special tools required.
WARNING: Many bicycle service and
repair tasks require special knowledge
and tools. Do not begin any
adjustments or service on your bicycle
if you have the slightest doubt about
your ability to properly complete them.
Improper adjustment or service may
result in damage to the bicycle or in an
accident which may cause serious
injury.
If you want to learn about service and repair
work on your bike, you have two options:
Regardless of which option you select, we
recommend that the first time you work on
something on your bike, ask your dealer to
check the quality of your work before you
attempt to ride the bike. There may be a small
labour charge for this service.
8.1 Service & Maintenance
Schedule
Some service and maintenance can and
should be performed by the owner, and
require no special tools or knowledge beyond
what is presented in this manual.
The following are examples of the type of
service you can perform yourself. All other
service, maintenance and repair should be
performed in a properly equipped facility by a
qualified bicycle mechanic using the correct
tools and procedures specified by the
manufacturer.
1. Break-in Period: Your bike will last longer
and work better if you break it in before riding
it hard. Control cables and wheel spokes may
stretch or “seat” when a new bike is first used
and may require readjustment by your dealer.
Your Mechanical Safety Check (Section 4.3)
will help you identify some things that need
readjustment. But even if everything seems
fine to you, it’s best to take your bike back to
the dealer for a check-up. Dealers suggest
you to bring the bike in for a check-up after 30
days. Another way to judge when it’s time for
the first check-up is to bring the bike in after
about 10 to 15 hours of use. But if you think
something is wrong with the bike, take it to
your dealer before riding it again.
1.Ask your dealer to recommend a book on
bicycle repair.
2.Ask your dealer about the availability of
bicycle repair courses in your area, or
through the bike shop.
2. Before every ride: Mechanical Safety
Check (see Section 4.3)
3. After every long or hard ride; if the bike has
been exposed to water or grit; or at least
every 150 kilometres: Clean the bike and
lightly oil the chain, freewheel cogs and rear
28
derailleur pulley bushings. Wipe off excess oil.
Lubrication is a function of climate. Talk to
your dealer about the best lubricants and the
recommended lubrication frequency for your
area.
4. After every long / hard ride or after 10 to 20
hours of riding:
• Squeeze and hold the front brake and rock
the bike forward and back. If you feel a
clanking or looseness with each forward or
backward movement of the bike, you may
have a loose headset. Have your dealer
check it. Asmall amount of play may be
present from the suspension fork’s
overlapping slider mechanisms, which is
normal. However, if you feel a significant
amount of looseness or play, have your
dealer check it immediately.
• Lift the front wheel off the ground and turn
the handlebar to the left and to the right a
few times. If you feel any binding or
roughness in the steering, you may have a
tight headset or the headset may need to
have grease added to the ball bearings.
Please ask your dealer to check it.
•
Hold one pedal and rock it back and forth
across the centreline of the bike; then do the
same with the other pedal. If anything feels
loose. Please ask your dealer to check it.
your dealer check the wheel for tension and
trueness.
• Check the frame (particularly in the area
around all weld joints), the handlebar, the
stem and the seatpost for any deep
scratches, cracks or discoloration. These
are signs of stress-related fatigue and
indicate that a part is at the end of its useful
life and needs to be replaced.
• Check to make sure that all parts and
accessories are still secure, and tighten any
which are not.
5. As required: If either brake lever fails the
Mechanical Safety Check (Section 4.3):
restore brake lever travel by turning the brake
cable adjusting barrel counterclockwise, then
lock the adjustment in by turning the barrel’s
lock nut clockwise as far as it will go. If the
lever still fails the Mechanical Safety Check,
ask your dealer to check the brakes.
If the chain won’t shift smoothly and quietly
from gear to gear: the derailleur may be out of
adjustment. The cause may be as simple as a
stretched control wire, in which case you can
compensate by rotating the shifter or
derailleur cable adjusting barrel
counterclockwise one turn. Try shifting again.
If a full turn of the cable adjusting barrel does
not cure the problem, see your dealer.
• Take a look at the brake shoes. If they’re
starting to look worn or are not hitting the
wheel rim squarely, ask your dealer to
adjust or replace them.
• Check the control cables and cable
housings for any rust, kinks, or fraying. If
you notice any of these problems or if your
brakes and/or shifter are not functioning
smoothly, ask your dealer to check and
replace the cables and/or wires if
necessary.
• Squeeze spokes in adjoining pairs on either
side of each wheel between your thumb
and index finger. They should all have about
the same “tension.” If any feel loose, have
6. Every 50 hours of riding: Take your bike to
your dealer for a check-up.

PRECAUTIONS AND PROCEDURES
You should never go for a bike ride without
the following emergency equipment and
knowledge:
• Allen wrenches (4, 5 and 6mm), used to
tighten various clamping bolts that may
loosen
• Patch kit and a spare inner tube
• Tyre levers
• Tyre pump or cartridge inflator with correct
head to fit your tyre valves
• Identification (address, phone number,
insurance company, emergency contact,
blood type, medical allergies and
conditions)
1. If you get a flat tyre: let all the air out of the
innertube (Section 7.11). Remove one side of
the tyre from the rim by inserting a tyre lever
in between the rim and base of the tyre’s
sidewall (“bead”). Pry the bead away from the
rim by pushing down on the tyre lever. Take
another tyre lever and pry the bead off the rim
approximately 10 to 15 centimetres away
from where you started. Athird lever may be
needed, but at this point you should be able
to begin levering the bead off the rim so that
the entire circumference of one side of the
tyre bead comes off the rim.
Remove the innertube by first removing the
air valve from the rim’s valve hole, then
removing the innertube. Carefully check the
outside and inside of the tyre for the cause of
the puncture (thorn, glass shard, nail, etc.)
and remove the object if it is still there. If the
tyre is cut, line the inside of the tyre in the
area of the cut with something that will resist
the innertube forcing its way out of the cut
once inflated-a spare patch, a piece of inner
tube, a dollar bill, an energy bar wrapper, a
piece of plastic milk carton, etc.
Either patch the tube (follow the instructions
in your patch kit), or use a new innertube. (It
is always a good idea to have a new
innertube as well as a patch kit in case the
innertube cannot be patched.)
tire needs to be applied, the wheel needs to
be disassembled.
Before replacing the new/repaired innertube,
put just enough air in to give it some shape.
Starting with the air valve, install the
innertube into the tyre. Then, starting at the
valve, slip the exposed tyre bead into the rim
using downward pressure. Make sure the
bead seats down below the valve’s thick
rubber base. Next, push the tyre’s bead
down into the rim with your thumbs along
either side of the circumference of the rim,
not just one side. Make sure the innertube is
not being pinched by the bead. If you have
trouble getting the last few inches of bead
over the edge of the rim with thumb
pressure, use a tyre lever and be careful not
to pinch the tube.
CAUTION: Do not use a screwdriver or any
tool other than a tyre lever, as you are likely to
pinch and puncture the innertube.
Check to make sure the tyre is evenly seated
around both sides of the rim and that the
innertube is inside the tyre beads. Push the
valve stem into the tyre to make sure that its
base is seated within the tyre’s beads. Inflate
the tube slowly to the optimum pressure, all
the while checking to make sure that the tyre
beads stay seated in the rim. Replace the
valve cap. Replace the wheel in the bike (see
Section 7.7).
WARNING: Riding your Lafree with a
flat or under-inflated tyre can seriously
damage the rim, tyre, tube and bicycle,
and can cause you to lose control and
fall.
In case a new

2. If you break a spoke: Awheel with a loose
or broken spoke is much weaker than a fully
tensioned wheel. If you break a spoke while
on a ride, you will have to ride much more
slowly and carefully as the weakened wheel
could experience additional broken spokes
and become useless.
WARNING: A broken spoke seriously
weakens the wheel and may cause it to
wobble, striking the brakes or the
frame. Riding with a broken spoke(s)
can cause you to lose control and fall.
Twist the broken spoke around the spoke next
to it to keep it from flopping around and
getting caught between the wheel and the
frame. Spin the wheel to see if the rim clears
the brake shoes/frame. If the wheel will not
turn because it is rubbing against the front
brake shoe(s), try turning the brake cable
adjusting barrel(s) clockwise to slacken the
cable and open up the brakes (see Section
4.3.4). If the wheel still won’t turn, open the
brake’s quick-release (see Section 7.7) and
secure any loose cable as best you can. Walk
the bike, or if you must, ride it with extreme
caution. However, it is strongly recommended
that you do not ride with only one functioning
brake, and that you never ride with two nonoperational brakes.
are involved with another vehicle, get as much
information as possible from the involved
party and any witnesses.
Next, check your bike for damage, and fix
what you can.
When you get home, carefully perform the
checks described in Section 7 and check for
any other damaged parts. All bent, scored or
discoloured parts are suspect and should be
replaced.
WARNING: A crash can put
extraordinary stress on bicycle
components, causing them to fatigue
prematurely. Components suffering
from stress fatigue can fail suddenly
and catastrophically, which may cause
loss of control or serious injury.
CAUTION: If you have any doubt about the
condition of the bicycle or any of its parts,
take it to your dealer for a thorough check.
Checking the frame regularly and bringing any
questionable marks to the attention of your
Lafree dealer or other qualified person will
prolong the safe use of your frame and
components.
3. If you crash: First, check yourself for
injuries. Seek medical help if necessary. If you
