Never leave the product unattended.
6 Product description / purpose
The product is a compact bike comprising a
drive unit and a product frame that is
designated as chassis. The user lies in the
product and propels using crank movements
with their hands and arms.
The product assists the user with their mobility.
It is easier to cover longer distances with
ergonomic movement processes (similar to
using one's own wheelchair) and it is also
possible to take bicycle tours with pedestrians.
This expands the activity radius. Uneven
terrain can also be travelled on due to the
larger the product wheels. The downhill speed
can be regulated via the product's braking
systems, so that downhill slopes can be
travelled on safely.
When hand-biking, the seating posture in the
wheelchair as well as the static straighten the
spinal column are promoted by a
physiologically sensible and ergonomic training
of your arms. Moreover, the shoulder joints are
relieved sufficiently compared with the usual
propulsion of a wheelchair using the handrims.
In the medium term, the body musculature is
built up and thus, possible consequential harm
that may be caused by propelling only on the
one side (only via the handrims) is
counteracted effectively.
For safety reasons, the product may only be
operated by persons who
have been trained in its use by the dealer
or PRO ACTIV.
can move and control their hands and
arms so that they are able to operate the
controls and perform the full steering
movement without restrictions while
driving.
are physically and mentally capable of
safely operating the device in all operating
situations and can meet the legal
requirements for use on public roads.
7 Acceptable usage and operating
conditions / places of use
Use the product on paved surfaces. Avoid
driving on unpaved or loose surfaces (e.g. on
loose gravel, in sand, mud, snow, ice or
through deep puddles of water), as this may
result in incalculable risks.
The product must be equipped in accordance
with road traffic regulations when operated on
public roads and spaces.
The maximum permitted load of the product in
its standard design is a 100 kg payload.
Individual customisation can be made to
accommodate a higher load; this will be
indicated on the ratings plate. Please ensure
that the load limit indicated on the ratings plate
is not exceeded when transporting objects.
We recommend: Always use the safety
pennon or warning flag when participating in
public traffic with the product otherwise there is
an easy risk of being overseen due to the very
low sitting position.

12 Safety instructions –
prior to driving / use
Before every trip, check the condition of
the wheels (e.g. visual inspection of the spokes
and rims, check the tyres for damage, foreign
bodies and crack formation). If you have any
doubts about the serviceability of the product,
stop using it. In this case, contact your dealer
or PRO ACTIV.
Check tyre pressures at regular intervals.
Ensure that you comply with the
manufacturer's specifications which can be
found on the tyres. Tyre pressure which is too
low has a negative effect on the handling.
Before each trip, check the safe locking of
the wheels and adaptation of the drive unit.
Secure the safety cord to the lever of the
eccentric pin. The use without the safety cord
attached is not permitted (see chapter 22).
Before starting your trip check that the
product's brake functions. If all existing brakes
are not fully functional, no trips may be taken.
Check the stable condition of the seat and
back upholstery at regular intervals and in case
of doubt, have your dealer assess its condition.
Always ensure that your feet cannot slip
out off the leg rest and make contact with the
drive wheel when using the product, if
necessary by using a special fixation device
(e.g., using the hook-and-loop straps included
in the scope of supply).
If present, check the function of the front
and rear lights as well as the effectiveness of
the side and rear reflectors before every trip.
Lights and reflectors must be clearly visible
during the journey and must not be covered by
other objects. Especially trips that take place in
the dark or in the twilight, the lighting must be
functional and visible. For longer trips in the
dark, we recommend that you also take along
extra batteries.
To minimise the risk of suffering serious
head injuries in the event of a fall, a helmet
should always be worn when driving with the
product.
When travelling, always carry a repair kit
and tyre pump for repairs in event of
punctured / flat tyre. A alternative to this is a
pump spray that fills your tyre with a foam that
hardens in the tyre.
13 Safety instructions – while
driving / using
Always hold onto the crank handles with
both hands while driving. If the driving situation
requires you to take one hand off the crank
handles, this is only permitted when the speed
has been reduced to the minimum possible
beforehand.
Increase the speed slowly up to the
desired speed.
Use particular caution when approaching
stairs, edges, drops or other hazard areas.
When waiting at potential hazard areas
(e.g. while waiting at a pedestrian crossing, on
hills or slopes or at ramps of any type), always
hold down the service brakes.
When driving round a bend, reduce your
speed to a minimum.
Do not ride parallel to slopes due to the
risk of tipping.
You may only drive on slopes where the
product can be safely controlled by steering
and braking of the product.
Do not attach objects (carrier bags, etc.)
to the product. These could prevent safe
operation of the product while driving.
When driving on areas which are used for
pedestrians, observe the maximum permitted
speed (walking speed 6 km/h) and keep a
sufficient distance (at least the width of the
product) from the kerbs or other obstacles and
other road users.
Operating instructions NJ1 & FREAK Compact bike
9
When driving on public roads and paths,
the provisions of the road traffic regulations
(German StVO) must be observed.
Avoid driving on unpaved or loose
surfaces (e.g. on loose gravel, in sand, mud,
snow, ice or through deep puddles of water).
When travelling on poorly maintained
paths (e.g., large gravel, potholes) there is an
increased risk of puncturing your tyres as well
as tipping.
If you encounter new driving situations
which are unknown to you, approach them with
great care. If you consider that the risk is too
high, you must immediately abort the driving
manoeuvre and, if required, call for help to
assist you in extracting yourself from this
situation.
You must not make telephone calls while
driving.
Operating the product can affect other
devices, for example theft protection barriers in
department stores.
When driving, never jerk the handlebars to
the left or the right, as this may cause the
product to tip over sideways in certain
circumstances.
While driving, never grab onto the area of
the wheel, in the area of the chain / sprockets /
chain wheels or into other rotating parts; if you
do you may cause injuries.
Only brake the product using the service
brakes.
During long trips the brakes of the product
may heat up. Therefore, do not touch the
brakes during or immediately after the trip (e.g.
when detaching the drive unit or loading the
product).
If the situation allows it, the speed should
be reduced by carefully applying the service
brake. Abrupt braking can cause the upper
body to fall forwards which can thereby result
in injuries or loss of vehicle control.
The product is only designed to be used to
transport persons with limited mobility and
must not be used for any other purpose, e.g.
by playing children or to transport goods.
If the weight load on the drive wheel falls
(e.g. when driving on slopes) or when driving
on loose / slippery surfaces, the braking action
of the wheel may be considerably reduced.
The driving style and speed should be adjusted
so that the product can be safely stopped at all
times using the brakes.
Always check the tight fit of the eccentric
pin and the securing cord.
Make sure that cables and lines are not
kinked or caught up somewhere. This could
cause them to be damaged which could lead to
the brakes and gear shift not working correctly.
In this case, the product must no longer be
operated.
Smoking when riding is forbidden as the
seat and back system may be damaged from
ash falling down.
When the product is exposed to direct sun
radiation or low temperatures for longer
periods, take note that the parts of the product
may become very hot (>41°C) or very cold
(<0°C).
14 Safety instructions regarding
obstacles
Driving on steps with the product is
forbidden.
Obstacles like curbs, for example, should
always be negotiated driving forwards and
always using the minimum speed required.
The ground clearance is decisive with
regard to negotiable obstacle heights. You will
find ground clearance in chapter 8.3.
Operating instructions NJ1 & FREAK Compact bike
10
When driving over or passing obstacles, it
is important that you avoid any product or body
parts catching on the obstacle as this may lead
to falling causing serious injuries to the user
and third parties as well as damage to the
product.
Always drive over curbs or other obstacles
so that you cross them to the front or at right
angles. If you approach them at an angle, or
only have one rear wheel on the obstacle,
there is an increased risk of tipping over to the
side which can result in serious injuries to the
user and third-parties as well as damage to the
product.
15 Safety instructions regarding
dangerous locations and
dangerous situations
The operator of the product determines the
route to be driven taking the operating
instructions, their driving knowledge and
physical abilities into consideration.
The personal driving skills are particularly
important in the following dangerous locations
which are provided as examples; the product's
user must use their judgement before driving in
such locations:
quay walls, landing and berthing locations,
paths and locations close to water,
unsecured bridges and dykes.
narrow paths, slopes (e.g. ramps and
driveways), narrow paths on a slope,
mountainous routes.
narrow and / or steeply sloping paths along
main roads or near cliffs.
routes which are covered in leaves, snow
or ice.
ramps and lifting equipment on vehicles.
When driving in a circle or turning on hills
or downward slopes, there may be an
increased tendency to tip over to the side due
to the changes in the centre of gravity. Always
perform these driving manoeuvres with
increased caution and only at slow speed. If
required, the driving manoeuvre must not be
performed or only with the help of an assistant.
When crossing main roads, intersections
and level crossings, extreme caution is
needed. Crossing rails in the road or at level
crossings must never be undertaken when
travelling parallel to them, as otherwise the
wheels could become caught which would
result in the product being unable to
manoeuvre.
When driving on ramps and lifting
equipment on vehicles, extreme caution is
needed. During the lifting or lowering operation
of a ramp or the lifting equipment, the service
brake should be operated. This prevents rolling
away.
The grip of the tyres on the ground is
reduced in the wet. There is an increased risk
of slipping. Adjust your driving, braking and
steering behaviour accordingly.
16 Functional elements
16.1 Pedal bearing support & crank
16.1.1 Seating position
The seating position and therefore the pedal
position and the crank length depend on the
upper-body stability or the core musculature as
well as the body size. A suitable adjustment
will have been made during the consultation /
measurement procedure.
The pedal position should be selected as low
as possible where the cranks however, must
not touch the users thigh when it is turning.
Moreover, the elbows should not be completely
extended when the crank handles point
completely forward away from the body and
the shoulders should rest against the backrest.
With weak core musculature, the seating
position and the crank length should normally
be chosen so that the upper body remains still
and always has a fixed contact with the
backrest when operating the crank while
driving. This is particularly important if you
Operating instructions NJ1 & FREAK Compact bike
11
have low seating stability due to missing or
weak core musculature. A rocking motion
(forwards and backwards) of the upper body or
the head should be avoided where possible.
For this, the correct setting of the backrest (see
chapter 17) and the correct choice of the crank
length as well as the pedal position is decisive.
If necessary, you should also use a hip strap or
chest strap for stabilising.
Figure 3: Elbows are not stretched completely
Figure 4: Distance between the crank and the thigh
The cranks must not touch the thigh when
they are being turned.
The elbows should not be completely
extended when the crank handles point
completely forward away from the body and
the shoulders should rest against the backrest.
16.1.2 Pedal bearing position
When equipping the product with a pedal
bearing support that cannot be adjusted, a
subsequent adjustment of the pedal bearing
position can only be achieved by exchanging
the pedal bearing support.
The pedal bearing support can be exchanged
by loosening the four M6 fastening screws
(AF 5 mm) on the tip fork bridge and the four
M6 fastening screws (AF 4 mm) on the pedal
bearing housing. Then the new pedal bearing
support with another length can be inserted
and the 8 fastening screws tightened up to
7 Nm and secured with thread lock fluid.

Operating instructions NJ1 & FREAK Compact bike
12
If your product is fitted with an adjustable
pedal bearing support (optional), the pedal
bearing position can be adjusted in angle and
height:
The angle adjustment is done at the top
fork bridge. To do this, loosen the four M6
fixing screws (AF 5 mm), on the clamp
slightly so that the pedal bearing support's
angle can be adjusted using minimal force.
The angle adjustment is continuous (as a
guide, there is a 12° scale fitted). When
you have finished adjusting the angle,
tighten up the four M6 fixing screws
(AF 5 mm) to 7 Nm torque and secure
them with thread lock fluid.
To adjust the height, two M6 fixing screws
(AF 5 mm) must be loosened on the pedal
bearing housing. Then the pedal bearing
housing can be moved along the pedal
bearing support to the desired position.
Then tighten up the four M6 fixing screws
(AF 5 mm) to 7 Nm torque and secure
them with thread lock fluid.
Figure 7: M6 fixing screws for angle and height
adjustment of the pedal bearing position
If you want to make a change to the pedal
bearing position, please contact your dealer or
PRO ACTIV.
Please note that, after a large adjustment
to the chain pedal bearing position, the lines
and the cable lengths must be adjusted.
16.1.3 Crank length and grip width
The crank length can be chosen from different
lengths individually to suit the length of the
arms and mobility of the user. Different widths
of pedal bearing shafts and spacers between
the crank handles and the rotary axles of the
hand grips are available to adjust the grip
width.
If you want to make a change to the crank
length or grip width, please contact your dealer
or PRO ACTIV.
Figure 8: Crank length and grip width
16.2 Grips
The grips must be held firmly with both hands
whilst driving and always held so that the
cables and lines are oriented upwards.

The cables for the Rohloff hub drive are an
exception for this. If the handles are held
correctly they point forwards into the direction
of travel.

hub drive
16.3 Gear shift
16.3.1 Chain shift
For the chain shift, shifting procedures can
only occur while the crank is moving. Changing
the gear with the cranks stationary is not
possible. In general, the torque applied to the
cranks should be reduced briefly while
changing the gear so that the gear change can
happen more quickly.
The controls for the gear change are normally
designed so that they can be operated using
thumb / index finger switching fittings. With
the 9-speed cassette at the bottom, switching
to the next largest sprocket means a lower or
easier gear, and to the next smallest sprocket
to a larger or more difficult gear. For the 3speed chain wheels at the top, the behaviour is
exactly the opposite.
Figure 11: 9-speed cassette and 3-speed chain
wheels
With the thumb / index finger switching fittings,
gear changes are achieved by:
"Thumb switch" – operation by pressing in
the direction of travel with the thumb
"Index finger switch" – operation normally

Operation of the chain shift is also possible
using a grip shift (optional). Here, you can
change between the 3-speed chain wheels by
turning the left-hand twist grip. On the righthand grip, you can change between the
sprockets in the 9-speed cassette.
There is no display for the gear selected
available. You can only read-off which chain
wheel / sprocket is currently being used on the
twist grips.
Figure 14: Shifting using the twist grip
When driving up a hill, it should be noted
that it is only possible to change using the 9speed cassette under heavy loads on the
chain. Changing using the top three chain
wheels is no longer possible if there is heavy
tension on the chain. It is therefore important to
switch to a smaller chain wheel as a
precaution.
Try to avoid selecting cross gears, as the
efficiency and service life of the chain will fall
significantly (more information can be found in
chapter 32).
For more information, please see the
instructions provided by the gear manufacturer.
16.3.2 Hub gears
The hub drive can be changed while driving
and also when stationary. No crank movement
is needed to change or only a small reduction
in torque is needed while driving.
The Rohloff hub drive and Shimano Nexus
hub drives are operated by turning the grip
shift. The gear selected is shown in the
display on the control panel.

16.4 Brakes
Normally there is one disc and one rim brake
fitted to the product. Where possible, both
brakes should be operated simultaneously and
the braking requirement reduced by driving in a
way that anticipates the requirement to reduce
speed if necessary.
16.4.1 Rim and disc brakes
The brakes are operated using the brake lever.
Figure 27: Brake lever
In the event of abrupt hard braking, there
is a risk that you might fall forward with your
upper body and thereby cause injuries to
yourself.
Please make sure that the braking
surfaces on the rim, the brake disks and the
brake pads on the rim breaks do not come into
contact with oils or greases which could
otherwise impair the braking effect. If rims,
brake discs or brake pads do come into
contact with oils or greases, the brake pads
must be replaced and the brake disc and rim
must be professionally cleaned with brake
cleaner (e.g., Weicon surface cleaner).
You can find further information in the brake
manufacturer's instructions.
16.4.2 Back-pedal brake for hub drives
A back-pedal brake is already integrated into
the Shimano Nexus Inter7 and 8 speed hub
drives.
This brake is operated by moving the cranks
against the acceleration direction. The brake
force applied is adjusted by the strength of the
backwards movement of the cranks.

16.4.3 Parking brake
Using the aluminium bracket which is
attached to the pedal bearing support, one of
the two brakes can be used as a parking
brake. For this purpose, the aluminium bracket
is clamped over the grip and the brake lever
while the brake lever is depressed.
Figure 28: Aluminium bracket as a parking brake
As an option, the parking brake can be
selected via the operating handle operated.
The parking brake is implemented via the
mounted rim brake. The operation of the
parking brake is carried out using an operating
lever on the pedal bearing support. If the
operating lever is pressed to the left, the rim
brake is activated. When pressed further to the
left, the brake force increases even more. If the
operating lever is pressed to the right, the rim
brake is opened again.
Figure 29: Parking brake can be operated from the
operating lever (opened)
16.5 PRO ACTIV back-pedal brake &
crank release function
16.5.1 Operation
The PRO ACTIV back-pedal brake can be
used for chain gears or hub drives with a
freewheel.
The PRO ACTIV back-pedal brake is a closed
hydraulic system consisting of a generator unit
and a disc brake calliper. The system has
automatic wear compensation for the brake
pads.
To adapt the system to your body weight and
the physical limitations of the driver, the
springs of the system are available in three
strengths. These can also be replaced
retrospectively. Contact your dealer
immediately who will arrange the replacement
of the springs by PRO ACTIV.
The back-pedal brake is delivered with a crank
release function which allows reverse driving
and manoeuvring via the running wheel or by
supporting on the ground. As: For functional
reasons, the back-pedal brake always acts as
soon as the product moves backwards.
Therefore, the driver must first unlock the
Aluminium bracket as a
parking brake

reverse movement by operating the crank
release function.
The braking function via the backward
movement (crank movement against the
direction of acceleration) is always guaranteed
– with the crank release function activated or
deactivated.
The crank release function can also be
selected in combination with the Shimano
Nexus Inter7 and 8 hub drives (which already
have back-pedal brakes) so that it is possible
to reverse and manoeuvre. The back-pedal
brake is implemented here via the hub drive. In
this case it must be ensured that the hub
drive's back-pedal brake is not operational
when the crank release function is activated. If
you want to brake with the activated crank
release function, this is only possible via the
additional braking system such as a rim brake.
Figure 30: Generator unit PRO ACTIV back-pedal
brake
16.5.2 Operation
The brake is operated by pushing the cranks
backwards. The brake force applied is adjusted
by the strength of the backwards movement of
the cranks.
The crank release function is operated by
pressing the side pressure plate. To activate
the crank release function, the left-hand
pressure plate must be operated (seen from
the direction of travel). To return to normal
driving operation with the back-pedal brake,
the right-hand pressure plate must be
operated.
Figure 31: Left- and right-hand pressure plates
16.5.3 Safety instructions
Before every trip, perform a brake test
while stationary by moving the cranks with the
normal operating force in the opposite direction
to acceleration. The drive wheel must not be
able to move when the system is operated.
At regular intervals, check that all of the
connections, lines, bleed screws and the
surface of the transmitter unit do not leak and
that all the screw connections on the brake
system are tightened securely.
At regular intervals, check that the brake
pads and discs are free from grease, oil or
other contamination. In addition, check the
thickness of the brake disc. The minimum
thickness is printed on the brake disc. In
addition, the brake pad thickness must be
checked with a measuring calliper. The
minimum pad thickness plus support material
is 2.5 mm. Measure the pad thickness at the
thinnest point.
Do not drive if your brake system is faulty
in one of the previously listed points. Contact
your dealer immediately who will arrange
maintenance by PRO ACTIV.

17 Backrest
17.1 Angle adjustment of the backrest
For adjusting the angle of the backrest, open
the clamp lever by turning counter-clockwise (a
half to a complete rotation). Then the backrest
can be moved forwards of backwards. The
length of the backrest support changes during
the movement of the backrest.
Once the desired angle of the backrest is set,
hold the backrest in this position and then
close the clamp lever again clockwise with a
half to complete rotation.
Figure 32: Angle adjustment of the backrest via the
clamp lever
If the clamp lever rests on the frame of the
product when turning, you have the option of
pulling the clamp lever out vertically to the
rotating axis and to let go into another angled
position via the integrated serration, and keep
on turning.

17.2 Longitudinal positioning of the
backrest
Figure 34: Clamp for the longitudinal positioning of
the backrest
The longitudinal positioning of the backrest (or
distance for the backrest to the pedal bearing)
can be carried out by undoing two M6 fixing
screws (AF 5 mm) each on the right and left
side of the product frame. After undoing a total
of four M6 fixing screws (AF 5 mm), both
clamps on the product frame can be moved to
the desired position.
In doing so, take note:
when the product is equipped with seat
upholstery "Open belt system", the
backrest can be pushed forwards and
backwards. when equipped with seat
upholstery "Body Contour", the backrest
can only be pushed backwards so that the
distance between the backrest and the
pedal bearing is increased.
The clamps on the right and left side must
be positioned at the same height of the
product frame.
Figure 35: Longitudinal adjustment of the backrest
via M6 fixing screws and clamps on the frame of the
product
Once the desired longitudinal position of the
backrest has been found, the four M6 fixing
screws (AF 5 mm) are tightened to 7 Nm again
and secured using screw locking fluid.
After an adjustment of the longitudinal
position of the backrest, a check should be
made if the seat system should be changed
with regard to the new dimension.
18 Seat system
The seat system generally either comprises a
spring suspended Body Contour seat
upholstery or an open belt system.
With a seating system from Body Contour
seat upholstery, there is no adjustment
option. The Body Contour seat upholstery has
a springing effect and when seating,
automatically forms a slack.
Figure 36: Body Contour seat upholstery

Operating instructions NJ1 & FREAK Compact bike
22
The open belt system can be subsequently
adjusted. The slack of the seating surface can
be changed using Velcro straps.
Figure 37: Open belt system with Velcro straps for
adjusting the slack
With "Open belt system" seating system:
when adjusting the slack of the belt system,
take care that the slack does not protrude
beyond the lower edge of the frame. Otherwise
when overcoming obstacles, you may get
caught the belt system and your bottom that
may result in injury and damage to the belt
system. The product may not be operated with
damaged seating system.
It is mandatory to use a seat cushion on
the seating system. At cold temperatures, the
seat cushion prevents the lower abdomen from
under-cooling and protects against dirt and
wetness. Moreover, the seat cushion also
ensures for equal pressure distribution.
19 Neck rest
19.1 Neck rest height adjustment
To adjust the height of the neck rest, two M6
fixing screws (AF 5 mm) have be loosened on
the neck rest holding tube. Then the height of
the neck rest holding tube can be adjusted.
Once the desired height has been found, the
two M6 fixing screws (AF 5 mm) are tightened
to 7 Nm again and secured using screw
locking fluid.
Figure 38: Height adjustment of the neck rest via
two M6 fixing screws on the neck rest holding tube
19.2 Neck rest angle adjustment
The angle adjustment of the neck rest is
carried out via the clamp lever on the neck rest
holding tube. Open the quick release lever and
set the neck rest padding to the desired angle.
Then close the quick release lever again.

20.3 Adjusting the length of the
collision guard
When mounting running wheels with another
tyre size, the length of the collision guard may
have to be adapted. For this purpose, undo
both M6 fixing screws (AF 4 mm) on the right
and left inlet. Now the collision guard can be
pushed along the inlet and another borehole
can be used for the fixing screws.

Once the correct position of the inlet has been
found, both M6 fixing screws (AF 4 mm) are
tightened to 7 Nm again and secured using
screw locking fluid.
21 Running wheels
21.1 Removing and attaching the
running wheels
Figure 47: Locking knob in the middle of the wheel
axle
To remove the running wheels grip through
the spokes around the wheel hub with your
fingers. By pressing the locking knob in the
middle of the wheel axle with your thumb, the
wheels can then easily be removed.
When attaching the running wheels the
locking knob also has to be pressed. Special
attention should be paid here to ensure that
the knob springs out again after attaching the
wheel as otherwise it is not secured. You will
know that if you can see the index groove.
Figure 48: Quick release axle with index groove
Before using the product, check if the
running wheels are secured and that the quick
release axles are locked.
21.2 Checking and setting the wheel
tracking
Well adjusted wheel tracking significantly
improves the easy running characteristics of
the product. To check the tracking, proceed as
follows:
Position the product on a flat surface and apply
the parking brake.
Measure the axle heights (from the ground to
the drive running wheel axle) and write this
dimension onto both tyres at front and back (on
the tread of the tyre).

Figure 49: Drawing the axle height on the front and
back of both tyres of the running wheels
Afterwards measure the distance between the
running wheels front and back at the height of
the axles along the markers. Ideally, the
distance between both running wheels should
be the same size at the front and back. In
general, it can be said that the distance
between the running wheels at the front and
back may not be larger 5 mm. If this is not the
case, the wheel tracking needs to be
corrected.
Figure 50: Distance between the markers on the
tyres (at axle height), back
To adjust the track proceed as follows:
1. Loosen the aluminium locking nuts on bo th
sides (AF 41 mm).
Figure 51: Drive wheel bushing and aluminium,
locking nut, product view from behind
2. Correctly adjust the track by turning the
drive wheel bushing (AF 24 mm). Here it
can be said that: If you turn the drive wheel
bushing in the direction of travel, the track
at the front will become more narrow.
When turning against the direction of
travel, the behaviour is exactly the
opposite.
3. Make sure that the distance at the front to
the frame on the right and left is the same.

4. Check by measuring the distance between
the running wheels at the front and back
again at the axle height (along the
markers) so that the distance between the
running wheels at the front than at the
back is no more than 5 mm.
Figure 53: Distance between the markers on the
tyres (at axle height), back
5. If all the distances are correct, then use an
open-ended spanner (AF 24 mm) to hold
the running wheel bushing in position and
tighten the aluminium locking nut (AF 41
mm) with a tightening torque of 70 Nm.
22 Adaptation and decoupling the
drive unit
22.1 Safety instructions
The drive unit may only be adapted and

There is some maintenance work or checks
which should be carried out by the user
themselves at regular intervals (approximately
every 4 weeks depending on the frequency of
use):
The chain should be cleaned and
lubricated with chain oil (observe the
manufacturer's instructions).
Check the tyres for damage, foreign bodies
and any cracks that form.
Check the function and ease of running of
the quick release axles on the running
wheels.
Check the cable housings are seated
correctly and tightly in the gear cable
holders.
Cables and lines should be checked for
kinks and crushing.
Check the brake pads.
Check the tyre pressure and correct if
needed (the tyre pressure should always
be as printed on the tyre covers).
If you should discover any problems
during these checks, please immediately
contact your dealer or PRO ACTIV. Service
and repair work on the product may only be
carried out by your dealer or PRO ACTIV.
Operating instructions NJ1 & FREAK Compact bike
31
In addition to these maintenance tasks /
checks by the user, PRO ACTIV has
prescribed maintenance tasks to be carried
out by the dealer or PRO ACTIV for safe
operation of the product and to minimise the
risk to the user or third-parties.
The initial inspection is performed after running
200 kilometres or 5 months after delivery
(whichever comes first). The maintenance
schedule can be found in the inspection lists in
chapter 36.
Subsequent inspections are then always
performed after 1,000 kilometres running or
after a period of 1 year (whichever comes first).
The maintenance schedule can be found in the
inspection lists in chapter 36.
After extreme loads, e.g. during holidays where
the product was used on sand, near sea water
or in snow, it is recommended that an
additional deep clean and inspection is
performed by your dealer or PRO ACTIV.
To maintain the operating licence and the
warranty validity, the performance of the
maintenance tasks must be documented. Any
faults identified during maintenance work must
be rectified and documented as such before
further use of the product.
Even if your product does not show any signs
of wear, damage or malfunctions, the regular
safety-related checks on your product must be
carried out in accordance with the
maintenance schedule.
27.3 Proof of maintenance
To provide proof of the maintenance, you can
use the inspection lists in chapter 36. The
inspection lists are also available as pdf files
which can be filled in within the download area
of www.proactiv-gmbh.com
under the link
"more documents >>". In any event, keep all
documents / service reports as a means of
proof, and get any service work which was not
carried out by PRO ACTIV documented.
Please bring these operating instructions /
service booklet to every service.
28 Disposal & Recycling
At the end of the service life, the product can
be disposed of by PRO ACTIV or your dealer
in a proper, environmentally-friendly manner.
The disposal or recycling must be carried out
by a waste disposal company or a municipal
waste disposal centre.
Special guidelines may apply on-location with
regard to the disposal or recycling. These must
be clarified and considered when disposing
(this may also include the cleaning or
disinfection of the product before the disposal).
In the following section, you will find a
description of the materials for the disposal
and recycling of the product and its packaging:
Aluminium: frame, rims, leg rest, tube plugs
Steel: fixing points, quick-release / screwed
axle, screws, nuts
Plastic: handles, quick release lever, tube
plugs, tyres, bags for packing
Synthetic fibres and foam: padding, covers
Cardboard / paper: packaging
29 Re-use
If your product has been provided to you by
your funding provider and you no longer
require it, you should report this fact to your
health insurance company or your dealer and
follow the instructions provided by them. Your
product can then be simply and economically
re-used.
Before any re-use, a safety check must be
carried out on the product by PRO ACTIV.
In addition to the instructions contained in
chapter 26 (Cleaning and care), a thorough
cleaning of the grips and all controls must be
carried out.
Before the product can be reused, it must be
prepared with care. A disinfection agent must
be sprayed onto all surfaces that the user may
make contact with. For this purpose, a liquid
disinfection agent based on alcohol must be
used for the quick residue-free disinfection
Operating instructions NJ1 & FREAK Compact bike
32
(e.g., Exporit 4712). Please observe the
manufacturers instructions for use for the
disinfection agent that you use. In general, a
complete disinfection cannot be guaranteed on
the seams. We therefore recommend that you
dispose of the seat and rear padding.
This will also be done by PRO ACTIV as part
of the safety check. The safety-related check
must be initiated by the funding provider.
Moreover, in event of wear or due to
adaptation to the user groups, such as the seat
and back system, you can adapt or change
using the modular system.
30 Warranty
PRO ACTIV guarantees that the product was
free of any defects at the time it was handed
over. This warranty expires 24 months after the
