2. INTRODUCTION
Cycling is intended as an enjoyable activity. The fact that millions of people cycle their
bikes every day with pleasure appears to bear out this fact. The bicycle is more than
just a means of transport. It signifies freedom and a sende of adventure. Bicycles are
kind to our environment; they give us that “green feeling”. However, not everyone is
able to enjoy the pleasures of a common two-wheeler. Huka has added a series of
three-wheelers to its range so that everyone can experience all the pleasurable
aspects of cycling. Things like ergonomics, measurements, quality and look have
played a very important part in their design.
Your Huka Orthros duo-cycle is a quality product. Each and every component of your
Huka three-wheeler has been rigorously tested. The frame and its added features are
all made to the highest standards. This guarantees you both an excellent product and
carefree enjoyment. When you receive delivery of your Huka three-wheeler, all of the
parts will already have been fine-tuned according to your specifications. However
modern it might be though, even an Huka three-wheeler is not maintenance-free.
Sometimes there will be things that demand your attention. This manual contains
instructions on the kind of maintenance you can carry out yourself and information
about what your Huka dealer can do. Being able to carry out some of the maintenance
yourself only adds to your level of enjoyment!
Pay special attention to bold texts written in italics and to
wherever you see this symbol.
The texts in the green bars are supplementary information and
demand extra attention. Make sure you read these carefully.

7. PRODUCT DESCRIPTION
7.1 The frame
The Orthros duo cycles are made of high-quality materials. The frame consists of a
metal tube Construction with aluminum and steel parts. Most of the metals used are
provided with an impact resistant coating.
Together, the construction and finishing guarantee many years of enjoyment..
7.2 Mudguards
The mudguards are made of impact resistant plastic and are fully coated. They
prevent water from splashing up onto one’s clothes.
7.3 Drive mechanism
The duo cycle is equipped wit hits own specially designed drive mechanism for the
rear wheels. This mechanism prevents the bike from veering off to one side (by
means of a differential) making it easy to steer around turns (see fig. 2).
Fig. 2: Rear-wheel drive mechanism
With the differential mechanism, each Wheel is driven independently of the other.
This ensures that the bike continues in a straight line (image on the right) and that
turns are easier to make.

11
7.4 Wheels and tyres
The wheels have high-quality hubs, stainless steel spokes and aluminum rims. Topquality tyres are fitted to the rims. These ensure good grip and minimal rolling
resistance and wear and tear.
7.5 Spokes
The spokes keep the wheels stable on the duo cycle. That’s why the right tension is
so important. As spokes need some time to adjust and settle, the wheels should be
checked after the First few weeks of use. Your Huka dealer will adjust the spokes to
the right tension. Should a spoke become loose or break, your Huka dealer can fix
this for you.
7.6 Brakes (depending on model)
The Orthros duo cycle comes equipped with a drum brake in the front wheel and two
disk brakes on the rear wheels. The non-handicapped user can activate the brakes
by hand levers. I fit is the case that an electromotor has been fitted, then a rim-brake
will have been fitted in the front wheel.
Tyre pressure and wear and tear of the tyres have a
considerable effect on the behavior of your bike. Check your
tyres regularly in order to ensure safety.
Brakes are extremely important when it comes to safe
cycling. They can suffer from wear and tear over time. Have
your brakes checked and adjusted regularly, and changed if
necessary. This should only be done by an official Huka
dealer.
Spoke tension has a considerable effect on the behavior of
your bike. Check the spoke tension regularly in order to
ensure safety.
12
7.7 Parking brake
The Orthros duo cycle is equipped with a parking brake. This brake ensures that the
bike cannot roll away when you are mounting or dismounting. Therefore, you should
ensure that you have activated this brake before getting on or off the bike.
You can activate the brake by pushing the handle fully forward. This applies the
brake to the front wheel so that your bike is safely parked.
7.8 Chain guard
The chain guards have been specially designed for these duo cycles and are made
of impact resistant coated plastics. It prevents the chain from getting dirty and wet,
and also ensures that the chains do not dirty your clothes.
7.9 Crankshaft, crank set and pedals
The bottom brackets used by Huka are completely maintenance-free and nonadjustable. Should you encounter any problems then contact your Huka dealer. If you
should notice any play between the crank and crank shaft, then you can remove the
dust-cap and tighten the nut with a suitable wrench. The pedals are also usually
maintenance-free. If you should notice any play, contact your Huka dealer. When
fitting the pedals yourself, don’t forget to read the instructions for the L (left) and R
(right) pedals. The left pedal is attached by turning anti-clockwise, the right clockwise.
Use a spanner or a (small) pedal wrench. There are also other (adjusted) pedals
available. See our brochure.
Always use the parking brake when mounting and
dismounting. This will prevent the bike from rolling away. You
run the risk of falling if the bike moves away from you.
13
7.10 The chain
When your chain has been tightened properly, your three wheeler will be easy to
pedal and you won’t hear any noise from the chains. Your chains will already have
been tightened properly by your Huka dealer before your bike is delivered. If you find
that a chain is too loose, then get your Huka dealer to fix this. Both the chains and
the drive mechanisms are protected by a plastic chain guard.
7.11 Gears (optional)
Gears make cycling easier. They allow cyclists to cycle without having to exert too
much effort, and in all kinds of weather. This cuts out the hard labour. The bike
comes standard with a 8 gear, combined, if you wish, with a back-pedal brake or a
coaster brake (reverse pedaling also possible).
Adjusting the gears
If you have chosen for a three-wheeler with gears, then there will be an extra hub
between the pedals and the drive shaft. This is standard a 8 gear of Shimano, type
Nexus, which has been adjusted for use on the Huka three-wheeler. Your Huka
dealer will have checked and adjusted the gears before delivery of your bike.
A manual explaining the workings of the relevant gear system will be supplied along
with your three-wheeler. Contact your dealer is you have any problems.
7.12 Seats
The Seats provide comfort and stability when cycling. The Seats are adjustable in
back and forward directions and can be rotated for easy access. It is very important
that the seats are adjusted properly so that you can cycle efficiently, comfortable and
safely.
Make sure that the Seats always are locked properly. A not
locked seat can be very dangerous. Check on regular basis
whether the seat is still locked by the locking mechanism.
Tightening the chains requires special skills and should be left
to your dealer.
Adjusting the gear hub requires special skills. This should
only be done by an authorized Huka dealer.
14
7.13 Handlebars (depending on type and make)
The handlebars are made out of either steel or aluminum, depending on the bike and
the type of handlebars. The handlebars can be adjusted for height. For some models
also the angle and depth is adjustable.
The main driver steers the bike, the steering of the passenger is a fixed type.
7.14 Lights (depending on country)
The Orthros duo cycle comes with LED powered lights. The lights are very reliable
and energy efficient. They use AA batteries, which are widely available and
inexpensive. LEDs use a comparatively low amount of energy and are long lasting.
The batteries can be changed easily.
7.15 Luggage carrier
The Orthros duo cycle standard comes with a luggage basket. This basket is
mounted with four bolts with following specifications:
Bolts: Button head screw with hexagon M6x10; minimum class 8.8
Make sure that the handlebars are firmly attached. Loose fitted
handlebars can be very dangerous. Check your handlebars
regularly.
Make sure that you change the batteries before they run
down, otherwise the lights will stop working. This can be very
dangerous if that happens when you are cycling at night.
Make sure that the right parts are used fo mounting the
luggage basket and that these are regurarly checked for
tight.
The loading of the basket must be equally spread left and
right in order to influence the driving characteristics as
little as possible.
The maximum load of the luggage basket is 10 kgs. The
total maximum load for the Orthros is 120 kg driver+120
kg passenger + 10 kg luggage=250 kg.
15
7.16 Electric motor (optional)
The Orthros duo cycle can be fitted with an electric motor. This motor is attached to
the front wheel. The battery pack and electronics are mounted on the main frame
tube, with a users control and display on the steering of the main driver.
Controls on the steering Display op the steering
Changing the luggage basket will influence its safelty and
is not allowed.
The luggage basket is not suitable for attaching a child
seat or a trailer.
Whenever the luggage basket is loaded, this can influence
the driving characteristics. It is advised to experience this
in a safe area.
When mounting specific luggage in or on the luggage
basket, the instructions of that supplier must be followed.
Pay special attention to loose straps that can ge tinto the
spinning wheels.
Light and retro reflectors are mounted aside the luggage
carrier. Make sure that no luggage is blocking the free
view on these lights and reflectors.

be viewed on the display.
The bike is provided with a 36V 11Ah Li-ion battery that is mounted on the main tube
of the frame.
7.17 Accessories
There are a number of accessories available for the Orthros. For example, armrests,
a footrest, etc. (see our special brochures).
17
8. SET-UP
8.1 The seat depth
Correct adjustment of the seat will make it almost comfortable as a good chair and
enable you to cycle long distances with ease. There is a useful rule-of –thumb for
adjusting the seat properly. Remove your shoes and sit on the bike with the pedal
crank extended straight from you. With your heel on the pedal, you should just be
able to stretch your leg fully. This is the ideal “working distance” for when cycling with
the ball of your foot (with shoe) on the pedal. You can make slight adjustments to the
saddle distance in order to find the one most comfortable distance for you.
1. Pull the lever under the seat to unlock the seat.
2. Slide the seat to the requested position.
3. Release the lever and move slightly back and forward in order to allow the locking
mechanism to fall into the slot. This can both be heard and felt.
8.1.1 Turning the seat
You can turn the seat to make it easier to get in en out.
1. Put the seat in the front position. See 8.1 seat depth
2. Pull the hendle up to rotate the seat.
3. Turn the seat in the right position.
4. Turn the seat back and move the seat a bit till you hear that the seat
Make sure that you lock the seat properly again. A loosefitting seat may slip when you are cycling. This can be
dangerous.

2. Pull or push the handlebars to the desired angle.
3. Tighten the handlebars bolt again.
Sometimes the handlebars may be stuck very tightly and
can’t be moved even when you loosen the bolt. If that is the
case, use a plastic or rubber hammer to loosen the bolt. When
you strike it, it will slip down slightly and the handlebar will
become loose.
Make sure that enough length of the handlebar stem is still in
the main frame. The safety marking on the stem must
therefore remain inside the main frame.

22
8.3 The wheels
The Wheel is the most important part of the bike with regard to troublefree cycling
and comfort. A number of features are important, including well pumped tyres, tightly
fixed spokes and supple, play-free movement.
8.4 Tyre pressure
For most tyres, the pressure is correct when you can squeeze the tyre a little using
your thumb and finger. If your tyres are too soft then they will wear out quicker, while
cycling on hard tyres is much more comfortable and ensures that your three-wheeler
reacts better to braking and steering. The inner tubes on the three-wheeler are fitted
with a “normal” valve. You can pump up your tyres yourself.
Before using your bike, check that the wheels are turning
freely and not squeaking. Squeaking noises are often an
indication of loose spokes or faulty bearings. If you should
notice this then contact your dealer.
23
9. USE
9.1 Using for the First time
When using your Orthros duo cycle for the First time, find yourself a large,
unoccupied area where you can try it out.
9.2 Mounting
Activate the parking brake before mounting. This makes mounting the bike easier
and safer. Some models have a step on the frame.
The seat can be turned outward for easy accessibility. Lever hereto the handle
under the seat. Make sure that you hear and feel the locking mechanism falling
into the slot. Eventually move the seat back and forward a little.
9.3 Cycling
Release the parking brake and start pedaling slowly. The bike will start moving. If you
have a bike with gears, make sure it is in First gear. This makes it easier to start
pedaling.
9.4 Steering
At first, steering a three-wheeler might seem a little different to steering an ordinary
bike. The three-wheeler tends not to lean naturally into a turn. Use your arms, and
not your body, to steer. For sharp turns, lean your body slightly into the turn. This will
keep both you and your bike stable.
Reduce speed when turning. Especially on Sharp turns.
Turning too fast will reduce your stability. This can lead to
physical and/or material damage.
Avoid sudden and exaggerated turning movements. These will
destabilize you and your bike. This can lead to physical and/or
material damage.
Recommendations for safe cycling:
Use a safety helmet.
Check before using the condition and functioning of
brakes, tyres, rims and steering.
Braking distance can be longer under wet weather
conditions.
Inform yourself about relevant regulations for the use of the
bike on public roads.
24
9.5 Changing gears (optional).
If your bike is fitted with gears, you can use them to adjust speed. To change gear,
first stop pedaling. Then turn the gearshift to select the desired gear.
The selected gear will be displayed on the gearshift. Once you have chosen the
desired gear, you can start pedaling again.
9.6 Brakes (depending on model)
Do not pedal while changing gears. This can damage the gear
mechanism. Damage to the gear hub resulting from misuse is
not covered under the warranty.
Certain materials can get excesive hot by exposure to direct
sunlight
A duo cycle has moving parts. Be aware of pinching .
Be alert on interferance between electronic equipment and
your bike when your electric motor system is on..
The left brake lever is used for activating the rear brakes. The
right brake lever is used for activating the front brake..
25
There are several options for braking.
The brakes are activated by the main driver. The passenger has no brakes.
Back-pedal brake
The back-pedal brake is activated by pedaling backwards instead of forwards. This
works on both rear wheels via the intermediate shaft. This brake is optional available.
Handbrakes
You can brake a duo cycle with handbrakes by squeezing both levers on the
handlebars. This activates the brakes on both the front and rear wheels. The right
hand lever activates the brake on the front Wheel, the one on the left those on the
rear wheels. It is best to use the left-hand brake when turning. Practice using the
brakes in a large, enclosed area before taking your bike out on the road. In this way
you can get used into using them.
Some models are fitted with both a back-pedal brake and handbrakes. In that case
you can use both if you wish.
9.7 Cycling with motor (optional)
If your three-wheeler is fitted with a motor, then follow these instructions.
A pedal sensor registers when you start to pedal. This then activates the electric
motor, which makes pedaling easier. The motor will stop as soon as you stop
pedaling.
9.8 Setting the electric motor assistance.
By pushing the arrow-buttons on the control unit, the level of electric motor
assistance can be set. The display will show the setting accordingly.
Be careful when using the front brakes while turning as this
can destabilize the bike. This can lead to physical and/or
material damage.
The braking characteristics of the three-wheeler change on
surfaces that are slippery, wet or uneven. Adjust your use of
the brakes accordingly.
26
Arrow-buttons
9.9 Cycling with motor using kick-start (optional)
The kick-start option is meant for easy start from standstill. By holding the “arrow-up
button” the motor is activated and brings the cycle to a speed of 6 km/h. Releasing
the button will stop the motor (when there is still no pedal movement).
Bedieningstoetsen
The motor assistance is activated or de-activated by pressing the “mode button”
three seconds.
27
Battery indicator
You can find the battery indicator on the display. It indicates the current level of the
battery. When all the blocks are black, the battery is fully charged. The blocks will
show empty when there is less battery power left.
It is also possible to use the indicator on the battery.
Push the button and the indicator gives the amount of energy.
By 5 led’s the battery is full, By 1 led the battery is almost empty.
Battery pack Battery indicator
Battery indicator
Check to see if the battery is full before setting out a long trip
so that you won’t be left stranded halfway.
The battery charger fits into a pocket on the battery pack. Take
it with you so that you can always charge up if required.
28
9.10 Moving and lifting the Orthros
To move or lift the bike you can grab at the back of the black connecting rods and the
front of the head tubes. We recommend to lift the bike with at least three people and
also to hold the front wheel and steering to prevent it from turning and causing
injuries.
29
10. MAINTENANCE
10.1 User maintenance
In order to be able to enjoy your Orthros for a long period of time, it is important that
maintenance be carried out regularly.
First maintenance check
After the first 200 kilometres, o rafter using the bike for two months, you should have
it checked by your Huka dealer. Every bike needs some time to “kick in”. During this
first check your dealer will check the nuts and bolts, the chain, spokes etc..
Cleaning
Clean the bike regularly. You can do this using warm water and a non-abrasive
cleansing agent. Special cleansing agents are available at most bicycle stores.
The rims can be cleaned using warm water and-or a soft haired brush.
Tyre pressure
Check the tyre pressure once a week. The correct tyre pressure ensures a smooth
and reliable ride. The tyres have normal valves, which means that you can use any
bicycle pump to inflate them.
The correct tyre pressure is 5 bar.
After pumping your tyres, always check the valves to make sure they are not leaking.
To do this, rub some saliva on the valve. If you see bubbles then the valve is leaking
and needs to be replaced.
Do not use a power hose or steam cleaner to clean your bike
as they will remove the grease from the bearings etc..
Never use a wire brush to clean the rims as this will damage
them.
Make sure that the tyre pressure is and remains correct. Not
enough tyre pressure will result in more resistance and
steering difficulties when cycling.
The first check should always be carried out by an authorised
Huka dealer. Checks carried out by unauthorised personnel
can affect the warranty.
30
Tyre tread
Controleer eens per maand het profiel van de banden. Deze moet voldoende zijn om
goede wegligging te kunnen garanderen. Check the tyre tread of your tyres once a
week. They should be in such a condition as to guarantee proper grip. If the tread is
less than 1 mm deep then the tyres need replacing.
Spokes and rims
The tension of the spokes needs to be checked every month. A squeaking noise is
usually a sign that a spoke is loose. A loose spoke can cause the rim to buckle,
which affects the behaviour of the bike. You can check the spokes by stroking them
like you would the strings of a guitar. A spoke that sounds off is probably loose.
Inform your Huka dealer of this.
.
The rims are made of stainless steel and require no maintenance except regularly
cleansing. Because there is no rim brake used, the rims do not suffer from
mechanical wear.
Chains
The chains should be cleaned and oiled once a month. There are special cleansing

Gears
The gears are a delicate and complex mechanical system. Contact your Huka dealer
if you have any trouble with the gears. He will have the required know-how and
equipment to adjust them for you.
Brakes
The brakes are extremely important and need to be tested regularly. Check them at
least once a week. A loosely fitted brake will not provide enough braking power. The
brakes can be tightened using the nut on the brake lever.
In order to tighten the brakes, turn the adjusting nut outward. Lock it into position by
twisting the lock nut.
Lights
The Orthros duo cycle comes equipped with battery-operated LED lights. The
batteries should last a very long time as LED lights use very little energy. They will
eventually run out, however, and will then need to be replaced. The batteries used
are of the AA type and can be bought in almost any convenience or hardware store.

If, after adjusting, the brakes still do not function properly,
have them checked, adjusted and in some cases replaced by
