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 sense of adventure. Bicycles are
kind to our environment; they give us that “green feeling”. However, not everyone is
able to enjoy the pleasures of the 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 three-wheeler 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 a 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.

General guidelines
The Huka three-wheeler has been specially designed for people with a physical
and/or mental disability. Cyclists who have developed a fear of falling as a result of
old age find the Huka three-wheeler to be an excellent alternative when they want to
be able to continue cycling carefree and comfortably. The Huka three-wheelers are
also used by people who suffer from neuromuscular disorders (such as cerebral
palsy, muscular dystrophy and spasms). This also applies to problems with
coordination of movement, balance and limited natural body movement.
Area of intended use
The three-wheeler has been designed for use on standard public roads and bicycle
paths. These are usually paved, level and solid. The three-wheeler conforms to all
regulations in relation to use on public roads.
Use of the three-wheeler as a racer or cross-country bicycle is not included in the
above.
6. INTENDED USE
The manufacturer is not liable when the three-wheeler is
used in areas other than those for which it is designed.

pay attention to the following before you go cycling:
- Make sure your bike is in perfect condition before using it.
- Check the pressure and the condition of the tyres.
- Check the brakes.
- Check your lights.
- Check that the saddle is securely fastened.
- Check that the handlebars aresecurely fastened.

- If you are taking luggage with you, make sure it is securely attached and cannot
fall off while you are cycling.
- Always cycle on level and solid ground.
- Avoid potholes, high ramps and puddles.
- Do not bump against the kerb and do not cycle too fast off the kerb.
- Reduce your speed when cycling on wet and slippy surfaces.
- Reduce speed when cycling down hills or off exits.
- Use the parking brake when mounting/dismounting.
- Always lock your bike when not in use.
Use of bike by children:
- Never allow small children use the bike on public roads.

Components
8.1 The frame
The Huka three-wheelers are made of high-quality materials. The frame consists of a
metal tube construction with aluminium and stainless steel parts. Most of the metals
used are electrolytically galvanized and provided with an impact resistant coating.
Together, the construction and finishing guarantee many years of enjoyment.
8.2 Mudguards
The mudguards are made of impact resistant plastic and are fully coated. They
prevent water from splashing up onto one’s clothes.
8.3 Drive mechanism (optional outside NL)
The three-wheeler is equipped with its 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 wheel) making it easy to steer around turns (see fig. 2).
Fig. 2: Rear-wheel drive mechanism
With the differential wheel, each wheel is driven independently of the other.
This ensures that the bike continues in a straight line (image on right) and that turns
are easier to make.

8.4 Wheels and tyres
The wheels have high-quality hubs, stainless steel spokes and an aluminium rim.
Top-quality tyres are fitted to the rims. These ensure good grip and minimal rolling
and wear and tear.
8.5 Spokes
The spokes keep the wheels stable on the three-wheeler. That’s why the right tension
is so important. As spokes need some time to adjust and settle, the wheels on your
three-wheeler 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.
8.6 Brakes (depending on model)
The basic model of this Huka three-wheeler comes equipped with a back-pedal
brake. This brake works on both rear wheels. You can also choose the option of
having handbrakes. These work on both the front and rear wheels. In this case, the
bike is fitted with so-called “rollerbrakes”, a perfect braking system that is easy to
use, will not jam, and that requires very little maintenance. If it is the case that an
electromotor has been fitted, then a rim-brake will also have been fitted.
Tyre pressure and wear and tear of the tyres have a
considerable effect on the behaviour 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.
Tyre pressure and wear and tear of the tyres have a
considerable effect on the behaviour of your bike. Check
your tyres regularly in order to ensure safety.

8.7 Parking brake
Unlike ordinary bicycles, the Huka three-wheeler 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.
8.8 Chain guard
The chain guard has been specially designed for this three-wheeler and is made of
impact resistant coated plastic. It prevents the chain from getting dirty and wet, and
also ensures that the chain does not dirty your clothes.
8.9 Crankshaft, crankset en pedals
The bottom brackets used by Huka are completely maintenance-free and non-
adjustable. Should you encounter any problems then contact your Huka dealer. If you
should notice any play between the crank and crankshaft, then you can remove the
dust-cap and tighten the nut with a 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.

12
8.10 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 chain. Your chain will already have
been tightened properly by your Huka dealer before your three-wheeler is delivered.
If you find that the chain is too loose, then get your Huka dealer to fix it. Both the
chain and the drive mechanism are protected by a plastic chain guard.
8.11 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 all the hard labour. You can
choose between 3 or 5 gears, combined, if you wish, with a back-pedal brake or a
coaster brake (reverse pedalling 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 a standard SRAM gear hub, 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 if you have any problems.
8.12 Saddle (depending on type and make)
The saddle provides comfort and stability when cycling. Saddles can be adjusted
according to height, depth and angle. It is very important that the saddle be adjusted
properly so that you can cycle efficiently, comfortably and safely. The type and size of
saddle are optional.
Make sure that the saddle is firmly attached. A loose-
fitting saddle can be very dangerous. Check your saddle
regularly.
Tightening the chain requires special skills and should be left
to your dealer.
Adjusting the gear hub requires special skills. This should
only be done by an authorised Huka dealer.

13
8.13 Handlebars (depending on type and make)
The handlebars are made out of either steel or aluminium, depending on the bike and
the type of handlebars. The handlebars can be adjusted for height, depth and angle.
8.14 Lights (depending on country)
The Huka three-wheeler comes with LED battery-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.
8.15 Luggage carrier
The luggage carrier is made of either steel or aluminium, depending on the make of
the bike. Its design allows the attachment of standard saddlebags and kids seats.
You can also choose to have carrier straps added. Ask your huka dealer to help you
with this. If your bike has an electric motor then the batteries will be attached under
the luggage carrier.
Some models have a luggage carrier at the front of the bike where you can usually
attach a plastic or wicker crate/basket.
Make sure that the handlebars are firmly attached. Loose-
fitting handlebars can be very dangerous. Check your
handlebars regularly.
Make sure 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
on poorly-lit roads.
The maximum weight for the luggage carrier is 25 kg. For
luggage carriers on the front of the bike the maximum is
15 kg.

14
8.16 Electric motor (optional)
The Huka three-wheeler can be fitted with an electric motor. This is attached to the
front wheel and comes with a battery pack attached to the luggage carrier, a small
holder for the electrical components under the frame, and a throttle on the
handlebars.
throttle
holder for electronics battery pack in saddlebag
Pas Vario system
When using the Pas Vario system, one’s pedalling is assisted by the electric motor in
the front wheel.
Auto Vario system
This is a type of electrically powered bicycle. The bike is propelled by engaging the
throttle. There is no need for you to pedal yourself.
There are two types of battery pack available for both these systems - a 36 volt, 6.4
Ah pack and a larger 36 volt, 9.6 Ah pack.

15
8.17 Accessories
There are a number of accessories available for the Huka three-wheeler. For
example, extra saddle support, footrest, pushing frames, bags etc. (see our special
brochures). The colours of the accessories are made to match the colour of the bike.

16
The Huka three-wheeler is designed in such a way that the user can choose different
sitting positions on the bike by adjusting the handlebars and saddle. These vary from
energetic to comfortable.
9.1 The saddle height
Correct adjustment of the saddle will make it almost as comfortable as a good chair
and enable you to cycle long distances with ease. There is a useful rule-of-thumb for
adjusting the saddle height correctly. Remove your shoes and sit on the bike with the
pedal crank extended straight down. With your heel on the pedal, you should just be
able to stretch your leg fully. This is the ideal “working height” for when cycling with
the ball of your foot (with shoe) on the pedal. You can then make slight adjustments
to the saddle height in order to find the one most comfortable for you.
adjusting saddle height
1) Use an Allen key, size 5, to loosen the saddle bolt.
2) Pull or push the saddle to the desired height.
3) Tighten the bolt for the saddle pipe again.
comfortable
energetic
Make sure that the saddle pipe is inserted at least 6 cm into
the frame. You should not be able to see the safety mark on
the saddle pen.

can move the saddle.
2) Pull or push the saddle into the desired position.
3) Tighten the saddle bolt again.
9.3 The saddle angle
1) Use a size 13 spanner to loosen the saddle bolt, just enough so that you
can turn the saddle.
2) Pull or push the saddle to the desired angle.
3) Tighten the saddle bolt again.
Make sure that you tighten the saddle properly again. A loose-
fitting saddle may slip while you are cycling. This can be
dangerous.
