1. INTRODUCTION

Cycling should be a pleasant activity. That is clear. Every day millions of Dutchmen mount
their bicycles with pleasure. The bicycle is more than just of mean of transport. Cycling
radiates freedom and adventure. By means of cycling we save our environment, we obtain
somewhat more of the green feeling.
But not everybody can make use of the ordinary bicycle. Huka has developed a series of
tricycles in order that everybody can enjoy all pleasant aspects of cycling. Aspects like
ergonomics, sizes, quality and styling have all played an important role in the design.

In general

Your Huka tricycle is a quality product. Every component of your Huka tricycle has been
tested and checked extensively. The finishing of the frame and the mounted components are
of high quality. There for you are assured of an excellent product a careless cycle pleasure.
When supplying your new Huka tricycle, in principle all described components are adjusted
well and / or are turned to you wishes. But no matter how modern, even a Huka tricycle is
not completely free of maintenance. There are some things that require attention from time
to time. This small manual provides instructions for maintenance that you possible can do
yourself and provides information about activities of your (Huka) dealer. To do a little
maintenance can be quite fun, because it contributes to a greater cycle pleasure.

2. PRODUCT DESCRIPTION

2.1 Purpose of use

The Huka-tricycle is a cycle for handicapped children and adults. The range of sizes of the
Huka-AT tricycles includes a great overlapping area of successive sizes (see figure 1). In this
way it is easier to choose a cycle with the right size for the user, which can be used for a
maximum length of time in the case of growing children.

2.2 Safety and driving behaviour
Before you take delivery of your new ready-to-drive tricycle your dealer will have checked all
components himself and, if necessary,
will have adjusted these in order that you can cycle. If it is the
first time that you are sitting on a tricycle this will be somewhat uneasy.

2

No matter how sporty your tricycle is, never get tempted into
too much enthusiastic behaviour on the roadway or riding on
and off pavements. Your tricycle can sustain visible or invisible
damage, which involves additional risks.

In order to use your tricycle safely we advise you to (let) replace
worn components like inner tubes, outer tubes, and brake block immediately. These
components are obtained from every cycle shop or from your dealer.

tricycle without differential Huka tricycle , with differential

Figure 2: Drive of rear wheels

Both wheels are driven independently from each other by the differential. Therefore the tricycle
rides straight-ahead
(right-hand picture) and bends can be taken more easily.

2.3 Prevention of theft
A safety lock is mounted on most versions of the tricycle. If you want additional measures
against theft than and additional cable lock is convenient to anchor you tricycle rock-solid.
These locks are available in many cycle shops

2.4 Gear and driving

The tricycle is equipped with an own designed, specially made to size drive of the rear
wheels. This drive (by means of a differential) take care that the tricycle does not pull
obliquely and bends can be taken easily (see figure 2).

2.5 Accessories

A series of accessories can be supplied for the range of the Huka-tricycles. The possibilities
are listed in the overview.
Almost all accessories can be provided for each type of tricycle.
Ask your dealer if the respective accessory can also be supplied for your type of tricycle.
The accessories have colours matching the colours of the tricycle; thus the accessories and
the tricycle form a unit.

3

Always lock your tricycle, also when you leave it just for a short
moment.

3. COMMISSIONING

The HUKA-tricycles are designed in such a flexible manner that
the user can choose between various positions of the body on the
bike because of the adjustment possibilities of the handlebars and saddle, which varies from a
sporty to a comfortable posture.

c

omfortable sportive

3.1 The height of the saddle
When the saddle is in the right position you are sitting almost as comfortable as in a good chair
and effortless you pedal the
kilometres away.
There is a good rule of thumb for the correct height of the saddle.
You take a seat on the tricycle without your shoes on and with the crank pointing in the extended
direction of the seating tube.
When you have your heel on the pedal then you should just be able
to stretch your leg. Then you have during a turning pedalling movement, with the ball of your foot
(with shoe) on the pedal, the ideal working height. Start your try-out at this position, then after
some time you can adjust to you personal liking.

Figure 3: Adjusting the height of the saddle:

1) Unscrew the saddle pin bolt somewhat with an open-end or a ring spanner in order that the
saddle pin can move easily.

2) Now, pull or push the saddle to the position wanted by you. But take care that the pin stays in
the frame over a distance of at least 6 cm.

3) Now, retighten the saddle pin bolt.

The height of the saddle can be adjusted by unscrewing the saddle pin bolt a little bit and moving
the pin upwards or downwards (see figure 3).

4

Figure 4:
Adjusting the saddle forwards and backwards and tilting:

1) Unscrew both bolts of the saddle strap with an open-end or a ring spanner in order that
you can move the saddle.

2) Move or turn the saddle into the position wanted by you.

3) Now, retighten the bolts.

The adjusting forwards or backwards and also the tilting of the saddle can be made by
unscrewing both bolts of the saddle strap (see figure 4).

Figure 5: Adjusting the height of the handlebars

1) Unscrew the expansion bolt with an Allen key about 4 turns.

2) If necessary, tap the bolt downwards with a wooden or plastic hammer.

3) Adjust to the height that is suitable for you and retighten the bolt.

3.2 The position of the handlebars

The handlebars also play an important role for pleasant seating. You can also adjust your
handlebars in several manners. By putting the handlebar shaft lower of higher you can adjust
the position of your back and the pressure of your hands on the handlebars. You can adjust the
height by unscrewing the expansions bolt about 4 turns (see figure 5) and if necessary
tapping down the bolt with a wooden or plastic hammer. You can adjust the height when the
bolt is loose.

5

But make sure that the pin stays in the frame over a
distance of at least 6 cm. Thus the safety marking should
not be visible.

Figure 6: Adjusting the angel of the handlebars

1) Unscrew the clamping bolt in the front construction with an Allen key.

2) Take the handlebars at the handles and turn the handlebars to the desired position.

3) Retighten the bolt.

When you want to adjust the position of your hands on the handlebars, you can do it by
unscrewing the clamping bolt in the front construction and thereafter turning the curve of the
handlebars in the desired position (see figure 6).
Although Huka take great care in mounting the handles it is possible that they can loosen in
time because of the influence of sunlight, temperature variations or ageing. Therefore check
regularly that they are still tight by trying to turn the handles.

3.3 The wheels

The wheel is the most important component of the cycle, which is responsible for a light ride
and a high cycle comfort. Many matters
are important thereby, like well-inflated tyres, tightly tensioned
spokes and a light running with absence of play.

3.3.1 Pressure and valve

The correct tyre pressure is obtained for most tyres when you can still push the tyre in a little
bit. When your tyres are too soft they will wear down faster. You will ride much more
comfortable on quite hard tyres and your tricycle listens better to the brake and movements of
the handlebars. The inner tubes of the tricycle are equipped with a common bicycle valve.

6

However, make sure that the safety marking stays in the
frame tube over a height of about 6 cm.

3.3.2 Spokes

The spokes take care of the stability of the wheel and thus of the tricycle. Therefore a correct
pressure is important. Because new spokes always have to stabilise to some extent, the wheels
of your tricycle have to be checked after a couple of weeks. Then your Huka-dealer adjusts the
spokes tot the correct tension. In case it happens that a spoke breaks or is sitting loose then
your Huka- dealer will of course put this right.

3.3.3 Hubs

The hubs of the wheels should be adjusted accurately. Actually there should not be any
noticeable play. If you notice an excessive play or the wheel is running heavily then ask your
Huka-dealer to put this right.

3.4 The drive
The drive system takes care that your pedalling force is converted optimally into movement.
The system consists of many moving components: the chain, the gear (option), the crankshaft,
the crank and the pedals. Of these, many components are free of maintenance.

3.4.1 Crankshaft, crank and pedals

Most crankshaft bearings mounted by Huka are completely free of maintenance and cannot be
re-adjusted. If it does happen that play develops in the bearing then it is necessary to contact
you Huka- dealer immediately.
If play develops between the crank and the crankshafts then you can take off the dust cap and
retighten the underlying bolt with a socket spanner. Most pedals are also free of maintenance.
If the play is too large you can consult your Huka-dealer.
When you are mounting the pedals yourself watch for the indications L (left) and R (right on
the pedal axes. The left pedal is screwed in anti-clockwise, the right pedal clockwise. You can
use an open-end spanner or a special (narrow) pedal spanner. Specially adapted pedals can
also be provided as an option. See paragraph 2.5 Accessories for this purpose.

3.4.2 The chain

When the chain pressure is correct your tricycle pedals lightly and you will not hear the chain.
When your tricycle is delivered the chain will be well adjusted by your Huka-dealer. T
here are even two chains when your tricycle is provided with a gear. If you notice that one or
the other chain is too slack have it re-adjusted by your Huka- dealer.

3.4.3 Gear (option)

Gears are making things easier for the cyclist. The cyclist gas at his disposal an optimal gear
ratio for all weather conditions, with which it is possible to cycle in a pleasant manner without
having to exert much force. Therefore it is not necessary to labour and to stamp on the pedals.

3.4.3.1 Adjustment of the gear

If you have chosen a tricycle with gear there will be an additional hub between the pedals and
the drive axle. This is a standard gear hub from Sram, which is adapted for use on the Huka­tricycle. Your Huka-dealer has checked the gear on delivery and has adjusted it correctly. There
for, in case of any problems, it is best to consult your dealer.

8

This is very specialistic work that can be best left to your
dealer. A plastic chain cover protects both the chain and the
drive system.

4. USAGE

4.1 Instructions for use

If you want to ride the tricycle, then first lock the parking brake. This way is is easier to get
on the tricycle.
Before getting on the tricycle you can use the footplate, in front of the pedal.
After you are sitting comfortable, you can unlock the parking brake and start to cycle.
When you cycle for the first time, find a quiet and safe place, so you can get use to the
tricycle.

4.2 User environment

The Huka tricycles are suitable for use on roads with firm underground.
The tricycle can be used into all weather, but avoid when possible contact with salt water
because of the influence of the metal parts.

4.3 Familiar user errors

The following user errors are possible and should be avoided.

These errors can cause personal injuries or damage to the product.



Always provide for the correct pressure of the tires.



Avoid persons near the tricycle, particularly with the wheels, dangerous

situations can occur.



Check regularly the good functioning of the brakes and make sure the

function perfect.



Check regularly the good functioning of the lights and make sure the

function perfect.



Respect the traffic rules and regulations seriously and take caution in traffic.

Respect the following situations:

4.4 Brakes

4.4.1 Rollerbrakes

Your Huka-tricycle is equipped with a reliable brake system, which functions well if the brakes
have been adjusted in the correct manner. As is standard, your tricycle is equipped with
rollerbrakes. Rollerbrakes do not require much maintenance. The brake cable should be re­tensioned if the brake handles almost touch the handlebars. This can be accomplished with the
use of the adjustment screw near the siphon on the rollerbrakes (see figure 7). But of course you
can have this done by your dealer.

4.4.2 Parking brake

All tricycles are equipped with a parking brake. This brake takes care that the tricycle stays firmly
at its position when mounting or dismounting the tricycle. The operation of the parking brake
takes place by means of a lever that is present on the handlebar axle, closely underneath the
handlebars themselves. You put your tricycle on the parking brake by turning this lever upwards
as far as possible. To unlock the parking brake you can turn the lever downwards until the stop
(see figure 8).

10

Figure 7:
Tensioning of the drum brake cable

-

Turn the little screw a few times clockwise
if your brake lever (near the brakes)
touches the handle.

-

Then the cable will be tensioned.

When you notice that the brake is already
operating when you squeeze the lever only lightly
you can slacken the cable somewhat by turning
the little screw anti-clockwise.

Figure 8:
Operation of the parking brake.

- You can put the tricycle on the
parking brake by turning the
lever upwards as far as possible

-To unlock the parking brake, turn
the lever downward again until
the stop.

4.5 The lighting

Your tricycle is provided with a safe and reliable lighting. Always check that all lights are working
when you have the lighting on. It is highly dangerous when you ride in the dark, in the twilight or
in the mist without lights. Check the following points if (part of) your lighting does not function:

 Check that the electric wires are connected to both lights and the dynamo and there is no

formation of rust.
 follow the electric wires and check that the insulation layer of the wires is still intact everywhere
(check that there is no short circuit because of naked wires),

 check that the lights in their fittings are free of oxidation, that contact is made and that the

filaments are not broken,

 check that the dynamo is adjusted well and is running on the middle of the tyre.

check that the electric wires are not broken and / or are not jammed anywhere,

Figure 9: Turning grasp Gear shift

4.6 Operation of the gear

It is easy to operate the gear lever of the three (or five) gears hub. The gearshift has three (or

five) positions where in the lever clicks by itself. You can shift the gear to lighter or heavier

pedalling by simply moving the lever to the wanted position (see figure 9). Thereby, one is the

lightest position and three (or five) the heaviest.

4.7 Safety lock

If you want to lock your tricycle you should first turn the key clockwise and hold it before you can

push the handle downward.

If the lock is bolted the key jumps back and can be taken away.

4.8 Lifting

It is because of the weight, not possible to lift your tricycle alone.

Lifting with two persons is possible. Pay attention to lift the tricycle only at firmest parts and

not for example the accessories.

11

Attention:

keep the pedals motionless when changing gear!

5. MAINTENANCE

5.1 Cleaning

The metal parts, the plastic parts and the soft parts, like saddle, can be best cleaned with a soft,
moisten cloth.

Here you can use soap. Use never aggressive or scratching cleaning agents.
The different mechanisms should regularly controlled on impurities such as grain of sand etc. and
when necessary be clean-brushed

Cleaning regularly aids the preservation of your tricycle.

Never use a high-pressure sprayer for cleaning your cycle. This is because the
pressure of the water is so forceful that you will spray the grease from the bearings.

It is advisable to regularly lubricate or to grease all moving parts or to have this done by
somebody.

5.2 Protection against corrosion

Your Huka tricycle is well protected from corrosion.
It is sufficient enough to dry the tricycle, after it became wet. There are no necessary special
protecting measures.
