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.

7.4 Wheels and tyres
The wheels have high-quality hubs, stainless steel spokes and aluminum rims. Top-
quality 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 non-
adjustable. 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.

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.

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
