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.

limited natural body movement.

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.
