3. 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 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.

6. INTENDED USE
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.
The manufacturer is not liable when the three-wheeler is
used in areas other than those for which it is designed.

8. PRODUCT DESCRIPTION
8.1 The frame
The Huka Cratos 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.
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
The Cratos 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) making it easy to steer around turns (see fig. 2).
Figuur 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.
