1. INTRODUCTION
Cycling should be a pleasant activity. That is clear. Every day millions of people 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 the Duet 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 Duet is a quality product. Every component of your Huka Duet has been tested
and checked extensively.
The finishing of the frame and the mounted components are of high quality. Therefore you
are assured of an excellent product that provides carefree cycling pleasure. When supplying
your new Huka Duet, in principle all described components are adjusted well and/or are
tuned to you wishes.
But no matter how modern, even a Huka Duet 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 DUET is a carefully engineered combination of an individually adapted wheelchair and
a bike with multiple gears.
•The maximum load for the detachable wheelchair is 275lbs.
•The road traffic laws and all safety regulations must to be obeyed in all situations.
•Every operation not described in this manual is forbidden.
•The DUET may not be used by the wheelchair user or the bike user alone when both parts
are connected.
• Structural changes may not be detrimental to traffic safety.
2.2 Safety and driving behavior
Before you take delivery of your new ready-to-drive Duet 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 bicycle this will be somewhat uneasy.
In order to use your Duet safely we advise you to (let) replace worn components like inner
tubes, outer tubes, and brake block immediately. These components are obtained from any
cycle shop or from your dealer.
1. The DUET biker must be at least 16 years old.
2. The DUET has to be checked for roadworthy condition before use.
3. All traffic laws are to be obeyed on all journeys on public roads. Every road user must act
in such a way that no other person can be jeopardized, damaged or hindered.
4. The wheelchair user has to be fastened with his safety belt according to his/her disability.
5. Always wear ANSI or BSI or GS safety helmets - both: the wheelchair user and the biker.
6. Caution on journeys on wet, slanting, uneven and slippery road surfaces or on tram rails.
7. For journeys in darkness a lighting system has to be mounted on THE DUET. At night switch
on the lights. Be visible; wear brightly colored clothing.
8. In pedestrian areas THE DUET may go at walking pace only.

No matter how sporty your Duet is, never get
tempted into too much enthusiastic
behavior on the roadway or riding on
and off
pavements. Your Duet can sustain visible or
invisible damage, which involves
additional risks.
2.3 Prevention of theft
A safety lock is mounted on most versions of the Duet. If you want additional measures
against theft than an additional cable lock is convenient to anchor you bicycle securely.
These locks are available in many cycle shops.
