Duet Junior 

 
The Duet is a combination of an individually adaptable wheelchair and a bike with multiple 

gears. The front part of the cycle consists of a manual wheelchair that can be connected and 
disconnected to the cycle mainframe. When connected, the wheelchair is the front part and 

steering part of the cycle. When disconnected, the wheelchair can be used as a genuine 
manual wheelchair. 

 
 
 
 

With the aid of this manual, with its clear drawings and practical instructions, you will be 
able to get even more enjoyment from your Duet 

II

 Junior. It is important that you take 

the time to read it carefully and then tot keep it within arm’s reach for use in the future. 

In the first instance, please approach your dealer if you have any questions and/or 
complaints. 

 
When you pick up your Duet 

II

 Junior, all the components described in this manual will 

have been properly adjusted in accordance with your requirements. Any components to 

be delivered separately will also have been fitted by your dealer. 
 

Some components must be adjusted again after a time. It is best to have this carried out 
by your dealer. We also advise when you want to make adjustments yourself, you 

always consult your dealer before doing so. He is not only the supplier of your bicycle, 
but also a specialist who can advise you on such matters. 
 

Check whether there are any tips and/or recommendations before you start work on 
your bicycle. These manufacturer’s tips and recommendations must always be followed.  

These tips and recommendations will increase your safety and improve the cycling 
comfort of your Duet
