User cycling (video)
Exercise bike with 27 gears (manual gears), adjustable back angle and shock absorbers.
Model name: Top End Force 2
Sitting up straight works well for users with good trunk balance. This way trunk strength can also be used for cycling. Users with poor or no trunk balance can set the angle of the back to lean backwards more or they can recline.
To compete in races, users lie down on the bicycle to reduce air resistance.
The disadvantage of the arm cycle is that you can’t bring your wheelchair along.
