During Spezi, recumbent manufacturer Challenge revealed the front suspension for the Alizé trike, which happens to be a development from some years ago. The already earlier developed suspension was taken into account when the front wheel arms were recently designed.

Base of the suspension is the degree-thesis of trainees at Challenge. The traineeship started in 2006, the thesis was completed in 2007.

Early marketing research in trike country USA revealed that local dealers didn't see added value in 2006 for the front suspension. In Europe 2010 the situation is clearly different.

On the image the resin front suspension can be seen. The design intends to create it in carbon. On this prototype the suspension action is clearly visible.

The principle behind this suspension is to maintain alignment and wheel position while in action. The blade shape optimises this. The designers fulfilled these requirements with the new Alizé suspension, which will be available in due time.
