//  NJ1 e-compact bike - Simply the best support!

NJ1 e-compact bike
The NJ1 el. compact bike consists of a drive unit and a stable girder chassis, which can be separated for transportation within seconds. As is the case for the NJ1 compact bike the packing size from 104 cm x 43 cm x 39 cm is unique among recumbent bikes.

There is a choice between BionX and neodrives drive systems for electric support. A speed of up to 6 km/h (3.7 mph) can be reached using the thumb accelerator. When pedalling, the drive assists with the set support level at a speed of up to 24.9 km/h.

The compact bike is available with a back pedal brake and/or chin strap, which facilitates operation especially for tetraplegics. There is also the option of a crank freewheel at the back. The pedals can be removed for manoeuvring to makepushing backwards easier.

High-quality switching and braking components from bike design produce precise switching and braking processes. The handbike equipment is variable, from touring bike to sports bike. The back angle can be infinitely adjusted without any tools. That way it can also be quickly adjusted to your needs when you are on the road.
