Electro Adaptive Bikes Proactiv NJ1 E-Assistant BionX IGH3

The NJ1 e-assistant BionX ”IGH3” is a wheelchair traction device with purely electric, electrically assisted and manual driving function and a 3-speed hub gear system. It allows for easy and independent travelling without muscle force or having to leave your own wheelchair behind. It is stable and has outstanding handling characteristics. A speed of up to 6 km/h (3.7 mph) can be reached via the thumb switch only.

To maintain or enhance your cardio function, you can pedal at the same time. In doing so, there are four support levels: 35%, 75%, 150%, 300% up to 24.9 km/h (15.5 mph). The motor is maintenance-free and available for 20'', 24'' and 26'' wheels. Thanks to lithium-mangan technology one battery has a range up to 45 km (28 miles).

This traction system is available with a back-pedal brake and/or chin switch which makes operation by tetraplegics particularly easy. There is also the option of a crank freewheel at the back. The cranks can be removed to manoeuvre back and forth, and you can comfortably reverse using the hand rims.

The 3-speed hub gear system can be operated via a turning handle and can be combined with the Mountaindrive pedal crank gearshift (up to 6 gears, not in combination with back pedal brake).
