NJ1 e-assistant BionX ”IGH3”
The NJ1 e-assistant always permits easy and independent forward motion with your own wheelchair. The BionX IGH3 supports you when you are pedalling at the set support level (4 support levels 35 %, 75 %, 150 % and 300 %) up to 24.9 km/h. A speed of up to 6 km/h can be reached using the starting assist without pedalling. The starting assist is operated using a thumb control switch (below the display or on the handlebar) or via a chin control lever.

The traction device is available with a back-pedal brake, which makes its use particularly easy for paraplegics. In addition, there is also the option of a crank freewheel at the back: The cranks can then be uncoupled for manoeuvring and it can be moved backwards easily using the handrims.

The BionX IGH3 is powerful for permanent support and has an integrated 3-speed hub gear. Gear change is done using a rotary handle for manual operation, or via the automated controller for chin operation. The hub gear can be combined with the Mountaindrive pedal crank gearshift (up to 6 gears, not in combination with the back-pedalling brake).

Downhill, the recuperation can be manually activated in four levels.

The traction device can be operated on public roads, as part of the Pedelec rules, without insurance and registration.

A comprehensive range of accessories is available, also for function-impaired users.
