NJ1 e-assistant neodrives
The NJ1 e-assistant always permits easy and independent forward motion with your own wheelchair. The neodrives drive system supports you when you are pedalling at the set support level (5 support levels 60%, 120%, 180%, 240% and 300 %) up to 24.9 km/h. A speed of up to 6 km/h forwards and 1.5 km/h backwards can be reached using the pushing assist without pedalling. The pushing assist is controlled using the control satellites.

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 neodrives drive system is a high-quality Pedelec wheel hub drive ”Made in Germany”. No switch is integrated in the motor, so that you can choose from a large selection of complementary derailleurs.

Downhill, the recuperation can be manually activated or activated automatically using the downhill assistant. The downhill assistant assures safety travelling downhill and a high level of comfort as no permanent re-adjustment of the recuperation level is required. The battery is charged ”automatically” without the user having to remember to activate the recuperation mode. Recuperation mode can increase the range by up to 10 per cent. In addition, the brakes are not used as much downhill due to the recuperation.

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.
