wheel-e BionX D-Series
The wheel-e traction device allows you easy and independent progress in your own wheelchair. Be it pavements, forest trails or paths through a meadow, up or down hills: The powerful BionX D-Series drive system pulls the wheelchair and user without the use of muscle power. It is operated by a throttle grip on the handlebars. The drive system provides high torque of up to 50 Nm and runs silently.

You can choose from various rechargeable batteries with a range of up to 100 km. The twin rechargeable batteries have a change-over plug connection , so that you can switch between both batteries in just a few simple steps. The batteries are compatible with the NJ1 e-assistant with BionX drive systems and can therefore be used for both traction devices. Downhill, the recuperation (battery charging) can be activated in 4 stages. The recuperation increases the range by 10 to 15 % and reduces the work the braking system has to do on the hill. Powerful and high-quality brakes taken from bicycle manufacture ensure precise braking and a safe ride.

With the lower positioning of the batteries there is a lower centre of gravity, this provides optimum weight distribution and traction as well as good driving characteristics.

The wheel-e is delivered with a display showing the electrical drive system, this supports a maximum speed of 6 km/h. With this equipment, the wheel-e can be used in public areas and on the road. As an option, an additional display with a maximum speed of 15 km/h or 24 km/h can be ordered for use on private property. The displays can be quickly and easily swapped over depending on where they are being used.

The steering column is available in various lengths and the angle can be adjusted. This allows the optimal steering position for every user to be found.

The adaptation of the wheel-e to the wheelchair is done in a few steps using a PRO ACTIV front or central adapter. If a PRO ACTIV adapter is fitted for another PRO ACTIV product with an appropriate wheel size, this can also be used for the wheel-e. The adapter can be removed from the wheelchair in a few steps for transportation and the adapter can be uncoupled from the wheel-e. With a packing weight from 13.9 kg (without batteries and without the adapter) and its small packing size, the wheel-e is easily stowed.

A comprehensive range of accessories are available, also specially designed ones for functionally-restricted users.
Packing weight from 13.9 kg and packing size from 110 x 62 x 62 cm
  • Easily stowed into the car and simple to transport.

Choose between a central or front adapter
  • Central adapter: Mount to axle or cross-tube (with rigid frames) under the seat, or to the folding mechanism (with folding frames).
  • Front adapter: Mount to the front frame tubes. Can be adjusted to suit different tube diameters and thereby also be used for third-party wheelchairs.
  • It can be removed from the wheelchair with just a few actions.
  • When uncoupled from the wheelchair, there is hardly any more weight on the wheelchair and thereby no functional impairment (e.g. folding mechanism).
  • One adapter can be used for all PRO ACTIV adaptive bikes, towing devices and attachments with a corresponding wheel size.

Optimal adaptation to the requirements and abilities of the driver
  • Thanks to the angle-adjustment on the steering column, the handlebar position can be adapted to the needs of the user.
  • You can select from various lengths for the steering column.

An optional parking stand can be folded away while driving to save space
  • Makes coupling and uncoupling easier as the towing device is parked at the required adaptation height.
  • When uncoupled, the towing device is stable.

Effective brakes
  • Magura hydraulic disc brakes.

Long range of the batteries
  • Lithium-manganese technology.
  • Selection of batteries with ranges up to 100 km.
  • Simple to change between 2 batteries using the swap-over plug connector.

Speed  Equipped with a display with a maximum speed of 6 km/h: PRO ACTIV delivers the wheel-e with a display for the electrical drive system which supports a maximum speed of 6 km/h. With this equipment, the wheel-e can be used in public areas and on the road.

Optionally it can be equipped with an additional display with a maximum speed of 15 km/h or 24 km/h: An additional display with a maximum speed of 15 km/h or 24 km/h can be ordered as an option. PRO ACTIV points out that the use of the wheel-e with this additional display is only permitted in certain countries on public roads and otherwise only on private property. Without an insurance plate and operating approval, driving the wheel-e with a maximum speed of 15 km/h or 24 km/h is not permitted in Germany on public areas, roads, paths and spaces in accordance with the Road Traffic Act (Straßenverkehrsordnung). It is also not permitted to use it on cycle paths according to the Road Traffic Act in Germany. PRO ACTIV also points out that the use of the wheel-e with a maximum speed of 15 km/h or 24 km/h on public areas, roads, paths and spaces in Germany is an offence against the insurance obligation in accordance with Art. 1 German Compulsory Third-Party Insurance Act (Pflichtversicherungsgesetz) for which the user could be punished in accordance with Art. 6 Para. 1 German Compulsory Third Party Insurance Act.

If the wheel-e is to be used in another country with a display giving a maximum speed of 15 km/h or 24 km/h, the user must first find out about the applicable regulations and laws in that country.
