maxon puts the expertise gained in the development of the BIKEDRIVE e-bike system to use in other areas of e-mobility too. For example in drive systems for electric scooters and trikes, in customized drives for professional and extreme sports, and even in drives for electric wheelchairs and rehabilitation vehicles. These applications too require a combination of motor, gearhead, and battery management that works together reliably and precisely.

Our product recommendations.

The e-bike drive unit consists of a BLDC internal-rotor motor and a low-noise performance planetary gearhead. The Q-factor starts at just 155 mm. The integrated electronics and sensors ensure sensitive support in all riding situations. The patented, innovative freewheel has no noticeable resistance – both when backpedaling and when riding without electrical support. It is possible to install either racing or MTB chain rings.

A control element gives total control over the e-bike and can be connected via Bluetooth (BLE) to a smartphone or via ANT+ to other devices from Garmin, Sigma, or o-synce. The three support levels can be individually configured with the app. Three ride modes are programmed at the factory: Cruise (gentle tailwind), Push (sport mode), Blast (lots of power for steep inclines). Inconspicuous and intuitive shifters for the racing bike or mountain bike handlebars are available as an option.

With ANT+ or Bluetooth (BLE), you can easily connect other devices too: Garmin, Sigma, o-synce, etc. For retailers, there is an intuitive Service app.
