Ultralight e-motor for bicycles – retrofittable


Riding longer distances in a shorter time with compensation for terrain conditions. Cycle commuters with a light motor option, which can be activated on demand, cycle in a sporty, relaxed manner in predictably shorter travel times over longer distances and more mountainous route profiles. More riding comfort motivates for more movement outside. Cycling with pleasure invites you to use the bicycle as a means of transport on a daily basis. The VELOSPEEDER creates more possibilities in everyday life to extend the radius of action on a timeless light bike in a modern way.


Safety and comfort on slopes and in windy conditions. Extend your radius of action. A lightweight motor offers touring cyclists more safety on long distances, on slopes, and in headwinds. With motor support, you can cycle actively for the most part and master the terrain more easily. A motor should help with the pedalling without taking most of the cycling away from you. The aim is to make you master obstacles and ride as comfortably as possible with your own activity. The VELOSPEEDER makes it possible to discover unknown terrain spontaneously and easily.

With the VELOSPEEDER the classic bicycle becomes a light e-bike.

    Yesterday I took part in an ADFC winter / spring tour (85 kilometers / 650 meters in height). I only used the motor on longer climbs or when I felt overwhelmed in view of the sporty superiority of my fellow cyclists. Remaining capacity of the battery at the end of the tour: 3 beeps. (...) The result was absolutely convincing! This makes the choice of your motor a complete success for me!
