Easy handling

The innovative drive concept enables a drive unit weight of under 3 kilos and, thanks to the compact size, improved integration into the bicycle frame. The low centre of gravity in the middle of the eBike ensures easy handling. The Active Line is compatible with derailleur or hub gear systems. The optional backpedal function for hub gear systems helps you to brake particularly comfortably.
