Bosch Active Line

The new Active Line is the drive for anyone who places great value on an elegant appearance. Due to its compact size, the Drive Unit can be integrated optimally into the bicycle frame. Its reduced weight and low centre of gravity provide for safe handling. Without any disturbing extraneous noises, you can experience pure riding enjoyment with gentle support up to 15mph. And anyone who wants to go faster will benefit from minimal pedal resistance above 25 km/h. 

The quiet, small yet powerful drive unit weighs in at just 2,9 kg and offers gentle acceleration up to 15.5 mph. The lightweight and reduced size ensure improved handling in all riding situations The intelligent 3-sensor concept of the drive unit takes more than 1,000 measurements per second to ensure a harmonious power characteristic. The drive complies with all road regulations and its compact design has the additional advantage in that it is attached to the bottom bracket, giving the bike an optimal centre of gravity. 

Award-winning design
Bosch sets new standards with flowing shapes and harmonious lines. The new Active Line has already won a Red Dot Design Award.
