Bosch presents new drives for e-bikes
With its new Performance Line, Bosch is presenting what it considers to be the most versatile drive system in its portfolio of motors for electric bicycles and pedelecs. The drive supports the driver up to a speed of 25 kmph, in the variant Speed up to 45 kmph.

With a maximum torque of 65 Newton meters (speed: up to 75 Nm) and up to 300 or 340 percent support for the cyclist, the drive unit offers sufficient power for sporty riding even in mountainous terrain. The unit is designed in such a way that the pedaling resistance is hardly noticeable in off-mode and above 25 kmph; the eBike rides like a conventional bicycle. This is mainly due to the newly developed motor control, which ensures a dynamic and sensitive response of the drive unit with its multi-sensor concept.

The drive unit has a magnesium housing and is lightweight. Even the more powerful Speed version weighs only 2.9 kg, around 25 less than its predecessor.

An additional 12-volt connection allows third-party suppliers to supply their components with power from the eBike battery. The Drive Unit allows chainrings to be fitted using "Direct Mount" or 104 mm standard mounting. The Q-factor of 175 millimetres helps the eMountainbiker to achieve an ergonomically favourable sitting position and a natural pedalling feeling. So that eMTBs with short cranks can also transmit power optimally, there is a special setting that the specialist dealer can make using the diagnostic software.
