Free Drive system works without chain

The bike shown contains a battery that stores the excess power. It can also Braking energy returned will. There will be one for the entire system Continuous output 250 watts specific. According to Schaeffler Allowing more flexibility in bike construction and greater freedom in bike engineering.

Also suitable for cargo bikes

The advantage is obvious: without a chain and drive belt, the bike has fewer wear parts. For companies that operate fleets in particular, this means less maintenance is required, according to the broadcast. The drive is suitable for all types of bikes, regardless of whether they have 2, 3 or 4 wheels. This means that it can also be used for cargo bikes. All you need is to have a pedal motor.
