Schaeffler
The generator on the pedal axle has no mechanical connection to the actual drive.
The Free Ride bike-by-wire drive presented by automotive supplier Schaeffler in 2021 will be on the road in Germany this year. One of the first customers is CIP Mobility GmbH, which will roll out the new pedelec drive concept with the Mocci fleet bike.
Unlike a classic pedelec pedal drive, the free ride solution does not have a mechanical connection between the pedals and the drive wheel. Rather, a generator developed by Schaeffler is used on the pedal axle, which ensures even resistance on the pedal and also absorbs the pedaling power. The electricity generated is used directly to drive the electric motor. If there is excess energy, this can be stored in a battery, as can electricity generated by recuperation, and used for propulsion if necessary.
The actual drive, a 250-watt motor, comes from the supplier Heinzmann, as do the control electronics, operating unit and battery. The software controls gear changes or changes in the operating modes. The Heinzmann components communicate with each other via a CAN connection.
Schaeffler Free Ride
The chainless e-cargo drive goes into series production.
Like other serial hybrid drives developed for pedelec use, the free-ride drive primarily offers design advantages. Especially with e-cargo bikes, complicated constructions are often required for the mechanical power transmission. There is also more freedom in design. The omission of sprockets, chains or belts also reduces maintenance and soiling.
The free-ride drive is therefore particularly interesting for three- and four-wheel cargo bikes and for fleet use, where low-maintenance technology is required. This is offered by the single-track Mocci cargo bike, which combines the chainless Schaeffler drive with an injection-molded plastic frame. It was also developed for use in fleets, including those of sharing providers.
