Two years ago we first heard about Schaeffler's Free Drive system, which uses a generator instead of a chain or belt to power an electric bike . The technology is now entering its first commercial use, in fleets of electric bikes designed for commuting and cargo transportation.
Developed in collaboration with electric two-wheel drive specialist Heinzmann, the Free Drive system incorporates a generator integrated into the bottom bracket, a rear hub motor, a lithium battery pack and a handlebar-mounted control module.
As the rider pedals, they spin the generator. By doing so, it converts its mechanical energy into electrical energy, which is fed to the motor. That motor converts electrical energy back into mechanical energy, which is used to turn the wheel.
The generator regulates the amount of resistance the rider experiences while pedaling, based on the level of pedaling effort they have selected to maintain cruising speed. If you pedal harder than nec C Level Executive List essary, excess energy is stored in the battery. A regenerative braking system helps keep the battery recharged.
Although Schaeffler admits that the Free Drive system is about % less efficient than a chain drive at converting pedaling power into forward motion, the system also allows for much greater freedom when it comes to vehicle design. pedal-driven; After all, the crankset only needs to be connected to the rear wheel via electrical wiring.
Additionally, the Free Drive system reportedly requires much less maintenance than a chain drive.
Schaeffler has announced that the system will make its first commercial appearance in the mocci smart pedal vehicle manufactured by German company CIP Mobility. The latter firm will sell fleets of mocci electric bikes to corporate clients, who in turn will use them in bike-sharing projects, urban deliveries or other applications.
Along with its Free Drive transmission, some of the mocci's other features include sturdy one-piece monocoque wheels; a recyclable polyamide frame manufactured through a unique injection molding process; an integrated telemetry system; plus multiple rack mounting points and an optional cargo trailer.
