Last year we talked about the transmission system for electric bicycles that lacked any mechanical connection between the pedals and the wheels. The Free Drive system , created by a partnership between the German companies Schaeffler and Heinzmann, finally goes into production.
In essence, the design turns e-bikes into another type of hybrid vehicle.
Although current ebikes are not identical to each other, their form factor is limited by the fact that their pedals have to be mechanically attached to the rear wheel. Free Drive removes this limitation, allowing an unlimited number of new designs.
In current electric bicycles, or those that are not, the cyclist's pedaling force is transmitted to the rear wheel through a chain, belt or even axle transmission. In all cases, however, a moving mechanical device must operate between the plate and the wheel.
On the contrary, Free Drive only requires electrical wiring to connect one to the other.
To achieve this, an electrical generator is mounted on the pedals. The rider spins the generator instead of a plate, which converts that kinetic energy into electrical energy. That electricity flows to the motor and is converted back into kinetic energy to propel the bike. Any additional electricity generated above what the motor needs is stored in the battery. The battery can also be charged through a power outlet, which is most likely.
Although the Free Drive system has multiple uses, cargo bikes appear to be one of the main applications. Most cargo bike designs are UK Phone Number limited by the need to create a long tunnel for a bike's chain to reach the rear wheel or gearbox. But Free Drive allows cargo bikes to be designed differently, lowering the floor or deck and creating a much more stable platform that is not limited by the requirements of the bike's mechanical drivetrain.
Electric cargo bikes play an increasingly important role as replacements for delivery vehicles in cities around the world.
