The Frikar e-bike uses three motors/generators: two function as part of the electronic transmission, and one acts as the assist motor/electronic brake. The assist motor’s power is limited to 250 W of continuous output, with a 25 km/h speed limit. The other motor works in tandem with the pedal generator, effectively acting as the human-powered transmission, and it continues to function beyond 25 km/h.
When you engage the electronic brake, it can be triggered either manually (for example, by pedaling backwards while moving forward) or automatically when the maximum downhill speed is reached. In both cases, the two wheel motors assist in braking the vehicle.
While battery-assisted speed is capped at 25 km/h, the pedal generator is not subject to this limit. By continuing to pedal, you can generate additional speed beyond the assist speed, depending on factors like incline, generator output, efficiency, and rolling resistance. However, for safety reasons, the maximum speed is limited to 50 km/h.
We store both pedaling energy and braking energy using electric batteries and do not rely on mechanical flywheels.
