The Frikar e-bike uses series hybrid propulsion, with no direct mechanical connection between the pedals and the wheels. Instead, all energy transfer from the rider to the wheels is done via electric wires. The vehicle features one 250W motor for electric assist and one 250W motor for series hybrid propulsion, ensuring it remains legal in all EU countries. While 250W may seem modest, the vehicle has been designed to be exceptionally energy efficient.
While the drive train incurs significant energy losses when measured as a percentage, the actual power loss is relatively small. This is because most humans can only sustain 50-100W of leg power over an extended period. These small losses can easily be offset with just a few hundred grams of additional battery capacity per hour of cycling. Given that the Frikar velomobile uses two motors and one generator, opting for a high-efficiency hybrid drivetrain would increase costs significantly, more than the extra battery capacity required.
