Typically, e-bike mid-mounted motors are driven by an electric motor and a combination of gears and planetary gears, which makes this type of mid-mounted motor clunky, heavy and noisy. More moving parts also mean more things that can break and act as a source of noise. TQ Group’s developed a lightweight and extremely compact motor design around the bottom bracket, consisting of only a few parts and making the motor virtually invisible. By dispensing with additional gears that cause friction, noise, wear and potential sources of error, the drive unit could be made even more efficient.
