Electric bicycles with mid-drive motors

Mid-drive

— the motor is installed near the bottom bracket, by the pedal assembly, and usually functions as a pedaling assistant: the rider pedals while the motor adds power through the chain or belt. Due to the use of gears, this drive is well-suited for climbs, trails, touring, and riding with a load, but it places more stress on the bike's transmission and generally requires the rider to participate in pedaling.
