Price and specs last reviewed Jul 17, 2026
The SAMEBIKE M20-III is the flagship of the M-series moped lineup: dual 1000W motors (2000W combined, 3000W peak) deliver a combined 160 Nm of torque, more than the base M20's single motor, for serious acceleration and hill-climbing on its 20x4-inch fat tires. Two 48V 18Ah batteries (36Ah total) push manufacturer-rated range to 174 miles, with roughly 112 miles realistic across mixed pure-electric and pedal-assist riding. At 128 lbs with a 396 lb payload capacity, dual suspension, and hydraulic disc brakes, it trades portability for raw power and range. At $1,749, it costs $320 more than the base M20 in exchange for double the motors, batteries, and torque.
