Description

The Super73 B1G is the tall-rider A-Series model, a Class 2 moped-style e-bike with a 52 V, 10 Ah battery of 520 Wh and a 500 W nominal rear hub motor (torque not published). It has two-piston hydraulic disc brakes, a rigid fork and frame, and 20 in tires 4.5 in wide in front and 5 in at the rear.
