sixthreezero 20-inch Simple Step-Thru 500W E-Bike
The STZ-630628 uses a step-through frame and 20-inch wheels for a compact-riding position. Top Mobility lists a 48V, 500W motor, 20 mph maximum speed, 300 lb weight capacity and rider-height range of 4 ft 11 in to 6 ft 4 in. Merchant confirmation identifies the included battery as 48V 10.4Ah. Check the riding position, control reach and stopping response before choosing the bike.
Battery and range
The listing gives a range of 25–40 miles. Treat that as an estimate rather than a guaranteed trip distance: rider load, speed, hills, temperature, battery condition and riding mode affect range. Plan for a return reserve and charge with the supplied equipment. The listed maximum speed is 20 mph; check local rules for e-bike speed, equipment and route access.
Fit and transport
Confirm the 4 ft 11 in to 6 ft 4 in rider-height range against the individual rider, and make sure the step-through frame, seat position and handlebar reach work together. The listed specification table shows 20 × 1.95-inch tires and front and rear disc brakes. Assembly is required; follow the supplied setup instructions and inspect the brakes, steering and fasteners before riding. A step-through frame does not replace a fit check or make every surface suitable.
