sixthreezero Women's Simple Step-Thru 500W E-Bike
The STZ-630523 combines an aluminum step-through frame and forward-pedaling position with a 500W rear-hub motor. The listed 48V 10.4Ah lithium battery is approximately 500Wh. Shimano seven-speed gearing, a left-hand throttle and front and rear disc brakes complete the riding setup. Check saddle height, leg extension and control reach in the actual riding position before choosing it.
Speed and battery range
The Top Mobility product card lists a maximum speed of 28 mph. The page's feature text gives a different speed, so this description follows the card and does not assign its maximum to throttle or pedal-assist mode. The seller lists 20 miles in full-electric use and 20–40 miles with pedal assist; actual range varies with rider load, speed, hills, temperature, battery condition and riding mode. Plan with a return reserve.
Fit and use
The listing gives a 300 lb capacity and a rider-height range of 5 ft to 6 ft 4 in. Confirm that the step-through frame, seat position and handlebar reach are comfortable for the rider. Assembly is required; follow the supplied instructions and inspect the steering, fasteners and brakes before riding. A step-through frame does not replace a fit check or make every route suitable. Verify local e-bike speed, equipment and route rules before riding.
