More from this brandAll TS TST GRP LLC electric bicyclesOverview
A step-through cargo electric bike from TST with a 750W motor (1500W peak), 48V 15Ah removable battery, rear cargo rack, footrests and guard rails built for carrying gear or a child passenger.
The step-through frame and low mounting height are aimed at riders who want an easier on and off than a standard crossbar frame, and the seller specifically calls out the design as female-friendly. At 66 lbs with a 450 lb max load rating, it's built to carry real cargo, not just the rider.
- 750W motor, 1500W peak
- 48V 15Ah removable battery, up to 60 miles
- 450 lb max load capacity
- 180-day warranty
Who it's for
Families needing one bike that can run errands, carry a child on the rear seat, or haul light cargo, plus riders who prioritize an easy step-through mount over a sportier frame. Less suited to riders wanting the lightest possible bike for pure speed.
Pros and cons
- Rear rack and guard rails for passengers or cargo
- 450 lb max load capacity
- Step-through frame for easy mounting
- UL-certified removable battery
- One buyer received a bike with a broken display
- 1500W is a peak figure, not continuous output
Performance notes
The 750W motor with 1500W peak and 7-speed gearing across 3 riding modes gives enough torque for small hills even loaded with cargo, while front suspension and full-coverage fenders cut down on bumps and road spray. The UL-certified 48V 15Ah battery is rated for up to 60 miles in pedal-assist mode, less in throttle-only use.
