Overview
A 20x4 fat tire electric bike with a 500W motor rated to 25 mph, a 48V 14.5Ah removable battery, front suspension and Shimano 7-speed gearing, built with a step-through frame and adjustable handlebars and seat.
The listing quotes a 41 mile range while the attribute copy separately claims 40 miles pure electric and 75 miles pedal-assist, figures that do not fully line up, so treat the range as approximate rather than exact.
- 500W motor, up to 25 mph
- 48V 14.5Ah removable battery
- Front suspension and Shimano 7-speed
- Step-through frame, adjustable handlebars and seat
Who it's for
Fits adult riders between roughly 5'5 and 6'1 who want a fat tire commuter with adjustable fit and step-through access. Less suited to shorter riders, since one reviewer with a 29 inch inseam could barely touch the ground even at the seat's lowest setting.
Pros and cons
- Customer service resolved shipping and parts issues
- Handled 500+ miles with only minor issues
- Rear rack included for carrying gear
- Adjustable handlebars and seat for fit
- Seat may not lower enough for shorter riders
- At 80 lbs, awkward to handle for some riders
- Stock seat uncomfortable on longer rides for one buyer
Performance notes
The 500W motor with front suspension handled 500 miles for one reviewer with only a faulty cable needing replacement, and a rear rack lets it carry gear for commuting. Riders around 270 lbs reported sustaining 21-23 mph, and the fat tires held air without noticeable loss over hundreds of miles for at least one long-term user.
