Several owners call it an easy, comfortable ride for casual use, but enough buyers received defective tires, controllers or handlebar hardware that a careful inspection on arrival is worth the time.

Overview
Folding fat tire electric bike from Gokeep, model USJX-L20A-G, built with a 20x3.0 fat tire, height-adjustable seat and a removable 52V battery.
The spec sheet lists a 750W brushless motor with 1300W peak power, while the title advertises 1300/1800W peak figures, so treat exact wattage as depending on configuration rather than a single fixed number. The folding steel frame is rated for up to 330 lbs and packs down to about 40 x 18 x 32 inches for storage or transport.
- 20x3.0 fat tires, front fork suspension
- 52V 13 or 18.2Ah removable battery, 35-86 mile PAS range
- Folding steel frame, 330 lb max weight capacity
- Shimano 7 speed, height-adjustable seat, front basket
Who it's for
Riders over about 50 or shorter in stature who want light pedal assist for local errands and appreciate a height-adjustable seat, and who are willing to inspect assembly closely given the range of hardware complaints below.
Pros and cons
- Height-adjustable seat suits multiple riders on one bike
- Removable battery with dual charging methods
- Folds down for storage or transport
- Front basket and rear rack accommodate cargo
Performance notes
The 52V 13 or 18.2Ah removable battery is rated for a 35 mile pure-electric range or up to 86 miles with pedal assist, recharging in 5-8 hours. The front fork suspension and 20x3.0 fat tires are built to smooth out rougher pavement and light trail use, and the 180mm disc brakes are sized for the bike's fat tire footprint, though braking and tire quality is exactly where more than one buyer ran into problems.
