Our take on the GUGOIS 20" * 4.0 Electric Bike for Adults/Teens

The GUGOIS GT20 is a 20-inch fat-tire electric bike with a 750W rear hub motor, a 48V 15.6Ah removable battery and full suspension. It claims a 28 mph top speed, 80 Nm of torque and a 25-55 mile range, with a 7-speed drivetrain, five riding modes and an LCD display. The high carbon steel frame and 4.0-inch tires suit rough pavement, gravel and light trail riding. It is a heavy, budget-class fat e-bike; riders who want light weight or brand-name components should look at established names, while buyers chasing motor power and tire size for the money will find more here than on most 500W commuter bikes.
