The VIVI 20-inch fat tire electric bike is a folding step-through commuter with a 500W rear hub motor, a 48V 10.4Ah removable battery and a 7-speed drivetrain. It tops out around 19.8 mph and runs four modes: throttle, pedal assist, manual pedaling and cruise control. The 3-inch fat tires, front suspension fork and dual disc brakes make it steadier on rough pavement and light trails than a standard 20-inch folder. It suits riders who want a compact, car-trunk-friendly ebike for commuting and errands; against rivals it wins on folding convenience and tire width but carries more weight and a modest battery.

This is a foldable step-through electric bike with 20 x 3.0 inch fat tires. It has a 48V 500W rear hub brushless motor and a 7-speed transmission. The top speed is 19.8 mph, and the bike is UL2849 certified.
The frame is carbon steel and folds for carrying and storage, so it fits in a car trunk and can be taken on public transportation. The stem and seat are height adjustable for riders from 5'1" to 6'3". It has a padded seat, fenders, a rear cargo rack and integrated lights.
Front and rear disc brakes handle stopping, and a shock-absorbing front fork and thick anti-slip tires cushion bumps. There are four riding modes: pure electric, pedal assist, manual cycling and cruise control. The removable 48V 10.4Ah lithium battery can be charged on the bike through its charging port or taken off and charged separately. A full charge takes 4 to 6 hours.
