Overview
The Vivi Gopina is a folding fat tire electric bike with a low step frame, a 48V removable battery and pedal assist across 7 gears. It ships about 85% assembled and folds down for storage or a car trunk, aimed at riders who want one bike for city streets, sand or snow.
Vivi lists a 350W rated motor that peaks at 500W, good for a top assisted speed of 20mph rather than aggressive off-road climbing. The 16x3.0 inch fat tires and front shock give it a stable ride on gravel or light snow, though this is a commuter and errand bike first, not a mountain bike. SGS certification to UL2849 covers the battery and electrical system safety standard.
- 48V removable battery, 4-6 hour charge
- 16x3.0 inch puncture resistant fat tires
- 7-speed pedal assist with 3 working modes
- LCD display and integrated headlight
Who it's for
Suits adults or teens who want a foldable commuter that handles mixed pavement, sand or light snow without needing a bike rack, thanks to the low step frame and adjustable seat and handlebar height. Less suited to riders chasing long range or high top speed, since the quoted range tops out around 40 miles and the assisted speed caps at 20mph.
Pros and cons
- Removable 48V battery with BMS protection
- Folds down for car trunk storage
- Low step frame eases mounting and dismounting
- SGS certified to UL2849 safety standard
- Assisted top speed limited to 20mph
- Requires about 30 minutes of final assembly
Performance notes
The 48V 7.8Ah battery charges fully in 4 to 6 hours and pairs with a battery management system for protection during charging and discharge. Pedal assist, 7-speed gearing and 3 working modes let riders shift between throttle only, pedal assist or manual pedaling, while the LCD display tracks speed and mode. The fold-up frame and removable handlebar are meant to fit in a car trunk once folded.
