Overview
The Ruaioo MQ-G is a 3000W peak fat tire ebike with a 40 mph claimed top speed, a 52V 31.5Ah (1538Wh) removable battery rated up to 150 miles with pedal assist, and full suspension across 20 x 4.0 inch tires. Ruaioo markets it as an off-road and commuter dirt bike despite its Electric City Bikes category listing.
The category label on this listing reads Electric City Bikes, but the title, tires, and suspension point to an off-road build closer to an electric dirt bike, so the city bike category should be read as a listing quirk rather than a description of the bike. The 85 to 150 mile range spread is wide, with 85 miles reflecting pure electric use and the higher figure requiring pedal assist.
- 3000W peak motor, 40 mph claimed top speed
- 52V 31.5Ah (1538Wh) removable battery, 85-150 miles
- 20 x 4.0 inch fat tires with full suspension
- Dual hydraulic disc brakes, 330 lb frame capacity
Who it's for
Suited to riders who want a high power fat tire ebike with full suspension for off-road and mixed terrain use, and who understand the higher end of the range figure depends on pedaling assist. Less suited to anyone shopping specifically for a city commuter bike, despite how the listing is categorized.
Pros and cons
- 3000W peak motor with dual hydraulic disc brakes
- Large 1538Wh removable battery rated up to 150 miles with pedal assist
- Full suspension with 20 x 4.0 inch fat tires
- 7 speed Shimano gearing across 5 riding modes
- Listed under Electric City Bikes despite being an off-road build
- 150 mile range figure requires pedal assist, not pure electric riding
- 8-9 hour charge time for a full battery
Performance notes
The 3000W peak motor is rated for a 40 mph top speed, backed by dual hydraulic disc brakes and a 330 lb frame capacity. Full suspension combines a front fork with a rear spring shock, paired with 20 x 4.0 inch fat tires for grip on pavement, gravel, sand, and snow. The 52V 31.5Ah battery is rated for 85 miles in pure electric mode, extending to 85-150 miles with pedal assist, and takes 8 to 9 hours to fully charge. Five riding modes and a 7 speed Shimano drivetrain let riders match output to terrain.
