A powerful, well-equipped fat-tire e-bike for the price, but assembly quality and instructions varied enough between buyers that hands-on setup should be expected.

Overview
The Rpint E500 is a fat-tire electric mountain bike built around a 500W motor (1500W peak), a 48V 15Ah removable battery, and a claimed 60-mile pedal-assist range for off-road and commuting use.
Full front and rear suspension paired with 20x4 inch tires is meant to absorb rough terrain, and the bike offers throttle-only, pedal-assist, and manual modes with a 7-speed drivetrain. It carries UL 2271 and UL 2849 safety certification, validated by SGS, which covers the battery and the bike as a system.
- 500W motor, 1500W peak power
- 48V 15Ah removable battery, up to 60 miles PAS range
- 20x4 inch fat tires with full suspension
- UL 2271 and UL 2849 certified, validated by SGS
Who it's for
Suits riders who want power for hills and light off-road trails and are comfortable doing their own bike assembly and basic maintenance like chain tension and brake pads. Not a fit for anyone expecting a fully assembled, low-maintenance appliance, since more than one buyer needed extra tools and ongoing upkeep to keep it running well.
Pros and cons
- Reaches 27.5-35 mph depending on ride mode
- Full suspension and fat tires handle rough terrain
- Removable 48V battery charges in about 5-6 hours
- Assembly instructions incomplete or missing for one buyer
- Needs regular chain and brake pad maintenance
- One buyer needed a drill for handlebar screws
Performance notes
Real-world top speed reports ranged from about 27.5 mph on throttle alone to 35 mph in the highest assist mode, and one owner logged 500 miles as a daily city commuter with light off-road trail use.
