Overview
HAPPYRUN G70 Pro is a dual-motor electric bike with a claimed 5000W peak combined output, 20 inch fat tires and a removable dual-battery pack rated for over 85 miles of range.
The frame converts between a passenger seat and a rear cargo rack, and Happyrun positions it as both a commuter and an off-road ride, though the top speed and torque figures come from Happyrun's own listing rather than independent testing. The battery splits into a 20Ah and an 18Ah unit that can each be removed for charging away from the bike.
- 5000W peak combined dual motor output
- 38Ah removable battery, 85+ mile claimed range
- 20 inch fat tires with front fork suspension
- NFC unlock and smartphone app
Who it's for
Riders wanting a fat tire ebike that swaps between passenger duty and cargo hauling, with long claimed range from a removable battery, are the target. Those needing clear street-legal status at the stated top speed should check local rules first.
Pros and cons
- Removable dual battery pack for charging away from the bike
- Converts between passenger seat and cargo rack
- Hydraulic disc brakes and front suspension
- NFC unlock and companion app for GPS tracking
- Arrives 85 percent assembled, requiring some setup
- Stated 36MPH top speed may exceed local ebike class limits
Performance notes
The listed 5000W figure is a combined peak output from two 2500W motors, which typically exceeds sustained continuous output; real-world hill climbing and acceleration will depend on rider weight and terrain. Hydraulic disc brakes and front fork suspension with a seat shock absorber are the stated components handling stopping power and impact absorption on rough ground.
