The dual motor setup delivers real climbing and traction, but expect the range and top speed figures to be optimistic and check the brake wiring and footpegs before your first hard ride.

Overview
The HAPPYRUN G70 Pro is a dual motor fat tire electric bike, built around an 18Ah plus 15Ah dual battery pack, 20 inch fat tires, full suspension and hydraulic disc brakes. A second seat converts to a cargo rack, and Happyrun rates it to carry up to 330 lbs.
This is an off road focused build first: dual motor traction shows up repeatedly in owner accounts of steep hills and mud, and the frame is rated to carry a passenger or cargo. Advertised numbers (36 mph top speed, 85 plus miles) run ahead of what owners actually report, so treat those as ceiling figures rather than typical results.
- 5000W combined peak dual motor
- 18Ah + 15Ah dual removable battery
- 20 inch fat tires with full suspension
- Hydraulic disc brakes, front and rear
Who it's for
Suits someone riding trails, hunting land or mixed dirt and pavement who wants dual motor climbing power and doesn't mind pedaling less and charging more often than the spec sheet implies. Not the choice for a rider who needs the full advertised range guaranteed, since quality control complaints do show up.
Pros and cons
- Dual motor traction helps on steep terrain
- Rear seat swaps for a cargo rack
- Full suspension and hydraulic disc brakes
- Support responded quickly to setup issues
- Real world range falls short of claims
- One unit had reversed brake wiring, broken footpeg
- Throttle has a noticeable built-in delay
Performance notes
With both motors engaged, the dual hub setup adds traction in mud and clay and noticeably eases steep climbs, according to multiple owners. Real world range and speed reports run well under the spec sheet: one owner clocked a 32 mph top speed and estimated closer to 25 miles per charge running both motors continuously, against the advertised 36 mph and 85 plus miles.
