Overview
Dual 2500W motors, a dual 38Ah battery system and a swappable passenger seat or cargo rack define the Happyrun G70 Pro, a 20 inch fat tire ebike aimed at off-road riding and hauling.
Happyrun pitches this as a 2-in-1 bike, swapping between a passenger seat and a rear cargo rack on the same frame rated to 330 lbs. The 5000W peak and 36 mph top speed are large numbers even by ebike standards, well above what most regions classify as a standard bicycle, so check local rules before riding at full power. Only one review is on file for this listing despite the 2.5 star rating shown, so there is limited public feedback to weigh.
- Dual 2500W motors, 5000W combined peak
- Dual 38Ah removable battery, 85+ mile claimed range
- 2-in-1 passenger seat or cargo rack
- NFC unlock with app based GPS tracking
Who it's for
Could suit riders wanting a high power, all-terrain ebike with the flexibility to carry a passenger or cargo. Not a fit for anyone who needs a street legal, license free ebike or wants a well documented review history first.
What buyers say
From Amazon customer reviews.
The one review on file describes an easy setup and a comfortable, quick ride, though this single account is not enough to speak to the bike's 2.5 star average.
