The ProductDome score is separate from the Amazon rating shown above: it combines the Bayesian-smoothed Amazon rating with evidence volume, tracked demand, and data quality across the 478 electric bicycles we track - how the scorecard works · full electric bicycles data report. Confidence: medium - useful but incomplete evidence.Last refreshed Jun 21, 2026. Data-computed, not a hands-on test. Compiled by the ProductDome Research Team.
Overview
A foldable fat tire electric bike from Euybike with a 750W motor (1000W peak) and a removable 48V 20Ah battery rated for up to 80 miles in pedal-assist mode. Front suspension, dual disc brakes, and a 7-speed drivetrain round out a package aimed at commuting and beach or trail outings.
Euybike frames this as a do-it-all folding e-bike, and the fat 20x3 tires and three riding modes back up the range of use cases. The battery alone weighs about 10 pounds, and the bike as a whole is heavier than it looks, which matters if folding it into a car trunk is part of the plan.
- 750W motor, 1000W peak, three riding modes
- 48V 20Ah removable battery, up to 80 miles
- Front suspension and dual disc brakes
- Foldable frame with adjustable seat and handlebars
Who it's for
Riders who want one folding e-bike to cover commuting, beach trips, and light trail riding, and who have somewhere to store or transport it without needing to lift it far. Less ideal for anyone who needs to carry it upstairs or into a car alone.
What buyers say
From Amazon customer reviews.
Assembly is repeatedly called easy, often completed by following the included video in under an hour. Several riders report stability even above 30 mph and performance they'd expect from more expensive e-bikes. The most common complaint is weight, with one buyer unable to lift it into a car, and a few noted minor factory issues like a rubbing brake or scratches that Euybike's support team resolved.

Performance notes
The 750W motor with 1000W peak handles hills and mixed terrain, and the three modes (pure electric, pedal assist, normal bicycle) let riders choose how much work the motor does. The front suspension and dual disc brakes are aimed at smoothing rough surfaces and stopping reliably, and the 20x3 puncture-resistant tires are suited to beach and mountain terrain as well as pavement.
