Overview
The Macfox X1S is a Class-2 fat tire electric bike built around a 500W brushless motor rated to 750W peak, with a 20 mph top speed that keeps it street legal without a license. Fat 20x4 tires and a front shock absorber target daily commuting and campus riding rather than off-road use.
- 500W motor, 750W peak power, 65Nm torque
- 20 mph max speed, no license required (Class-2)
- 20x4 fat tires with multi-section tread
- Front shock absorber for road bumps
Who it's for
Riders who want a straightforward, no-license commuter bike for neighborhood or campus trips. Less suited to anyone expecting off-road capability or hoping to skip a pre-ride bolt check, since more than one buyer found the front wheel bolt worked loose early on.
Pros and cons
- Reaches top speed quickly off the line
- Minimal assembly, mostly front wheel and bars
- Fat tires grip well across surface types
- Stable steel frame at speed
- Front axle bolt has come loose for multiple owners
- Customer service response is inconsistent
Performance notes
The 500W motor's 750W peak and 65Nm of torque get riders to the 20 mph limit in a few seconds, per one owner's timing. The multi-section tread on the 20x4 tires is built for grip across pavement, sand, and mud, and the front shock absorber is meant to blunt repeated road impacts rather than serious off-road hits.
