The Macfox X1S is a Class 2 electric bicycle priced at $1,399. It features a 500W rear hub motor with a peak power of 750W, allowing for a top speed of 20 mph (32 km/h). The bike is designed with a moped-style geometry, a long bench seat, and 20 x 4-inch fat tires.
The base model includes a 500Wh (48V 10.4Ah) removable battery, providing a range of up to 28 miles (45 km). Users can opt for a dual-battery configuration for an additional $299 to double the range. The bike weighs 65 lb (29.5 kg) and comes equipped with front suspension and hydraulic disc brakes.
The electrical system of the X1S holds UL 2849 certification, and the single battery is UL 2271 certified. The manufacturer notes that the dual-battery setup falls outside the standard UL scope. The bike utilizes a cadence-based pedal assist system with three levels of support.
The throttle is positioned on the right side of the handlebars and is adjustable. The design prioritizes throttle-based riding over traditional pedaling, as the fixed-height seat and geometry are not optimized for cycling. The bike is marketed as a street-legal urban runabout.
