Finbike U1 City Electric Bike - 250W Motor and 45 km Range

Finbike U1 City Electric Bike is the documented model behind the 250W, 14-inch folding city-bike description. Its compact frame uses a 36V 7.8Ah battery, pneumatic tires, and a claimed 22-28-mile range for urban riding.

Compact Folding Bike Design

The U1 has 14 x 1.95-inch pneumatic tires, a steel alloy frame, rear suspension, and front and rear disc brakes. Finbike's U1 specifications list a 51.1 lb bike weight and a 264 lb maximum load.

The recommended rider height is 4 feet 11 inches to 6 feet 1 inch. The LCD instrument displays riding information, while the headlight and taillight add equipment for low-light travel.

Motor Battery And Range

A 250W motor provides the rated output, with a stated 350W peak. The system offers three power levels at 6.2, 9.3, and 15.5 mph, while the listed top speed is 15.5 mph.

The battery specification is 36V and 7.8Ah, using 18650 cells. Finbike lists a 22-28-mile range and a 3-4-hour charging time with the supplied charger, so the published distance is tied to the brand's stated operating conditions.

The U1 also carries CE certification and a two-year warranty for the motor, controller, and frame. Tires, the saddle, decorative strips, and fastening covers receive six months of coverage; other parts receive one year.

How It Compares

Finbike's own comparison listing places the U1 below the U3 in the range lineup: the U1 is listed at 45 km, while the U3 is listed at 55 km. The U3 is also listed at 16 kg, compared with 23.2 kg for the U1, making the U1 the heavier documented option.

The U1's 14-inch wheels favor compact storage over the larger wheel formats found on Finbike's 26-inch models. Its 120 kg load rating, three assist levels, LCD display, lights, and dual disc brakes give it a defined equipment set for short urban trips.

Best Fit For Urban Trips

The U1 fits riders seeking a folding electric bike with a 250W motor, small wheels, and a stated 51.1 lb weight. Its 264 lb load rating and 4-foot-11-inch to 6-foot-1-inch height guidance define the documented user envelope.

The practical tradeoff is the 23.2 kg mass: folding reduces the bike's storage footprint, but it does not make the bicycle light to carry. The U1 is best placed among compact commuter e-bikes for paved city travel, short commutes, and storage-sensitive use rather than lightweight portability.
