Finbike U3 Pedal Assist Commuter Bike 350W Motor 15.5mph

The Finbike U3 is a pedal-assist folding bike designed for urban commuting, featuring a 350W motor that keeps you at the legal 15.5mph speed limit. The aluminium alloy frame folds down to a genuinely compact size, making it practical for commuters who need to combine cycling with public transport or store the bike in a small flat or office. At just 16-inch wheels, the U3 is nimble in traffic and the tight footprint means it fits easily into train luggage racks and car boots.

The motor draws power from a 36V 7.8Ah battery that delivers around 12 miles of range in the highest assistance mode, though you'll likely see more distance if you use lower power settings for the majority of your ride. The single-speed drivetrain keeps things simple and maintenance-free, with no gear changes needed as the motor handles the work. Hydraulic disc brakes provide reliable stopping power regardless of weather, and Slime sealant is already fitted in the tyres to help prevent punctures during everyday riding. A small amount of surface rust is visible on the fork, but this doesn't affect how the bike performs—the U3 has only covered 185 miles and continues to work as intended.

This bike suits commuters covering short to medium distances in urban environments who want motor assistance without the complexity of gears. The folding design makes it particularly useful if you're splitting your journey between cycling and other transport, or if secure bike storage is limited. Riders needing longer range or planning hilly terrain regularly would benefit from considering battery capacity and terrain before committing, but for straightforward city commuting and portability, the U3 delivers practical everyday cycling.
