Xiaomi Smart 250W Power 25km/h 16" Wheel TFT Display Folding E--Bike - Bike A

The Xiaomi Mi Smart Electric Folding Bike is built for urban commuting where you need to move quickly without arriving sweaty, and where storage space is tight. Cities increasingly demand compact, efficient transport, and this folding e-bike delivers exactly that. It weighs approximately 15kg and folds down to 1290mm × 540mm × 1010mm, making it genuinely practical to carry on trains, buses, or stow in a car boot. If you regularly combine cycling with other transport methods, or live in a flat without secure bike storage, the fold works well enough to become routine.

The frame is made from aluminium alloy with a matching aluminium fork, keeping weight down without sacrificing rigidity. The 16-inch wheels are typical of compact folding bikes—they make the package genuinely portable and help the bike feel responsive in traffic, though you do need to maintain momentum on longer flat stretches more deliberately than you would on a larger-wheeled bike. The aluminium 33.9mm seatpost adjusts to fit different rider heights, and the overall geometry suits the stop-start nature of city riding rather than distance touring.

The 250W front hub motor reaches 25km/h, which is the legal UK limit for e-bikes without throttle assistance. A 36V 2A power supply drives the motor, and the 5800mAh lithium-ion battery stores 208.8Wh of energy. Real-world range depends on terrain, your weight, and riding mode, but this capacity is realistic for daily urban commuting. The charger accepts standard UK 100-240V input and takes roughly 2.5 to 3 hours for a full charge.

What makes this bike different from a basic e-bike is the TMM4 force sensor on the rear wheel. This tracks how hard you're pedalling and adjusts motor assistance accordingly, scaling between four riding modes. Rather than having the motor do the work regardless of your input, it responds to your pedal pressure, which means you can choose how much effort you want to invest on any given ride. One day you might want pure assistance; another day you might want a genuine workout with light support.

Braking uses a slipper brake on the front and a Shimano IM31 roller brake on the rear. Roller brakes work well in wet conditions and require minimal maintenance, though they do take slightly longer to feel familiar if you're used to rim brakes. The bike runs through a Shimano 3-speed internal hub, which is straightforward to operate and manages hills without drama. Three gears won't excite riders who like options, but for urban commuting on mixed terrain, the range is adequate.

The 1.77-inch TFT display shows your speed, battery level, distance, and which assistance mode you're in. It connects via Bluetooth at 2402-2480MHz, though this is mainly for system diagnostics rather than smartphone integration in the way modern bikes offer. The display is small but readable in daylight, and the interface is uncomplicated.

This bike suits commuters who need to combine cycling with public transport, or anyone working within a few kilometres of home who values speed over exercise. It's practical for carrying shopping or small cargo, and the electric assistance means hills and headwinds don't become obstacles. If you're after something sporty, lightweight for racing, or capable of genuine off-road work, you'll look elsewhere. But for reliable, efficient city-to-city movement that folds to fit your lifestyle, this is a straightforward choice. The aluminium construction keeps corrosion at bay, and the 12-month warranty covers manufacturing faults within that period.
