Xiaomi YZZ4016GL Mi Smart Lightweight Foldable Bicycle E--Bike 250W - Black A

The Xiaomi Mi Smart folding bike is an electric bicycle built around a compact longitudinal fold, making it easy to pack away or carry when you're done riding. The frame design keeps the main tube unfolded, which means the structure stays solid and predictable—there's no risk of folding joints loosening up after repeated use, something that can happen with traditional folding designs where the main load-bearing members get interrupted by fold points.

The motor is a 250W brushless unit fitted with TTM torque sensing technology, which means it reads how hard you're pedalling and outputs assistance accordingly. This makes the electric help feel natural and proportional rather than sudden or artificial. The system caps out at 25km/h of assisted speed, keeping it within legal e-bike limits in most regions. A Samsung 18650 mAh battery powers the motor and gives you around 45km of range on a single charge. The battery is removable, so you can take it indoors to charge away from the bike—it takes three hours to go from flat to full.

If the battery runs down before you reach home, the bike doesn't strand you. A Shimano Nexus 3-speed hub gear lets you pedal normally using traditional mechanical shifting. This is useful for any terrain—drop into an easier gear for climbs or headwinds, use a harder gear on flat sections or with a tailwind. It's straightforward and reliable, with minimal maintenance compared to derailleur systems.

This black folding e-bike is designed for urban commuters and anyone who needs to combine cycling with public transport or storage in tight spaces. The fold makes it practical for train journeys, storing in flats, or keeping in an office cupboard. The electric assistance helps with longer distances or when you're tired, while the mechanical backup means you're never completely dependent on battery charge.

This particular unit is graded as Open Box Grade A, meaning it's new and unused with the box seal removed. Minor box damage may be present, but all accessories are included as standard. A 12-month warranty is supplied with the bike.
