DYU A1F 16 Inch Wheel Electric Folding Foldable Commuter Bike Bicycle

The DYU A1F is a compact electric folding bike designed for urban commuters who need something genuinely portable. The 16-inch wheels and aluminium alloy frame fold down small enough to stash in a cupboard, under a desk, or on a train, and at 21kg it's heavy enough to feel substantial but not so much that carrying it becomes a chore. It strikes a practical balance between portability and usable everyday transport.

Power comes from a 250W motor paired with a 36V 7.5Ah battery that delivers between 25 and 40 kilometres on a single charge, depending on how much you use the motor and what terrain you're covering. The battery charges in 3 to 4 hours, which means an overnight top-up gets you ready for the next commute. The bike offers five assistance levels including full electric mode and three stages of pedal assist, so you can dial in how much work the motor does or switch it off entirely and ride it as a regular bike. The motor caps out at 25 kph, respecting the legal limit for electric bikes in the UK.

Day to day, the A1F runs a single-speed drivetrain with mechanical disc brakes, which keeps things simple and low-maintenance. This setup works fine for relatively flat urban routes, though riders dealing with sustained hills or longer commutes might find themselves wishing for gears. The single speed does mean less fiddling around in traffic, and the mechanical brakes give you direct, straightforward stopping power.

This bike suits commuters juggling cycling with public transport, or anyone working from home a couple of days a week who wants an easy-to-store electric option for short journeys. The fold and compact size make it practical for mixed-mode commuting, and the electric assist takes the sweat out of a morning ride. Riders after a sporty experience or those covering serious distances might look elsewhere, but for urban stop-start cycling where convenience and portability matter, the A1F covers the basics well.
