This Bike Is Not Road Legal. Private Land Use Only.
This bike cannot be ridden on public roads, pavements, or cycle paths in the UK. Its motor output and assisted top speed exceed the legal limits set by the UK Electrically Assisted Pedal Cycle (EAPC) regulations, which cap electric bikes at 250W motor power and 15.5 mph (25 km/h). Because this bike exceeds both thresholds, it is classified as a motor vehicle and would require registration, insurance, and a valid licence to use on public roads. This bike is designed exclusively for use on private land such as farms, estates, and off-road tracks where road traffic law does not apply.
See UK LegislationYour daily commute, minus the hassle
The DYU D3F folding electric bike is for anyone who wants to glide through UK city streets without sweating on the bus or paying for parking. Its 250W motor and 15.5 mph assisted speed keep you within UK road law, while the 14-inch tyres and folding frame make it easy to store in a hallway or take on a train. If you need a reliable, legal, and compact way to get around town, this bike earns its place.
Power that respects UK road law
The DYU D3F uses a 250W motor that peaks at 500W, giving you confident acceleration from traffic lights and steady climbing on gentle hills. It assists up to 15.5 mph, exactly the UK legal limit for e-bikes, so you can ride on roads and cycle paths without registration or insurance. The motor is quiet and smooth, making every journey feel effortless.
Go up to 25 miles on one charge
The 36V 10Ah lithium battery gives you up to 25 miles of throttle-only riding, or up to 31 miles with pedal assist. That covers most UK commutes, trips to the shops, or a leisurely ride along a canal towpath. A full charge takes about 5 hours, so you can plug in at work and be ready for the ride home.
Comfortable on bumpy city streets
The DYU D3F is built for everyday comfort, with 14-inch tyres that soak up cracks and potholes better than solid wheels. The upright riding position keeps your back relaxed, and the padded saddle supports you on longer trips. At 42 lbs, the bike is light enough to carry up a flight of stairs or lift into a car boot.
Stop safely in any weather
Front and rear disc brakes give you strong, predictable stopping power, even when the road is wet from a typical British drizzle. The brakes are easy to modulate, so you can slow smoothly in traffic or stop quickly if a pedestrian steps out. With an IP54 waterproof rating, the bike shrugs off light rain and puddle splashes.
Simple controls and useful extras
The DYU D3F keeps things straightforward: a clear display shows your speed and battery level, and the controls let you switch between pedal assist and throttle. Cruise mode holds a steady speed on long, open stretches, reducing hand fatigue. A bright headlight and rear fog light help you see and be seen on dark winter evenings.
Folds small, rides big
The DYU D3F folds down to just 46 by 8 by 28 inches, so it tucks neatly into a hallway cupboard, under a desk, or in the boot of a small car. The metal frame is sturdy enough for riders up to 265 lbs, yet the bike remains easy to carry. In the box you get the bike, battery, charger, and the tools needed for simple assembly.
