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 All-Terrain Companion for UK Adventures
The DYU FF500 is built for riders who want one bike that can handle the morning commute, a weekend ride along the canal towpath, and a quick trip to the shops. With 20-inch fat tyres and a folding frame, it grips everything from wet city streets to gravel bridleways while still fitting in a car boot or hallway cupboard. If you need a dependable, go-anywhere e-bike that won't take over your flat, the FF500 is worth a serious look.

Powerful Motor for Steady UK Climbs
You'll feel confident tackling hills and headwinds thanks to the DYU FF500's 500W high-speed motor. It delivers smooth, responsive assistance up to the UK legal limit of 15.5 mph, so you can keep pace with traffic without breaking a sweat. The motor is rated for a 15-degree uphill grade, making it a practical choice for routes through hilly towns like Sheffield or Bristol.

Long-Lasting Battery for Daily Rides
Plan your week without worrying about running out of charge: the FF500's 48V 14Ah removable battery gives you up to 43 miles on a single charge. That's enough for a full week of short commutes or a long Sunday ride through the South Downs. The battery is removable, so you can charge it indoors at your desk or in the kitchen, and it takes 7-8 hours to go from empty to full.

Comfortable Ride on Any Surface
The DYU FF500 smooths out rough roads and paths with its front suspension and 20 × 4-inch fat tyres. These wide tyres act like a cushion, absorbing bumps from potholes, cobbles, and tree roots, while the suspension fork takes the sting out of kerbs and speed bumps. You'll arrive at your destination feeling fresh, even after a long ride on mixed terrain.

Reliable Stopping Power in Wet Weather
Stay safe on rainy UK roads with the FF500's disc brakes, which provide strong, predictable stopping power in all conditions. Unlike rim brakes, they perform consistently even when the rims are wet or muddy, giving you confidence on steep descents and busy junctions. The bike's IP54 waterproof rating means light rain and puddle splashes won't stop you from riding.

Clear Display and Easy Gear Changes
Keep track of your speed, battery level, and distance with the FF500's multi-functional LED display. It's bright enough to read in daylight and gives you the information you need at a glance. The Shimano 7-speed derailleur lets you find the right gear for any situation, whether you're climbing a hill or cruising along a flat cycle path.

Folding Frame for Easy Storage and Transport
The DYU FF500 folds down quickly, making it a smart choice if you live in a flat, commute by train, or have limited storage space. When folded, it's compact enough to tuck into a hallway, under a desk, or in the boot of a small car. Despite its sturdy build, it weighs 68 lbs, so you can lift it into a car or carry it up a few steps without too much effort.
