Responsive power for city and hills

The high-speed brushless motor delivers a smooth, quiet boost that helps you reach the UK legal limit of 15.5 mph without breaking a sweat. With 250 W of assistance, you can glide up inclines of up to 15°, making light work of steep urban streets or countryside bridleways.

Go further on a single charge

A generous 36 V 10 Ah battery gives you a real-world range of 22 to 25 miles, perfect for daily commutes or leisurely weekend rides along UK cycle paths. When it’s time to top up, a full charge takes just 4 to 5 hours, so you’re ready to go by morning.

Confident stopping in all conditions

Dual mechanical disc brakes front and rear give you reliable, sharp braking when you need it most, whether you’re navigating busy roundabouts or descending a damp hill. This setup ensures consistent performance, adding a layer of safety to every journey on UK roads.

Ride further with less effort

Enjoy a smoother, more responsive ride thanks to the intelligent speed sensor. It reads your pedalling pace and delivers power exactly when you need it, reducing strain on hills and headwinds. This smart assistance helps you cover more miles across town without arriving tired and sweaty.

Fold in seconds, go anywhere

The DYU D3F is built for true freedom on UK streets. One quick motion collapses it into a compact shape that tucks neatly into a hallway, under a desk, or beside you on the train. No need for a car rack or a garage — this bike fits into your life, not the other way round.

One bike fits the whole family

With a quick-adjust seatpost, riders from about 5 feet to 6 feet 3 inches can find their perfect position in moments. Share it between partners or grown-up kids without any tools or fuss. Even after adjusting, the folded size stays just as handy for storage.

Stay seen after sunset

Riding home on unlit lanes or through the city at dusk feels far safer with the built-in front and rear lights. Just press and hold the right button for three seconds to switch them on. You'll be clearly visible to traffic and pedestrians, making every evening journey more secure.

Power and range for daily rides

Enjoy a smooth, responsive ride with the 250W motor, perfectly compliant with UK road law. It easily tackles hills up to a 15° incline, so you won't be left pushing on steep city streets. The 36V 10Ah battery gives you a reliable 22–25 miles of assisted range, ideal for commutes or weekend trips. A full charge takes just 4–5 hours, ready for your next journey.

The bike's compact design makes storage effortless. When folded, it shrinks to just 46 by 8 by 28 inches, sliding into car boots or tight hallways. Unfolded, it measures 46 by 20 by 39 inches, with a stable 14-inch wheel setup. At only 40 lbs, it's light enough to carry onto public transport or up a flight of stairs.
