Buying DYU online?
As with a car, ask where you can take your ride if it needs a repair.
Be cautious if a seller can’t give you a local workshop address, especially if they ship from overseas or dropship.
Check with the brand that the seller is authorised and ask who handles warranty repairs.

Zip Through the City
The D3F’s quiet 250 W motor delivers smooth acceleration the moment you twist the throttle or tap into one of three pedal‑assist levels. Perfect for quick errands or weaving through traffic, it feels almost like riding on air.
Pocket‑Sized Power
Despite its petite 14″ wheels and minimalist frame, the D3F hides a 36 V 7.8 Ah battery that slides out for charging in under 4 hours. On a full charge, you’ll cover up to 40 km in pure electric mode—or stretch that to 60 km when you add a little pedal power.
Comfort in a Small Package
Rugged puncture‑resistant tires and a spring‑loaded saddle soak up bumps you’d never expect to feel on such a tiny bike. Your joints—and your morning coffee—thank you when you sail over cracks, cobblestones, or speed bumps without a jolt.
Folds in a Flash
One quick release on the stem and frame hinge collapses the D3F into a footprint small enough for bus racks, train floors, and office nooks. At just 18 kg, it’s light enough to carry upstairs or stash under your desk.
Safety You Can Count On
Front and rear LEDs keep you visible at dusk, while mechanical disc brakes deliver confident stopping power in rain or shine. Reflective accents around the frame give you that extra edge in low‑light conditions.

Feel the surge of smooth, efficient acceleration as the DYU D3f’s advanced 250 W hub motor delivers instant torque—hitting a regulated 25 km/h top speed without rattling your ride. Sealed for durability and tuned for maximum range, it’ll carry you up hills and through traffic with effortless confidence.
Ride with total peace of mind thanks to precision‑engineered disc rotors on both wheels. High‑sensitivity calipers bite instantly in all weather conditions, giving you razor‑sharp modulation and the shortest stopping distances—perfect for urban commutes and crowded streets.
From the bright LED headlight and spring‑loaded comfort saddle to the tactile bell and easy‑reach throttle, the D3f packs essential features seamlessly into its compact chassis. A built‑in rear fender keeps you dry, while the discreet carry handle doubles as a battery hatch for grab‑and‑go recharging.
