Built for Real-World Riding

The lightweight aluminium frame and dual front suspension soak up potholes and cobbles, while the 20-inch by 3.0-inch off-road tyres give you grip and stability on everything from city streets to gravel paths. A Shimano 7-speed drivetrain and hydraulic disc brakes put you in full control, and the bright LED headlight keeps you visible on dark evenings.

Powered by a 48V 15.6Ah battery, the C9 can cover up to 93 miles in pure electric mode on a single charge – plenty for a week of commuting or a long Sunday ride. The intelligent vector controller delivers smooth, responsive power, and the bike can handle loads up to 18 stone 12 lbs, with a charging time of around 8 hours.

Fold away in seconds flat

Transforming the DYU C9 for storage or transport is refreshingly simple. Just release the quick-release lever to lower the stem, tuck in the pedals, and use the frame's quick-release catch to fold it down. In three straightforward moves, you can stow it in a boot, carry it onto a train, or tuck it under your desk at work.

Confident handling on any surface

Generous 20-inch by 3.0-inch tyres soak up bumps from cracked tarmac and gravel tracks alike, while the front suspension fork smooths out the ride even further. The balanced placement of the motor and battery keeps the bike stable and planted, so you feel in control whether you're weaving through city traffic or venturing onto a woodland trail. An ergonomic frame geometry ties it all together, making every mile a pleasure.
