DYU C9 Key Features

Quick Summary
The DYU C9 20″ Long-Range Electric Bike is a premium foldable eBike designed for city commuting, touring, and everyday adventure. Combining an efficient 250 W motor with a high-capacity 48V 15.6Ah removable battery, it delivers an impressive range that can reach up to 150 km on pedal-assist and a smooth, responsive ride that’s perfect for urban streets and light off-road paths.

Smooth & Responsive Power
The brushless 250 W motor provides dependable pedal support up to the legal UK/EU top speed of 25 km/h, while the wide 20″ tyres and shock-absorbing frame deliver a comfortable ride on surfaces from paved roads to gravel paths.

Long-Range Battery Performance
With its large 15.6 Ah battery pack, the C9 is built for long journeys and daily commuting without constant recharging. Real-world ride distances can vary depending on assist level, terrain, and rider weight, but the efficient battery system pushes this model into the long-range category for foldable eBikes.

Comfort & Control
Hydraulic disc brakes provide strong, consistent stopping power in varied conditions, while the ergonomic frame geometry and suspension components smooth out bumps for a more enjoyable ride. The LCD display gives clear visibility over speed, battery level, and assist mode at a glance.
