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.

The ChamRider DH420 is built for riders who want one electric bike that can handle the daily commute, a weekend blast along gravel paths, and light off-road trails. With a 750W motor, full suspension, and a 20Ah battery, it delivers the power and range to make every ride feel effortless. Whether you are dodging potholes on city streets or exploring bridleways in the Peak District, this bike is ready when you are.
Powerful 750W Motor for Steep Climbs
The ChamRider DH420’s 750W motor produces 98 Nm of torque, so you can tackle steep hills and rough ground without breaking a sweat. It reaches a top assisted speed of 31.1 mph, making light work of long stretches on open roads. The motor is paired with a 48V controller for smooth, responsive acceleration every time you twist the throttle.
Long-Range 20Ah Battery for All-Day Rides
With a 48V 20Ah battery, the ChamRider DH420 gives you up to 50 miles on a single charge, so you can commute all week or enjoy a full day out without worrying about running low. The battery is removable, making it easy to charge at home or in the office. A 4A fast charger tops it up in about 5 hours, so it is ready to go again by morning.
Full Suspension and Comfortable Geometry
The ChamRider DH420 smooths out rough roads and bumpy trails with a full suspension system, including an adjustable front fork and a rear shock absorber. The aluminium alloy frame and 27.5-inch tyres help absorb vibrations, while the ergonomic saddle and handlebar keep you comfortable on longer rides. Even after 30 miles, you will feel fresh rather than fatigued.
Hydraulic Brakes for Confident Stopping
Safety comes first with the ChamRider DH420’s hydraulic disc brakes, which deliver strong, reliable stopping power in wet or dry conditions. The brakes also cut power to the motor when you pull the lever, giving you extra control on steep descents. Whether you are riding in London traffic or on a muddy trail, you can trust these brakes to bring you to a halt quickly.
Clear LCD Display and Simple Controls
The ChamRider DH420 features a central LCD display that shows your speed in mph, battery level, and gear setting at a glance. You can switch between 1 and 5 levels of pedal assist, or use the throttle for a boost when you need it. The display also includes a cruise control function, making longer stretches of road more relaxing.
Durable Frame and Everyday Practicality
The ChamRider DH420 is built on a strong aluminium alloy frame with a maximum load capacity of 397 lbs, so it can carry you and your gear with ease. It comes with a rear rack, mudguards, and lights with a horn, making it practical for daily use in the UK’s changeable weather. The 9-speed gear system lets you find the right cadence for any situation, from climbing hills to cruising on the flat.
