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.
See UK LegislationYour all-rounder for commutes and adventures
The ChamRider DM427 is built for UK riders who want one bike that does it all—daily commutes, weekend trail rides, and even delivery work. With a powerful 750W motor, a 27Ah battery that delivers up to 62 miles of range, and a top speed of 31.1 mph, it’s a versatile e-bike that keeps up with your busy life. Whether you’re weaving through city traffic or exploring gravel paths, this bike offers dependable performance and a smooth ride.
Powerful 750W motor for steep hills
Climb confidently with the ChamRider DM427’s 750W rear hub motor, which produces 92 Nm of torque. It’s designed to handle steep gradients and quick acceleration, making light work of hilly commutes or loaded delivery runs. The motor is paired with a 48V 25A controller for responsive power delivery, so you can tackle varied terrain without breaking a sweat.
Long-range 27Ah battery for extended rides
Go further on a single charge with the 48V 27Ah battery, which provides up to 62 miles of range. Whether you’re commuting across town or enjoying a long weekend ride, you won’t have to worry about running out of power. The battery is removable, so you can charge it indoors or swap in a spare for non-stop riding.
Comfortable ride with front suspension and wide tires
Enjoy a smooth and stable ride thanks to the locked front fork and 27.5-inch Chaoyang tires. The suspension absorbs bumps on rough roads, while the wide tires provide excellent grip on both tarmac and light trails. The ergonomic saddle and adjustable handlebar stem let you find the perfect riding position for long journeys.
Hydraulic brakes for reliable stopping power
Stay safe in all conditions with the ChamRider DM427’s hydraulic brake system, which delivers strong and consistent stopping power. The brakes also feature a power-off function that cuts motor assistance when you brake, adding an extra layer of safety. Whether you’re riding in wet weather or descending a hill, you can stop with confidence.
Clear LCD display and 7-speed gearing
Keep track of your ride with the central LCD display, which shows your speed in mph, battery level, and gear setting. The display includes cruise control and a 1–5 gear assist system, letting you tailor the motor’s output to your needs. The 7-speed Shimano derailleur gives you precise control over your pedalling effort, making it easy to find the right gear for any situation.
Durable aluminium frame for everyday use
The ChamRider DM427 is built to last with a thickened aluminium alloy frame that supports up to 397 lbs. It’s designed for the demands of daily riding, from potholed city streets to light off-road trails. The bike comes with a headlight and horn for visibility and safety, plus a rear rack for carrying cargo or panniers.
