Description

The Chamrider DM427 Electric Bike is a capable everyday Electric Bike built for commuting, delivery work, and weekend riding. With a powerful motor, extended electric range, and high load capacity, it’s designed for riders who need reliability, comfort, and performance for daily use and longer journeys.

High-Speed Motor Performance
Powered by a 750W high-speed motor, the DM427 delivers strong acceleration and confident cruising performance. With a top speed of up to 50 km/h, it’s well suited to longer commutes and efficient urban travel where permitted.

Extended-Range Battery System
The 48V 27Ah battery provides an impressive electric-only range of 60–90 km, depending on riding conditions and load. This larger capacity battery makes the DM427 ideal for delivery riders and commuters who need dependable all-day range without frequent charging.

Stable Ride & Confident Control
Fitted with Chaoyang 27.5″ × 2.35″ tyres, the DM427 offers a balanced ride with good rolling efficiency and grip on roads and cycle paths. A hydraulic brake system with power cut-off delivers strong, controlled stopping power, improving safety at higher speeds and under load.

Versatile Gearing for Everyday Riding
A 7-speed drivetrain allows smooth gear changes and flexible riding across flat routes, hills, and stop-start traffic, helping maintain efficiency and rider comfort throughout the journey.
