The Chamrider DH420 Electric Bike is a capable everyday Electric Bike designed for commuting, delivery work, and weekend riding. With a powerful motor, full suspension setup, and extended range, it’s built to handle longer journeys, varied terrain, and faster-paced riding while keeping comfort and control front and centre.
High-Speed Motor Performance
The DH420 is powered by a 750W high-speed motor, delivering strong acceleration and responsive performance across urban roads and mixed terrain. With a top speed of up to 50 km/h, it offers confident cruising and efficient travel where permitted.
Long-Range Battery System
A 48V 20Ah battery provides a practical electric-only range of 50–80 km, depending on riding conditions, terrain, and rider weight. This makes the DH420 well suited to longer commutes and full working days without constant recharging.
Full Suspension Comfort
Equipped with a full suspension system with DNM components, the DH420 absorbs bumps, uneven surfaces, and road imperfections with ease. This setup improves comfort and stability, especially on rough roads, paths, and longer rides.
Grip, Control & Braking
The Chaoyang 27.5″ × 2.8″ tyres offer excellent grip and a confident ride feel, balancing speed with stability. A hydraulic brake system with power cut-off ensures strong, controlled stopping power, even when riding at higher speeds or under load.
