Description
Powered by a 750W brushless high-speed motor, the Chamrider DTS425 delivers smooth acceleration and dependable torque for urban riding and heavier loads. With a top speed of up to 45 km/h, it provides confident performance for longer commutes and efficient delivery use where permitted.
High-Capacity Battery Options
The 48V 25Ah battery offers strong everyday range, with higher-capacity options up to 32Ah available on some listings for riders who need extended distance or longer working days. This flexible battery setup makes the DTS425 suitable for both regular commuting and more demanding usage.
Stability, Grip & Comfort
Wide CST 20″ × 4.0″ fat tyres deliver excellent grip and stability on tarmac, cycle paths, and rougher urban surfaces. The fat-tyre setup improves comfort and control, especially when riding with added weight or on uneven ground.
Confident Braking & Control
A hydraulic brake system provides strong, reliable stopping power in all conditions, helping maintain confidence when riding at speed or carrying loads. A 7-speed drivetrain allows smooth gear changes and flexibility across hills, flats, and stop-start traffic.
Smart Display & Ride Features
The 48V LCD display keeps essential ride data clearly visible, with 1–5 pedal assist levels and cruise control to tailor performance, manage energy use, and reduce fatigue on longer rides.
