DYU M20 All-Terrain Long-Range Electric Bike

The DYU M20 All-Terrain Electric Bike combines a large-capacity battery, 20-inch fat tyres and full-suspension comfort in a distinctive motorcycle-inspired design built for longer rides and mixed terrain.

Powered by a 250W rated motor and a substantial 48V 18.2Ah removable lithium-ion battery, the M20 delivers smooth electric assistance up to 25km/h (15.5mph) while giving riders the battery capacity needed for commuting, leisure riding and longer weekend adventures.

Its 20" × 4.0" fat tyres provide a stable, confidence-inspiring ride across tarmac, gravel and uneven tracks, while the front suspension fork and twin rear shock absorbers help reduce bumps and vibration. Shimano 7-speed gearing gives you more control over changing terrain, with dual-actuated mechanical disc brakes providing dependable stopping performance.

The M20 is also one of DYU's most substantial long-range e-bikes. Its 873.6Wh battery can be removed for convenient indoor charging, while DYU advertises a maximum range of up to 100 miles under ideal riding conditions.

With its long padded saddle, integrated lighting and rugged fat-tyre stance, the DYU M20 electric bike is an excellent choice for riders looking for a comfortable, powerful-feeling and versatile e-bike for everyday journeys and exploring further afield.

Assembly

The DYU M20 is delivered partially assembled and requires some final assembly and safety checks before riding.

This may include fitting or aligning components such as the handlebars and pedals and checking the brakes, wheels, tyre pressures, electrical connections and all fixing points.

All components should be checked carefully before the first ride. If you are not confident completing the assembly or safety checks yourself, we recommend having the bike inspected by a qualified bicycle or e-bike technician.

Important UK Road Use Information

The UK DYU M20 is listed with a 250W continuous rated motor and assistance limited to 25km/h (15.5mph). DYU also advertises an electric/pure-electric riding mode.

In Great Britain, an e-bike must meet EAPC requirements to be treated in the same way as a conventional bicycle. A bike capable of being propelled without pedalling above 6km/h generally requires appropriate type approval. Riders should ensure the configuration being used complies with applicable UK regulations when riding on public roads and cycle routes.
