DYU M20 Fat Tyre Electric Bike – 48V 18.2Ah and Full Suspension
The DYU M20 electric bike combines a distinctive long-saddle design with a substantial all-terrain build for adult riders who want fat-tyre stability without stepping outside the UK EAPC category. Its UK configuration uses a 250W continuous-rated rear-hub motor, electrical assistance limited to 15.5mph / 25km/h and a removable 48V 18.2Ah (873.6Wh) battery.
Full suspension combines a front fork with twin rear shocks, while 20 × 4-inch fat tyres add stability and grip on mixed surfaces. Dual-actuated mechanical disc brakes, Shimano 7-speed gearing, front and rear lighting, an LED display and fitted mudguards complete a practical package for commuting, leisure and longer mixed-surface rides.

Frequently Asked Questions
Is the DYU M20 road legal in the UK?
Yes. The UK-specification M20 is a 250W EAPC with assistance limited to 15.5mph / 25km/h. Riders must be 14 or over, and the original factory configuration must remain unchanged for public-road use.
What range can the DYU M20 achieve?
Estimated pedal-assist range is up to 100km (62 miles) under favourable conditions. Load, assistance mode, speed, gradients, surface, weather, tyre pressure and battery condition all affect real-world range.
Is the battery removable, and how long does charging take?
Yes. The 48V 18.2Ah battery is removable and secured with a keyed lock. A full charge takes approximately 7–8 hours. Charge in a dry, ventilated place using compatible equipment in good condition.
Does the DYU M20 fol over?,
No. The M20 has a non-folding aluminium frame and weighs 40kg. Its full-suspension chassis, long saddle and 20 × 4-inch tyres prioritise a substantial, stable ride rather than compact storage.
