DYU M20

What the DYU M20 is built for

The DYU M20 is an electric mountain bike for trails and off-road riding.

It has a 250 W (1,000 W peak) motor and a top speed of 25 mph (40 km/h).

It carries a 874 Wh battery and a stated range of up to 100 miles (161 km) on a charge. Real-world range is usually lower than the rated figure: it falls with throttle use, hills, cold weather, rider weight and higher assist levels.

The DYU M20 weighs 88 lb (40 kg), carries up to 265 lb (120 kg) including the rider and is rated IP54 against water.

In the United States the DYU M20 sells for $899, below the median of $1,299 across 22 electric mountain bikes with a US price, among the more affordable models. That is $1 per watt-hour of battery.

Where the DYU M20 may be ridden

In the European Union and the United Kingdom an e-bike counts as a bicycle only within the pedelec limits; as specified, its 25 mph (40 km/h) top speed is above the 25 km/h at which assistance must stop and its throttle moves it without pedalling, which the pedelec rules allow only as start-up help at walking pace. A model above those limits is treated as a moped there, with type approval, registration and insurance, unless the brand sells a version set to the European limits.

DYU M20 safety certification

The brand's listing for the DYU M20 does not state a UL 2849 or EN 15194 certification. New York City allows only e-bikes certified to UL 2849 to be sold or rented there, and California requires certified batteries from 2026; ask the seller for the certificate before buying.
