Shimano 21-Speed Drivetrain
The Hailong One uses a 3 × 7 Shimano drivetrain, giving it 21 mechanical gears. This broad gearing range makes it much more mountain-bike focused than FAFREES' typical single-chainring city bikes.

The Fafrees 26 Hailong One Electric Mountain Bike is a straightforward 26-inch e-MTB with a 36V 13Ah removable battery, 250W continuous rear hub motor and versatile 21-speed gearing.
An 80mm suspension fork, 26×2.1-inch CST tyres and mechanical disc brakes give the Hailong One a practical setup for leisure riding, mixed routes and everyday use.
UK road-use note: Manufacturer-listed configuration uses a 250W continuous motor and a 25 km/h assistance limit. UK EAPC eligibility depends on the exact supplied configuration meeting current UK requirements.
Range and performance figures are manufacturer estimates. Actual results vary with rider weight, terrain, weather, tyre pressure, load and assistance level.

The Hailong One uses a 3 × 7 Shimano drivetrain, giving it 21 mechanical gears. This broad gearing range makes it much more mountain-bike focused than FAFREES' typical single-chainring city bikes.
An 80mm lockable suspension fork helps absorb impacts on trails, gravel paths and damaged roads. The lockout also allows the suspension to be firmed up when riding on smoother surfaces.
Its step-over aluminium frame and 26 × 2.1-inch tyres give the Hailong One the familiar geometry and handling of a traditional mountain bike rather than a folding or low-step commuter.
