250W Brushless Motor

The FAFREES F28 MT is powered by a 250W brushless rear hub motor with up to 480W peak output and 45Nm of torque. This setup delivers smooth, responsive pedal assistance for everyday commuting, gradual hills, gravel paths and light trail riding. Because the motor is mounted in the rear wheel, power delivery feels stable and natural, helping the bike maintain momentum without making the ride feel overly aggressive. The brushless design also helps reduce maintenance while providing quieter and more efficient operation over longer journeys.

36V 15Ah Removable Battery

A 36V 15Ah / 540Wh removable lithium-ion battery gives the F28 MT a manufacturer-stated range of approximately 55–65 km (34–40 miles) depending on rider weight, terrain, assistance level, weather and riding style. The removable design makes charging more convenient, allowing the battery to be taken indoors and charged separately from the bike. It is well suited to daily commuting and longer leisure rides, offering a practical balance between capacity, weight and range without making the bike unnecessarily bulky.

100mm Front Suspension & 27.5 × 2.25" Tyres

The F28 MT uses a 100mm travel front suspension fork to help absorb bumps, vibrations and rougher surfaces, improving comfort and control on uneven roads, gravel tracks and light trails. Combined with 27.5 × 2.25-inch tyres, the bike provides a stable footprint with good grip while still rolling efficiently on paved surfaces. The larger wheel size also helps the bike carry momentum more smoothly over small obstacles, making the F28 MT a versatile choice for riders who want one bike for commuting, leisure riding and mixed-terrain use.
