The HITWAY BK15 4.0 is a versatile fat-tyre electric bike built for comfort, stability, and everyday usability. Powered by a 250W rear hub motor and a large 48V 15.6Ah removable battery, it combines long-range capability with confident handling thanks to oversized 26″ × 4.0″ tyres. With NFC unlocking, mobile app connectivity and a robust frame design, the BK15 is ideal for commuting, leisure riding and light off-road exploring.
Whether cruising through town or tackling mixed surfaces, the BK15 delivers smooth pedal assistance, excellent grip, and a comfortable upright riding position suitable for a wide range of riders.
The efficient 250W brushless rear motor provides pedal assistance up to 25 km/h (15.5 mph), keeping the BK15 fully compliant with UK EAPC regulations. The motor offers responsive support for daily commutes and gentle inclines, while the Shimano 7-speed drivetrain gives flexibility across varied Terrain.
Equipped with a high-capacity 48V 15.6Ah lithium-ion battery, the BK15 offers an estimated 55–95 km of riding depending on rider weight, Terrain, temperature and assistance level. The battery is fully removable for secure indoor charging and typically recharges in 6–7 hours.
The standout feature of the BK15 is its oversized 26″ × 4.0″ fat tyres, providing superb traction, cushioning and stability across tarmac, gravel, grass and light trails. A front suspension fork helps absorb bumps and ensures a smoother ride on uneven surfaces.
A clear LCD provides essential riding information, including speed, PAS level, battery status and distance. Integrated front lighting improves low-light visibility, while intuitive controls make the bike easy for both new and experienced riders.
Mechanical disc brakes, front and rear, offer consistent stopping power in various weather conditions. The BK15's reinforced frame is designed for durability and stability, while its geometry provides a comfortable upright posture suitable for longer rides.
The BK15 includes NFC smart unlocking for quick, secure access, along with mobile app connectivity for monitoring ride data, adjusting settings, and enhancing security. The removable battery allows safe indoor charging, and the strong frame ensures reliability for daily use.
A 48V charger with a UK plug is included for safe and efficient charging. A full charge typically takes 6–7 hours, depending on the battery's condition and charging conditions.
