HITWAY BK15 4.0 Fat Tyre Electric Bike 26 Inch 250W – Review

The HITWAY BK15 4.0 is a fat tyre electric bike designed for cyclists who want to ride equally well in town and on paths, uneven tracks or soft surfaces. With its 250 W hub motor, 70 Nm torque, removable 48 V 15.6 Ah (748.8 Wh) battery and 26 × 4.0 inch tyres, it prioritises stability, comfort and everyday versatility.

Who is this bike for?

This model is particularly suited for:

• Daily urban and suburban commutes
• Rides on paths, tracks, gravel and rough roads
• Cyclists seeking more stability thanks to wide tyres
• Users climbing slopes up to 25°
• People between 170 and 200 cm tall
• Weekend leisure trips on varied terrain

Performance and range

The BK15 4.0 features a 250 W hub motor delivering 70 Nm, designed to provide powerful and reassuring pedal assistance during starts, climbs and long rides. With a maximum assisted speed of 25 km/h, it remains compliant for road use across Europe whilst offering dynamic riding on everyday terrain.

• Claimed range: up to 120 km
• Maximum assisted speed: 25 km/h
• Climbing capacity: up to 25°
• Charging time: 6 to 7 hours

Its 48 V 15.6 Ah (748.8 Wh) lithium-ion battery is removable and fitted with a key anti-theft lock. It allows you to charge the bike easily at home or the office whilst securing it better during parking. This configuration suits both regular commutes and long weekend rides.

Design and comfort

The BK15 4.0 sits on a high-tensile steel frame and weighs 30.5 kg. Its format prioritises robustness and stability, especially on mixed routes where grip and riding confidence are paramount.

Its puncture-resistant 26 × 4.0 inch pneumatic tyres are one of its major strengths. They improve grip and comfort on rough asphalt, gravel paths, forest trails, sand or snow. The front suspension fork helps filter shocks and vibrations from cobblestones, road joints and uneven surfaces.

For braking, mechanical disc brakes front and rear ensure consistent stopping in various conditions. The Shimano 7-speed transmission makes it easier to adapt pedalling to terrain. The cockpit includes a multifunctional LCD display with app and NFC, plus NFC unlocking for more modern everyday use.

The bike also features a StVZO-approved front and rear LED lighting system, a wide adjustable-angle rear mudguard, and equipment designed for regular use. HITWAY also highlights a 2-year warranty and TÜV and CE certification.
