Product Description
Folding Electric Fat Bike for Daily Rides and Varied Terrain
The BK6SPRO is a 20-inch folding electric Fat Bike designed for daily commuting, leisure rides and cycling across varied surfaces.
Its aluminium alloy folding frame combines convenient storage with wide 20 × 4.0-inch Fat Bike tyres, hydraulic disc brakes, front suspension and a 7-speed drivetrain for practical everyday riding.
Removable 48V 18Ah Battery – Up to 140 km Range
The BK6SPRO is equipped with a 48V 18Ah lithium-ion battery with 864Wh capacity.
Depending on rider weight, terrain, temperature, road conditions and riding style, the reference range is approximately 70–140 km.
The battery can be removed for convenient charging at home or at work. Charging takes approximately 6 hours with the 54.6V / 3A charger.
20 × 4.0-Inch Fat Bike Tyres
The wide 20 × 4.0-inch pneumatic Fat Bike tyres provide a larger contact area with the ground, helping improve grip and stability across different surfaces.
They are suitable for city roads, cycle paths, gravel tracks and light uneven terrain, while their wider profile also helps reduce vibrations during everyday riding.
Hydraulic Disc Brakes for Controlled Braking
The BK6SPRO features hydraulic disc brakes for responsive and progressive braking.
The hydraulic system provides controlled stopping performance during city riding, descents and changing road conditions, while requiring less hand effort than conventional mechanical braking systems.
Front Suspension for Added Comfort
The front suspension fork helps absorb shocks and vibrations from rougher roads and uneven surfaces.
Combined with the wide Fat Bike tyres, it provides additional comfort during longer journeys and mixed-surface riding.
250W Motor with Assistance up to 25 km/h
The 250W brushless motor provides pedal assistance at speeds of up to 25 km/h.
The electric assistance supports daily commuting, leisure journeys and moderate gradients while maintaining straightforward pedal-assisted operation.
7-Speed Drivetrain
The BK6SPRO features a 7-speed drivetrain, allowing riders to select a suitable gear according to gradient, road conditions and riding speed.
The different gears provide greater flexibility for flatter roads, moderate climbs and longer leisure rides.
Folding Aluminium Frame
The folding aluminium alloy frame reduces the space required for storage and transport.
With folded dimensions of approximately 940 × 500 × 750 mm, the BK6SPRO can be stored more easily at home, in an office, garage or vehicle.
LCD Display and Front Light
The multifunction LCD display provides key riding information such as speed, battery status and assistance information.
The front light helps improve visibility during lower-light riding conditions, adding practicality for everyday commuting.
IP54 Protection Rating
The BK6SPRO has an IP54 protection rating, providing protection against limited dust ingress and water splashes during normal everyday use.
Avoid submerging the bike or using a high-pressure washer directly on electrical components.
