Product Description
BK28 – Electric Fat Bike for All-Terrain and Outdoor Riding
The BK28 is a 20-inch electric Fat Bike designed for riders looking for greater stability, comfort and control across a variety of surfaces.
With extra-wide 20 × 4.5-inch Fat Tyres, front and rear suspension, Tektro hydraulic disc brakes and a removable high-capacity battery, the BK28 is suitable for daily commuting, leisure riding, gravel roads, countryside paths and uneven terrain.
20 × 4.5-Inch Fat Tyres for Grip and Stability
The extra-wide 20 × 4.5-inch Fat Tyres provide a large contact area with the ground, helping improve grip, stability and riding confidence.
Their wide profile makes the BK28 particularly suitable for riding across:
Urban roads
Gravel tracks
Countryside paths
Dirt roads
Rough tracks
Light uneven terrain
The pneumatic tyres also help absorb vibrations from rougher surfaces for a more comfortable riding experience.
Removable 48V 25Ah Battery – Up to 100 km Range
The BK28 is equipped with a removable 48V 25Ah lithium-ion battery with 1200Wh capacity.
It provides a reference pedal-assisted range of approximately 80–100 km per charge, depending on riding conditions.
The battery can be removed from the bike for convenient charging at home or at work.
A 4A charger is included for practical everyday charging.
Full Suspension for Greater Riding Comfort
The BK28 features front and rear suspension to help absorb shocks and vibrations when riding over uneven surfaces.
The full-suspension system provides additional comfort and control on gravel roads, rough tracks and other mixed-terrain routes, particularly during longer journeys.
Tektro Hydraulic Disc Brakes
Front and rear Tektro hydraulic disc brakes provide progressive and controlled braking performance.
Hydraulic braking requires less hand effort than conventional mechanical systems and provides precise braking control when riding downhill, on wet surfaces or across more demanding terrain.
7-Speed Drivetrain
The 7-speed drivetrain allows riders to select a suitable gear for different terrain and riding conditions.
Combined with electric pedal assistance, it provides additional flexibility for urban riding, leisure journeys, moderate climbs and mixed-terrain routes.
5 Assistance Levels
The BK28 offers 5 pedal-assistance levels, allowing riders to adjust the amount of electric assistance according to terrain, distance and riding preference.
A 6 km/h walk-assist mode is also available, helping when pushing the heavier Fat Bike on foot or manoeuvring it on slopes.
NFC, Bluetooth and Mobile App
The BK28 combines practical riding equipment with smart connectivity.
Available functions include:
NFC unlocking
Bluetooth connectivity
Mobile App control
Bike locking and unlocking
Assistance adjustment
Ride recording
Battery monitoring
Light control
GPS navigation
These functions provide additional convenience for commuting and everyday use.
Multifunction LCD Display
The multifunction LCD display provides key riding information at a glance, allowing riders to monitor important information while travelling.
Strong Construction for Everyday and Outdoor Use
The BK28 is designed to support a maximum load of 120 kg.
Its combination of wide tyres, full suspension and hydraulic brakes makes it particularly suitable for riders looking for an electric bike capable of handling both everyday journeys and more varied terrain.
