Range Confidence That Supports Real Use
The BK28 is built for riders who want fewer limitations in everyday riding. With its 48V 25Ah removable battery (1200Wh), it provides the capacity needed for longer distances, varied terrain and higher assist levels. Instead of planning every ride around battery range, riders can focus more on where they want to go. This makes it suitable for commuting, longer trips and mixed-use scenarios without constant charging concerns.
Designed for Slopes and Mixed Terrain
Many e-bikes perform well on flat roads but feel less stable on slopes or uneven surfaces. The BK28 is designed to handle hills, rough roads and changing terrain with more consistency. It provides a more controlled ride when climbing or navigating less predictable routes, making it a practical option for riders who do not want to limit themselves to smooth urban environments.
Stable and Controlled Riding Experience
The combination of fat tires, suspension and a solid aluminium frame results in a more stable ride. Road vibrations and impacts are reduced, helping the rider stay balanced and comfortable. This improves control on longer rides and reduces fatigue, especially when riding on imperfect road surfaces.
Reliable Braking for Everyday Safety
Tektro hydraulic disc brakes provide more predictable and responsive braking performance. This is particularly important on wet surfaces, downhill sections or in urban traffic situations. The system allows smoother braking control and requires less effort, improving overall safety and rider confidence.
Practical Features That Improve Usability
The BK28 integrates features that make everyday use more convenient. A removable battery allows flexible charging, while NFC unlock and app connectivity simplify operation. The integrated front light improves visibility, and fast charging reduces downtime. Together, these features make the bike easier to use on a daily basis.
A Practical Setup for Everyday Use
The BK28 is designed with usability in mind. NFC unlock, app connectivity, fast charging (5–6 hours) and a multifunction display all contribute to a smoother day-to-day experience. It is a setup built for regular use, not just occasional riding.
Hydraulic Braking for Better Control
On wet roads, slopes or uneven surfaces, braking performance becomes critical. Tektro hydraulic disc brakes provide more consistent stopping power and smoother modulation, helping riders maintain control with less effort. This is particularly important for heavier bikes and real-world riding conditions.
Stable Ride Across Mixed Surfaces
The combination of 20×4.5 puncture-resistant fat tires, front and rear suspension, and an aluminium frame delivers a more stable riding experience. The bike absorbs road imperfections more effectively, helping maintain balance and control across rough or inconsistent surfaces.
Range Confidence for Longer Rides
This is not just about a number on a display. It is about having a battery system that supports longer distances, steeper routes and less predictable riding conditions. The 48V 25Ah (1200Wh) battery is a key part of the BK28’s value, reducing the need to constantly think about charging and allowing more flexibility in daily and weekend use.
Features And Details
Walk Assist Support
Walk assist provides low-speed motor support (up to 6 km/h) when pushing the bike. Particularly useful on slopes or when manoeuvring in tight spaces, helping manage the bike’s weight more easily.
Comfort-Focused Saddle
A wide and supportive saddle (44 × 15 cm) improves comfort on longer rides and uneven surfaces, reducing pressure and fatigue over time.
Multifunction Display
A clear display shows key riding information at a glance, including speed, assist level and battery status, allowing better control without distraction.
Integrated Front Light
A built-in front light improves visibility in low-light conditions, increasing safety on darker roads and evening rides. Designed as a practical, always-available feature
NFC Unlock System
NFC unlock allows quick and simple access without traditional keys, improving convenience while adding an extra layer of security.
20×4.5 Puncture-Resistant Fat Tires
Wide tires improve grip and stability across loose or uneven surfaces. The puncture-resistant construction adds reliability, especially for longer rides.
Hydraulic Disc Brakes
Hydraulic braking ensures consistent stopping performance with less force required at the lever, particularly useful on slopes and in wet conditions.
