Long-Range Confidence That Changes How You Ride
The BK28 is built for riders who don’t want every journey to revolve around battery levels. With its 48V 25Ah removable battery, it delivers the kind of range confidence that suits longer commutes, countryside rides and unplanned detours. You spend less time thinking about when to charge and more time enjoying the ride itself. It is not just about distance on paper — it is about riding further with fewer limitations and more flexibility in everyday use.
Built for Hills, Not Just Flat Cycle Paths
Many e-bikes feel fine on smooth city routes, but start to struggle when the road turns steep or uneven. The BK28 is designed with hilly environments in mind, offering a more stable and controlled ride when climbing or dealing with inconsistent road surfaces. Whether it is a daily uphill commute or a longer route through mixed terrain, it gives you the confidence to keep going without second-guessing the bike.
A More Stable and Comfortable Ride Feel
The combination of fat 20×4.5 puncture-resistant tyres, front and rear suspension, and a solid aluminium frame creates a ride that feels noticeably more planted. Instead of being knocked around by potholes or rough patches, the bike absorbs more of the impact and keeps you balanced. The result is a ride that feels calmer, more controlled and less tiring over time, especially on longer journeys.
Hydraulic Braking That Builds Real Confidence
Tektro hydraulic disc brakes give the BK28 a more dependable stopping feel, particularly on wet roads or downhill sections. Braking is smoother, more responsive and easier to control compared to basic systems, which makes a real difference in everyday riding. On a heavier all-terrain e-bike, that added confidence is not just a bonus — it is essential for feeling safe and in control.
Practical Features That Make Daily Use Easier
The BK28 is designed to be lived with, not just ridden occasionally. A removable battery makes charging more flexible whether at home or work, while NFC unlock and app connectivity add a layer of convenience to everyday use. The front light improves visibility for evening rides, and the 5–6 hour charging time keeps downtime manageable. Altogether, it is a setup that fits into daily life without extra hassle.
Range Confidence That Changes the Ride
This is not about a number on a screen; it is about leaving with a much stronger sense that the bike can handle longer days, steeper routes and less predictable riding. The 48V 25Ah battery is the backbone of the BK28’s value, because it reduces the feeling of having to “plan around the battery” and lets the rider think more about where to go next.
Hydraulic Braking for Real-World Control
When the road gets wet, steep or uneven, stopping power is not a detail; it is part of how safe and in control the bike feels. Tektro hydraulic disc brakes give the BK28 a more confident braking character, especially for heavier riders or routes with sudden descents.
Comfort That Makes Rough Roads Less Punishing
Front and rear suspension help the BK28 smooth out the kind of surfaces that make a standard city e-bike feel harsh and busy. It is especially useful on mixed routes where the road quality changes from section to section, because the bike stays more composed and less fatiguing to ride.
A Practical, Thought-Through Setup
NFC unlock, app pairing, fast charging and a multifunction display make the BK28 feel easier to live with day to day. It is not just a ride machine; it is a bike designed to be used, charged and locked/unlocked without unnecessary friction.
Features And Details
Walk Assist Support
Walk assist mode provides gentle powered support when pushing the bike uphill or through tight areas. Particularly useful given the bike’s weight, making handling off the saddle more manageable.
Integrated Front Light
A built-in front light improves visibility in low-light conditions, helping you stay seen on darker lanes and early evening rides. Designed for practical everyday use rather than occasional add-ons.
Multifunction Display
A clear, easy-to-read display keeps essential ride data visible at a glance, helping you stay informed without distraction. Designed for real riding conditions rather than static showroom use.
Comfort-Focused Saddle
A wide, soft saddle (17.3 × 5.9 inches) is designed to support longer rides with less pressure and discomfort. It makes a noticeable difference on rough surfaces where ride comfort becomes more demanding.
NFC Unlock
Tap to unlock and get moving without keys or complicated steps. NFC access keeps everyday use simple while adding an extra layer of security for riders who park in shared or public spaces.
20×4.5 Puncture-Resistant Tyres
Wide fat tyres improve grip and stability across loose, uneven and broken surfaces. The puncture-resistant build adds reassurance for longer rides where reliability matters just as much as comfort.
Hydraulic Disc Brakes
Hydraulic braking delivers more controlled stopping with less effort at the lever. Particularly useful on wet roads, downhill sections and heavier bikes, where consistent braking feel makes a noticeable difference.
