Conquer 25° inclines effortlessly while maintaining perfect bike balance and center of gravity.
Reliable Hydraulic Braking for Safer Riding
The BK-U1 is equipped with hydraulic disc brakes, providing strong, smooth, and responsive stopping power in both dry and wet conditions.

Features and Details
Lockable Suspension Fork
Enjoy the high-performance suspension fork. Engage the shock absorption to smooth out bumpy cobblestones and uneven city streets for a "cloud-like" ride. When you hit smooth asphalt or need to climb efficiently, simply flip the lockout switch to maximize your pedaling power and speed.
Integrated Lighting System
Ride with confidence at any hour. The BK-U1 comes fully equipped with a powerful LED headlight to illuminate the path ahead and a rear tail light to ensure you are clearly visible to vehicles and pedestrians from behind. This integrated system provides 360-degree safety for early morning commutes and late-night adventures.
27.5" x 2.2" Puncture-Resistant Tires
Ride the city with confidence. These reinforced 27.5" × 2.2" puncture-resistant tires are about 26% wider than standard 1.75" city bike tires, providing improved stability and riding comfort. The increased air volume helps absorb road vibrations, while the wider contact surface delivers better grip on uneven asphalt and wet roads, making daily commuting smoother and more controlled.
Shimano 7-Speed Transmission
The trusted Shimano 7-speed gearing system allows you to adjust smoothly to changing road conditions and riding speeds. From city commuting to weekend rides, it provides reliable, low-maintenance performance and precise gear changes you can count on every day.
Adjustable Viewing Angle
Featuring a -30° to 30° adjustable stem, you can easily customise the handlebar position to suit your riding style. Enjoy a more comfortable, ergonomic posture for daily commuting and longer journeys alike.
Rear Cargo Rack
Transform your e-bike into a versatile daily hauler. The BK-U1 features a rear rack designed to carry your work bag, groceries, or weekend gear with ease. Its sturdy construction ensures a stable ride, even when fully loaded, making it the perfect replacement for your car on city errands.
