More Riding Between Charges
Daily commuting, errands and weekend rides can quickly add up. With a removable 504Wh battery and up to 150 km of range under suitable conditions, the BK-U2 gives you more flexibility between charging stops.
Charge the battery on or away from the bike, then get back to riding without making battery percentage the centre of every journey.
Assistance That Feels Natural
Not every e-bike feels natural when the motor kicks in. The BK-U2 uses a torque sensor to respond to how hard you actually pedal, giving you smoother assistance when setting off, accelerating or climbing.
The result is a ride that feels easier without feeling disconnected — especially useful in stop-start city traffic and on longer journeys where comfort matters.
Smoother Across Everyday Roads
Cracked asphalt, uneven cycle paths and rougher suburban roads can make everyday riding tiring. Large 29 × 2.25in tyres roll more smoothly over surface changes, while 100mm front suspension helps absorb repeated bumps before they reach the rider.
The larger wheel size also gives the bike a more settled, stable character on longer rides.
Braking You Can Control
Busy junctions, downhill sections and changing road conditions demand more than just stopping power. Hydraulic disc brakes with 180mm rotors provide progressive, easy-to-modulate braking, helping you control how quickly the bike slows down.
That means more predictable braking when riding through traffic, carrying extra weight or facing less-than-perfect conditions.
Ready for More Than the Commute
A good everyday e-bike should make the rest of your journey easier too. The BK-U2 combines a rear rack, integrated lighting, Shimano 7-speed gears, TFT colour display with NFC start and an adjustable pneumatic seatpost.
From commuting and shopping to evening rides and weekend trips, the useful equipment is already built around the way you ride.

FAQ
Will I really get 150km of range?
The quoted figure is a maximum achieved under favourable conditions. Rider weight, assistance level, hills, temperature, tyre pressure and stop-start riding can all reduce real-world range.
How does it cope with rough roads?
The 29in tyres and 100mm suspension fork help reduce the harshness of broken tarmac and uneven cycle routes. It is designed as a city/trekking bike rather than a technical mountain bike.
Who is it suitable for?
The recommended rider-height range is 160–195cm, although fit also depends on leg length, riding position and personal preference.
