More Range for Everyday Freedom

A removable 720Wh battery gives the BK-U3 the energy reserve needed for repeated daily rides and longer weekend routes. With a maximum range of up to 175km under suitable test conditions, the benefit is not simply riding farther—it is having to think about charging less often during normal use.

Pedal Support That Follows Your Effort

The torque sensor responds to actual pedalling force, helping the motor deliver support in a more natural and controlled way. Combined with 55Nm of torque, it makes city starts, gradual climbs and changing riding speeds feel smoother and easier to manage during everyday riding.

Comfort Across Changing Urban Surfaces

The BK-U3 uses a 100mm suspension fork, suspension seatpost and wide 2.8in tyres to improve comfort across uneven streets, cycle paths and suburban routes. The adjustable handlebar angle also allows riders to find a more relaxed position for longer daily journeys.

Predictable Braking for Daily Riding

Hydraulic disc brakes provide progressive control in city traffic, on downhill sections and during repeated stops. Combined with reflective tyre details and integrated lighting, the BK-U3 is equipped around the needs of everyday urban and suburban riding rather than outright speed.

Easy to Live With, Day After Day

A low step-through frame makes mounting and dismounting easier, while the rear rack, mudguards and removable battery support regular commuting and errands. With an adjustable fit designed for riders around 170–195cm, the BK-U3 is intended to work as an everyday bike rather than a specialist weekend machine.
