Responsive Mid-Drive Support
The Bafang M430 mid-drive delivers up to 120Nm of torque where it matters most: starts, climbs and loaded rides. Combined with a torque sensor, assistance responds to your pedalling effort for a more natural feel and better control across changing terrain.
Range for More Than the Commute
A removable 48V 15Ah battery with LG 21700 cells provides up to 175km of assisted range under suitable conditions. It gives you more flexibility for longer commutes, countryside routes and weekend touring without planning every ride around the next charge.
Comfort Beyond Smooth City Streets
A 100mm lockout air fork and 27.5-inch Kenda trekking tyres help absorb broken tarmac, gravel paths and uneven roads. Adjust the suspension to the route and enjoy a more settled ride when your journey extends beyond well-maintained cycle lanes.
Controlled Braking When Conditions Change
Tektro hydraulic disc brakes with 180mm rotors provide progressive, predictable braking with less hand effort. Combined with reflective tyre strips and integrated K-mark lighting, BK-S3 is designed with visibility and everyday control in mind.
Built Around Real Everyday Use
Fast 1.5–2 hour charging reduces downtime, while the removable battery makes indoor charging easier. A rear rack, Shimano 7-speed drivetrain, adjustable seatpost and central TFT display complete a trekking setup built for commuting, errands and longer weekend rides.
From City Streets to Open Roads.
Comfortable enough for everyday commuting, capable enough for longer weekend routes. The BK-S3 brings natural mid-drive assistance and trekking versatility to every ride.
Made for the Road Beyond Routine.
A refined trekking setup combining natural pedal response, long-distance capability and everyday practicality for wherever your week takes you.
Comfortable for the commute, capable enough for longer routes and equipped for the journeys that don't end at the city limits.
Up to 175km. Back Faster.
The 720Wh removable battery provides up to 175km of assisted range under suitable conditions. When it is time to recharge, the 7.5A charger cuts waiting time to approximately 1.5–2 hours—ideal when the bike is used frequently.
Power That Feels Natural
The Bafang M430 mid-drive produces up to 120Nm of torque, while the torque sensor continuously responds to your pedalling effort. The result is assistance that feels progressive rather than abrupt—particularly useful when starting, climbing or carrying extra weight.
Tuned for Uneven Roads
A 100mm air suspension fork can be adjusted to suit rider weight and riding conditions, helping reduce vibration and impact on broken asphalt, gravel and uneven routes. Lockout keeps the front end firmer when suspension movement is not needed.
Braking You Can Modulate
Tektro hydraulic brakes and 180mm rotors provide smooth, progressive braking with less hand effort. That added control becomes especially valuable when carrying luggage, descending or riding on changing road surfaces.
Trekking Means Practical
Longer rides require more than motor performance. A rear rack, puncture-resistant Kenda tyres, integrated lighting, adjustable seatpost and Shimano drivetrain make the BK-S3 practical enough for commuting while remaining ready for weekend touring.
Features and Details
Central TFT Display
The centrally positioned TFT display keeps key riding information easy to read at a glance, helping you check assistance level, speed and ride status without taking focus away from the road.
Air-Adjustable Seatpost
Fine-tune saddle height and riding position more easily for different riders, routes and comfort preferences. A practical upgrade for frequent commuting and longer trekking rides.
Integrated Front Light
The built-in front light keeps the bike visually clean while providing dependable illumination for early starts, evening commutes and low-light riding without needing a separate lamp.
Rear Rack Ready for Daily Use
Carry commuting bags, shopping or light touring gear without relying on a backpack. The rear rack adds useful carrying capacity without turning the BK-S3 into a bulky cargo bike.
Shimano 7-Speed Drivetrain
7 mechanical gears give you useful control over cadence when starting, climbing or riding faster on flatter roads, working alongside the motor rather than leaving everything to electric assistance.
Adjustable Handlebar
The BK-S3's handlebars are adjustable up and down by 30°. You can adjust the handlebar angle based on your height and riding posture, allowing the BK-S3 to perfectly adapt to your riding style.
Rear Light
A neatly integrated rear light improves visibility from behind and keeps everyday lighting ready whenever the bike is in use, with no extra accessory setup required.
