This Model Is Fully Compliant With UK Road Regulations
This bike is built to comply with UK Electrically Assisted Pedal Cycle (EAPC) regulations, meaning it can be used on public roads and cycle paths without registration, tax, or a licence. Motor assistance is limited to 250W and cuts off at 15.5 mph (25 km/h).
See UK LegislationYour All-Terrain Commuter, Ready to Fold
The Koolux BK10S is built for UK riders who want one e-bike that handles the daily commute, weekend trails, and everything in between. Its 250W motor and 56-mile range give you the confidence to leave the car at home, while the folding aluminium frame slips into a car boot or train luggage rack without fuss. Whether you're weaving through city traffic or exploring a canal towpath, this bike delivers dependable power and a ride that feels stable and controlled.
Power That Meets UK Road Law
The Koolux BK10S is powered by a 250W motor, the maximum allowed under UK regulations for use on public roads without a licence or registration. It assists you smoothly up to 15.5 mph, then lets you pedal under your own steam. That means you get a helpful boost on hills and headwinds while staying fully compliant with UK e-bike law.
Ride Up to 56 Miles on a Charge
The 48V 13Ah lithium battery gives you a real-world range of up to 56 miles, so a full day of errands or a long leisure ride is well within reach. When it's time to top up, the 2A charger takes 7-8 hours to bring the battery back to full. The battery is hidden inside the frame for a clean look and added protection from the elements.
Comfort and Control on Any Surface
Front fork suspension and 20 x 4.0-inch fat tyres soak up bumps from potholes, gravel, and uneven cycle paths, keeping your ride smooth and your hands relaxed. The Shimano 7-speed gear system lets you find the right cadence whether you're climbing a steep hill or cruising on the flat. With a maximum load of 265 lbs, the BK10S carries you and your shopping with ease.
Mechanical Brakes for Reliable Stopping
The Koolux BK10S uses mechanical disc brakes, which offer consistent stopping power in wet or dry conditions—a real advantage on rainy UK commutes. The brake levers are easy to reach and modulate, giving you confidence when traffic slows suddenly. Combined with the bright front headlight and integrated rear safety light, you're visible and in control from dawn to dusk.
Clear Display, Simple Controls
A multifunctional LCD display keeps essential ride data in view: current speed, battery level, and distance travelled. The handlebar-mounted controls let you switch assist levels without taking your eyes off the road. Everything is laid out for intuitive use, so you can focus on the ride, not the settings.
Built to Fold, Ready to Go
The aluminium alloy frame folds down in seconds, making the BK10S easy to store in a flat, under a desk, or in the boot of a car. At 65 lbs, it's substantial enough to feel stable at speed but still manageable for lifting into a train carriage. Full fenders keep spray off your clothes, and the rear rack is ready for panniers or a basket—practical touches for everyday UK riding.
