This Bike Is Not Road Legal. Private Land Use Only.
This bike cannot be ridden on public roads, pavements, or cycle paths in the UK. Its motor output and assisted top speed exceed the legal limits set by the UK Electrically Assisted Pedal Cycle (EAPC) regulations, which cap electric bikes at 250W motor power and 15.5 mph (25 km/h). Because this bike exceeds both thresholds, it is classified as a motor vehicle and would require registration, insurance, and a valid licence to use on public roads. This bike is designed exclusively for use on private land such as farms, estates, and off-road tracks where road traffic law does not apply.
See UK LegislationYour daily commute, reimagined
The Koolux X11 folding e-bike is built for UK riders who want to skip traffic, dodge train strikes, and arrive fresh. With a 750W motor, 50-mile range, and 15.5 mph assisted speed, it’s a practical alternative to the car for workdays and weekend errands. The foldable frame slips into a hallway or boot, making it ideal for flats, narrow terraces, and mixed commutes.
Power to flatten every hill
The 750W motor delivers strong, steady acceleration, so you can pull away from lights and climb steep city streets without breaking a sweat. Paired with a Shimano 7-speed drivetrain, it gives you the right gear for every gradient, from gentle rises to sharp climbs. UK regulations cap assisted speed at 15.5 mph, and the X11 gets you there quickly and smoothly.
Go further on a single charge
The dual-battery setup (48V 13Ah + 10.4Ah) gives you a real-world range of up to 50 miles, so a full day of errands or a long leisure ride is well within reach. The batteries are removable, so you can charge them indoors while the bike stays locked outside. A full charge takes 6.5–7 hours with the included 54.6V 2.0A charger.
Ride comfort that lasts all day
The front suspension fork soaks up potholes and rough tarmac, while the 20 x 4.0-inch fat tyres add cushioning and grip on wet or uneven surfaces. The upright riding position and stable handling make it easy to stay comfortable on longer journeys, even when the roads are less than perfect.
Stop with confidence, day or night
Hydraulic disc brakes give you powerful, controlled stopping in all weather, so you can ride safely through rain and traffic. The StVZO-certified front headlight and integrated rear safety light keep you visible after dark, while the IP54 waterproof rating means the bike shrugs off splashes and light rain.
Stay informed at a glance
The smart LCD display shows your speed, battery level, and assist mode clearly, even in bright sunlight. It’s weatherproof and easy to read, so you can keep your eyes on the road while checking your ride data. The controls are simple and intuitive, letting you switch assist levels without fuss.
Built tough for UK streets
The iron frame is solid and durable, with a maximum load capacity of 265 lbs, so it can handle a rider plus shopping or a pannier. Full mudguards keep spray off your clothes, and the rear rack is ready for panniers or a basket. The folding mechanism is robust and easy to use, making storage simple in tight spaces.
