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 everyday folding companion
The Koolux KL6S is built for UK riders who need a dependable, space-saving e-bike for the daily commute or a weekend ride through the park. Its folding frame slips into a car boot or a hallway cupboard, while the 250W motor and 74-mile range keep you moving without range anxiety. If you want a practical, comfortable electric bike that fits around your life, the KL6S earns its place.
Power that respects UK road law
The KL6S uses a 250W motor that delivers smooth, steady assistance up to the UK legal limit of 15.5 mph. That means you can ride on UK roads and cycle paths without needing a licence, tax or MOT. It’s the right amount of push for getting up hills and across town without breaking the rules.
Go further on a single charge
A 48V 15.6Ah battery gives you up to 74 miles of assisted riding, so a full week of commuting can often be covered on one charge. The battery is removable, so you can charge it indoors at home or at your desk. A full top-up takes 7-8 hours, ready for the next morning’s ride.
Comfort that smooths the road
Front fork suspension and 20 x 4 inch Kenda fat tyres soak up potholes and rough patches on UK streets. The upright riding position and padded saddle keep you comfortable on longer journeys. Shimano 7-speed gearing lets you find the right effort for any gradient.
Stop with confidence in any weather
Hydraulic disc brakes give you strong, predictable stopping power, even in the rain. The IP54 waterproof rating means the bike shrugs off puddles and light showers. An integrated rear safety light and StVZO-certified front headlight help you see and be seen on dark UK evenings.
Clear controls and a sturdy frame
The KL6S has an easy-to-read display that shows your speed, battery level and assist mode at a glance. The aluminium alloy frame is light enough to carry up stairs, yet strong enough to support a 265 lb rider. The folding mechanism is simple to operate and locks securely when open.
Practical features for daily life
A rear rack and full mudguards make the KL6S genuinely useful for errands and wet-weather commutes. The bike weighs 79 lbs, so it’s manageable to lift into a car boot or store in a flat. In the box you’ll find the bike, charger, and the tools needed for basic assembly.
