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.

KOOLUX X3 electric off-road bike with 500W motor, 45 km/h speed, 85 km range, 648Wh battery, 26 inch wheels

Effortless urban travel meets off-road adventure

Enjoy a ride that blends modern style with eco-friendly practicality, perfect for your daily commute or weekend escapes. The KOOLUX X3 pairs a punchy electric motor with quick acceleration and nimble handling, so gliding through city streets or tackling rougher paths feels effortless. A high-capacity lithium-ion battery gives you an impressive range on a single charge, letting you explore without constantly watching the gauge.

Comfort is built in with an ergonomic handlebar, a cushioned seat, and adjustable parts to suit riders of different sizes. The lightweight frame and foldable design make storage and transport simple, slotting easily into your everyday routine. Safety comes first with integrated LED lights that boost visibility in low light, while the responsive braking system delivers precise control and dependable stopping power when you need it most. An intuitive display keeps speed, battery life, and other key info right at your fingertips, so you can focus on the road ahead.

Charge anywhere with the removable 48V battery

Take the battery out and top it up wherever suits you, whether at home, the office, or a café. The 48V 13.5Ah pack is neatly tucked into the frame for a clean look, yet easily removable for hassle-free charging. Depending on how and where you ride, you can expect between 28 and 53 miles of range on a full charge, giving you plenty of freedom for daily trips.

Strong hill-climbing torque from a 250W motor

Feel confident on inclines and busy junctions with up to 58Nm of torque that pushes you forward smoothly. The 250W motor delivers brisk acceleration and steady power, making light work of slopes and varied road surfaces. It’s tuned to meet UK regulations, so you can ride legally on roads and cycle paths while enjoying responsive performance.

Smooth out bumps with front suspension

Glide over potholes, cobbles, and uneven tarmac with a front suspension system that soaks up shocks effectively. Whether you’re weaving through city traffic or venturing onto bumpy country lanes, the suspension keeps the ride stable and controlled. You’ll arrive fresher and more comfortable, even after longer journeys on less-than-perfect British roads.

Built to handle real British roads

You'll feel the difference with a sturdy aluminium frame and front suspension fork that smooth out potholes and uneven tarmac on your daily commute. The 26-inch Kenda pneumatic tyres give you confident grip whether you're cutting through city streets or tackling a gravel bridleway at the weekend.

Shimano 7-speed gearing lets you find the right cadence for every incline, while the 58 Nm hub motor delivers strong, steady assistance up to the UK legal limit of 15.5 mph. With a peak output of 500 W, it's got the torque to carry you and up to 120 kg of rider plus cargo without breaking a sweat.

Go further on a single charge

The 48 V 13.5 Ah lithium-ion battery gives you up to 85 miles of range in ideal conditions, so you can ride from Croydon to Brighton and still have power to spare. Even with the throttle unlocked on private land, you'll cover around 28 miles at higher speeds—plenty for most off-road adventures.

A full charge takes 6 to 7 hours, and the multifunction LCD display keeps you informed of speed, battery level, and assist mode at a glance. Everything you need comes in the box, including charger, pump, lock, and tools, so you can get set up and out riding with minimal fuss.
