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.

Freedom to ride further, effortlessly

Discover the joy of long-distance riding with the KOOLUX X9 Pro, built around a robust 750 W motor that peaks at 1000 W for smooth, responsive power whenever you need it. Twin 48 V batteries—each 15.6 Ah, giving a combined 31.2 Ah—let you cover up to 93 miles on a single charge, so range anxiety becomes a thing of the past.

Whether you're threading through city streets, tackling off-road trails, or cruising country lanes, the 20×4.0-inch tyres and dual suspension soak up bumps for a planted, comfortable ride. Hydraulic disc brakes, a 7-speed Shimano drivetrain, and three riding modes—electric, pedal-assist, and manual—mean every journey feels effortless, no matter the distance or terrain.

Styled with classic motorcycle cues, the X9 Pro blends standout performance with a sleek, modern look. It’s your perfect partner for the daily commute, a weekend adventure, or simply enjoying the freedom of the open road.
