Compact design for everyday freedom

Rediscover the joy of getting around with the Koolux X9 Mini, a bike that fits seamlessly into your daily routine. Whether you're nipping to the shops, commuting to work, or enjoying a leisurely ride along a canal towpath, its compact frame and stable build make every trip feel effortless. The intuitive controls help you build confidence on two wheels, encouraging a more active lifestyle without any fuss.

This e-bike is a brilliant way to get the whole family outdoors. It's approachable enough for teenagers finding their independence, yet practical for adults who want a reliable runaround.

Key specs at a glance

Powered by a 250W rear-hub motor that complies with UK regulations, the X9 Mini delivers smooth assistance up to 15.5 mph. The removable 48V 13Ah lithium-ion battery (624Wh) charges in around 7 hours and offers up to 50 miles of range in pedal-assist mode—plenty for most daily trips. A Shimano 7-speed gearset, dual disc brakes, and full suspension keep you in control on potholed city streets or gravel paths.

Built to handle real-world loads, it supports riders up to 19 stone and tackles inclines of 25 degrees with ease. The 16x4.0-inch fat tyres soak up bumps and provide reassuring grip, while integrated front and rear lights help you stay seen on busy UK roads. At 34.5 kg, it's substantial yet manageable, and the smart app connectivity adds a modern touch to your ride.

Responsive power and confident stopping

Feel the instant, quiet push from the 250W motor as you pull away from traffic lights, with a top assisted speed of 15.5 mph that's perfectly legal on UK roads. The electronic gear system lets you click through three levels of assistance, making light work of steep hills—even those 25-degree climbs you'd normally avoid. It's like having a tailwind whenever you need it.

Stopping is just as important as going, which is why the X9 Mini uses mechanical disc brakes front and rear. They deliver consistent, short stopping distances whether you're caught in a sudden downpour on the M25 feeder roads or cruising in dry summer sunshine. That dependable braking power gives you the confidence to ride in all conditions.

Removable battery for flexible charging

No need to drag the whole bike indoors—simply pop out the 48V 13Ah battery and charge it at your desk, in the kitchen, or wherever suits you best. A full charge takes about 7 hours, so you can top up overnight and be ready for the morning commute. With up to 50 miles of range in pedal-assist mode, you'll cover a week's worth of short trips without worrying about running out of juice.

Even on pure electric power, you can expect over 28 miles of range, making it a practical choice for longer journeys across town. Whether you're riding from the suburbs into the city centre or exploring country lanes at the weekend, the X9 Mini gives you the freedom to go further without the range anxiety.

You’ll feel in complete control, with the bike tracking true even when the surface gets rough.

Shimano 7-speed gears for every incline

Tackle steep hills and uneven ground without breaking a sweat. The reliable Shimano 7-speed gear system lets you find the perfect ratio for climbing, descending, or maintaining a steady pace on mixed terrain. It’s a proven solution that makes light work of snowy lanes, gravel tracks, and challenging off-road routes.

Fat 16x4.0-inch tyres grip any surface

Go anywhere with confidence on these chunky, anti-slip tyres designed for true all-terrain versatility. From sandy beaches and snowy paths to mountain trails and urban tarmac, the generous footprint delivers exceptional traction and stability. You’ll feel the difference as the bike floats over soft ground and holds firm on loose gravel.

LED lights keep you seen at night

Ride safely after dark with a bright LED headlight that illuminates the road ahead and a rear light that makes you visible to traffic behind. The integrated horn gives you a clear way to alert other road users, adding an extra layer of awareness on busy UK streets. Together, these features help you stay conspicuous and ride with peace of mind.

Ergonomic saddle supports long-distance comfort

Settle into a saddle shaped to follow the natural curve of your lower back, reducing pressure and fatigue even on all-day rides. The design strikes a careful balance between plush cushioning and firm support, so you can cover more miles without discomfort. It’s a small detail that transforms your journey into a genuinely enjoyable experience, whether you’re commuting or exploring the countryside.
