If you’re after an electric bike that delivers outstanding endurance, muscular motor performance, and confident control across any terrain, the KOOLUX X8 is engineered to exceed your expectations. From daily commutes to long-distance adventures, this is your dependable powerhouse for every ride.

It combines a 48V dual battery setup (30Ah + 35Ah) for an exceptionally long range of 112–137 miles, a robust 750W motor peaking at 1000W, 20×4.0-inch Kenda fat tyres, and hydraulic disc brakes front and rear. Strong hill-climbing ability and a stable frame make it a true all-rounder on UK roads and beyond.

Key specifications at a glance

The X8 is built around a foldable 6061 aluminium alloy frame, keeping weight manageable while staying tough. Its motor delivers 750W nominal and up to 1000W peak, paired with a dual lithium-ion battery (48V 35Ah + 30Ah) for serious range.

You can reach speeds up to 31 mph, though UK regulations limit assisted speed to 15.5 mph on public roads. In electric-only mode expect 75–112 miles, and with pedal assist up to 137 miles. A twist throttle, Shimano 7-speed drivetrain, hydraulic brakes, front suspension fork, colour LCD display, and 20×4-inch pneumatic tyres complete the package. The bike weighs 119 lbs, supports up to 330 lbs, and fits riders from 5'5" to 6'3".

Potent 750W motor for smooth performance

With a high-torque 750W motor, the KOOLUX X8 delivers strong, consistent power whether you’re navigating city streets or tackling rough terrain. Acceleration from a standstill feels responsive, and maintaining speed over long rides is effortless.

The standard speed is 15.5 mph to comply with UK road law, but the motor can be unlocked to reach 28–31 mph on private land. Stable power output ensures you can enjoy extended journeys without the motor fading.

Massive dual battery for ultra-long range

The X8 stands out with its huge lithium-ion capacity, combining a 48V 30Ah and a 48V 35Ah battery for a total of 65Ah. This gives you an exceptional range of up to 112–137 miles on a single charge, depending on mode and conditions.

It’s ideal for long commutes, touring, and extended outdoor rides across the UK. Reliable lithium-ion performance and a 7–8 hour charge time mean you can ride further, worry less, and enjoy true long-range freedom.

Smart display keeps you informed

The intelligent system syncs effortlessly with the KOOLUX app via Bluetooth, so you can track your journeys and adjust settings from your phone. It’s the perfect blend of modern tech and practical cycling, designed for UK roads and everyday adventures.

Hydraulic brakes for confident stopping

Ride with peace of mind knowing that front and rear hydraulic disc brakes give you precise, powerful stopping control. They respond instantly, shortening your braking distance even when you’re moving at the maximum 15.5 mph allowed under UK regulations. From steep descents to sudden stops in traffic, you’ll feel secure in all conditions.
