Koolux X3 Electric Bike – 48V Long Range Commuter Ebike

The Koolux X3 Electric Bike is a powerful and practical commuter eBike designed for everyday urban riding, offering a strong balance of performance, comfort, and value.

Built around a lightweight aluminium frame with full-size 26” wheels, the X3 delivers a stable and familiar riding experience, making it ideal for commuting, leisure rides, and longer journeys.

At its core is a 250W rear hub motor (UK road legal) with up to 500W peak output and approx. 58Nm torque, providing smooth acceleration and reliable assistance for hills and daily riding.

Powering the bike is a 48V 13.5Ah removable lithium-ion battery, offering a real-world range of approximately 45–85km depending on riding conditions and assist level.

With Shimano 7-speed gearing, front suspension, disc brakes, and commuter-ready components, the Koolux X3 is built to deliver a comfortable, controlled, and dependable ride.
