The KOOLUX X7 is a robust and high-performance fat-tire electric bicycle designed for both urban commuting and off-road adventures. Powered by a 750W brushless rear hub motor that generates 60-70 Nm of strong torque, this e-bike delivers a top speed of 25 km/h and smooth, responsive acceleration. It is equipped with a high-capacity 48V 25Ah lithium-ion battery offering 1200Wh of energy, providing an excellent range of 70-120 km on a single charge depending on rider weight, terrain, pedalling effort, and assist level. The battery is neatly integrated into the durable aluminium alloy frame while remaining fully removable for easy charging, with a full charge taking approximately 5-6 hours.

Built on strong 20-inch wheels fitted with extra-wide 20x4" fat tires, the X7 offers superior stability, grip, and cushioning on sand, snow, mud, or rough pavement. It features a reliable 7-speed gear system for versatile riding, powerful hydraulic disc brakes for confident and safe stopping power in all conditions, and pedal-assist functionality that seamlessly combines human effort with electric power. Additional comfort features include an adjustable seat post for riders of different heights.
