The KOOLUX BK5S
Take on the city with the KOOLUX BK5S Electric Bike — a compact, foldable ride built for convenience and performance. With up to 70 km of range, a road-legal 25 km/h speed, and a sturdy steel frame that folds in seconds, it’s the perfect balance of portability and power for daily commutes or weekend rides.
KOOLUX
KOOLUX began when three young cycling enthusiasts took on a challenging 38-mile mountainous ride and found themselves walking their bikes up steep terrain in the dark, cold and exhausted. Determined to solve that struggle, they set out to design electric bikes to help riders keep going. After winning recognition in a campus tech competition, they formally founded the company under the name “KOOLUX” five years later. Today, the brand is known for bringing stylish, powerful, and accessible e-mobility solutions to riders around the world.
