The KOOLUX BK10S
The Koolux BK10S Electric Bike is designed for riders who want a practical folding e-bike that combines comfort, range, and versatility. Built to handle everyday commuting as well as weekend exploration, the BK10S delivers dependable performance while remaining compact enough for convenient storage and transport.
Powered by a high-capacity lithium-ion battery, the BK10S offers an assisted riding range of up to 120 km per charge under ideal conditions. This extended range allows riders to travel further between charges, making the bike well suited for longer commutes, leisure rides, and full days of exploration. The removable battery design makes charging simple and convenient whether at home, work, or anywhere with access to a power outlet.
The bike features a strong aluminium alloy folding frame, allowing it to collapse quickly for easy storage or transport. This makes it an excellent option for apartment living, office storage, car travel, or mixed transport commuting while still maintaining the strength and stability required for everyday riding.
For improved comfort and control, the BK10S rides on 20″ fat tyres, which provide excellent grip and shock absorption across a wide variety of surfaces. Whether travelling on city streets, cycle paths, gravel tracks, or uneven terrain, the wider tyres help smooth out bumps and deliver a stable and comfortable riding experience.
A front suspension fork further enhances ride comfort by absorbing vibrations from rougher roads and trails. The Shimano 7-speed drivetrain allows riders to easily adjust gearing for different riding conditions, making it easier to maintain an efficient pedalling rhythm whether cruising through the city or tackling gentle hills.
For safety and reliability, the BK10S is equipped with front and rear disc brakes, providing dependable stopping power in a variety of weather and road conditions. Integrated LED lighting improves visibility when riding in low-light environments, helping riders stay safer during early morning or evening rides.
A handlebar-mounted display keeps essential ride information visible at a glance, including battery level, assistance mode, and trip data, helping riders stay informed throughout their journey.
Combining long-range battery performance, fat-tyre stability, and foldable convenience, the Koolux BK10S Electric Bike offers a versatile and dependable solution for riders who want an electric bike capable of handling both everyday commuting and longer recreational adventures.
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.
