The KOOLUX BK6S
The Koolux BK6S Electric Bike is built for riders who want exceptional range, versatility, and everyday practicality in a foldable electric bike. Designed to handle commuting, weekend exploration, and longer journeys, the BK6S combines powerful battery capacity with durable all-terrain design.
One of the standout features of the BK6S is its dual-battery system, which provides an extended riding range of up to 150 km per charge under ideal conditions. This long-distance capability allows riders to travel further between charges, making the bike suitable for longer commutes, countryside rides, and extended leisure trips. The removable batteries can be conveniently charged at home or wherever a power outlet is available.
The bike is built around a strong aluminium alloy folding frame, allowing it to be quickly folded for storage or transport. This makes it practical for apartments, offices, car travel, or mixed-transport commuting while still maintaining the strength and stability needed for everyday riding.
For improved comfort and stability, the BK6S rides on wide fat tyres, which provide excellent grip and shock absorption on a variety of surfaces including paved roads, gravel paths, and uneven terrain. The larger tyre profile also helps smooth out rough surfaces, creating a more comfortable ride over longer distances.
A Shimano 7-speed drivetrain gives riders the flexibility to adjust gearing for different terrain and riding conditions, whether navigating city streets, climbing gentle hills, or cruising along scenic routes. Reliable disc brakes provide consistent stopping power, helping riders maintain control in different weather and road conditions.
Despite its robust design and long-range capability, the BK6S maintains the convenience of a foldable electric bike, making it easier to store and transport than traditional full-size models.
Combining dual-battery endurance, fat-tyre stability, and foldable convenience, the Koolux BK6S Electric Bike is designed to deliver a versatile riding experience for commuters, explorers, and everyday riders who want both performance and practicality in one dependable e-bike.
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.
