Koolux BK6S 750W folding electric fatbike: power, stability and practical format

The Koolux BK6S 750W is a folding electric fatbike designed for users looking for a powerful, stable and easy-to-store bike. With its 750W motor, 48V 13Ah battery and wide 20x4.0 tyres, it offers a dynamic and comfortable ride for outings, trails and varied surfaces.

Its folding format makes it easier to store, transport or put away than a classic fatbike. It is an interesting model for those who want to enjoy the fatbike style, good traction and real riding comfort, without having a bike that is too bulky for everyday use.

🚴‍♂️ Why choose the Koolux BK6S 750W folding electric fatbike?

Robust look & folding format:

The BK6S has a true fatbike identity with its wide 20x4.0 tyres, imposing frame and all-terrain style. Its folding system adds a very practical advantage: it becomes easier to store in a garage, storage room, suitable vehicle or reduced space.

750W motor for dynamic riding:

Equipped with a 750W electric motor, the Koolux BK6S delivers sharp acceleration and powerful assistance. It efficiently supports starts, climbs and trail sections, with a more responsive riding feel than a classic electric bike.

48V 13Ah battery and up to 45 km range:

Its 48V 13Ah lithium-ion battery allows you to ride up to 45 km depending on usage conditions. Actual range depends on the rider’s weight, assistance level, terrain, outside temperature and type of surface.

Wide 20x4.0 tyres for greater stability:

The 20x4.0 tyres provide excellent stability and better grip on uneven surfaces. Their volume also improves comfort by absorbing part of the vibrations, making rides more pleasant than with classic thin tyres.

Front and rear disc brakes:

The Koolux BK6S is equipped with front and rear disc brakes. This configuration provides progressive braking suited to leisure riding, even with a heavier and more powerful bike than a standard electric model.

A folding fatbike ready for leisure rides:

With its folding frame, 120 kg maximum load, IP54 protection and up to 45 km range, the BK6S is a versatile, practical and pleasant model to use. It is aimed at riders who want a compact electric fatbike once folded, but solid and comfortable once on the saddle.
