The Koolux BK6S PRO is the folding e-bike for riders who refuse to choose between range and portability. With a dual-battery system delivering up to 93 miles per charge, it’s built for long commutes, weekend adventures, and everything in between. Whether you’re navigating city streets or exploring rough trails, this bike offers the power and stability to keep you moving.

Powerful 250W Motor for Steady Assistance
Enjoy smooth, reliable acceleration from a 250W motor that complies with UK road law. Paired with Shimano 7-speed gearing, it gives you the right amount of assistance for hills and headwinds, while keeping you at a legal assisted speed of 15.5 mph. The result is a ride that feels natural and controlled, whether you’re commuting or exploring.

Dual Batteries for Up to 93 Miles
The BK6S PRO features two removable lithium-ion batteries—a 13Ah frame battery and a 10.4Ah rack battery—for a combined 23.4Ah capacity. That means up to 93 miles of assisted riding on a single charge, so you can leave range anxiety behind. Both batteries charge in around 6 hours, and because they’re removable, you can top up indoors with ease.

Fat Tires and Suspension for a Comfortable Ride
20×4.0 inch Kenda fat tires and a front fork suspension work together to smooth out bumps and rough surfaces. The wide tires improve grip and stability on everything from wet city streets to gravel paths, while the suspension absorbs shocks for a more comfortable ride. You’ll feel confident and in control, no matter the terrain.

Mechanical Brakes for Dependable Stopping Power
Mechanical brakes provide consistent, reliable stopping power in all weather conditions. They’re easy to maintain and adjust, giving you peace of mind on every ride. With a maximum load of 265 lbs, the bike remains stable and responsive even when carrying cargo.

Smart LCD Display and Integrated Lighting
Stay informed with a weatherproof LCD display that shows key ride data at a glance. The StVZO-certified front headlight and integrated rear safety light keep you visible and safe on UK roads after dark. The display is easy to read in daylight and rain, so you can focus on the road ahead.

Folding Iron Frame with Practical Extras
The BK6S PRO folds down for easy storage in flats, offices, or car boots, thanks to its sturdy iron frame. A rear rack and full fenders add everyday practicality, keeping you and your belongings clean and dry. At 87 lbs, it’s a solid build that feels stable on the road, yet it folds compactly when you need to carry it indoors.
