Quick Summary
The KOOLUX BK6S 4.0 combines rugged fat‑tyre traction with a powerful 750W motor and a high‑capacity 48 V 13 Ah battery. Designed for both urban streets and off‑road paths, it delivers stable handling and dependable performance.
Smooth Power Delivery
The 750W hub motor offers responsive acceleration and smooth pedal‑assist across seven levels, letting you tackle hills and headwinds without strain. A thumb throttle provides instant power when you need a boost.
Comfort & Control
Wide 4.0″ tyres and front suspension absorb bumps and maintain grip on loose or uneven surfaces. Dual mechanical disc brakes ensure consistent, controlled stopping power in all weather.
Smart Battery System
A lockable, removable 48 V 15 Ah battery provides long-range capability and convenient off‑bike charging. Built‑in protection circuits guard against over‑charge, over‑discharge, and overheating for safe, reliable use.
Tech You Can Trust
The clear backlit LCD displays speed, battery level, distance travelled, and assist mode at a glance. Simple handlebar controls let you switch assist levels and monitor ride data easily.
Built for Everyday Use
With its durable frame, fat‑tyre stability, and straightforward folding rack mount design, the BK6S 4.0 is ready for daily commutes, weekend adventures, and everything in between—wherever you choose to ride.
