# KOOLUX BK6S Foldable Electric Bike 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 BK6S Foldable Electric Bike** **Specifications Breakdown** **Model:** KOOLUX BK6S **Bike Type:** Foldable fat-tire electric bike **Colour:** Black, Grey, Blue **Versions:** 500W version, 750W version **Battery:** 48V 13Ah lithium-ion battery **Battery Capacity:** 624Wh **Wheel Size:** 20-inch wheels **Tyres:** 20 × 4.0-inch fat tyres **Brakes:** Front and rear disc brakes **Climbing Ability:** Up to 25° **Water Resistance:** IP54 **Maximum Load:** 120 kg (264 lbs) **Bike Weight:** 33.2 kg (73.2 lbs) **Package Weight:** 40 kg (88.2 lbs) **Product Dimensions:** 182 × 60 × 110 cm (71.7 × 23.6 × 43.3 in) **Package Dimensions:** 93 × 55 × 76 cm (36.6 × 21.7 × 29.9 in)  **500W Version** **Motor Power:** 500W peak **Top Speed:** Up to 25 km/h (15.5 mph) standard / up to 32 km/h (19.9 mph) on some store listings **Range:** Up to 45–90 km (28–56 miles)  **750W Version** **Motor Power:** 750W motor **Top Speed:** Up to 50 km/h (31 mph) **Range:** Up to 45–90 km (28–56 miles)  **What’s in the Box** 1 × KOOLUX BK6S Electric Bike 1 × Battery 1 × Charger 1 × Tool kit 1 × User manual  **FAQs** **What is the difference between the 500W and 750W KOOLUX BK6S?** The main difference is motor output and speed.
