KOOLUX BK6S PRO – Electric Bike

Koolux BK6S Pro: The Long-Haul Dual-Battery Commuter

The Koolux BK6S Pro is the “High-End” evolution of the folding fat-bike, specifically engineered for riders who prioritize extreme range and cargo capability. Featuring a unique dual-battery system and a heavy-duty reinforced frame, it is built to handle the extra weight of gear or long-distance touring while providing the stability of an all-terrain machine.

Key Specifications

• Dual-Battery Endurance: The standout feature of the BK6S Pro is its dual-power setup, combining a 48V 13Ah primary battery with a secondary 10.4Ah pack (23.4Ah total). This massive energy reserve delivers an incredible range of up to 150 km (93 miles) on pedal-assist, making it a true “range-anxiety killer.”

• High-Torque Performance: Equipped with a high-capacity 750W brushless motor (available in EU-legal 250W configurations), this bike provides the low-end torque necessary to haul heavy loads and conquer 25° inclines. It offers a smooth top speed of 25 km/h, which can be unlocked to 45 km/h for private use.

• Enhanced Stopping Power: To ensure safety while managing the weight of two batteries and a rider, the Pro version is upgraded with front and rear hydraulic disc brakes. These provide precise modulation and superior stopping force, even when riding in wet conditions or at higher speeds.

• All-Terrain Foundation: Mounted on premium 20″ x 4.0″ Kenda fat tires, the BK6S Pro offers exceptional grip and puncture resistance. The combination of high-volume air tires and a front suspension fork allows you to transition seamlessly from smooth asphalt to gravel paths and sandy trails.

• Heavy-Duty Utility: The frame is crafted from a durable, high-tensile alloy designed to support up to 150 kg (330 lbs). Despite its robust build, the 3-step folding mechanism remains intuitive, allowing the bike to be stowed in a van or garage. It comes complete with a Shimano 7-speed system, a large LCD display, and an integrated rear rack.
