KOOLUX X2 Step-Thru Electric Bike

KOOLUX X2 Step-Thru Electric Bike – Comfort, Power & Everyday Freedom

The KOOLUX X2 Step-Thru Electric Bike is designed to bring comfort, power, and convenience together in one beautifully engineered package. Built for commuters, leisure riders, and anyone who wants a reliable, efficient, and enjoyable cycling experience, the X2 combines modern technology with a rider-friendly step-thru frame that makes mounting and dismounting effortless. Whether you’re navigating busy city streets, climbing hilly terrain, or simply cruising on weekend rides, the KOOLUX X2 delivers smooth performance every time.

At the core of the X2 is a robust 500W motor that gives you the strength needed to handle diverse riding conditions. This motor provides strong torque for quick acceleration and the ability to climb inclines of up to 25°, offering outstanding versatility for both urban and semi-off-road routes. The smooth and responsive motor assistance makes every ride feel light and controlled, reducing effort while increasing enjoyment.

Powering this motor is a premium 48V 15Ah (720Wh) 21700 lithium-ion battery. The use of 21700 cells—known for their high energy density and long lifecycle—ensures better efficiency and longer ride times compared to traditional batteries. Riders can expect a practical range of 65–80 km on a full charge, depending on terrain, riding mode, and load. This makes the KOOLUX X2 ideal for full-day rides, work commutes, or running errands without frequent recharging. When charging is needed, the included 54.6V 2.0A charger replenishes the battery in approximately 6.5–7.5 hours, making overnight charging simple and convenient.

The bike is built around a lightweight yet strong aluminum alloy frame, offering a perfect balance of durability and easy handling. Weighing 35 kg, the KOOLUX X2 provides a stable and confident feel on the road. The high load capacity of 120 kg allows the bike to accommodate a wide range of riders, plus additional cargo or accessories such as a rear rack, basket, or panniers. This makes it a practical option for both daily commuting and recreational journeys.

Comfort has been thoughtfully integrated into every part of the design. The front fork suspension absorbs bumps, vibrations, and uneven road conditions, providing a smooth and enjoyable ride even on rougher surfaces. Paired with 26×1.95 inch Kenda tires, known for durability and strong grip, the bike handles city streets, light gravel, and wet surfaces with confidence. These tires provide excellent traction, stability, and comfort, making the X2 suitable for all-weather and multi-surface riding.

Safety is enhanced with powerful hydraulic disc brakes, which offer superior stopping power regardless of speed or weather conditions. Hydraulic braking systems are more responsive and consistent than mechanical brakes, ensuring quick and controlled stops on descents, in traffic, or during emergency situations. This gives riders added peace of mind during every journey.

To adapt to different riding conditions and personal preferences, the KOOLUX X2 is equipped with a reliable Shimano 7-speed gearing system. Riders can shift smoothly between gears whether climbing steep roads or cruising on flat terrain. This gearing flexibility enhances performance, efficiency, and comfort on every type of ride.

The bike maintains a standard speed of 25 km/h, making it compliant with road regulations across many countries. The IP54 waterproof rating protects the bike against dust and splashes, allowing you to ride confidently through rain or puddles without worry.
