KOOLUX KL6S Electric Folding Bike
You can choose between 3 driving modes: pedal assist mode, pure electric mode (if you use the throttle grip included as an accessory) and classic pedal mode. In normal pedal mode, you can experience unique acceleration with the 7-speed Shimano gears and mechanical gears. In moped mode and pure electric mode, you can enjoy an unexpectedly fast driving experience.
Efficient, powerful electric motor: The KOOLUX e-bike is equipped with a 250W 48V motor that can easily handle gradients of 25%. With the integrated removable 15.6AH battery, the range is about 70-120km with a charging time of 6-7 hours. If you love excitement and challenges, you could try this mountain bike for a non-stop adventure.
Intimate Design: The bike features an aluminum alloy frame, which has low density and high strength. The folding design is easy to carry and saves space. Don't underestimate the design of the openwork saddle, it is not only comfortable and breathable, but also prevents water accumulation. The bike also has an easy-to-read LCD display (shows battery, mileage, speed, assist level, error code, etc.) as well as headlights and reflectors to ensure your safety.
Improved circuit: You can choose from 3 riding modes (pedal assist mode, pure electric mode and normal pedal mode). In normal pedal mode, you can experience unique acceleration with the 7-speed Shimano gearbox and mechanical gears. In moped mode and pure electric mode, you can enjoy an unexpectedly fast riding experience.
Advanced security features: Safety is our top priority. Our electric bike is equipped with hydraulic braking systems, bright LED lights and a sturdy frame. It is ideal for beginners and experienced riders and ensures a safe ride in all conditions.
Comfortable shock absorption: Equipped with front suspension and large, high-capacity low-pressure tires that also act as shock absorbers, the bike offers more balance and control on rough mountain roads. The front and rear dual disc brakes and electronic brakes provide all-round protection for safe riding.
Professional 20" Fat Ebike: KOOLUX electric bikes specially use the extra strong professional Kenda 4.0 Fat tires, which are wear-resistant and puncture-proof. You can ride freely in both the mountains and the city and explore the nature. Or you can experience the feeling of flying without obstacles in places like snow, beach, etc.
