KOOLUX BK6S 3.0 Folding Electric Bike

Bike is designed for riders who want maximum convenience, strong performance, and modern e-bike technology in a compact folding frame. Built for both city commuting and leisure riding, this model offers a powerful combination of durability, comfort, and efficiency. At its core lies a dependable 36V 13Ah 468Wh battery, giving riders enough power to handle daily travel needs without worry. The battery uses 18650 Lithium-Ion cells, which are widely known for their high energy density, long lifecycle, and dependable stability. Whether you’re commuting to work, running errands, or enjoying weekend rides, this advanced battery system ensures consistent performance throughout each journey.

The BK6S 3.0 features a removable battery, allowing you the flexibility to charge it on or off the bike. The included 42V 2.0A charger restores full power in approximately 5–6 hours, making it easy to recharge overnight or during the day while you work. Once fully charged, the bike provides a range of 45–90 km, depending on rider weight, terrain, and pedal-assist level. This range is ideal for urban commuters who need reliable daily transportation, as well as recreational riders who value long, uninterrupted trips.

With a standard speed of 25 km/h, the BK6S 3.0 adheres to e-bike regulations in most regions while delivering a smooth and controlled ride. The bike is well-balanced at 25.8 kg net weight and 30 kg gross weight, offering sturdiness without being excessively heavy. This balance is especially helpful for a folding electric bike, as it ensures both portability and structural integrity. The robust aluminum alloy frame enhances durability and corrosion resistance, ensuring the bike remains strong even after years of regular use.

A standout feature of this model is its set of 20 × 3.0-inch tires, which provide excellent traction, improved shock absorption, and increased stability. These wider tires help riders navigate city streets, gravel paths, or slightly uneven surfaces with confidence. Paired with a front fork suspension system, the bike significantly reduces the impact of bumps and road imperfections, creating a smoother, more comfortable riding experience.

For stopping power, the KOOLUX BK6S 3.0 relies on reliable mechanical brakes, offering consistent braking performance and easier long-term maintenance. Combined with the bike’s strong frame and wide tires, the braking system ensures safety and stability even at higher loads. The bike supports a max load of 120 kg (264 lbs), accommodating a wide range of riders and allowing for additional cargo when needed. Its climbing capability of up to 25° makes it suitable for hilly cities or elevated paths.

Riders also benefit from the intuitive LCD display, which provides essential information such as speed, battery level, distance, and pedal-assist mode. This makes it easy to monitor your ride and adjust performance settings as needed. The bike also features an IP54 waterproof rating, providing protection against splashes, dust, and light rain. This ensures dependable year-round performance, even in varying weather conditions.
