BK5S – Compact and Practical Folding Electric Bike for Everyday Use
The BK5S by Koolux is a smart, lightweight, and foldable electric bike designed for those who value convenience and mobility. Thanks to its folding frame, this model is easy to store and transport – it fits comfortably in a car trunk or even a small apartment. When unfolded, the bike measures 139 x 53 x 104 cm, and folded, it takes up only 86 x 37 x 66 cm.
Weighing just 23.8 kg, the BK5S can carry riders up to 120 kg, making it suitable for various body types. The 350W rear hub motor delivers smooth pedal assistance and allows speeds of up to 25 km/h (or up to 32 km/h with the speed limiter removed). With pedal assist, you can travel up to 70 km on a single charge.
Equipped with a 36V 10.4Ah lithium-ion battery, it charges fully in 5 to 6 hours. Front and rear disc brakes provide reliable stopping power, and the 16-inch wheels offer great maneuverability and comfort, especially in urban environments.
The BK5S is an excellent choice for anyone seeking a compact, stylish, and reliable electric bike at an affordable price. Perfect for commuting, daily errands, or relaxed weekend rides around town.
