Powerful and Stable Motor
The KOOLUX folding electric bike features a 250-watt motor with a maximum power of 500 watts, providing robust and stable performance for your daily riding. With 2 riding modes (pedal assist and classic pedaling), as well as a Shimano 7-speed gearbox, it offers the power to climb hills or reach top speeds. The maximum speed is about 25 km/h, which can meet your commuting and camping needs.
4.0-inch tires conquer any terrain
The most impressive feature of the KOOLUX BK10S electric mountain bike is the 20” X 4.0 wide anti-slip tires, which allow for effortless riding in the snow, mountains, beach, and city. Combined with the excellent shock absorption of the aluminum alloy front fork, vibrations caused by uneven roads are effectively dampened, greatly improving riding comfort.
48V 13Ah Battery for Worry-Free Travel
The removable 48V/13AH battery is safe and reliable. With a maximum range of 35-90km with continuous pedal assistance, depending on weight and road conditions, the KL-BK10S offers two charging methods: charge the folding electric bike directly or remove the battery to charge it.

The KOOLUX BK10S city electric bike folds easily and is ideal for storing in a motorhome, off-road vehicle, boat or living room. The intuitive Smart Gauge display shows speed, battery level, distance travelled and more, while headlights and taillights ensure nighttime illumination.
