The design of LiXa's power assisted Electric Bicycle is different from our other MC01 and MC02 models. Given the cool design concept and application scenarios of LiXa, we have installed its Lithium Battery design above the lower tube of the Bike Frame, making mountain cycling more casual and free spirited. Compared to MC01 and MC02, installation and disassembly are easier and more convenient. The battery box for installing Lithium Batteries follows the shape of the Bike Frame and blends seamlessly with the entire Bike Frame. After installation, it is impossible to see from the outside that this Lithium Battery has been installed separately. The entire power assisted driving system adds a lot of beauty from another side. The weight of Lithium Batteries is also just right, not very heavy, and will not affect your riding experience and comfort. The weight is not very light, and you don't have to worry about slipping or feeling heavy on your head and feet while riding. Because our Lithium Batteries have been treated with waterproofing, cyclists don't have to worry about getting wet on rainy days. Our designers have put a lot of efforts into considering every detail for our mountain and wilderness cycling enthusiasts.
