This bicycle light has a USB rechargeable interface. It comes with a built-in 300mAh rechargeable lithium battery, which can be used for up to 2-6 hours, and takes 4 hours to fully charge.
The headlight and taillight feature a one-touch switch with four different lighting modes depending on your preference. It includes full brightness, medium brightness, fast blinking, and slow blinking.
The silicone mounting straps are designed with two openings that fit tightly around many sizes of seat posts, handlebars, seat risers, backpacks, helmets, and elastic to keep the lights safe and secure. They can be easily loosened and fixed, and no tools are needed.
