Pocket bikes are small, miniature motorcycles designed for recreational use. Typically measuring around 40 inches in length, they are powered by small engines, usually ranging from 40cc to 110cc. These bikes are popular among enthusiasts for their compact size and ability to be ridden in smaller spaces, making them ideal for backyard or closed-course riding. While pocket bikes can be fun, they are not street-legal in many areas due to their size and speed capabilities. Riders should always wear appropriate safety gear, such as helmets and pads, and be aware of local laws regarding their use. Proper maintenance is essential to ensure safety and performance.
