A gravity racer is a type of vehicle that moves without an engine, relying entirely on gravity to gain speed. Typically, these vehicles are built low to the ground and designed to be steered by the rider, often on downhill slopes. Gravity racers are usually made from lightweight materials to reduce resistance and increase speed. They are commonly used in racing events, where competitors aim to navigate tracks as fast as possible without the aid of motors. These vehicles offer an exciting, eco-friendly way to enjoy fast-paced downhill racing.
