A bicycle uses wheels and axles, levers and pulleys to function. Pedals act as levers, chains and sprockets work as pulleys, while wheels and axles ensure smooth movement. Together, they reduce effort and improve efficiency.

Class 6 Vocational Education Kaushal Bodh Textbook chapter 3 Project 3 Maker Skills question answer
A bicycle combines multiple simple machines for efficient movement. Pedals work as levers to transfer force, chains and sprockets function as pulleys to transmit power, and wheels and axles reduce friction for smooth riding. Brakes also use the lever principle to slow down the bicycle. These machines work together to transform the rider’s effort into motion, making cycling easier, faster, and more energy-efficient.
