The parts of a bike that work together as a subsystem are: • The Wheel • Drivers & Gears • Frames & Materials • Brakes & Steering • Aerodynamics • Human Power
When the pedals on a bicycle move, they turn the gear. When the gear turns, it moves the chain. The moving chain makes the back wheel turn – and that pushes the bicycle forward. ... The handlebars, frame, and front-wheel all work together for steering.
