Learn more about the structures of a bike using these hands-on bike parts diagrams that we have collected for you! In these 101 Diagramss, the detailed structures of bike are illustrated clear pictures. Follow these diagrams to study more about bicycle parts! We’ll start by giving you the simple part diagram below.
As you can see in the bike parts diagram above, the main parts of a bike are wheels, frame, seat, handle bars, and components. Cranks arms are turned by placing force on the pedals and they then rotate the front chainrings. The bottom bracket is an axle with bearings which connects the crank arms and allows them to turn freely. Some riders choose to upgrade from the old cartridge style bracket to a new external bottom bracket which tends to be a bit lighter and stiffer. Scroll down to the bottom of this page to see the diagrams of most major bike parts.
Derailleurs are the mechanical system that helps you to change gear on the bike. The rear cassette determines the range of gears that you have on the bike. Made up of several sprockets of varying sizes, each cog will require a different level of pedal power with the larger sprockets providing easier gears and the smaller sprockets providing harder gears. Sprockets are the metal discs with ‘teeth’ on them on which the chain is hooked.
All these pictures are printable and you are also provided the worksheets or unlabeled versions of the diagrams. Learn more about the other structure diagrams by browsing through our latest posts or looking it up on the search column!
