What parts do you need to build a fixed gear bike?

The frame and fork are the essential components of a fixed gear bike. The frame consists of the main tubes and is where the components are mounted. The fork is the part of the bike that holds the front wheel.

Headset

The headset is the set of bearings that allow the fork to rotate smoothly in the frame.

Stem

The stem is the part of the bike that connects the handlebars to the fork.

Handlebars

The handlebars allow the rider to control the bike.

Seatpost

The seatpost is the tube that allows the rider to raise and lower the saddle.

Saddle

The saddle is the part of the bike that the rider sits on.

Cranks

The cranks are the arms that connect the pedals to the bottom bracket.

Bottom Bracket

The bottom bracket is the set of bearings that allow the cranks to rotate smoothly in the frame.

Pedals

The pedals are the part of the bike that the rider pushes on to propel the bike forward.

Fixed Gear Hub

The fixed gear hub is the part of the bike that connects the rear wheel to the frame. It is called a "fixed gear" hub because it does not have a freehub, which means the rear wheel cannot rotate independently of the cranks.

Rear Wheel

The rear wheel is the wheel that is driven by the cranks.

Front Wheel

The front wheel is the wheel that helps the bike roll forward.

Tire and Rim

The Tire is the part of the bike that contacts the ground and is inflated with air. The tire and rim are separate parts that are combined to create the complete wheel.

Brake Lever and Caliper

The brake lever is the component, and the caliper is another component that allows the rider to stop the bike. The Brake lever is usually mounted on the handlebars, while the caliper is mounted on the frame or fork.

Brake Pad

The brake pads are the part of the brake that comes in contact with the rim of the wheel to slow down or stop the bike.

Chain

The chain is the component that connects the front and rear sprockets. It is driven by the pedals and drives the rear wheel.
