How can I build fixed gear bikes?

To build a fixed gear bike, you will need to start with a frame and then add components such as a fixed gear wheelset, crankset, chain, pedals, brakes, and handlebars. You will also need tools like wrenches, screwdrivers, and a chain tool. Assemble the parts carefully, making sure everything is securely attached and adjusted properly. It's important to have some knowledge of bike mechanics and possibly seek guidance from a professional if needed.
