You will need some tools to help you assemble a fixie bike once it arrives. Some of the tools include screwdrivers, wire cutters, a repair stand, and a pedal wrench. First, you need to unpack all the bike parts and get them ready for the assembly process.
First, start by placing the brackets and headset and adjust them accordingly. You can skip this if your fixed gear bike has sealed cartridge bearings. Next, install the handlebars and screw them into the stem bolts. After removing the wheels, you can grease the hubs and see if they can freely spin.
You will also need to grease other bike parts, like crank bolts and the water bottle cage. This helps prevent any damage to your bike and makes it easy to remove other bike parts for servicing in the future. Attach the right bike pedal and bolt it clockwise while bolting the other bike pedal on the left pedal counter-clockwise.
If necessary, you can adjust the brakes on your fixed gear bike. It is also important to lubricate the chain before you adjust the derailleurs. With this done, you will have assembled most of your fixie bike. Do not forget to adjust your bike saddle to fit your height and comfortable angle better.
