How to Repair a Fixed Gear Bike
A fixed gear bicycle differs slightly from other bicycles in that they function without a freewheel. This is most evident in the fact that coasting is not possible on a fixed gear bike. With the wheels spinning, the pedals are as well. Because fixed gear bikes contain fewer parts than geared bikes, they require less maintenance. However, occasional repairs can still be required.
Items Needed:
- 15mm wrench
- Bicycle chain lubricant
- Rag or cloth
Instructions:
- Use your ears to help identify any problems with your bike's gear. This is often the easiest and best way to find out what is wrong with your fixed gear bike. If you hear an unusual noise, like a grinding noise or anything else excessive, it is usually an indicator of a problem within the gear system, whether it is the chain, fixed cog or chain ring.
- Loosen the rear axle nuts that are located on either side with a 15mm wrench. Doing this will allow the wheel to be moved back and forth and remove the wheel. You will need to do this in order to complete Step 3.
- Adjust the tension on the bike chain. It should not be overly tight. This will result in the telltale grinding noise. However, it should not be too loose, either. This will cause the chain to fall off.
- Lubricate the chain. This should help greatly lessen any grinding noise coming from the chain. Keeping the chain regularly lubricated will also help maintain the lifespan of the gear system by helping keep the chain, cog and chain ring clean.
- Use your hands to spin the wheel several times. Wipe off any extra lube with a rag.
