We get many questions about the most essential tools for bike maintenance, especially for fixed gear bikes. You can save a good amount of money if you can fix your bike yourself.

Below list of tools is approved and recommended by the Bike Ethics team:

Please note that I do not true my wheels. I do not have expensive trueing equipment, and I prefer to let the local bike shop handle that part for me. I doubt that I could do as good a job as the professionals can.
