Subjects are covered in a four-week rotation beginning the first week of every month. Note that there’s no need to do the classes in order, or go to the beginner’s class before any others. Classes are free and open to all levels of experience and expertise. As always, people can use the tools to repair their own bikes, though they cannot expect guidance from the mechanics. People who want to work on their own bikes and need the help of a mechanic should come to the Open Workshop every Thursday (Manhattan), Wednesday and Sunday (Brooklyn).

First Week–Basics for Beginners: Identifying parts and tools, diagnosing common problems and things you should know before buying a bike. We will also cover how to change tires and fix flats.

Second Week–Cables and Housing: Installing, adjusting and tightening derailleur and brake cables. Learn how to fix skipping gears and rubbing brake pads.

Third Week–Cups, Cones and Bearings: Overhauling and rebuilding cup and cone bottom brackets, hubs, and headsets. Identifying when problems are present and whether they need a simple adjustment or a more involved overhaul.

Fourth Week–Wheels and Spokes: How to true a wheel and replace broken spokes.

Fifth Week (if applicable)–Open Workshop
