Another thing you should brush up on is bike repair and maintenance. You could join a bicycle cooperative or a community bike shop — click here to find one near you. In the one in my city, people volunteer to work on discarded or donated bikes which are then sold cheaply, or given to people who can't afford one. There are master mechanics to train and guide you, and you get one hour of shop time to work on your own bike for every hour you volunteer. It's a great way to meet people and learn from each other, and gain confidence in really knowing your bike inside out.
