Shannon, your Trek bike is beautiful, and the perfect first bike on which to learn. Start by asking friends and relatives if they can teach you to bike. If you can't find anybody, see if there is an REI in your area and inquire there. If you still can't find anybody, go to the nearest State Park on a Saturday morning, because that is where cyclists congregate to go for a ride, either in groups or solo, find where the cyclists park, and start asking if anyone can teach you. If you came up to me, I would say oh how fun and do it.

Once you learn how to ride on that bike, and you learn how much fun the bike trails are, you will be totally addicted to cycling.
