My cousin just moved to DC for the summer from CA and she's looking for a cheap commuter bike she can use to get around the city. Anyone selling one of know of anyone who is? Shoot me an email dctri26.2 (at) gmail.com Thanks!
You know, I was looking for one too a couple months ago. I got a couple responses from members, but all the wrong size bike. So I shopped at all the local shops. One stood out: Arrow Bicycle right out Rhode Island Ave across the border from DC (5108 Baltimore Avenue Hyattsville, MD 20781)
I got a new Giant Escape for under $400. It's awesome and I ride it everyday now. All the other similar bikes I found were in the $600 and up range.
Chris and Chris who own the shop are old time DC Tri friends.
Consider getting a solid bike lock, too. Commuter bikes are two-wheeled gold in this town.
