Don't worry, I gave Rambod a tire so he didn't have money in his tire. It's a great trick when you have a hole in your tire and need to get to where you're going to fix it! Acts as a good buffer between the outside world and the tube inside.
Anyway, back to my point about biking not having to cost a lot of money. If you can't afford a new bike, can't afford a real bike tech to take a look at your bike issues, there's a solution. Bikerowave 3.o is a great place to stop by if you're having any issues with your bike or need help building one. It's a cooperative "Do It Yourself" repair shop run by knowledgeable volunteers. You pay by the hour or on a yearly basis for use of the shop space, knowledge and it's tools. There is no excuse for anyone to say they can't afford to ride. It's also a great place to meet a sleuth of fellow urban riders alike. (Sidenote: San Francisco has their own version called the Bike Kitchen.)
The best part of Bikerowave? Personality is written all over the walls--more specifically, the restroom walls.
