Dahon Folding Bike...
For the past week, I've been contemplating buying a bike, but I didn't because of space (my building charges for bike storage—$25/month). I found this bike that folds up to the size of a small carry-on. The seat and handle bar are adjustable to fit people with bigger and/or smaller frames. The design of this bike really impressed me. I really couldn't believe that folding bikes have been around since 1982 because they seem so innovative now (back then, space wasn't an issue because I lived in LA).
When I went to the bike shop, I wanted to approximately spend $100 on a used bike, but they laughed at me. They told me that the cost of bikes have gone up, since gas prices have gone up. Bikes are in demand. My friend told me that he sees a lot of people with folding bikes riding the LIRR. Anyway, I justified this purchase by subtracting the cost of storage for one year ($300) from the cost of the bike ($430), which came close to my budget.
On the first day, I took it out for a ride, and noticed fellow folding-bike riders on the path. One fellow-rider rang his bell, and rhetorically shouted "Look, another folding bike!"
