Pro, did you see Folding Bike on Today Show?
I think you said you may use your current bike until it is completely worn out before getting a new one.
This morning on Today, they showed various types of alternate transport. One of them was a Folding Bike. Overall, I don't know how comfortable it would be compared to a regular bike, but it was interesting to me to find out they make those.
In Google Images, I typed in Folding Bike, and it brought up pictures of a lot of different ones. Maybe by the time you are ready to Buy Again, they will have a model that you would like :)
MSNBC.com/Today show has the clip loaded from this morning if you want to see it. Talk to you later! :)
