I got on the bike this am and realized I had a flat tire. I tried changing it myself and it did not go well as there were time constraints and issues such as I have never changed a flat tire by myself. I wanted to do change it so I can do it next time, but I also had to get to work. So I took the car today with the bike and tire. I am going to talk to a guy here at work who rides a lot and fixes his own bikes. I am hoping he will work with me while I change the tire and makes sure I am doing it right.
