Re: solid inner tube and the results of
I have solid tubes on my motorized bicycle as well, and it is nice being able to run over nails, glass, thorns, etc without worry, but there's a definite trade off in comfort. My motorized bicycle beats me up everytime I ride it because I feel EVERY bump. Spent the day at home yesterday due to back trouble caused when my back tire hopped into a deep rut and back out. Didn't feel it too badly until the next morning, when it was all I could do to sit up and dial the phone to tell my boss I wasn't coming in.
My Trek pedal bike has slime filled / thorn resistant tubes, resulting in a much more comfortable ride. My next motorized bicycle will have these tubes instead of the solid ones.
