I went to the local bike shop and picked up some tubes and treads and a few other things.
By the time I have gotten to the end of this blog posting I have finished cleaning the front rim and installing the new tube and tread. An up close look at the rim has shown flaking and rust. I am not sure if I want new rims. And if so should I get something like those plastic rims or maybe some colored rims? So far the bike has cost me zero and the parts listed above were $125. The treads were $45 apiece. I guess that the rims that came with the bike will have to do for now until I at least can establish the working condition of the rest of the bike. More updates later.
