Hello, My name is Paul. I have already built my bike but thanks to this site I know what to fix first. I have already put at least a 100 miles on it. So far I love it I average about 18 mph but I make it to work all of ten minutes later than if I drive my truck. Now for my bike I used the cheap mountain bike from Walmart although it wasn't a great idea but it works so far I have only put $300 into it. The picture I attached is an older one so please excuse the excessive chain slack.
