Here are some pictures of my motorized rat bike. The bike started out as a trash day find. The bike is on old rusty Murray bike that I saved from the landfill. I added a bike motor from Kings Motor Bikes. I have built several motorized rat bikes. This one will do 30 mph. If you take the baffle out of the muffler this bike sounds like its some kind of flat track motorcycle! I have ridden this bike so much that I broke the top tube from the head tube so I had to re-weld it. I have a friend who inspects welds for Naval ships and when he saw my weld he did say that it was the ugliest welding job that he had ever seen in his whole career of being a welding inspector!!! I tole him thanks for the compliment! I put red brick old style tires on this ride. Devil Horn. Steel rim in the back and aluminum mountain bike box style radial laced rim in the front. Gotta have mudflaps! This bike scares small children. Night view of the devil at a yet to be opened Wawa gas station. Rear view. Rear fender view with appropriate decalization. Motor detail. Nice foam rubber air cleaner forced to fit. Another view of the devil.
