That is exactly what I thought it was. The wood is simply to create a shell which the builder will fiberglass over. I've thought about creating one of these vehicles for years but never had the time/money/space to do it. They commonly use a VW front end with whatever bike you can get your hands on to power it. Goldwings are often a popular choice because they have reverse. Otherwise a system, usually using a starter from a car, has to be cleverly designed to be swung out of the way when reverse it not used. That is, unless you like pushing your vehicle out of a parking spot in a busy lot. Why have I wanted to build one of these? Pure shock value and a whole lot of fun.
