It was when I was in college and got my first apartment but still had no car. I though, "better get a bike" to make getting around town easier. I knew about electric hub motors and was originally set on using one of those, but after shopping around for a bike at the local bike stores, one of the employees there suggested an engine over a motor because electric hub motors were still way to expensive to be worth the money. I discovered this forum and bought my first kit. The rest is history.
