I am thinking about building one of these contraptions for commuting (2 miles a day) and light erands. I see a lot of them in town and they look like a blast. However, before I jump in I do have some questions. Are these kits really "Bolt on"? What can I really expect? What is the best kit in therms of quality? What is the best style frame to use as a base? Any advice will be greatly appeciated. BTW I am a former motorcycle mechanic so I know which end of the screwdriver to use. Thanks again!
