Hello, names David and I am very new to this hobby, I actualy have not built one yet. I am planning on it in the next 2-4 weeks. I find the motorized Bicycle a very interesting idea although I wonder if one can go faster than 40 miles per hour? anyway I live in Little Rock Arkansas, married, have two great kids one close to moving out, if I can let her. I am 40 years old and hopeing this will prove an interesting and practical project.
