Re: New guy from Iowa
Welcome to the forum Dave, glad you joined us.
A Motorized Bicycles is a great father son project glad to hear you and your son are enjoying it.
Without really knowing whats going on the best advice I can give is check to be sure the wiring is correct and if you are using the kill switch be sure it is not shorted out.
Hope you get it figured out if not feel free to ask. Plenty of experienced members here that are more then willing to give a helping hand.
