Hello all. Just completed a 24 inch cranny build for my son. I sure wish I would have found these forums BEFORE the build. Anyway he is 13, pretty small and lightweight so the cranny should be fine for him for now. I ordered a kit for myself and am having trouble deciding which bike to put the engine on. My original intention was to put it on my panama jack wally world special but after poking around in here I am kind of worried that might not be such a good idea. I am around 220LBS. My question is should I go ahead with the panama jack or use the old trek that I also have? The panama jack is pretty much brand new and the trek is not. It is complete but has been left outside and neglected for a while. I am sure it wouldnt take alot to get it back in shape. Anyway sorry if I am asking elementary questions but I have no clue when it comes to bicycles. Thanks in advance and I look forward to any and all advice.
