Hi like I said I'm Larry and I build custom motorized bicycles and tricycles. I have done a couple of both and they all have pretty regular. I enjoy building these bikes, I have COPD and Asma and that is how I discovered these bikes because I love riding bikes and even more so now that I have grandkids. I'm glad to have found this site because I don't know all the answers as I'm sure most don't but if we all know a little bit then I'm sure we can figure it all out. Hope to talk to everyone soon.
