A few days ago, by chance on craigs list, I became aquainted with the existence of engines currently available for bicycles, facinating. As a youth in the mid 70's I raced BMX in AZ. In the late 70's I custom built one of the first "Mountain Bikes" on a prototype Voris Dixon frame. This bike was sadly stolen from the barracks at the Mare Island Naval Shipyard in Vallejo, CA in 1985. Reward if found
My intent is to go with a Honda GHX50 mated to a GruBee gearbox and mounted midframe on a Worksman Newsboy bicycle. It seems that rear sprocket mounting is a developing technolgy. I've found hubs online that eliminate the "sandwich between the spokes" mounting option. I would really like to find or develop a rear drum brake compatible method. Still researching the possibilities but will most likely have to go with a coaster rear.
After research it also appears that kit & gearbox availability is scarce and that there are quite a few dissatisfied customers out there.
I currently live in Wisconsin but ply all of the Great Lake states as Capt of an EPA research vessel. A motor bike is going to be very cool to have onboard.
To the providers of this forum Thanks.
