Silverbear,
Did you manage to find a solution for this?
Yes and no, since it is a long range project I won't begin on for at least half a year and perhaps even a year from now. I have a totally different project I'm working on right now (Silverbear's Worksman Cruiser) which involves some new territory for me and after that a 1950 Panther which will get a four stroke engine, another foray into something new and different as I have only done 2 stroke builds so far. I'm not like some of the creative geniuses here on the forum. I'm no mechanic, not an engineer and don't understand some of this well enough to innovate. I am handy and enthusiastic with a good deal of time on my hands as an elder, even if sometimes I don't have the energy to use the time well. I am also trying to do too many things with too little money, but having a great time. I ask people more clever and knowledgeable here for advise and am always gratified to find teachers willing to share what they know.
So that is where I am with a three wheeler. I know I want to make one, perhaps for others, but certainly one for myself. It doesn't take a great deal of imagination to see that in ten years I may need one if I want to ride. And I have a driving interest in sharing the fun I've had with other elders who may think their lives have passed them by and they are too old to ride a motorbicycle. Having experienced some disability in my life (partial paralysis, traumatic brain injury from a lightning strike) I would also like to see the joy of motorbicycling extend to the borderline disabled, making rides as user friendly as I can. It would give me a lot of satisfaction to help someone else, as having the wind in my face on a motored bike has helped me.
Call it "research and development" if you will. All who have contributed to this thread have expanded my understanding of what is possible and now I have some ideas on how to go about it. A few weeks ago I didn't even know a conversion kit was out there, let alone that there are different options. I'll be watching other people's builds closely and asking more questions. By the time I begin I will have set aside the frame I intend to use (right now I'm partial to a 1940 Schwinn "The World" step through cruiser) and will have wheels set aside for the build and will already have a picture in my mind of where I want the build to go. All the good fellas here will have smoothed the way and given me the confidence that I can do this new thing, too.
So that is the long winded answer to your question... "yes and no". I'm still learning about it. How about you? Is this something you want to do?
