You say need 2 other attach?
I'm thinking what you are talking about is the upper connections to the bike? What I see so far looks very nice. Obviously you have access to some good machine tools and skills. My only question would be the size of the axle. As it is supporting the wheel from only one side it needs a bigger axle than a bike where it has support on both sides.
Also might want to look into putting a motor in the bike, B.C. is a long way to push an outfit!
