OK, I know these aren't actual scratch builds...yet, their a few ideation sketches I came up with. But hey you gotta start somewhere before you start cutting and bending pipe. What do you think?
The last one, first unique thing I have seen in a while is the reverse bend fork. Take this design intent and build around it. One continuous flow from the rear dropout to the fork tips.
I think the top red sketch (shows a 56" wheelbase) is an interesting concept. The bottom-bracket at the front end of the swing arm! How ‘bout a coil-over shock or air-bag between the BB and the bottom tube? :idea:
