After Mark Schaaf voiced the concerns he had about the using the python drive train on a tilting trike, Jetrike has been somewhat redesigned. This has left me with the remnants of the Python drive train I had already started constructing, so rather than let it go to waste, I have designed a python frame to use it (Attached Photo).
The plans on my web site http://jetrike.com/plans.html are only a preview, I haven't finished drafting them up. It has a 20" front and a 20" back, elastomer rear shock, M12 rod ends for the pivot and weighs in at 6kg minus the seat. The specs are 1100 wheelbase, 60° pivot, 270mm negative tail, 240mm seat height, 380mm BB height, 410mm BB-FWA.
The thing I haven't had a response about is what the best sear angle should be, I set it at 40° for now... any ideas?
