There was a two speed jack shaft arangement that was made for go karts that offered two features, one being a second speed and the other an in/out or more correctly a low, neutral, high which could be taken out of gear underway. It did not have a way to put back into either low or high until at a standstill.
I am still looking for a good two speed trans to use as I design my three-wheeler. From a cost standpoint there are (5) speed pulls from Harleys floating about on Ebay for very decent $ but as y'all know we can probably use at most 3 speeds, but two probably are enough. I located a Pinto front suspension on Craigslist this weekend. It even has new disk pads but does need a clean-up on the rotors because it sat outside for too long and the rotors are kinda ugly. I need to do some clean-up on the frame components, I think I am going to drop the anti-roll bar because the overall vehicle weight will be in the 12-1400lb range, very low cg (achieved through low battery placement and low perimeter frame components... high frame components will be more like a bird cage design.
