CW has been working on a crazy thing for awhile, not exactly what I'm going to do but it gave me an idea. But I'll give him all the credit cuz idgaf.
What if, what if.....
What if one were to use 2 short belts on a hobbit or Vespa, with a 1:1 dual sheave pulley bridging them together in the center.
Then that pulley can be shifted forward or backward to manually control shift. It's so stupid and simple, but it's genius.
Push double pulley forward, rear belt drops into the rear and raises in the front. Push double pulley backwards, belt raises in rear pulley and lowers in the front (downshift)
Only issue might be belt alignment but these V belts can take quite a bit of misalignment before destroying themselves.
The best thing is that there's no belt on belt bullshit like the last one I made. That was dumb. This shouldn't wear the belts too bad, and might just give me the manual control I've always wanted, and can run a crazy weak contra without dropping rpms. Then when all is said n done, I can add my variator brake to the unit, allowing it to lock it and dump it. So fun.
Going to run 1/2in belts to start, as they're easy to find in different lengths and will require less misalignment.
Part is ordered, now I just have to get it and build the mechanism.
And derbi lame-os can't do it haha cuz there's no room. Suckers.
Anyways, boom (edited)
