I think it was a dutch or german company, they were a variator that had the ability to shift by pushing a button.
I remember watching a video of it, and finding a few old articles about it, it's pretty old probably early 2000's.
Just trying to remember the name of the thing so I can show someone else.
I have googled the hell outta it but no luck

Pito; Are you talking about specific ratio shifting? There are many videos regarding 3+ kw electrics with CVT's, but shifting? I saw a road bicycle that had a shifted front sprocket...telescopic gear system with fixed rear gear. The older hybrids use a "shift" system where the engine provides power to a certain (fuel efficient) level and then the servo brain kicks in to each wheel, giving needed torque. Those can be selected. I think the Smart cars in Europe used a shift system to engage specific ratios. I drove one with a diesel, not a hybrid, but a CVT..maybe called an EVT? It was a 6 speed, but the tranny was sort of a hybrid. It had a conventional gearbox, driven by a servo controlled belt and clutch system. German Getrag...the Smart was/is a Swiss/German company owned by Daimler-Benz.
That may not be what you are looking for. The Smart cars had many different drives, plus the new E-version. The original car was early 90's, however. I drove one, a rental, from London to Wales on the M4. Surprisingly fun, even with lorries passing. (big rigs)
Interesting!! |

No this was an add on variator to your typical piaggio or minarelli that allowed you to "shift" via 2 buttons up or down.
It was kinda gimmicky and didn't really work well from what I read. But made your scooter sound like a shifty.
