Nope a 12 speed bike still has gears. There are no gears in a CVT just cones. As the cones move, the belt slides up one and down the other varying the ratio.So is a CVT something like a 12 speed bike chain? but not as clunky?
CVT is a really cool concept that never -quite- pans out for higher output applications. The Fiesta and Justy go back to the late 80's, but that was behind anemic engines. And Audi jumped in with performance applications quite a while ago using a chain based system. It just doesn't hold up all that well so far outside of high efficiency/low output use.Nope a 12 speed bike still has gears. There are no gears in a CVT just cones.

That's cause the ECTV uses wizards not cones.I don't see no cones, Kenny?

I have a CVT in my Polaris ranger and while I can't say I really like how it operates it has never let me down. There's also a CVT on the head of my Bridgeport mill which is awesome since you just turn a handle to move the cones and adjust the speed. The concept is solid, like you said though I have yet to meet one put in an actual car that isn't just a massive headache.CVT is a really cool concept that never -quite- pans out for higher output applications.

Snapper has used this system on their lawnmowers since the 60's.CVT is a really cool concept that never -quite- pans out for higher output applications.

A few years ago I got to see a whole different kind of CVT in a car at the Fountainhead museum. The 1907 Cartercar had a handle that the driver used to slide the friction surface across a flywheel with a pedal engaged to separate them. Release the pedal with the friction surface on one side of the flywheel and you're moving in reverse. Slide it across to the other side and you can progressively access higher speeds depending entirely on where you position the friction wheel.
