AutoStream SmartShift 2000 automatic bike shifting system

Thanks for showing how this works. I bought my Mom one of these and she only used it twice because her balance wasn't good anymore due to age.
Do you know how much a mint AutoStream is worth today? 2021?

too much pedal rpm to shift, it should shift earlier

I know this video is a bit old, but do you have any thoughts on where to buy a spare belt for these?

The wheel wobbles like crazy, did you notice that?

will that hurt the derailer by having it in 6th gear and not pedaling..i would think over time something will break

Este sistema de cambios no parece efectivo para la ciudad. Tardó mucho en bajar de un cambio suave a uno duro. Costaría mucho esfuerzo salir de un semáforo hasta llegar a la velocidad crucero.

Hello, sir, I am a mechanical engineer and I had chosen the project of auto stream shifting for the bike so I want your help to give Information about your mechanism...

I just bought one of these yesterday at a yard sale..I'm anxious to try it out.  Right now it's soaking in penetrating oil for a few days,  Is the 2000 the year they were made ?  Were they made for more than one year ?   Thank Yoy for posting this !
