I'm all about the e50s and am a super noob to variators. I totally get how the variation part works, but I've never gotten very intimate with any variated bikes so I have a couple questions.
1) How does starting work? Do all CVTs have a centrifugal clutch, and a lever on your handlebars somehow engages it to turn things over, just like on an e50?
2) What is the gear ratio range on some double variated setups? Honda, Vespa, Derbi... Just from looking at pictures it seems to go from about 2:1 to 1:2. Maybe 2.5:1 to 1:2.5?? Like if the variator were stuck in "low gear" (low speed) what would the final drive ratio be around?
3) If (extra hypothetical) I were to try to copy a Derbi transmission, where would I get the boxed things in the picture, including the clutch bell? It looks like the variators sold on treats are like only half of one of those.
