I was thinking of mounting a single sprocket to the driveshaft and running the chain down to the mainsprockets on the rear axle and making the derailleur work for it insteadjemma said:Do you mean a shaft with the cassette on it and a single sprocket at the back?
That would actually make more sense than the usual way because the change is nearer the motor and torque source and you'd get less trouble from the chain such as it jumping and such.
Im interested in seeing what you come up with on this
Its doable, but not easy to set up because you would end up with duplication of ratios if you werent careful - let alone the other logistical bits and pieces with the controls and such..hmm, or even a cassette on both ends and two derailers! That would be an interesting one. Get a whole boatload of gears that way, lol. Ok yeah, I'm a little nuts
I hadnt thought of a clutch... Hmm that throws a bit of a wrench into it. I just want to be able to go and possibly shift on the fly.deacon said:Anyway keep us posted I'm curious to see how you and racing do with the build. You do know you are likely going to need clutch of some kind, unless you can drag start the engine at every stop sign. I did that with a 25cc engine and it was fine as long as the stop sign didn't leave me with an uphill start.
