Does anyone have tried to use a bicycle transmission for a multi-speed mechoui ? Answered

I have an AC motor at 4RPM and I do not want to change the sprockets manually each time to change the speed. I would like to have a mechoui (bbq) which allows to have the following speeds: 4, 6, and 8 RPM. I think modifying a transmission of a bicycle: to change the speed I would just have to actuate the handle. What do you think ?

Ceratinly possible but two cones that you push together will change the ratio as well and might be less hassle to build.

I'm interested, do you have a draw or something ?

Just check how a scooter transmission works ;)
And instead uf using centrifugal forces and weights to push the wheels apart make it adjustable by screw or bolts...

It seems more difficult to build than to machine new gears to remplace the gears in an 3 speeds bike gear...

DU means something like this. Click to see full size.

Remember a standard 3 speed bike gear will only give you:

1:0.75

1:1

1:1.25

gear ratios.
