awroight.Let's limit it to viable, rideable, existing dirt-worthy contraptions with pics.
I'm thinking a gearbox thread should have a list of viable and/or pretested transmission principles. many tinkerers on the wave, some may bear fruit. KeepItSeperateStoopid.
two shaft toothed cog
three shaft toothed cog
Derailier one or both ends
variable cone friction systems belts or otherwise
splitcycles with cam or crank producing easily converted linear leverage.
variable diameter chainwheel systems
variations of many of the above incorperating recyclic braking.
bet I've missed some?
