Having the option to quick-change gearing for a specific racecourse will be a great option. Granny low gearing for hill climbs and tractor pull competition... priceless!
Your ratio explanation was very good. I guess its a gearbox of sorts i can see the next step is designing a selector operated from the cockpit. I wondered instead of the rubber mount under the engine maybe a bit rigid and be better off with some valve springs 2 maybe in case one breaks. Also would spread load of engine. Just a thought Warwick
The jump to selecting gears from the cockpit is a pretty big leap in complexity. And to be honest, too close to a transmission (which is very much against my CK purity ethos). Just being able to do a high or low gearing for different applications is a bonus I didn't have before. All I have to do is remove one chain and put on another. Stay tuned for the testing video to see if the rubber mount works. I think it has a chance. The movement of the rear axle isn't very big, so I think it'll flex enough. We shall see!
Complex! Clever, too. Good luck with it. I'm a bit worried about the total transmission efficiency (engine-to-wheels, via multiple belts and chains and bearing) but what the heck, why not?
Yes, I don't know of any Ck that doesn't have front suspention. But few have rear suspension. Check out my "body off" tour of The Vulture for details on the front suspension. th-cam.com/video/vtUVdpWqm1g/w-d-xo.htmlsi=liy0L0ikSPQSDA2H

Ooooo, that's one I hadn't considered before. A pulling competition for Cyclekarts.
Great Vidoe. Thanks for sharing!
Thanks for watching! More to come.

I can't imagine it'll be more draggy than the smoking drive shaft from last year!
Fellow cyclekarter from Seattle here. That is a very complicated suspension set up you got there for sure. Are you running front suspension to?
