Weird bikes, bike innovation and bike contraptions

Not sure if there's a thread for weird bikes/ bike innovation. I remember reading about about this bike a while ago. Didn't have gears then; now it has. In general, is interesting to me that bikes are using essentially the same transmission method/technology than when they were invented (pinions/cogs and chain). Then again, motor bikes are the same...

I know 99% of these these things will fail and never see the light of day. Still, I like to see people try to innovate.

This chainless bike's a gear closer to revolutionizing the cycling world

Here is one I saw at a swap meet years ago, it's old, like 1909

If they put a shaft drive on a suspension bicycle, would it experience shaft jacking like motos do, or is the acceleration a human puts just not enough to have that effect? Sorta the opposite of pedal Bob. Any engineers know?

Good call. The force is "up", but I'd expect it would be far less than anything with brapp.

I'm thinking at high rpm it would be tough for this to shift fast enough to prevent damage. Notice how in the video any shifts are done at very low rpm. With a chain, during the time in between gears, the chain is sliding up the cog ramps. With this there can't be any in between, just mega failure. :p

Years ago at a swap meet in Philly, a guy let me try one of those radically slacked out chopper bikes (it literally had about an 8 foot wheelbase). Holy crap those are not easy to ride. The front wheel just wants to flop all over the place. It was quite a challenge to keep it going in a straight line. It was fun, tho.

Ever hit a jump where you land hard enough to rub the rear tire between your legs?
That's the first thing I thought of. I was like weird no dropper post... Don't want to get your squishy bits anywhere near those things.
