Very cool 4-Speed cableless bicycle.

I love inventive, offbeat solutions like this, even if they're not clearly superior to the typical way of doing things. I would love to ride it.

Hmm interesting. They make cranks like that for unicycles. I've often wondered why they don't make a CVT-esque geared hub.

They do. Worked on one yesterday.

Heavy SOB.

Probably very expensive

Dude rode a schlumpf on the divide with no issues in 2012. He's a character.

Both of those products have been around for a while. The kick back hub about 100 years. The shlumpfs Mt drive at least 20. Do you know the cost of that unit though. Been a while since I last checked, but about $500 IIRC.

True, but I've never seen them together on the same bicycle before.

And then there's the Rohloff Speedhub 14-speed enclosed gear hub. Not cableless, but a lot more choice in gearing.

Couple that with the two-speed crankset and go nuts, with no derailleurs to adjust.

Again, not cable-less, here's the Shimano Alfine 8 speed geared hub on my mountain bike right after I finished the build. (It's not so clean now.)

There is a 307% difference between in ratios between the lowest and highest gear, which is almost enough.

Shimano makes an 11 speed that has a 408% ratio range, and the Rohloff 14 speed Speedhub has a 528% ratio range.

I don't plan on ever going back to derailleurs.
