Kind of cool looking....is it worth driving over to ride for fun? It’s on local FB marketplace. Curious how it feels.

Looks like a similar mechanism to the one CeramicSpeed is (was?) developing, albeit much more crude

Drive shaft...neat! Looks like the same model this fellow was talking about:

Shaft drive bikes have been around for well over 100 years. If the price is low enough, then enjoy it,
