Not sure if this qualifies as weird, but…
IIRC this shaft drive example was pre-WW I. Saw at Jacktown engine show a few years back. Pretty sure it was an FN (Belgium).

They have a reputation of being kind of wallow-y in the rear end if you gun it, but otherwise deliver the goods. Always interesting to see old machinery like that made on manual machining tools--I've got a coaster brake hub that's pushing it's 9th decade.
BTW, if you get misty-eyed, Ghisallo still makes wooden rims in the traditional style. Maybe @serviceguy can run them back from Italy 😃

Sounds like a solid plan.
Is Shimano about to reinvent the rear derailleur?
A new patent suggests a rear mech is in the works with increased ground clearance and improved wide ratio compatibility

Does a three pulley der count?

Shimano buries Suntour, steals all their ideas after they're dead.

Surprised this thing hasn't shown up here yet:
edit: didn't see the other thread, but it definitely belongs here.

She warned her family not to buy that bike, but no one listened to her.

Their pro cyclist isn't too pro eh?
Or is the fan slowing the bike rather than propelling it?

This bicycle design is based upon a version depicted in a classic Popular Mechanics magazine, and after testing, it would prove to be reasonably effective

I think that fan blade is inefficient. You can clearly see the original one has a better shape for pushing air, the recreation has a significant amount of the blade flattened out(for lack of the proper engineering term). Looks more like the governor on a wind up music box than a propeller.Their pro cyclist isn't too pro eh?

Your idea is more interesting but the pic looks like an unfinished version of this bike

While reducing one’s carbon footprint and adhering to the canons of sustainability have been thrust into the consciousness of each and every one of us, few industries like cycling have really set their goals on accomplishing that end. As a result, we’ve been treated to exotic and unusual bikes...
