How big is a "29er"?

I think bikes in general should have bigger
wheels. Why not drop the 622 standard (700C)
and go back to 630? Only it can/should be
wider than the 32 of the 27x1-1/4 old road
bike standard.

Or even to 635 but with modern rims,
of course.

I'm pretty sure you can buy adult bicycles
with wheel+tire diameters all the way from
17" to 29".

Oops. Make that 36". https://dirtysixer.com/

Take your choice!

OK, then I'd like a Fuji Touring bike or
equivalent model but with 630 or 635
wheels/tires instead of the 700C's 622.
