A big one and a small one for 110v.
An even smaller screw-in socket for DC flashlight bulbs.
Oh, and a monster sized screw in socket for industrial bulbs.
I think the more annoying thing is a plethora of automotive light standards. There are two basic sockets from the 70's. A single filament bulb, and a dual filament bulb. But, then things have gone wild. Of course, those old circular push in bulbs always were a pain when they went bad. Also auto fuses

I wonder how long it's been since someone sold a new bike with 590 tires. This is like getting mad at Sony in 2021 when you accidentally bought betamax tapes when turns out you had a minidisc player

Recently had to go down a rabbit hole of lighting standards when a couple of bulbs in our kitchen track light started to burn out. Fun stuff!

Growing up in a farming community, there were basically two things to look for in a tire; size and Schwinn or not Schwinn. We did see the odd English variety from across the pond but no weirder French yet. Hardware stores , Western Auto for example, usually stocked replacements in a dedicated section for bicycles and the owner/ day manager usually knew their product line. Entering into the 1970s, things radically changed and fast, particularly in metro areas and college towns. Bicycling went from primarily utility and pleasure to performance or sports driven. Pretty soon it was weight, geometry, gears, and tires were changing with no defined standards other than what could hold it's place in the market the longest.

oh i got educated alright, and the class only cost me 44 dollars.
did not have to get a student loan from citibank for 30 grand at 12%
i am going to cut that tire up and use the "green guard" for a mr tuffy.
should only take me three days, two razor blades and a box of band-aids.
i knew that tire would not fit a 650B bike, just wanted to check forum awareness, sure enuff somebody caught it, full props going out!
i use to ride with a 650B guy, he led me on a street chase on the way to the single track, took me through a place on the sidewalk wide enuff for his drop bars and narrow enough to catch one end of my bull moose bars. down i went as he snickered off. smart guy, owns a winery in Los Gatos now. Rob Jensen. https://www.testarossa.com/about/
I had the last laugh, on the way home he tried to ride his 650B over a big pile of sand at a construction site. he got going full speed and as soon as he hit the pile his front wheel dug in and he did an instant flip and face plant into the pile, now his sweaty face was caked.
har har i said, har har!

My 1973 CCM with SA AW3, came with 1 1/4" x 590 mm rims. It never was a useless size, quite the contrary. It was perfect for small adults or city bikes. There should have never been all these other goofball proprietary sizes, like 571, 597, 630, and later 584.
It would have been fine with 635, 622, 590 and 559 or whatever 1930s balloon tire cruisers came with. I will always call 559 a clown size.
The 590 put downs are just laughable. Some girls size Linus and Pashley bikes came with this or 584.
I did switch my CCM to 584 x 38, no choice really.
OTOH ... Going 6 mm smaller on the rim allowed me 8 mm bigger tires, now the only good alternative for 26er road tires in 35 or 38. That could be why they started making 584.
Anyway, it's now the predominant MTB size in Asia. Thankfully, IMO.

@walmart and other big box stores in the USA, you have '26 inch mountain bike' tires - those are ISO559 knobbies. And you have '26 inch cruiser bike' tires - those are ISO559s with street tread. Aaaand then you sometimes have '26 inch road bike' tires - those are ISO590 (26 x 1 3/8, 650A, EA3). These are typically folding tires in square cardboard boxes.

In rim (bead seat diameter, BSD) size, 18" (ISO355) is larger than 16" (ISO349) but smaller than 17" (ISO369). 27.5" (ISO584) can be smaller than 26" (ISO590). 28" (ISO622) is the same as 29", but smaller than 28" (ISO635). Heads up for any bike shop employee who has someone roll in needing tires: ISO559, the ubiquitous balloon tire mountain bike size, is sometimes known as 25" in the wheelchair world. Yes, the 26" size is confusing, but pity the poor rider whose bike uses 24" x fraction tires, which might be ISO520, ISO540 or ISO547!
The ISO size (sometimes still referred to with the older designation ETRTO) is clearly the way to go, which is why the two most recent tire sizes foisted onto American riders are of course called 27.5" and 29"!

Older light truck, skidsteer, farm implements ran 16.5". As far as light trucks it's pretty much a dead size. I have a pickup with 16.5 rims and your choice for tires is 1 or 2 highway tread or $$ off road tires. If and when I replace the tires I'll have to buy 16 or 17" rims. But yeah a 16.5 on a 16" rim is bad sauce.
There are very few screw in lightbulb standards in the USA.
A big one and a small one for 110v.
An even smaller screw-in socket for DC flashlight bulbs.
Oh, and a monster sized screw in socket for industrial bulbs.
I think the more annoying thing is a plethora of automotive light standards. There are two basic sockets from the 70's. A single filament bulb, and a dual filament bulb. But, then things have gone wild. Of course, those old circular push in bulbs always were a pain when they went bad. Also auto fuses

there should one size, 26.5", that's it.
wheel chairs, cycle cross, MTB, road, TT, unicycle, BMX, recumbent, ice breakers, mechanics creepers, wheel barrows, cars, trucks, snow mobiles, they all have to use 26.5.
tires would be cheap! what about the kid's bikes? have to stay on the Flexi Flyer til age 18.

I think 635 came before 622. 635 tires were always marked 28 1/2 x 1 5/8" x 1 1/2", I rode them. So actual size was likely 28". Somewhere in the 1980s, they quit supplying 28 1/2, so my dad had to switch to the new 28" / 622. These and new 700c have an actual size about 27 9/16 with 36 mm tires. My 584 x 38 mm are actually about 26.5". They mostly come with 2" tires, so that's why they called them 27.5ers. LOL.
630 was for sure the dumbest move that came along. Schwinn sizes were likely part of their downfall.

i remember stretching a wrong size tire on a 3 speed rim, took really big screwdrivers, got it on there but it did not last long, probably about 3 miles, walked home with the rest of the undelivered newspapers,
