Want to put folding pedals on kid's bikes-Advice

Here's the issue, kids bikes; 14", 16", 20" bikes with one piece cranks have 1/2" spindles.

Without pedals (or with folding pedals) these bikes basically lie flat. (BTW, I also turn the handlebars 90 degrees).

So,
Do I tap from 1/2" to 9/16"? --- 9/16" folding pedals are cheap/available. Have not found 1/2" diameter folding pedals.

Try the adapters? --- 1/2" - 9/16" , but then it expands it another inch?

Disassemble pedals? --- And hope I don't strip it or forget wrench and I have to be there.


Anybody been there, done that?

I think the reason for the persistence of the 1/2" pedal size is that the crank size is tight for making the turn to install/remove. Although 9/16 really isn't that much larger, but I'm not sure I'd tap the larger size.

When packing in general, the pedals and perhaps wheels should be able to overlap a bit. However, if this is a rare tight packing for a vacation or something, then I'd just pull off the pedals.

A couple more details of why you want to flat-pack the bikes might help with the most effective (time/cost) solution.

If this is for a one-time shipment or long-term storage, i'd take them off.
I mean, you're already disassembling the handlebars/stem, someone with tools will have to be there when you unpack these bikes.

IMHO, the hardest thing about changing pedals is taking them off the first time. I have a couple of bikes i regularly switch pedals on, put a little PTFE thread sealer on them to keep the threads lubricated (it's less messy than grease or anti-sieze)

If you're concerned about cross-threading, most pedals are usually marked 'L/R', or you can accomplish the same thing with a paint marker on the end of the pedal spindle.
If you're shipping the bikes somewhere, or storing them, secure the pedals to the bike (under the seat works well) with a zip-tie or a twist of wire, so they don't get separated.

Lookee, Lookee what I found, purely by accident.

https://www.ebay.com/itm/PVC-Folding...0AAOSwXgxcWcEx
Here's the description;

This will fit 1 Piece cranks.
1/2" Axle. Will not fit 3 Piece Cranks.This is the smallest size axle.Sold as a Pair. You get left and right pedals.Also note, Good advice Ironfish. Thank you. But when I'm moving or storing in garage, I don't remove the handlebars, I just loosen the stem and turn 90 degrees.

If you go with one of the bigger, more solid folding bikes you can use a standard child seat. With most smaller-folding bikes you'll run into weight limits even if you can get one to fit - they're often only rated for 90kg or so, which means that even a light 60kg adult and a 10kg child doesn't leave a lot of margin for "it wasn't designed for this" stresses.
