Does this have the weld on stand or bolt on type? Are the wheels S2?

The frame has a welded stand, barely visible in photo #3 (my #1) and more so in #1.
Rear tire in photo #1 (my #2) has a Kenda 20x1.75 tire so I would assume S-2 wheels
The fork definitely looks S-2 though.
Hpoe this helps until you hear from the source.

After looking closer at Photo #1 I was able to make out the size on the front tire as 20x1.75, so both wheels should be S-2 since as you know S-7 tires are marked fractional (20x1-3/4) as an example for others reading this that may not know.
Hope this helps you to buy it. I would if I could but too many as it is and not enough time or money to do them (althougth that has never stopped me before).

Yes the stand is welded on, I couldn’t find any markings on the rim.

I was not sure if they were marked back then.

The Kenda tire should have the European (ISO) sizing number next to the 20x1.75 number probably in parenthesis. That will tell for sure, but 20x1.75 has always fit the S-2 rim.

If you can find the numbers next to the standard size markings and snap a photo of that I will look it up and tell you for certain.

If there is no number, measure the diameter of either rim (straight across the circle at the widest point) or even the radius (from the axle center to the outer edge and I can tell you from those as well.

I can say that if I were able to buy this bike, wanting a 20" balloon tire bike the evidence that they are S-2 wheels would be good enough at rhis point to buy it.

I almost wish I could, but I am not able to this month since my Toro Z Master took a dump on my lawn and I am north of $300 putting it back together. I do some mowing for my neighborhood to suppliment the family table, which are code words for OBD (Obsessive Bicycle Disorder) so the mower has to come first.

Every time my wallet gets a monetary distortion something around the house feels neglected and breaks just so I cannot buy another bike part I do not need (but want badly).

Or am I just Paranoid?

Hope this sells soon before I have to sell the pitiful remains of my soul to buy it myself.

For the tech gurus here, my method of measuring the rim in the last post I made would not give an accurate ISO sizing. It was meant to simplify the measurement for me to check against my 20" rims to post the correct rim size here.

The correct method, which is measuring from bead seat to bead seat cannot easily be done by the average person and is much harder with the tire on the rim and mounted to the bike.

You could also measure from the bottom of the bead on the tire to the bottom of the bead across the wide point but that requires the tire to be off the rim as well.

Below are the ISO (International Organization for Standardization) tire sizes for the common 20" tires.

(Who came up with ISO as an acronym
for The International Organization for Standardization cannot spell an acronym very well but that is most likely a European situation.)

Be happy to help with anything I can on this subject.

406; Standard S-× rim ISO marking
419; Standard S-7 rim ISO marking
451; Standard S-5/S-6 rim ISO marking

Thanks for all the information Rob, and good luck with your mower

No problem man, thats why I am here. Sure it's all fun and games until someone blows a tire, but thats when it's time to get out the patch kit and help fix it.
Hope my luck holds out on the mower. So far this should be the last problem. It was running last year when I changed the engine so it should've been running now but after finishing it up it still wasnt happy with how much attention I paid it.
Thanks, Rob
