Yeah i must say im getting a little confused, i really wish they were all measured the same way.
So the modern 21" rim is the rim diameter, depending on the tyre they can end up with around a 28" OD. Right?
Most early boardtrackers came out with 28" wheels right? But thats outside diameter isnt it? The actual rim size is what again? 23"/24"?
But you say this has 26" wheels? The overall wheel doesnt appear as big as early boardtrackers? So is the 26" the outside diameter? If so what does the final rim size end up being? And why are they different on this bike? And like John said it has unusual tyres, was this a flattracker or something? Maybe smaller rims for increased strength of wheel?
I watched a vintage bike on EBay recently, im no expert but it seemed like most stuff was there to build a complete bike, and the price didnt seem ridiculous to me, if i had the money i may have considered buying it, but i dont have the money so didnt think much of it..... anyway the auction ended with no bids, the bike project had multiple wheels that he said were 26", would they be the same as this Indian?.... I messaged him to see if he was interested in selling a set of wheels, its been a couple of days and he hasnt responded.

Im going to my first ever vintage motorcycle swap meet next month and im very excited (they arent anywhere as common here as i imagine they are in your corner of the world), i will be keeping an eye out for some large diameter wheels for my BSA project. Ive also never seen a real vintage/antique bike in person. I hope they have some there as its quite a drive away.
