cool always like to see a horde of bikes.
I had a 24" wheeled folding bike. Got it at the Auction
It had the fat 20X175 tyres.
I got it to use the wheels on my Raleigh Phaser.
But the bike was too good condition, so I sold it for 5 times what I paid for it.
I managed to fit a 26" 559 wheel onto a shopper, with a 26X 1.5 tyre and a 7 speed block.
I removed the brake bridges. Never built it up tho.
The BB height was very high. Would need frame mods.
