R 20 on 507 wheels ?
Greetings fellas
Believe it or not, in the rear triangle of the R 20 can be assemble a 507 mm wheel. This rim is a good candidate

If you want to install a front wheel of the same size, you need a 24" fork.
Now the question is where to find a 507 high pressure tire.
your opinions about this issue are welcome.

Schwalbe has some. Their Marathon HS 308 tires go up to 100 psi. Are you planning on doing this? Please pot pictures if you do. My kids bike may be in jeopardy!

caotropheus, it seems like you're saying this can be done without moving the brake bridge and chainstay bridge? Serious frame-works would make this a no-go for me, but otherwise, it sounds VERY appealing.

No, at least on the rear triangle you do not have to move the bridge. After I assembled a 24" cheapo wheel on the rear triange on the middle on the dropouts, there were still 4 cm for the brake bridge. Therefore, you can only assemble a skinny tiye on such wheel and to remove the wheel from the bike, you may need to deflate the tyre.

Hmmmm. My eyes will therefore be open for a 24" fork with a long steerer. 24" wheels, an 8 speed hub - that could be a mighty fine bike, though it still wouldn't fold very small......
