Can you help to identify these frames, bikes or parts?

No idea, but I would certainly recommend a rear carrier just in case you slide off the saddle.

lol, thanks, im not riding the bike yet, the saddle is just placed on for now, still needs a few things before its ridable.

Hi, I'd like to invite you to the group "Weird objects used to prop up your bike for a photo and so that it doesn't fall over".com

on flickr I think I actually will start this group as there is loads of contenders for the top prize.

invite me if you make it then haha
