Tour De France Mystery Future Champs ?

I spotted this trio of tiny bikes on returning from the cafe
Such bright colours caught my eye as did  three steps , three verticals from the hand rail and then three words sprang to mind ,Tour de France . Who knows what level of sport the tiny riders of these will achieve.?. We shall never know.  There is the mystery.Macro was not needed but tiny these are and size as they say is relative .
