The top image I saw a few years back, and it keeps popping up here and there. I always wondered who the rider was and where it was taken. Turns out it was a man called John Bange from Australia, who happened to be this cycling hero captured on film and unbeknown to me an early aviation hero and all round pioneer. Thanks to Bristol Cycle Festival and Velo Aficionado for bringing this little mystery to light and getting John Bange the credit he deserved. More info here and here.
