There are a few....
-
the very odd tan lines - across my wrists, under my chin & my feet! I wear closed toe sandles so there is crsscross on my feet, long sleeves so I don't burn so my hands are very very brown & my helmet leaves a white stripe under my chin!
-
the desperate search for bike racks! Wherever we went, tourist infomation knew occasionally but in some towns there were none!!
-
cycle paths that trail into nowhere or to a fence you have to lift your bike over (sign actually said that) or a kissing gate that your bike won't fit through or a brick wall!!
-
wonderful 'paths' on roundabouts to follow safely on the bike
-
my period changed completely (for the better - shorter, it all comes out at once 
)
It's been fab - I honestly thought I'd buy it & it would sit in the shed, but 370 miles later & I am still loving it
