If you've ever gone on club rides as a beginner cyclist in North America, chances are you have heard of the ABC Quick Check. Not sure whom to credit for its original composition, but I'll quote the League of American Cyclists:
A is for Air,This mnemonic is meant to encourage riders to get into a habit of performing a basic safety check on their machines before setting foot to pedal. But how many of us actually perform such a check? It took a rather disconcerting incident for me to realise that I do.
B is for Brakes,
C is for Cranks and chain,
Quick is for Quick releases,
Check is for Check it over.
