"After a night of drinking, my friend thought it would be a good idea to go down the escalator with his bicycle," says YouTube user Pr0uditalian, posting the above footage shot at the Pacific City shopping mall in Huntington Beach, California.
As the video shows, it wasn't so much the ride down the escalator that caused his pal to come to grief - rather that no-one had employed sufficient foresight to work out he'd head straight into a glass wall when he got there.
Not one to try at home ... or indeed at the Trafford Centre, Bluewater, Westfield Stratford City or whatever your local shopping centre happens to be.
Born in Scotland, Simon moved to London aged seven and now lives in the Oxfordshire Cotswolds with his miniature schnauzer, Elodie. He fell in love with cycling one Saturday morning in 1994 while living in Italy when Milan-San Remo went past his front door. A daily cycle commuter in London back before riding to work started to boom, he's been news editor at road.cc since 2009. Handily for work, he speaks French and Italian. He doesn't get to ride his Colnago as often as he'd like, and freely admits he's much more adept at cooking than fettling with bikes.
