Twice for me.
First time in 'The Great Profanity Incident' on a wet night in Darlington, when I broke two tyre levers, skinned all my knuckles and taught several onlooking urchins some new and 'interesting' words!
The cause? A Marathon+ punctured on a broken bottle that eventually came off the rim at home with the aid of a very large metal motorcycle tyre lever and wire cutters, with, sadly, even more profanity.
The second was caused by a broken seat frame on my Kettwiesel trike, rendering it unrideable.
This persuaded me to join the ETA who recover cycles, and recumbent trikes.
