Pedal strikes occur when you are pedalling through a turn.
You need to be going at a pretty good clip, you need to be pedalling or to have the pedal at its lowest reach, and the turn needs to be sharp enough so that the bike leans to the point where your pedal strikes the ground on its rotation.
That happened TWICE on the P2 loop this morning.
What is a pedal strike like?
Well, each time it instantly lit up my neurons in a way that I can only describe as both unwelcome and scary.
Fortunately that's all that happened.
My fear is that the pedal could lift the bike when it hits the ground (in this case concrete) throwing it off balance and causing a crash.
That has never happened to me, thank heavens, so I can only imagine what that crash would be like. But it would be in a turn, at a pretty brisk speed. It makes me cringe thinking about it.
Of course the prudent things to do would be a) to slow down, b) make sure that the pedal inside the turn is fully raised, in this case, it's a right-hand curve, so it's the right-hand pedal, and c) watch those tight corners.
I suspect that the actual risk of a crash is less than I fear. I have seen Vespa motor scooters being ridden at ridiculous speeds along tight and winding roads with showers of sparks when the center stand or side-stand scrapes the pavement. Vespas seem unperturbed and un-inclined to crash.
Speaking of Vespas, I have had my side-stand scrape the ground on a tight left turn. It feels just as awful as a pedal strike.
