I've been on two wheels long enough and have enough titanium in my body to know this shit really does happen

I can imagine handlebars breaking or a wheel suddenly coming loose or a mechanical gearshift just ripping off because you were a dumb teenager and didn't realize that switching while going uphill is a bad idea. (had the pleasure of the last two)

But seatposts "apple-coring" riders through the saddle? What?

Or the chain springing out of the gear just while you're climbing uphill on the wrong side of a road next to busy traffic, and the sudden jolt throwing you off balance and making you sway into the traffic?

I have lost a chain twice on motorcycles! Can definitely be sketchy if you don't react immediately.

And the seatpost thing is one I've heard about - IIRC Peloton had to recall several million stationary bikes because of a similar failure.

Ouch... wouldn't have thought, but thanks for telling.

I had a crank arm snap in half as I was powering up a hill. Got so thrown off balance, I crashed into a parked big rig. That was the lucky outcome
