Fortunately there are no documented cases of a squirrel ever having jumped into a wheel
You are mistaken. I saw a pic of exactly that, many years ago — was in Murica. Bladed radial spokes too! Not sure how the rider fared, but the squirrel was totalled.
Ride a lap of Kent yesterday. Bit of a sore bum today. Unfortunately ran over a squirrel. Grateful it didn’t jump in to my wheel!
