Potentially deadly? Maybe, sure, but at low speeds, up to 10 mph say, it is incredibly unlikely that falling off a bicycle (even with no helmet) will do more than cause bruises and damaged ego.
Falling while stationary is the second most common type of accidental death, can't imagine a bicycle makes it any safer lmao
Is this including the elderly who often will break a hip that way and then die of the complications? Because if so, that would not be comparable to a healthy young (< 60 yo) person falling.
Are there numbers on the average height of those fatal falls? If they're from balconies, roofs, etc., I'd say being on a bike (a few feet from the ground) would make it much safer.
When you're balancing on two thin tires, you are lucky if you fall and don't slam your head on the pavement.
Curious if you have ever fallen off a bike? I have fallen over several times on a bike while stationary (when learning to ride with clipless pedals), I have crashed bikes at much higher speeds as well, and I have watched my kids fall off of bikes lots of times while learning. In all of that, I have never seen a (or had my own) head hit the ground. Typically you hit the ground with your arms (slow speed or stationary fall) or your hips, back, or shoulders (if at higher speed).
