This is part of my 40 Before 40 Challenge.
I’m not entirely sure what % of people can do this, but plenty of people are shocked when they find out that my sister and I can’t ride a bike with no hands. I think most who can do it usually learned when they were kids, which makes it more surprising to hear we can’t. To be honest, I can’t really remember ever trying.
Anyway, I’ve recently bought a bike (the only way to travel in Cambridge), so that feels like half the battle. Also, the nonchalance of some cyclists while doing this makes me think it shouldn’t be too hard to get the hang of, but who knows.
On a sort of related note, check out this Smarter Every Day video about riding a “backwards bike”:
