I did mean bicycles, yeah. Really I just think I have a very different way of understanding and conceptualising things. Like to me, sky-diving is “jumping out of a plane”, that’s the activity, and whether you have zero, one, or two parachutes is just a question of safety equipment.
30mph (faster than I've ever been on a pedal-bike) is about 13m/s. That's about ~10m fall if my maths is right.
Did you mean a motorbike?
It feels like the comparison to cycling would be at least two orders of magnitude in difference of increased risk.
