I should have clarified. I didn’t mean motor power. These are power levels needed for any average bike to maintain this speed on level ground. You and your friend would definitely be hurt the same if you both went 45kph and fell the same way.
Speed is kinetic energy, and that’s the real worry when crashing: if that energy goes nowhere else, it goes into the fleshy human being.
100% and you can estimate how much kinetic energy is stored by looking at how much energy is needed to maintain that speed. Can use bike sim to get the numbers. And as you said - that’s the energy that the meatbag would have to dissipate. The real interesting part which isn’t obvious to everyone is that the energy grows exponentially with speed due to air drag. So falling at 40 hurts much more than 2x than falling at 20.
