I wrote the author a letter, asking to explain the physics behind a freewheel stopping you from gaining to much speed.. Here's her reply:
"If you're pedaling, you build up more speed than if you're coasting. That's the physics behind it. If you're braking or pushing back with your legs that's obviously different--I was comparing the ability to coast to the need to constantly pedal. "
Wha? ..umm thanks Erica.
I agree that Bryce's death had ZERO to do with the type of bicycle he was riding. RIP.
