30+ mph! Thats tour de france velocity with a lot of kinetic energy (albeit still less than a car at 10mph I think).

Sprinting at 30mph expecally down a hill is vastly easer than mainting that for the long term.

Many of these people where not going all that fast. https://en.wikipedia.org/wiki/List_of_cyclists_with_a_cyclin...

Well, an 80 kg cyclist+bicycle system at 30mph has about 7 000 joules of kinetic energy.

A 1 ton car at 10 mph has 9 000 joules of kinetic energy, so about 30% more.
