yeah. i use brakes. that doesn't mean it's easy to spin though.
the point of oh **** is the point at which the momentum of the bike combined with gravity are exherting more of a force than your backpeddling muscles can with fine motor function and you have to use power to slow your spin.
it's not really a physics thing it's a psycological/chemistry/biology thing. and it all goes away with a nice brake.
