Everything you have said is correct, except for the beardOh TVC
So ( )
when @potsy "turns the wheel around" it is a single speed freewheel (so his little spotty leggies are not turning like whirlwinds downhill)
whilst yours, does not turn around and is not freewheel it is fixed and your long manly leggies* pedal downhill like the strong manly wind? You have grown a beard and now carry a satchell?
(*Disclaimer: I have to say that after my 4 y/o daughter subjected TVC & Lu to an account of what happens when you eat sweetcorn)
I'd forgotten about the sweetcorn
