Bike.

I've mastered the art of riding a bike in 4 inch heels.
I can even ride in skirts without flashing my garters.
I can go up hills, bumps, curbs, and even had a brief...perilous moment with mountain biking.
But somehow, I can never manage to keep from running into my pedals when I'm walking the bike. I always succeed in scratching up the backs of my legs and destroying my stockings in the process.

Tricky tricky
