Skinbike 

Quite literally a bicycle made of skin but used to describe the act of lovemaking from a competitive, sporting or aerobic perspective. The word can be used to describe the object of a sexual pair, including but not limited to women mounting men and riding them like a bike made of skin. An alternate usage can include a sexual pair who agree to collectively "ride the skinbike."

Woman: "I'm dehydrated from riding the skinbike last night"
Friend: "He's a real Lance Armstrong eh? Making you sweat?"
Woman: "Girl, if you aint sweating after riding the skinbike, then you're doing it wrong!"
