A Bike Pikey is someone that is unwilling or unable to own bike components of any significant value. Usually due to a lack of understanding or appreciation of the actual mechanistic or engineering properties inherent in most expensive items.
Bike Pikey's often feel it necessary to criticise those who can either afford or appreciate expensive, top-end components.

When a man pulls on his foreskin, creating an air tight seal around someone’s bare asshole, then harvests the fart and replants it into someone’s mouth.
I was supposed to meet Tyler for a drink but he couldn’t make it. He thought ass-to-mouth was the worst bet he’d ever lost until Dylan introduced him to the Norwegian bike pump. Now his tires are flat, his ass is raw, and his breath smells like shit.

When someone is on a bicycle he doesn't have to follow the laws of traffic, until he gets into an accident. From the second before the collision until the second after he becomes a vehicle and suddenly all laws of traffic apply to him. This phenomenon is up until the time of writing only been observed when the cyclist isn't breaking any laws as a vehicle.
person in car: "Hey dude why did you drive so recklessly?"
person on bike: "It's okay because I wasn't a vehicle until you hit me, so you are the bad driver."
person in car: "Ah I see, the quantum bike phenomenon. I was clearly wrong here, sorry for the inconvenience."
