Scraper bikes are the newest Hip-Hop craze that has its roots in the Bay Area of San Francisco. The Urban Dictionary defines scraper bikes as:
1. A relatively recent phenomenon from the Bay area (specifically Oakland) in which people modify bicycles to resemble (either functionally, aesthetically or philosophically) the famed "scrapers" of the hyphy movement
Hyphy means to act crazy or stupid. Hyphy is the bay area's answer to South Central LA's Krump. When you ride your scraper bike you should be hyphy "retarded"...
2. A new trend that is a part of the San Francisco Bay Area Hyphy Movement in which people ride their tricked out bikes and go stupid, dumb, retarded while on their bikes. Generally, the bikes have nice designs, such as duo-tone paint jobs, and rims or spinners. The term was coined by the rap group Trunk Boiz of Oakland, California.
Maybe it will catch on here.... the "coconut scraper bike"... what say?
