Scraper Bike (n.)- 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.
