No, the Neiman Marcus Clockwork bike is not a superbike. The Neiman Marcus Clockwork bike is actually a limited edition luxury bicycle created in collaboration between Neiman Marcus, a high-end department store, and renowned British bicycle manufacturer, Moulton. It is designed for urban commuting and leisure riding rather than high-speed racing or performance-oriented riding. While it may feature premium components and unique design elements, it is not classified as a superbike, which typically refers to high-performance motorcycles or bicycles built for exceptional speed and performance.
