The question is what the definition of a "vehicle" is and then does the applicable laws apply to bikes. It seems that bikes are not defined as vehicles, but there is a specific provision that bikes are subject to the VC. Please see the following.
670. A "vehicle" is a device by which any person or property may be propelled, moved, or drawn upon a highway, excepting a device moved exclusively by human power or used exclusively upon stationary rails or tracks.
