the shop i work for. but that may only apply to bikes as they are sold, and maybe not necessarily as they are ridden. all bike have to be sold with two hand brakes (sorry not rim brakes, as this would disallow any disc brake bikes, as you just pointed out), one red reflector, one white reflector, pedal reflectors (must be yellow), wheel reflectors (must be yellow). every childrens bike, even though most of them (12"-18" wheels) have a coaster brake, has two hand brakes.
