The brakes linked to are known as caliper brakes. They are made to work with cruiser bikes as they have a long reach and room for wide tires. BMX and road brakes in this style are also caliper brakes. Calling a caliper brake a "road/BMX/or cruiser" brake is just a way to make it easier to choose which caliper you need based on the application. What's important when choosing which caliper you need is the reach, whether they're nutted or recessed, and tire clearance. They all will work with MTB levers designed for cantilevers or road levers.
