What makes a BMX bike different from a regular bike?

BMX bikes are designed for a specific purpose, to explore your surroundings be it a race track, an off-road trail, a set of dirt jumps, a skatepark or the street more generally. For most of these purposes, tricks are involved, as well as short & sharp bursts of speed. As such, BMX bikes differ from regular bikes through having a single gear, a low frame, generally 20 inch wheels and no suspension. BMX bikes are often lighter and less expensive than regular bikes - however this may vary depending on your situation.
