Do you ride BMX competitively?  The X games are in early August this year.
No i do not just for fun, how abput you
I do not ride bicycles.  Do you have a favorite BMX rider?
No i do not i prefer to ride not watch
I see, well BMX stands for bicycle motocross, presumably derived from the motorsport of dirt biking, as bicycles do not have engines.
Ah yes it is all human power
Yes, bicycles are powered via users who press their feet with force against a pedal turning a crank attached to a sprocket via a chain.  The sprocket is attached to a rear wheel.  As the person applies force this is turned into rotational energy transferred through this system to the back wheel providing forward motion.  In a scenario where the sprocket is fixed and not free it can also produce backward motion.
