You will find the BMX challenge West of the hospital in Los Santos in the 
skate park area.  There is a bicycle sitting by itself there, all you have to 
do is get onto the bike and the challenge will automatically begin.  Your goal 
is to collect all nineteen markers before the time is up, many of them are 
floating in the air and require the ability to bunny hop high enough to reach 
them so if you find the challenge too difficult try increasing your cycling 
skill before trying again.  Each ring you grab adds another ten seconds to 
your time, collect all the rings before you time reaches zero.

As the name suggest you can find the Chiliad Challenge on top of mount Chiliad 
which is located South of San Fierro and is pretty much unmissable.  You 
started to climb it during the first mission out in the badlands after 
completing Los Santos.  Climb to the very top of the mountain and get on the 
mountain bike any time between 0700 and 1800.  The race is a checkpoint race 
down the mountain, your goal is to hit all the checkpoints and win the race in 
first place.  This isn't the only race however, after completing the first 
race a new one opens up on the same bike and yet another one after that.  If 
you're looking to get full completing of the game, you must win all three.

You will find this bike on the docks near the crane that you operated for the 
Wang Cars mission.  If you haven't done that yet then it's in San Fierro in 
the docks area East of your main garage.  Beside one of the large yellow 
cranes is an enclosed area with a huge pool shaped area devoid of water.  This 
is for storing ships in but it's currently empty.  Anyway not down in the pool 
area but along the side you will find a motorcycle, get onto it to start the 
challenge.  You need to collect all the coronas before your time runs out, use 
the pool as if it were a half pipe in order to propel yourself up into the air 
with enough speed and height to collect all the rings, it's not easy.
