-Clipless pedal riders are connected to their bikes by cleat and 
 mechanical "hooks".  There are many pedals out there on the market, each 
 with their own designs.  In this FAQ, I will NOT recommend any specific
 model because the technology changes too fast for me, and also it has a
 lot to do with personal preference.
-Advantages: Very solid connection from the bike to the rider.  Once the 
 rider is experienced, it will be easy for him/her to unclip.  It's cool.  
 It helps many to bunny hop (read:hop/jumps).
-Disadvantages: Cost.  Fear of being clipped in when you need to remove 
 your feet.  Must be used with cycling shoes. 
-Float is the amount of side to side movement the pedals allow before 
 releasing the cleats.  
-To engage, simply step into it and one of the hook/bars/clips will snap 
 back.  You should hear a "click" when you are in place (except ONZA).
-To disengage, twist the foot inward or outward to release, again, you 
 should hear a click (except ONZA).
-When first learning, it is best to set the pedal to the lowest release 
 tension.  This way, beginners can clip in/out easier.
-Practice on a grass field so that when you fall, you are not going to 
 get hurt.  Ride around on the grass and try to engage and disengage each 
 foot.  Leave the non-practicing foot unclipped in case you fall. 
-Do not ride on the streets/trails until you have mastered these skills.
-Turn up the tension as your skills increase.
-Try lubing all the contact points between the pedal and the cleat and 
 also all moving parts to improve the smoothness of engagement and 
 disengagement.
