Alright, you need your feet to be attached to your pedals. You don't wanna be going down a hill at 30 mph, and lose your pedals. It's really not safe... It gives you more control of the bike.

The other benefit of clips or attaching your feet to the pedals is that you pull back up on the pedal on the other half of your stroke - it's more efficient.



Now if you wanna use grips to hold your feet to the pedals or clips or bmx pedals or something like that... They work too. Just depends on what you're comfortable with... you also can't bunny hop without attaching your feet.
