Pedals - you can install them, but you need a pedal wrench. Other tools don't work as well (or at all sometimes)

Cleats - they need some adjusting, it's usually pretty cheap to have it done at by your LBS - I think it cost $5

Clipping/unclipping sansa bike - DON'T TRY IT!

I tried this, put the clips on the shoes, held the pedal in one hand, tried a little clip/unclip action - I could NOT get the shoe off the pedal! A male friend of mine could NOT get the shoe off the pedal! I had to take it to the LBS where they laughed at me while they pried it off with a giant size screwdriver and the help of a vise.

What comes off easily with a little torque when the pedal is firmly in place on the bike doesn't work so well when you're trying to hold it in your hand.
