Evaluating Pedals
Pedals have two sets of ball bearings; there is one set more or less at each "end" of the pedal. These bearings are often not adjustable, and our standards for them aren't nearly as high as on other bearings on the bike. Two two criteria for pedals being ok are that they should have bearings, and the pedal should not be otherwise broken.
Toe clips and straps
Some pedals are made for these and some aren't. For purposes of evaluating the pedal, they don't make any difference - if they are on, but broken, or if one pedal in a pair has a clip and the other doesn't, it makes no difference. They can be removed or replaced, so judge the pedal on its other aspects [[picture of pedal with clip and strap to show what they are]
Bearings
You can check the bearings in the pedal by turning the spindle, and then by trying to wiggle it up and down. If the axle won't turn, the pedal is bad, since it's probably rusted together inside. If it turns ok, but moves up and down a lot when you wiggle the spindle, it may not have bearings. Hold it by the spindle and shake it around. If the sound it makes is more of a "click", it probably has loose bearings. If it really rattles, it is missing the bearings, and you should throw it out.

Broken parts
If any part of the cage (the body of the pedal) is broken, or if parts are missing, the pedal is bad and should be scrapped.
