Yes, nearly all decent bikes take 9/16-inch pedals. It might be worth looking at higher-end pedals. A lot of the lower-end ones don't have adequate seals for the bearings on the shaft end. (I'm not familiar with these particular ones). That means that those bearings are likely to go bad much more quickly than a better pedal, unless your riding doesn't involve dirty or wet conditions. On the other hand, these are cheap enough to be disposable. Or you could learn how to replace the bearings and do that occasionally.
