I have a 7-year-old who's been riding a used Islabikes Beinn 20 (small; they also make a 20 large). Great bike, worth looking for, but only available used and hard to find in the US. One of his friends rides a Cannondale Quick 20 which seems comparable and is more likely available at a local bike shop. A lot of the 20"-wheel bikes have shocks; unless you're planning some serious mountain biking, I'd skip those since they add weight and provide little benefit for a kid who doesn't weigh much. I do recommend a bike with gears - 7 speeds has greatly increased how far my son can ride and how steep a hill he's willing to tackle. If you live somewhere flat (we don't) that might be less of an issue.
