I hope this is the right place for this

I just got started cycling (own a TREK WSD 1.2 pilot) and while I was shopping I noticed some really cute TREK kids bikes. My kids received "cheapy" ($20 at Walmart) bikes for Christmas last year, but I have never been happy with them - they feel unstable and hard to control. Anyone have any experience with the higher end kids bikes? I am talking about small ones - 12" and 16" wheels

Thanks!!
