I would put n a vote for Cleary Bikes as well. Their 20" bike weighs in at about 19 lbs, and is built very well. $335. that being said, I would not probably buy less than a 20" bike (kids grow too fast) unless you have multiple kids that could get them handed down. My son had a big box 30# rolling crap ball, and rides much better on the singlespeed Cleary. Kids don't need gears, shocks or other doodads. Kids need lightness and quality.
