Can you guys help me out? My 8 year old is wanting a new bike for Christmas, and since we have talked about racing someday I am looking at some "real" BMX bikes. My LBS shop has a green Giant Jr 20 (I wish I knew the model, but maybe that will jog someone's memory.) that has aluminum frame (they said), freewheel with rear hand brake, threadless fork. It looks pretty nice and they are selling for $119. Does that sound like a good deal? I am a mountain bike guy, not too sure what to look for in a BMX bike.
