So I took my 12yo out riding last week, and noticed he was lagging behind, long story short when he caught up it looked like a bear on a tricycle. Time for a new bike, really trying to keep the cost decent as I'm sure he'll outgrow this one in 1-3 years, but he's shown interest in riding for his middle school team so I don't want som 30+ lb beast with heavy parts. The best I've found so far is the Polygon Xtrada 7:

Everything else I've found in the sub $1000 arena seems to be really lacking. If any one has suggestions I'm all ears.
I should also add he's 5'6" and 120lbs, so we're squarely in adult sized bn
