Good Kids 20" Mountain Bike

after a bit of research it looks like i'm leaning towards a scott jr for ian's next bike. MTBR contender #2 is the Ibex 320k it seems like every bike at the store is crap. they weigh a ton and the components don't look like they'll last. sure it'll roll... but i want something he can climb some small hills on a little easier. time to "get rad" http://www.scott-sports.com/us_en/product/10066/56126/218027   other options: http://www.islabikes.co.uk/bike_pages/beinn20.html http://fisherbikes.com/bike/model/precaliber-ss http://www.rei.com/product/812664/gt-stomper-20-boys-bike-2011
