Tye got a new bike for his b-day yesterday,,,just turned 5yrs. Grandpa Henry and myself split the cost, approx. $365 with tax, for this 20" 1x7 from Giant. Sweet little bike for the price and fairly lightweight. It was much easier for him to romp around in the loose stuff with the wider tires...oh, and 6 more gears , than the SS BMX that we bought him last year. He still has some aspiration to race BMX someday, but he really enjoys just riding his bike as well. Just thought I would throw out a recommendation on a good bike for the youngons. Bikeworks has them if you are interested.
