My son is 8 and on the small side. He is an avid cyclist and can comfortably do 20 miles with me at a good 12mph pace (give or take) on his heavy, old one-speed Schwinn. I really want to get him on something geared and more light weight so he can go even further - he desperately wants to! I'd love to find a kids road bike in my budget but also think it would be best to get him in gears on a familiar mtb style first before moving to a road bike. And there's the budget issue....I'd like to not spend over $200 - $250 new, and will always look for any recommended bikes used first.
