Bought this for my soon to be 8yr old. Also bough the Alpha Three for my soon to be 6yr old. The Prevelo bikes definitely were an investment, but I figured we could get a lot of use out of them as we have a 2yr old as well. After taking all of 15 minutes to assemble both and fine tune them, I rode both around myself. They're solid. I'm really happy with the build quality. The welds are pretty, the components are decent, and they are noticeably lighter than the bikes my kids were riding. In fact they both commented on the weight when they first tried them out, so it is an obvious enough difference for a 6 year old to notice. The kids are digging the gears. The geometry has them leaning forward more than they were on their old bmx style bikes. And hand brakes with no foot brakes is a new concept for them. So there has been a learning curve. Now they're both riding faster and longer. And my older guy who never liked the easy offroad trails by us tried riding them on his new bike and is itching to go again. Everyone is happy!
