Out riding the trails

A bit cold but, very fun to hit the trails first time this spring. My oldest needs a bigger bike and this bike will be perfect for the younger. Appears to be a difficult age to get a good sized mtb. 27.5' is way to big and there are not many 26' out there. I am trying to convince him that he does not need cheap front suspension. A full rigid is lighter and better than cheap hard-tails. But I understand the suspension is cool at this age.
