Too bad your so far away I have you build him an oversized HD bmx-ish bike. after fixing his main bike 3 times in less than a month (not counting the full tune up the month before) I told him if he wants to ride that hard I'm not fixing another bike for him.That is exactly the type of person I had in mind with this bike, I used 14mm axles and 48 spoke double wall rims, dual ply sidewall tires, all the good stuff, so seeing as I am completely incapable of doing any tricks, it should be complete overkill and last forever!

Think the biggest issue is he likes jumping anything he can (even goes on and off curbs non stop).
