So the tires I have really suck. They are rated to 80 PSI but probably shouldn't be. One lap around the driveway and the bead blew off the rear tire. It might be the cheapy rims, but the tires go on far too easily. I will have to get a new tire. Hopefully it was just a defective one. The biggest hurdle for the 22" bikes is obviously the extremely limited tire/rim selection.
Other than that, the bike manuals ridiculously well... even while riding with a 20" up front.
I built myself a 22" (wheel) BMX frame so I can get back to having fun at skateparks. Notable features are a straight gauge heat treated downtube and a thicker drive side chainstay (both for added dent resistance)
