No freestyle, trick or anything just riding. I try not to go over curbs much but do occasionally and when I do it's very slowly, and I haven't wrecked either bike. I'm hoping it was just that those two frames were old lugged frames that were wore out and maybe not too quality either. I don't know what make the first frame was and the second was a motobecane, though from what I understand they were a little better quality when that frame was made then they are now.
