Damn, Cheeto... what kind of car is your LBS owner driving with prices like that?!

Ride that bike at whatever your limits are until you break big expensive stuff. After that, get a beefier bike. I always tested how high my bunny hops were when I was younger by stacking 2x4 scraps up and jumping them on flat ground until I knocked over the stack. It's usually not the bike, it's rider. But for some reason I can hop my mom's $250 cruiser bike close to two feet without a whole lot of effort.
