like most of the others have said, it's your riding style, not bottom bracket height, that will most greatly influence whether your smack your pedals on the ground. due to my own idiocy of not compensating for different geometries, i've managed to pedal strike on everything from road bikes to a hybrid. the hybrid was awesome for "omg, i think i'm going to kill myself" style strikes; i managed to do it at least once a week. just learn what your lean in limits are on the bike, and adjust speed and pedaling accordingly.
