BMX BIKES

well awhile ago when i was about 9 years old I rode bmx bikes. Not your ordinary riding a bicycle, but jumping 10 foot dirt jumps and racing and stuff like that. well one of my good friends anthony gave me advice on how to ride the track quicker, and it turned out to be a total fail. he told me to pedal as quick as i could and pull up off the lip of the jump. At first, i thought what a piece of cake? then i attempted and not only did the bike fly 15 feet away from me, but i swear i had road rash on my legs and butt cheeks for a month lolol..
