I won a mountain bike 27 inches wheel height... but the problem is the bike is waaaaay to big! And I also never owned a bike and I don't know how to ride one! This is a VERY big problem... I almost broke my arm riding it! ( I was on it and some girl pushed me... I rode it for 15 seconds non-stop when I then realized I didn't know how to stop on it.... I got hit by a car... :-( that hurt sooo much!!!) It is illegal for me to sell the bike (contest rules.... it was a 500 dollar bike) and I have NO money to buy another one. I don't want to wait till I get taller because I probably will never get taller.... HELP.......... (P.S the contest was at my elementary school last year when I was in fifth grade.....I'm in 6th grade now...I'm 11 years old.... I'm 4 feet 5 inches...... I drink a lot of COFFEE.... and I'm a GIRL not BOY
