New mountain bike

Im a 15 year old boy from the Czech republic completely obsessed with downhill mountain biking, i broke my last bike and my parents dont want to give me anymore money cause they think that ill break it again, ive tried multiple ways of making money but none of them have really worked since being a 15 year old and trying to make money is very hard so this is my last hope, if anyone is actually kind hearted enough to donate even a penny you'll be greatly appreaciated and unforgoten, any leftover money will go to the rainforest alliance charity.
