It all depends on the parents you have, like my wife and I are very supportive of my son to ride his bike, even when he was like 11 years old we would enourage him to join bike races, and when he was 18 years old I, bought him a nice Pinarello Bike, with Shimano ultegra Groupo, see, if your parent are into biking your parent would probably encourage you to ride a bike, and might even buy you a high -end Bike....try not to get mad at your mom, you will only have one mom and that's it for you, just one :thumbup: :thumbup:and to answer your'e question, "No your not justified in getting mad at your mom"
