Your mom is being wayyy over protective. My mom is the same way with my younger brother. I'm 36 now, but have always done my own thing and mom was fine with all my crazy dumbass **** over the years. My brother is 33, and she still admonishes him about how dangerous cycling is. To the point where he hardly even rides his Trek. He lives with his wife in their own house for pete's sake, LOL. I ride downtown Toronto all the time, never a peep from mom. I think the advice in this thread is pretty good for you!
