Hi, I was just wondering if anybody else here rides mountain bikes?. I used to ride BMX bikes all the way up till I got into my 30s and then stopped. I decided to give mountain biking a try last year because I wanted the exercise but needed something that was lower impact on my knees then running. Needless to say I fell in love with it and I'm planning on riding a lot this year. I was just wondering if there was anybody else on here that rode.
