I actually had one, it fell to it's doom off my arm when i was riding about a week ago, i gotta get another. . . Is there a way to tell how many calories you are burning by heart rate??? It makes sense that there would be.
I was out on a mountain bike for a good 4 hours today and sure enough, i didn't feel ANYWHERE NEAR as exhausted as i do when i'm done bmxing. What I've noticed is while bmxing hard for a good 4 hours as apposed to mountain biking for the same time is that when i get off a mountain bike just my legs are tired maybe my lower back a little, thats about it. When I get off my BMX on the other hand my upper back, shoulders, arms, forearms, legs and even abs all ache much much more. I think it's a combination of the lack of gears and the constant "sprinting" using your arms to pull the handle bars etc. just my thoughts. Feels more like when i used to ride my old fixed gear before it got robbed RIP
