Distinguishing features
I learned how to ride a bike rather late, which is why there's a lack of detail; 820 is my guess on the model. However, this beloved dark red 13" Trek mountain bike, bought used in 2010 at a garage sale in Boulder, had several unique characteristics: Rack with two black expanding baskets (light-colored bungee cord inside one), well-worn seat, kickstand, loose front LED light with three settings, back red light with three settings, no bottle holder, Bontrager wheels.
