GUC. 21 speed dual suspension mountain bike. It comes with an Ulock (and a holder for the lock), light, and drink holder. Brake pads were recently updated. Some parts are a bit rusty, and it works well. 24 inch wheel and 16 inch frame. I am 5'3, and this is a good size. The saddle can be lowered for 2 inches or so, and can be made taller. I have a helmet, but a buckle part is broken. If you'd like to fix it and use it, I'll include it for free.
