I ride a Supercycle SC1800 from Canadian Tire, a $100 18 speed MTB. It needed adjustments after I brought it home, but I have been riding my 3 mile round trip commute with it for six weeks, and use it for grocery getting. It gets ridden on rough pavement and a short, rocky stretch on the way home. I'm hoping that if nothing has fallen off in this shakedown, it might hold together till next year. The plan is to use my GT as a commuter if I still have it, and buy a new single speed for pleasure riding.
