Went for it today, only got a bit over mile out before I turned around. I had fun downhill and in flat spots, but even on the highest gear any slight elevation was worse than walking. Bike is an old Walmart bike. I assumed rust was only cosmetic, but I'm probably retarded for that. I can't afford a new one, would replacing the chain or something make it easier? If not I'll just keep going next time, it's still better than sitting around at home.
