You guys are sick. Please tell me you are able to achieve 30mph+ on a GEARED BIKE! Please!!! I haven't ridden a bicycle to work since September.
When I started riding a few miles to high school, my normal flat-ground speed was about 12 mph.
Now my normal flat-ground speed is somewhere around 16 mph (no cyclocomputer, I'm guessing based on time and distance) but I think on downhills I occasionally go up to 28 or so. No long steep hills here, but I pedal hard on downhills sometimes.
