I took the day off from work today, but rode into town to run some errands. The foliage is at peak and there was a stiff headwind (10-15 mph). It was my first day riding in wind with the Mango and I was impressed how easily it sliced through the wind. I was able maintain 21 mph on the long stretches without any effort.
It was also my first time going up any really steep hills. You really feel the 70 pounds of this bike on such hills. I dropped into the lowest gear and crawled up the hill out of the downtown at a whopping 5 mph.
