I went for my longest ride on the Big Dummy today. This is maybe the first time I tried to just ride it like a regular bike for a good distance. I ended up with 61 hilly miles. I mostly kept the boost on level 1 and the speeds low. For most of the ride my average speed was holding in the 13s. The first battery held out until 55 miles. After I switched batteries I bumped the boost and the speed up for the last leg home.
