Bicycle rolling resistance measurements and video recordings under winter conditions in Trondheim 2019

Hypothesis: Cycling comfort under winter conditions correlates with bicycle rolling resistance; bicycle rolling resistance depends on performed winter maintenance; to maintain or increase the share of people bicycling in the winter, the rolling resistance level must be kept below a critical limit. The data was collected using an instrumented bicycle with sensors measuring speed, road slope, pedaling power and air speed. Dataset describing cycleway conditions and propulsive/resistive forces under winter cycling during the winter of 2019 in Trondheim, Norway. The dataset includes raw data from rolling resistance measurements, documented road conditions and video recording of the test sessions. The road condition data contains details about the snow depth and type, and objective perceived cycling comfort in addition to some location identifying information. The most important data in the propulsive/resistive forces files are speed, pedaling power, air speed, air density and road slope. The air drag coefficient was determined in an isolated wind tunnel test, as well as in an outdoor field test
