Actually, even though the authors classified as e-bikers those that combine both modes of transportation, the sample they end up with is: - 365 e-bikers (2/3 of them from Antwerp and Zürich, only 20 from Barcelona, only 5 from London, only 18 from Örebro). - 7212 cyclists. - 1758 non-cyclists. There are other things far more eyebrow-raising than the skewed sample. > Categorical travel frequency data was converted into an average number of days per month. > Trip distance was derived by selecting the fastest route returned by the Google Maps API > Distances for multimodal trips were assigned to the main mode using the following hierarchy: public transport, car, e-bike, bicycle, walking > Physical activity from active travel modes was almost the same in e-bikers and cyclists (1735 vs. 1656 MET min/wk., respectively)
