ABSTRACT

The purpose of this study was to compare conventional mountain bicycle and electric pedal-assist mountain bicycle (eMTB) use. This was done by investigating two questions: 1) What proportion of health benefits are retained for an experienced mountain biker while using an eMTB when compared to a conventional mountain bike? and 2) What are the perceptions and beliefs of experienced mountain bikers toward eMTBs both before and after riding an eMTB? A convergent mixed-methods data collection approach was used in the study. Participants completed both a pre- and post-ride questionnaire, and data regarding heart rate was collected. Paired t-test statistics were calculated to compare beliefs of conventional mountain bikes and eMTBs, as well as to compare mean heart rate and speed between conventional mountain bike and eMTB use on the study loop. Heart rates from each ride were compared against the resting heart rate. Participants overwhelmingly perceived the potential impact of eMTB use to be positive on both pre- and post-eMTB ride questionnaires. Average heart rate during eMTB use was 93.6% of average heart rate during conventional mountain bike use. Therefore, eMTB use in this study retained a majority of the cardiovascular health benefits and exceeded established biometric thresholds for cardiovascular fitness. Despite the measured benefit, participants’ perceived exertion while riding the eMTB was low.
