A JMIR Formative Research Study
This study aimed to compare conventional mountain bike and eMTB use. This was done by investigating 2 questions: (1) What proportion of exercise response is retained for an experienced mountain biker while using an eMTB when compared with 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?
Mountain biking is an aerobic physical activity that has experienced rapid growth. The emergence of the electric pedal-assist mountain bike (eMTB), while not without its critics, presents the potential for an even larger segment of the population to enjoy the health benefits of mountain biking. Although the research focused on the use of e-bikes generally is growing, there is limited research specifically targeting eMTB use. Research is needed exploring the potential exercise response of riding an eMTB, together with the beliefs and perceptions of mountain bikers who have and have not experienced eMTB riding.
A convergent mixed methods data collection approach was used in the study. Participants completed both a pre- and postride questionnaire, and data regarding heart rate were collected. Heart rates from each ride were compared against each other.
The average heart rate during eMTB use was 94% (31/33) of the average heart rate during conventional mountain bike use. Therefore, eMTB use in this study achieved a majority of the exercise response and exceeded established biometric thresholds for cardiovascular fitness. Paired test statistics were calculated to compare beliefs of conventional mountain bikes and eMTBs and to compare mean heart rate and speed between conventional mountain bike and eMTB use on the study loop. Participants overwhelmingly perceived the potential impact of eMTB use to be positive on both pre- and post-eMTB ride questionnaires.
Conclusions: Despite the measured benefit, participants’ perceived exertion while riding the eMTB was low.

On average, the majority of survey respondents disapprove of e-bikes being allowed on the trail. This remains true across the board for each of the major user groups; however, mountain bike rider respondents are less likely to disapprove of allowing e-bikes on non-motorized trails and equestrian respondents are more likely to disapprove.
In order to better guide research into the range of potential social and environmental impacts and benefits related to the use of eMTBs on natural surface trails, IMBA and the BPSA are interested in what questions land managers have regarding this new use. The survey explicitly targeted land managers’ experiences and concerns regarding eMTB use on natural surface and/or singletrack trails – not paths or bikeways – although some land managers are responsible for both types of trail infrastructure.
The emergence of electric bicycles, commonly known as e-bikes, is a rapidly growing component of the bicycle market in the US. As a transportation option, they represent an opportunity to reduce vehicle use and emissions, as well as the physical barriers to cycling. For use on trails, they present similar opportunities to reduce barriers to cycling but, as a new use, present new challenges for trail management.
