IMBA is taking a survey of mountain bikers to “guide our research into the potential social and environmental impacts related to eMTBs.” The survey looks to be pretty quick and easy and you can take it here.
More context from IMBA:
Electric mountain bikes, also called eMTBs, are a rapidly growing component of the bicycle market in the United States and around the globe. As they become more popular, and more capable of taking on singletrack trails, IMBA has responded to calls from our members (as well as our partners in the land managing realm) to study the possible outcomes of the increased use of eMTBs on natural-surface trails.
After you complete the survey, come back and post one word reflecting your overall opinion on eMTBs in the comments below.
