This is what I wrote, but since it is a closed group, I don't want to post the results. You can join the SE Mass NEMBA group and see them if you want.
Class-1 eMTB are accepted in Europe as part of the sport of Mountain Biking. These are bikes limited to 20 mph and one *must* pedal. They have not really caught on in the US so far, though a lot seems to be in flux. For example, the Tahoe area of CA did a multi-year study and decided to allow them on normal natural bike trails. They will almost certainly spread to ski resorts in VT and NH soon, and then trickle down to other trail systems.
Questionnaires done in 2010 and 2015 showed that most Mountain Bikers in our area were not ready to accept them. More nationally, after seeing views start to change, the IMBA changed to position in 2017 to support them on natural trails alongside manual bikes. They updated this statement again in 2019 to reaffirm this support. PeopleForBikes, and MassBike, also supports Class-1 eMTB.
NEMBA leadership has been against Class-1 eMTB, but didn't poll the public or members, as far as I know. They wrote documents and sent out letters asking that eMTB not be allowed. The newly-proposed MA DCR regs now have language to formally ban Class-1 eMTB from our single-track, and these regs, if approved, could easily be in place for decades upon decades as this new technology continues to evolve - leaving us out of the fun that will be happening everywhere else.
I support e-MTB (Class-1 only) on natural single track, but I have no idea how most people feel - so I am doing a casual non-scientific feeler poll to get more of a sense for it. Maybe few other people think they will ever want one in the future?
Yes, Class-1 (20mph limit) low-power pedal-only eMTB should be allowed on bike trails:
No, even low-power eMTB should be banned from bike trails.
