Last night I spoke at a
MARTAB meeting, comprised of Appalachian Mtn Club (hikers), Snowmobile Association of MA, Equestrians, Dog Walkers and other trail interest group members. I made a compelling case that Class 1 eMTBs should be treated as bicycles; many attendees professed unawareness of ebikes on trails.
A couple of sensible arguments came up, primarily that the 20 mph governance might make sense for road use, but not for trails. Bike path and multi-use trail speed limits have always been 15 mph (though I've never seen this posted on any trails), and while many cyclists exceed this without pedal assist, other users oppose ebikes on trails for fear that this will only increase.
Perhaps they wouldn't worry quite so much if we had adopted the EU standard, at least for off-road-intended ebikes. I realize that many EU eMTBers argue that derestriction might not be so prevalent there if the US limit was allowed there, but I tend to agree that 20's too fast for motor propulsion on most multi-use trails.
It may well be that the equal access most EU riders enjoy can be attributed in part to the 15 mph cap.
