The real problem I see with more powerful eMTBs is TRAIL ACCESS in the long run. 500W is still pretty reasonable, but folks like Luna, HPC, Stealth and Optibike "peddle" 3000W and more! Sure, they generally disclaim these eMotos as "for use on private land only," but we all know folks will ride them wherever...
In my region of the good ol' USofA, the predominant MTB association, New England Mountain Bike Ass'n (NEMBA), outright opposes the use of pedal assist on any and all MTB-designated trails. They specifically call on the Int'l MBA and local land managers to condemn and ban pedelecs, lumping them in with these high-powered eMotos that can reach 50mph, but which cannot easily be differentiated from lower, more reasonably powered ebikes on sight. Unless they're going 50mph, of course, but trying to chase them down would be
cray.
NEMBA's lobbied hard to get my state (MA) to keep calling
all ebikes "motorized vehicles" regardless of Federal guidelines, technically prohibiting me from riding 90% of my area's best singletrack. I ride during "off-peak" hours and have avoided detection for two years now, but fear "No Electric" signage to come. NEMBA says that allowing true pedelec (no throttle) eMTBs on their trails a slippery slope of sorts, one that would create a "management nightmare." It didn't help my cause that someone literally
tore up some "non-motorized" trails near me with a two-wheeled vehicle recently, presumably with an eMoto as it was near a densely populated area and no one heard it happening.
For anyone who cares to read it, here's
NEMBA's "Open Letter..." It's well-written, sensible, and endorses accommodations for "senior citizens or people with disabilities" I'm 54 and endure chronic Lyme Disease symptoms, and I tend to agree with many of their positions. Marketing and promoting high-powered ebikes, especially ones that don't need to be pedaled, should focus on the motocross segment, and true pedelec eMTBs to the 50+ and "differently-abled" MTB crowd.
