Another good reason not allow dongles and s-pedelecs to use any off road public right of way. Also another reason to keep the climbing speed down on a regular e-mtb when passing other riders and walkers etc.
I've been following this topic for a while now, and regular US pedal mtb riders are certainly far more hostile towards e-mtb's than we are over here. I also don't think that throttles and Stealth Bombers/Fighters have done the US cause any favours either.
People whinge and moan about being policed in respect of e-bikes, but without some form of policing, the whole off road scene over here is just going be screwed big time. Sadly at least two dealers over here seem either oblivious to this fact, or simply don't care. I believe that it's the latter.
