This summer one group of these, in your opinion, so honorable gentlemen ran a female novice rider from my group off the trail because she could not let them pass quickly enough in a tight single track. Tire buzzing on the rear tire of the novice rider was only possible for those fucks because they had electro power.An EMTB rides absolutely nothing like a (lite) moto at all. Those "fat" riders you dislike's weight, lifestyle and fitness are not actually a problem at all.
Call me narrow minded, I am happy to be that if this is OK behaviour in your opinion.
