I think that’s unfair, in a city for example every equipment made for bikes, like a bridge above a road with lots of traffic or smooth road crossings, make the life of disabled easier too. I’m thinking about wheelchairs, but I guess it’s true even for people who struggle with walking too. And to me, the “fuck cars” Utopia is certainly way more inclusive for the disabled than the current situation.
It depend on your morphology I guess: for me below 15km rides, I can wear jeans and it’s fine, but above that it starts to be painful. When I’m touring I really enjoy having my cycling pant, even a cheap one does the job perfectly for me. But again, I have a quite large distance between my ischium bones, so the same may not apply to everyone.
