I can vouch for this. I went to two dealers to get my wife's rear tire fixed...it was flat. Both stated they won't work on eBikes. The one was a Trek dealer so he would only work on Trek eBikes. The liability excuses were lame. I finally got the Trek guy to install tube sealent and air up the tire. It works for now. I have since purchased spare tubes but dread the day I need them. I am on a medication and old enough that I bruise or cut so easily my wife freaks out. Changing a tire ( as I experienced on my car) will leave me looking like I ran my hands through a grinder lol
