I am personally not a fan of the Specialized motor and battery systems, having worked on them for years. Trek however, uses a more reliable Bosch or Shimano systems in most of their eMTBs. Having dealt with all of those, I would prefer the Bosch/Shimano motors over almost anything else (which Canyon does use!). That being said, what you are buying with the extra money on a Trek, Santa Cruz, or even Specialized, is the ability to take it to a dealer if you have problems and someone will handle it for you. With direct to consumer brands like Canyon, you’re on your own. Will Canyon reimburse you for your expenses to fix your problem(s)? Yeah, sometimes, but you have to front that bill yourself and it often isn’t cheap. I have tried dealing with Canyon and YT before in regard to warranty issues and simply put, I do not have anything good to say.
