Over on EMTB it seems the go to for reliability is a tighter 10 speed Deore cassette (11-36) rather than the 11 or 12 speed with a dinner plate low gear.Rocky Mountain bikes are top shelf. And the company is not evil like Specialized. An industry friend was enthusiastically showing me these a couple of days ago. They are a great bang for the buck and will out preform $7500 bikes from folks such as Santa Cruz. Really about 100Nm is the upper limit for bike components to hold up anyway such as a performance 11-speed or 12-speed. So 108 is a good upper limit. Because the motor runs the idler you can use any MTB drivetrain. It also helps with the chainline.
