About 80Nm is all a bicycle drivetrain can take without self destruction. What kind of power are you contemplating? I did a Northern California mountain yesterday with 80Nm of torque at max, in addition to me. But only very rarely do I go to maximum power
expenditure because 1) It does not feel 'good' while riding; 2) It uses 10X more battery than level one. My bike had 50-622 tires that are super fast. Yes, it is electric, but does not look it.
