1.027 Nm/A? 100A peak phase current for a Cro-motor? I think there are a few people on here that treble or quadruple that...
There is no way a major manufacturer of good quality frames is going to redesign their product range to fit after market hubmotors from small manufacturers in China or Eastern Europe. That's just not realistic.
A key on the shaft might be workable, then people would need a broaching tool to cut a key way into their dropouts. That torque at a 10mm radius might prove too much, though.
Or just have a 20mm shaft with 20mm flats on it and people can bolt clamping torque plates onto their dropouts as before.
