Just a suggestion, beneficial.
Customer engaged the motor in rear of his Cat-trike
when the axle was out on one end, after rolling ,
displacing wheel, he said, a solo accident.
the torque stripped the dropout as the large axis of the flattened axle
chewed out aluminum..
likely new frame will be required ..

I think he's trying to suggest that using a rear hub motor on a Catrike (since it has aluminum dropouts) is perilous unless you use torque arms to prevent rotation of the motor axle. I have a Catrike with a rear BPM Bafang on it, running up to 1200 watts through it, and I have dual torque arms, one on each side. I also really crank down the axle nuts. I'm not worried.
