    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.

    It's probably someone who's first language is not English and running it through a translator program
