I am thinking of putting a hub motor in my old bike for my son.
Looking at the adverts, they all seem to rely on special nuts in the drop out to stop the axle turning backwards. This does not seem a good idea to me.
Now and again, posters refer to torque arms but I have never seen a picture of one. Further, many hub motors do not seem to have any external structure to which one could be fitted.
Can anyone please clarify?
Mike
