sturmey archer

Been looking at the sturmey archer front and rear drum brake hubs, namely the x-rd and the x-fd. Has anyone seen these hubs modified for motorized bicycles. I'd love to get one if someone can steer me in the right direction.

Hello, I'm in the proccess of making a custom motorbicycle, and I plan to use a internally geared hub. I live in Argentina, so I don't have many options. First of all, it HAS to have rollerbrakes or discmount because my rim doesn't allow me to use rimbrakes. I don't know any other brake...
