Attaches to the spokes ? Okay so I have the BBR Racing stage 4 kit. I've been so much wanting one for 3years quite so time to be looking at a motor doing research and still not understanding once it's on front of me. I'd be accomplishing you finally knowing what type of forks I'll have to your comment before. Also is there any other kind I thought that was the only kind motor underneath sprocket connected inside the hub well outside of the hub but on the inside of the sprockets if there's any other kind that I might be interested in care to share an image of it.
