If you've got a motor in your front hub, the hub would need to be disc-compatible. Then you'd have to replace the fork with a disc-compatible fork. Then you'd have to buy a disc caliper and rotor. The new cabling would be a minor issue compared to the other stuff. Or you could replace the current V-Brake caliper and pads (for a lot less money.)
