I agree with the above, that what you have is not ideal for a front hub. A mid drive is a better choice and it allows you to use your rear gears. The bafang mid drive is well regarded. If you want more power there is the cyclone 3Kw and Lightning Rods kits (frankly, i don't recommend them. They are great, well regarded units, and the lightning Rods kit is incredibly well built; but they are well over the 750W that is legal in most places).
