New noob (Ebikes) noob here, so be genital. I am wanting to build a front wheel system, but I have a few questions here. I am look to buy this motor. Its the QS 205 35H V. I want to install it on the front forks, with a rack for the batteries above the wheel. What kind of controller should I get with this motor? I really have no idea. A three speed system would be ok, I guess. 72V? What is the difference between brand names? What do you look for in a controller? I really have no idea here. Batteries, How big should 4 or 5 brick be? Will they fit on the rack, mounted in the front? Do I really need 4 bricks, or could something smaller be better? Where would the bricks come from? Any links or recommendations? Also I have heard that vibration is not good for the system. I guess its not good for any system, but the electronics in particular could be reduced, if possible. Would there be a difference in mounting the batteries, and controller in front or on the rear rack?
