Mostly just based on my own aesthetic preferences -- I wanted it to look light/simple by leaving that center portion open. The battery only ended up weight ~2.5kg and the controller was super light, but for a larger electric motorcycle type battery, I would definitely want to shift it down.

Hey thanks -- I got it up to 36mph, but got spooked and slowed down. The no load rpm gets me to 42, so I assume somewhere around 39/40. Range wise I'm getting 23-27 miles per charge at top speed 25 (legal max in my state), and that's in hilly Pittsburgh, PA.

Hey, I added a little wiring diagram that should cover all of the common connections you'll run into. If you're trying to salvage lighting components from the existing system, you'll probably have quite a bit of wire following to do to determine where the connections are made (for probably similarly colored wires).Generally if you buy a hub motor, you can purchase the disc brake from them as well (that will fit and bolt onto the hub), but the brake caliper mounting could require a custom plate depending on the frame. You might be able to get away with a "disc brake bracket" that will screw onto your frame, but if you run into trouble feel free to DM me.
