The complexity of the tubing, and it's weight is not a big issue with both the tubing I'm using, and the amount of hp the bike makes. There's about 30feet of it, and it is around .5lb/ft so under 20lbs for the tubing. Why this frame is so overkill stout, is when I was testing suspension settings, I had a cam mounted to a peg pointed at the fork, and it was visibly flexing more than 1.5" in either direction while cornering. And the headshake it gets at 75+ mph is also let happen by the frame being too torsionally flexible. The last frame was overkill for a bike, but too light for what I'm putting it thru. This frame should end up just about right. With that diagonal brace, the battery pack still slides out the top when the seat is removed, so no access problems there. Plus, I'm no lightweight, and neither is my gf, and we ride 2up often, so the overall weight can be around the 550 lb mark with both of us and backpacks.
