Well let's see, where to start. I bought a second hand controller from Endless Sphere just to get things rolling. Spent all afternoon redoing wiring to fit the new 300A Kelly controller. Got it to work. Secured battery with fiber tape and rode around driveway. Went awesome. Thing is just nutty with power. Which upon retrospect should have been clue number 1... So I went out on main rode and ripped up sidewalk. Thing wheelies going 20mph, and I'm 240#. So I start really getting after it and hauling down the bike path. For reference I was wearing shorts & flip flops. Then I turn around and head back. All was going great until the fucking rear wheel literally flew past me. Like really fast. The back of the bike dropped down, out came the feet and I skidded across 2 driveways and came to a rest. The rear wheel kept going and crashed into my neighbors house. Who promptly came out to inspect the projectile that plowed through their bushes and hit the house. I was just dumbstruck. It would have been the best youtube video ever. I don't know how I kept it on 1 wheel. Anyways, the rear dropouts got seriously torqued and I think are pretty effed. Will require swingarm removal and bring it into machine shop. Quite a bit of damage. I think the torque just twisted it right out of there and snapped the 2 dropout retainer bolts. Will need to rethink this.
