How did this turn out? Did you hit your weight goal? I’d love to see your zombie hawgs pulley. I have a set I’m hoping to use.

I should post the evolution of this build at some point. I hit 13 lbs using 3d printed enclosures and zombie hawgs, but had traction issues when climbing hills with poor road quality. I’ve moved towards Ahmyo Akasha, and reconfigured to FWD to try to improve traction.

I’m also using chain-drive, so it’s less a pulley, more a spacer. If you’re still interested, I can post up some pics.

I’d like to see it. FWD and chain drive on urethane are a bit unique for this space. Sounds cool
