Moonwalkers use an automotive-grade sealing method to ensure that they can withstand rain and smaller puddles. We recommend that you avoid puddles and only store them indoors when not in use.
We are based in Pittsburgh, so we have a ton of crumbling rust-belt-style sidewalks. We didn't want to make a product that couldn't handle our current city, so we engineered our 8-wheel patented drivetrain, consisting of overlapping wheels to simulate much larger diameter wheels to climb over uneven terrain and gravel.
