The closest thing we’ve reviewed is the E22. My favorite thing about the 22 is that they use flat-proof tires that ride almost as smoothly as pneumatic tires. Truly the best non-inflatable tires I’ve seen.
I’d like to review the E45, since it seems like a lot of folks are interested in that one. We don’t have it in our plan right now. But I’ll definitely keep it in mind, if we get a chance to do more Ninebot stuff.
Here’s the video on the 22.
