"From what I've seen with the 'GeoOrbital' bicycle wheel (https://www.geoo.com), which is very similar in concept, I'd wonder how they are intending to keep debris and brake dust out of the rolling assembly. I believe this is a problem that exists with the Geo Orbital as well as it relies on the smaller 'roller wheels' to keep the tyre/rim in place."

"Hi Theo, thanks for that. I do see the added functionality and it is nice to know this is a consumer product. I have been familiar with the Imagination Playground sets for a while and just noticed they look very similar in material and connection system. "

"Looks a lot like imagination playgound (www.imaginationplayground.com), which to my knowledge has been around for years."
