I'll second that.....but for the Helios.
Having said that, I realize the virus has really disrupted production and deadlines. I ordered a set of carbon wheels (for my Cannondale Lefty 3) from Yoeleo, on October 13th, and I'm still waiting for them to be built and shipped.
Any of these systems won’t work in deep powder. Hard packed snow can be found in ski slopes which won’t allow you to drive these things there. Atleast not during opening hours.
Only place I can imagine this thing would work is spring-hardened snow. On that type of snow you can walk on, or even drive with an ordinary mtb with studded tires.
My country has plenty of snow. Maybe 100-130 days a year. Yet I can’t imagine more than 10 days a year I could benefit using this system on my fatbike. An interesting concept and it’s nice ppl innovate new stuff but be honest how much could you benefit...
