Has anyone else seen this!? Thoughts and opinions?

I came across it the other day and am totally obsessed. I have limited range of motion in my back and hips so riding a standard bike has been off the table for the last few years (I used to ride all the time). The only exercise I get now is walking. I'm thinking this treadmill bike could be the answer for a lot of folks with AS. Genius invention. I am seriously considering ordering one up.
