I’ve used one of these that definitely didn’t require a handle, but it wasn’t for working at the same time. If I were in the market, I’d look for manual ones that have that sort of concave dip in the middle.
Thanks for the pointer!
That does look very beautiful!
I am looking to buy a used one, and haven’t seen one of those yet. And, ideally, it should be small or foldable, so I can put it away when using the chair.
We used to have one (now we have a motorized one). No way it could have been used while typing as you have to push against a bar to get it to move underneath your feet, just like traditional treadmills for power generation.
