Klvied Adjustable Height Standing Desk with Cup Holder, Portable and Easy to Move, Ideal for Home or Office, Black

What is the maximum height of the keyboard section while tilted?

I am 6’1 and recently had spine surgery. Will this raise to a height that keeps me from having to bend forward?

What is the length between the two bottom bars? Specifically inside to inside, not from wheel to wheel. I have a 19 inch wide treadmill.

Is the piece that holds the keyboard from falling detachable? If I have it flat, I don’t want that piece bothering my wrists.
