The animation you point to rocks back and forward.

You ask for the lever to go up and down by 90 deg, should I I assume you mean from horizontal to vertical? or will 45 deg either way be enough?

See diagram. It is easier to pull the lever up rather then push it up.

The arrangement is the same the distance between the lever centres in the 2 positions will be the same as the diameter of the wheel.
