A few inches short of a 2 foot gear…6.5” to be exact. Talimena Drive in Oklahoma.
The bike with load that requires that less than 2 foot gear. 22/34 low gear

Much closer to a 1 foot gear (a full 10” less than 2 feet) on my bikepacking bike.
That’s a 25% grade which is bad enough…
…if there were air to breathe. Yea, I walked it.
20/36 low gear
