IDK about your specific bike, but once the gear reduction ratio is so low
the momentum drops off so quickly when you try to restart on a hill
that it is a challenge to get your other foot on the pedal, particularly
clipping in.
mid 17" low .. less than that or steeper than rideable,
walking keeps my heart rate reasonable.
