I was able to break it free with a little bit of effort by using a
combination of the rear brake and a 10" curb.  Wedge the bike
perpendicular to the curb, balance bike with left foot, while right is
heavy on the brake.  The front suspension will compress somewhat, but
the nut will break loose.

If you don't have a high curb around, you can try some other stationary
permanently anchored object.

To get it tightened, the back wheel went against the curb.
