I'm not sure what 122 ft refers to - maybe cumulative climbs in that 0.95 miles, not counting downhill sections. I would guess the '6:02' refers to how long he has been riding.
If you look at the elevation profile of his route at that point, you will see that the curve veers up sharply, so he is saying that at that spot, the grade is (briefly) 40%+.
Maybe it is an ADA ramp at a curb cut, or something else equally hilly and as long that can be found in N.J. The only hill I ever found in southern N.J. is on the Ben Franklin Bridge from Philadelphia to Camden and it isn't very steep. Don't know of any sustained long steep hill in northern NJ either where anybody would be commuting. A 3 speed should be adequate for any healthy individual to commute anywhere in the state.
