So some have the problem, and some don't. Hmm.

Had an Origin8 crawler with the nuvinci hub. Hub worked well, liked the step less shifting. Nice technology. It was reliable. Had the smallest cog, gearing was still a little steep for serious mudding. Generally liked the bike/hub combination- however it was such a heavy beast, traded it for another passion.

I've been extremely satisfied with my N360 (except the shifter*). I have about 5000 miles on it, including a 3200 mile self-supported tour. The rest of the miles have been commuting and utility use.
If I was having the problems the OP has, I would first verify that the shifter interface was installed properly, allowing the lowest gear ratio to be accessible. Since the hub is relatively rare, most mechanics aren't familiar with them, and a mistake could easily be made in this subtle aspect of the installation. Due to the nature of the CVT, the mistake would be hard to detect while riding. The hub would seem to be working properly.
* At around 1500 miles, I replaced the NuVinci shifter with a Rohloff shifter, and have been very pleased with it.

Ah, this topic again... 
Yea, the shifter needs to be adjusted properly, at both ends, and check for kinks in the cable that may be hampering shift range.
In tyler state park, here in newtown, there is a 26 percent grade down to the canoe rental & cookout area. On my old 4 speed nexus hub, i had to walk to near the top if the hill to keep going...... With the N360 i can ride all the way up without struggling. This isn't some huge time gap of fitness either, just 2 weeks before my old bike had its final crash, i rode in the park & up that hill and ended up having to walk up. My new bike also has a dyno front hub that is a bit draggy (all the time), and is about 10 lbs heavier, so obviously the N360 is a marked improvement.
Are you able to get the shift indicator (pictured below) from near flat to near vertical?
Will toss in photos of my own tomorrow so you have a A and B comparison.
Sounds like you may have either the shifter put on incorrectly, or the axle isnt even in the dropouts or some odd kinda thing. It shoould not feel like tar, but its not going to feel like a chainring/casette either.

Bikes: This list got too long: several ‘bents, an urban utility e-bike, and a dahon D7 that my daughter has absconded with.
Copied from my post in another thread:
Even though I like the N360 on my Novara Gotham, I am thinking that I may start saving for a speedhub.
First off, I have a NuVinci 360 on my commuter bike and with certain reservations I recommend it strongly. However, I will share this chart for those interested:
From and article translated here.
I think that the NuVinci did poorly because it really dos not fit the parameters of the test as well as the other IGH systems. Also note, there is no comparison of conventional derailleur based systems. Also, it should be noted that the graph starts at over 70% efficiency.
