Yeah, I can’t find any info on potting and UL certification, or a “next gen” EM3ev battery.I don't see any discussion of this on their website. Which form factor case and cells did you get?

I think this is pretty big news. GRIN is having a fire sale on all their non-UL packs, and their new UL packs won't be here til this summer. The DIY scene needs UL battery options, but sadly might not be enough:To be totally honest, i'm treated special because i helped them build their company back in 2011. They told me that these new models were just being tested and offered to get me one early. I would expect their listings to be updated in a few weeks.
IGHs have 4% ( Rohloff ) to 15% ( CVT ) more friction than a derailleur setup. Unless we're talking about a 4-5lbs Rohloff or '9x9' then the more gears you get, the weaker they get.
That plus their weight is a thing.
Cassettes max out at 12 gears ( making a strength compromise as a result ) and this drive has higher efficiency so i don't think these extra 2 gears in a Rohloff would make a big difference in bike efficiency since we're constantly taking a penalty. I think it could only make sense on human power TBH. But if you're on human power, you haven't lost your front gears on the crank in the first place, so..
Are they finally making 72v packs again?To be totally honest, i'm treated special because i helped them build their company back in 2011. They told me that these new models were just being tested and offered to get me one early. I would expect their listings to be updated in a few weeks.
I feel like the fun times are over.
11th gear on the Rohloff has no drag, it is straight through. The Rohloff is designed around a large front chainring. That's why it is geared so low. Far lower than a cassette. The idea is you can have a huge chainring for achieving high top speed without sacrificing climbing ability, a tradeoff that every other 1X setup struggles with.
This makes the Rohloff a good match for the Lightest kit, because the Lightest kit needs a big ring to match your cadence to the pinion at higher voltage (48/52).

I'm sorry to hear this but at the same time i feel more grateful to be out of there since '09!
"Electric assisted bicycle" does not include:
(v) any other vehicle with less than four wheels that is designed, manufactured, intended, or advertised by the seller to have any of the following capabilities or features, or that is modifiable or is modified to have any of the following capabilities or features:
(A) has the ability to attain the speed of 20 miles per hour or greater on motor power alone;
(B) is equipped with a continuous rated motor power of 750 watts or greater;
(C) is equipped with foot pegs for the operator at the time of manufacture, or requires installation of a pedal kit to have operable pedals; or
(D) if equipped with multiple operating modes and a throttle, has one or more modes that exceed 20 miles per hour on motor power alone.

None of those laws are enforced here in my area, you would be surprised.
They got copy pasted in the 2010's and haven't changed since.
I see gas bikes all over trails. And generally nobody cares.
I see totally illegal gas mopeds and scooters here and there too, in the car lane even, cops don't care.
You can legally drive an ATV on the street in some counties.
Moab is very different than the Salt Lake area and has special ebike rules because it's a tourist town and bike snob town.
They've had ebike laws on the books for ages but the cops don't even know what an ebike is and they have better fish to fry.
I've passed cops in an adjacent lane doing 35-40 and they're just like whatever
We don't have predatory policing in UT like they do in CA so i'm not concerned. The one exception is the southern border where they will pull you over in a car for anything ( this is a drug smuggling route). Don't worry about me or worry for me.
Nobody cares about your illegal 2 wheeler out here and as long as you don't ride like a jerk with yours, you won't have issues.
You can also have an insanely modified gas or diesel car here. They will only bust you for it when the EPA forces them to do it.
I'm just saying for every place that has ended up with draconian ebike laws, there's another 9 places that don't care about your bicycle at all.
Where did you get that from ? Here in Europe, there is a german study widely spread around. While it's true that under ideal conditions a new clean derailleur will beat any IGH, those conditions are very rarely met, so that in most everyday scenarios, efficiency between a good IGH and a derailleur is almost equal, and if you subtract maintenance over 10 years, a dutch bike with a 3 speed IGH and a completely enclosed chain will smoke away any fancy MTB.I'm just not willing to accept the low efficiency of IGHs in the range i can afford in exchange for durability that's far from proven.
