Enviolo NuVinci CVP Hub Overview


Staff member
While visiting Propel Bikes, in Long Beach, California, for some Riese & Müller reviews, I had an opportunity to dig into the Rohloff E-14 as well as the updated Enviolo N380SE. These two hub drivetrains allow for shifting at standstill, they tend to be more durable than a traditional cassette + derailleur, and they are starting to popup on more ebikes and bike share programs. This is especially true for the Enviolo N330 model, which is also appearing on the Moustache Lundi value model. The following video and specs come from my own research, input from Chris Nolte, and some conversations with Avelino Rivera of Fallbrook Technologies (Enviolo/NuVinci) who is a Business Development Lead for North America and Bikeshare Globally.

The big takeaways for me are that this is a stepless system that can be adjusted while pedaling or at standstill. The NuVinci optimized products are labeled as Continuously Variable Planetary hub systems (CVP) but also sometimes referred to as Continuously Variable Transmission. It's the same sort of technology used on the Toyota Prius, to optimize motor RPM and reduce energy loss and transmission wear compared to set gears. Here are a few more interesting takeaways from the research we did:
  • The Enviolo name is a modification of the root acronym NVO, which stands for "NuVinci Optimized" and thus, almost makes the name recursive. Fallbrook Technologies is the parent company here, and as they applied the NuVinci technologies to more applications and really started focusing on bicycles and electric bikes, they began calling it NuVinci Cycling but then moved to a new more unique name to apply specifically to the cycling space, and that is how we got Enviolo.
  • As a planetary system, the insides of an Enviolo hub include spheres that orbit the center axle. The system is not being produced in 135mm hub spacing with a 10mm threaded axle for the standard N330, N360, and N380 products as well as 135mm, 142mm, and 148mm hub spacing with a 10mm threaded axle for the N380SE (Special Edition) to be used with wider dropouts and Boost hub spacing.
  • The SE model offers wider hub spacing options as well as a higher torque rating of 100 newton meters continuously and up to 120nm peak. It's a product that targets sportive and cargo bike applications and is well-suited to the Bosch Performance Line CX motor, which produces up to 75 newton meters of torque.
  • Enviolo has moved towards an all-black look with their hub and shifting mechanism, the older NuVinci shifter was called the Nfinity C8 and had a silver casing.
  • The weight of traditional cassette + derailleur is usually somewhere between 1lb-2lbs while the Rohloff Speedhub is roughly 4lbs (1,820 grams) and the Enviolo N380 is roughly 5.5lbs (2,400 grams). Part of what contributes to this weight is a special traction fluid inside, made by Valvoline.
  • Sometimes, the Enviolo NuVinci system can feel sluggish or soft when pedaling and I've been told that there is a break-in period of ~500 miles where it may not be operating at optimal efficiency... but the addition of traction fluid and the orb pivot system vs. gears just isn't as crisp and quick as a derailleur + cassette or most planetary geared hubs.
  • Maintenance on the Enviolo NuVinci optimized hubs for bikes appears to be very low. There is no specified maintenance interval for this product, vs. the Rohloff Speedhub which recommends changing the oil every year or so depending on use. There is no bleed valve on a NuVinci hub for owner servicing. The most vulnerable and wearable parts on the system appear to be the shifting mechanism and two cables that are utilized in changing gear ratios. The Harmony and HSYNC electronically shifted NuVinci products probably require even less maintenance, aside from battery care, because they use much shorter shifter cables and only a single electronic wire.
  • Part of what makes these systems so tough, especially the mechanically shifted Enviolo, is that there's no derailleur hanging down off of the side. If the frame gets banged into a rack or pole, or maybe the bike tips over, the drivetrain won't get damaged or go out of tune as easily.
  • The Enviolo product comes in a mechanical version (with two cables/wires that you physically move when you twist the shifter), a Harmony version (which relies on an independent power source and proprietary shifter), and an HSYNC version (which integrates with electric bike systems from Panasonic or Bosch, to utilize their battery, display, and button pad).
  • With Bosch implementations of HSYNC, an additional level of shifting optimization is introduced through eShift. In short, the Bosch motor controller listens for shifting signals that are triggered whenever you change gears, and the motor backs off to allow for smoother gear ratio changes.
  • Chris talked about a hardware project between Continental and NuVinci which would integrate the continuously variable transmission into a mid-drive motor. I haven't seen or tried this system, but it sounds neat.
  • Right now, The Enviolo product is focused on five categories of bikes including: City, Trekking, Bike Share & Business to Business, Cargo, and Sportive
  • Drive systems that have been using the HSYNC product include Bosch and Panasonic. Companies that have been selling in on their ebikes include Flyer, Tempo, Piaggio, and Butchers & Bicycles. I was told that HSYNC uses the CAN bus protocol to interact with drive systems and may feature heart rate optimized shifting in some situations in the future. I personally am wondering if we will see this from Bosch with their new Bluetooth compatible Kiox display panel.
  • Some companies, like Riese & Müller have opted for the mechanical shifting system only, because it performs in a sporty way that accommodates advanced riders. It may also save weight and cost.
  • It sounds like the Enviolo mechanical shifting systems may be available aftermarket, through select dealers. The cost for hardware is likely in the $500 range but service and installation could get expensive because the hub has to be spoked into a wheel to fit the size of your original bicycle. They use J&B imports as a distributor in North America.
  • For those with wider axles, it looks like the Enviolo hub is compatible with dropout kits. these may allow it to work with a 12mm thru-axle setup but it may not work in the case of thru-axles because the original 10mm axle is fixed to the hub.
  • One example of a bike share program that is using Enviolo NuVinci is Motivate, which was recently purchased by Lyft. It sounds like they paid $250M to become America's largest bikeshare company. They will reportedly be using the Enviolo N330, more affordable and limited range CVT system. In related news, Uber reportedly spent $200 million on a bike share program called Jump.
  • Other companies that use the Enviolo NuVinci CVP systems include Organic Transit, EVELO, Riese & Müller, Piaggio, Velec, eProdigy, Moustache, Corratec, Butchers & Bicycles, CUBE, Grace, Urban Arrow, Bodhi (no longer in business), Merida, Centurion, Pegasus, Hercules, Zemo, Sparta, Sinus, Felt, Trek, and KTM.
After posting this guide, reps from the company told me that "enviolo is always with a lower case letter and we currently have enviolo Manual products (known as Nfinity), enviolo Automatic products (former Harmony) and enviolo Automatic+ (former HSYNC)". I welcome corrections, more details, and other examples of companies using Enviolo and NuVinci technology below. I'll keep calling these out in my reviews and am excited to see how CVP and CVT technology is used in the electric bike space.

Do you know if R&M will get the E-shift version of the Enviolo (Harmony)?
So far it does not appear as an option on their site
I think the biggest question to answer is efficiency loss. IIRC from previous performance comparisons that people did, NuVinci did significantly worse compared to Rohloff. The numbers that come to mind are 5% loss for Rohloff vs about 9-10% loss for NuVinci. I wonder if this number has changed much. Obviously for ebikes it's not such a critical number, but it's still important.

Also, I'd be curious to know what happened to the N380X model that NuVinci was working on. From what I remember, they were supposed to support thru axle dropouts. Rohloff's offering in this area is... difficult to work with, so I was hoping there would be alternatives.
After speaking with R&M I can anser my own question, they said they stopped supporting Harmony (NuVinci / Enviolo Eshift)
To Dmitri, the N380X is Enviolo Sportive groupset
Thanks. It talks of 'thru axle adapters', I'm guessing it's the same story as Rohloff, basically using screws to hold the hub in place. I would much rather prefer a proper thru axle solution. I prepaid for a Kindernay hub but it still doesn't seem to be out yet.
Fallbrook never really pushed the Nuvinci, it always felt like a side afterthought to their main business.
Now that they have filed for bankruptcy, and that NuVinci has been given its own company, we can only hope they will be more focused and proactive, but I have not seen that happening yet...
I have two nuvinci problems and I am wondering if anyone has some ideas.

1. Nuvinci n380 with gates. I get full range on the hub, but the info graphic goes from steep hill to moderate hill only. It doesnt go flat. No biggie really, just curious.

2. Nuvinci n360 with gates on pegasus premio nu. The grip shifter has significantly more resistance than my n380. It's harder to turn and dial in the perfect cadence. Cable tension is set right with full range of shifting.

Any ideas?
Sounds like misadjusted and or incorrect tension in cables.
You may want to have the cables reset by a NuVinci installer, or go through the installation yourself to make sure the cables are properly set and tensioned
@Ddewsbury, @scrambler is correct, the Nuvinci system isn’t set up correctly. If you go to their website (Enviolo) and download the install manual you will see a step by step setup. Take your time to follow the instructions and once complete the system will work fine.
My n360 shifter turns easily on level ground and when standing still, but when going uphill it is extremely difficult to downshift. The guys at Evelo told me years ago that this is normal. I have to downshift before the incline. My next bike will have the Harmony transmission.
Are you trying to shift under load?
Because even with the NuVinci, you need to ease up on the pedals before shifting.
If abnormally hard to shift when not applying pressure on the pedals, then adjusting the cables should help too.
Yes, definitely under load while going uphill. Yet on level ground and under load it shifts easily. The thing is, if you stop pedaling uphill , even briefly, the heavy bike slows considerably.
Pedaling on flat generate a lot less torque than on a hill.
That said, it is always worth readjusting the cable as per the installation manual, to be sure your get optimal behavior.
How reliable is the Enviolo with a mid-drive motor on a cargo bike, ie. a much heavier bike than a regular e-bike?

It depends on if the owner follows the servicing schedule in the Enviolo Technical Manual. My Enviolo Heavy Duty Cargo hub has a solid axle, fastened with acorn nuts and it’s behaved well over the first 5 months of riding. I had the wheels off in March to swap out the studded tires for regular touring tires, hand tightened the acorn nuts and they’re still tight two months later. A friend of mine has a 2-year old Tern GSD S00 model with the Enviolo HD Sportive hub affixed with a long M6 bolt on each axle end. The Enviolo manual says to check the torque monthly, but this week she complained of rubbing against the wheel and on inspection the left side M6 bolt and spacer was missing and the wheel was held on by only the right side bolt. Very dangerous. My friend had the bike serviced once since purchase, but presumably had not been checking the torque on those M6 bolts as per the manual and vibration caused the problem. The issue is not with the hub which works fine, but with the mounting hardware of the Sportive model on this cargo bike.

Thanks. I was more concerned about the internals, since like all gear hubs save the Shimano Nexus 5, the Enviolo predates mid-drive motors, and some users can be a bit rough.
