Enviolo Automatiq auto transmission for e-bikes/e-cargobikes
mzjo:
While idly browsing the web, looking at cargobikes when I should have been more gainfully employed wiring light and power for my daughter's "workshop", I came across this https://www.veloelectrique24.fr/fr/envolio-automatiq fitted to this https://www.yokler.com/accueil-fr/en/triporteur-cargo-espaces-verts-et-collecte-de-dechets/
Appreciations and criticisms of the vehicle apart (I was curious but it would fall far short of our requirements in capacity, autonomy and speed) I was curius about the transmission. Impossible to believe that it has flown under the YACF radar but a search has failed to find it. The company site isn't that informative (I can't tell if it's their box or an add-on to a Shimano Nexus and if it is really continuous variation, like a Nu-Vinci or just prestaged changes to maintain a regular cadence).
Anyone know anything out there? Just curious :) :)

ICE are fitting them, so they must be vaguely decent. It's definitely a CVT.

It's not like a Nu-Vinci, it is a Nu-Vinci.
Repackaged and rebranded for E-bikes, the electronic shifting, manual and auto, is new, otherwise it's basically the original hub. The criticism of the original, was the narrow gear range and the loss of efficiency, both of which are less relevant once you add a motor. Indeed, the ability to keep the motor spinning at optimum efficiency may well outweigh the inefficiencies of the hub. I don't think there was ever any criticism of the hubs doing as claimed or a reason they'd be less reliable than the alternatives.
I had a test ride on a Riese & Muller light (haha) cargo bike with one fitted, I fond it a bit odd, it may be that it would just take longer to get used to it. Either way the bike was out of my range, but that such manufacturers (As with ICE above) consider them worthwhile shows they probably are.

The main issue with NuVinci hubs seems to be that bike shops don't know how to correctly adjust them, which is a significant problem for a large portion of the target market.

I imagine riding a bike with a CV transmission is odd. Just like driving a Daf or Volvo automatic car, you accelerate with the box not the motor - except that it's you that has to try to accelerate against a box that will oppose your acceleration by changing up. It might be easier with a motor but I bet the electronic control is a game-changer.
Interesting that Tern are fitting them to a folding e-cargobike - I wouldn't have thought that the Tern really needed that level of assistance.
