Just for the sake of clarity, if you run out of battery does that make these bikes unridable being that they have no physical gears to actually change?
With these E-CVT's kill the rest of the market?
- Thread starter Plummet
- Start date
I read that they will have a limp mode - like they do now as a reserve and for AXS shifting
Who knows, there isn't a production bike yet, but seems likely they will still have a means for changing gear when the motor cuts.
He has a great point, however he seems to be talking about the Rivian bike which is a "dynamo" and not a direct drive, more "Pedal by Wire".
I am not sure why he has the e-cvt type pictured (Gobao / Avinox) which of course are direct drive through complex planetary gearing.
Ride feel starts at 3:30.
Just my opinion, but yes I think these will have an important place in the emerging high powered Class 2+ e-bike segment and I think they make great sense. But I think they will be relegated to that segment of the market ultimately due to lower efficiency, larger batteries & higher weights.
It's going to be fun to watch for sure.
Think of the All Mountain light e-bike market as like the Mazda Miata Manual transmission of the e-bike market. Built more for high engagement, maximum involvement and back to the basics.

Hmm, Alex Bike Tester did say it may be a “door opener to cheaper bikes“ which may reduce the cost of higher-spec bikes too. Nothing wrong with that, right?

I'm glad that he spent time describing the feel of the motor at the pedals; that it felt more response in boost mode implies that there's more software tuning to be done, which is easier to pull off than fundamental mechanical gear changes. Clearly Rob was more blown away than Alex and if I had to place bets, it's no surprise who's opinion I'd trust more.

Kinda.
He describes a series hybrid, but that's not what either of these MGUs are; they're parallel hybrids which are far more efficient. Comparing a Prius (car) with an MGU (bike) is a fools errand, there are too many other factors, but remember that a lot of the power from the rider is directly transmitted through the planetary gear, with only some of it (or none of it if the battery has enough charge) being redirected back to power the ratio/sun motor.
Next up, his efficiency numbers are right for a singlespeed, but that doesn't matter in this case, because the MGU competition is a traditional gearbox, which has far lower efficiency: Which Bicycle Gearbox Has The Highest Drivetrain Efficiency? Rohloff, Pinion, Shimano - CYCLINGABOUT.com
Anyhow, until we actually see these things out in the real world (and until somebody does a methodical efficiency test), we're all just old men yelling at clouds on this topic
It's going to be interesting seeing these things in real life; a bicycle has far different, and in some ways simpler needs than a car. No reverse, no starter, for example.Pour éviter toute confusion, je pense qu’il est important d’utiliser les termes appropriés : MGU pour la boîte de vitesses mécanique (qu’elle soit intégrée au moteur ou non), et ECVT pour la transmission hybride (ensemble d’engrenages planétaires, deux moteurs électriques et moteur à combustion interne ou puissance humaine).

So far it's killed the Pinion MGU, let's see how long the cassette/derailleur manufacturers can stay alive. There will always be a place for derailleurs in the future, but a much smaller one?
What have you heard ?

It seems like the Pinion MGU story is coming to an end. Pinion GmbH has been acquired by Schwarz Group. The MGU e-bike motor will be phased out in favor of retail conveyor systems. This shift is indicated by Avinox MG and Gobao X1P gaining traction.

In answer to the question, I doubt it. Transmission is a very good product IME. The price will also continue to drop over time. I think that CVTs/Virtual gearboxes will struggle to come close in terms of responsiveness. They'll be great for urban bikes etc, but not for mountain bikes IMO.
IMHO good analysis and summary of this invention. From a german website, browser can translate:

Gobao eCVT Motor auf der Eurobike: Greift China jetzt Avinox frontal an? | Scooterhelden
Gobao zeigt mit dem eCVT-Motor auf der Eurobike 2026, warum E-Bikes ohne Schaltwerk plötzlich ernst werden. Jetzt muss Avinox stark liefern.
scooterhelden.de
I agree and good analysis of the industry, including commuters, trekking and cargo
“The next big battle will not only take place at the engine. It takes place with the complete drive system. Whoever best combines the engine, transmission, battery, display, app, charger, safety and service in the future will shape the market. And that's exactly where Gobao and Avinox are now facing each other“
High end bikes are a very small part of the market.
Some might be shocked at how many 26" wheel bikes, front derailleurs, etc. are still sold every year.
That said, this sort of 2 wheeled electrified transportation certainly makes a great deal of sense for much of the planet for commuting, but then why pedal at all for much of those applications?

Humans were asking this very question back in the 60s (I delivered papers with a moped)
