You rode the Air S? Cough it up, man. Give us some details on on the ride experience, power delivery, and other intangibles. It was interesting that not a hint of Maxon was at this year's Eurobike, at least anything that hit the news cycle.

Anyone use Pirope? A Velduro Rogue user took the plunge.

We will see how multiple ECVTs motor solutions flesh out (don't forget 2025's E2's ECVT, which BTW has been suspiciously silent after the Gabao/Avinox announcements), but my feeling is that for the whole EMTB system (including the rider), ECVT may be actually more efficient that a typical...

Yes. A devolution/normalization of sorts for all those Rube Goldberg designs out there and suspension IP born from meatbike MTB roots. I'm not saying that this is the preferred solution, but man, when you get familiar with IGH / gearbox / MTU bikes, you begin to really hate that spring...

Here is a ECVT patent diagram that I grabbed from @Ndanger on another thread: The pedal axle needs a way to gear into the planetary cluster either by the sun gear or planetary carrier via a spur gear. After that, the final power gear could be be routed anywhere. In this case extra mechanical...

Look at the mechanical extra design required to get power to the chainring that is axial to the pedal axle. If that was relaxed, the design would even be simpler.

Auto mode is coming for you DD, yeah they're coming for you: Gyroscope and now AI vision using inverse reinforcement learning tech making auto mode all that more predictive. Could even learn your riding habits.

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...

That's a great weight. Tell us about those wheels as they may have made a big difference. Looked up Pirope just now and that was the kind of something I was looking for as cleaner and better looking alternative to Berds. How much did those wheels set you back?

In sethimus snarky prose: "Read my OP again, but this time read it slowly. "

I guessed you missed my point about High-Pivot. Those bikes your rode were low pivot pretty much at BB Level, and as you say nearly zero anti-squat. Besides this kind of pivot location is pretty much impossible with any mid-motor EMTB. I'm referring to high-pivot concentric pivot suspension...

Not if they are high-pivot. Elevated chainstays help (like the Mondraker prototype), but is not required for chain. But if using belt, you would need either elevated chainstay, or Horst Link to separate the chainstay from seat stay during installation. For folks with a belt fetish, VPP and DW...

That they are rare is an indication that either they have undesirable/suboptimal characteristics or that other designs are better or both. Please elaborate so I can address each issue.

That would be exactly what you don't want. The point is to have zero-tensioned slack on the chain/belt to drive power transfer. The top half of the chain loop is completely handled by pedal or motor slack take-up (for what little there is) and as long is there's forward momentum, there is...

Totally agree. I've suggested the term MTU, as in Motor-Transmission Unit as more a general term for combined motor/transmission systems, which would be a superset of MGU, ECVT, and PBW (Pedal-by-Wire). In my mind, MGU should specifically refer to true gearbox systems like Pinion and...

The M1-M2 already is already based on a planetary gear system, though it is fixed gear ratio there for step-down purposes - the ring gear is fixed into the chassis. Not much more is required for ECVT besides connecting the extra motor and unshackling the ring gear to connect to the drive motor.

Firm 203mm mount. No choice to make it shorter.

Yes. Comes with spider and chainring and cranks. Benefits: Aesthetics and weight. And I'm starting with 36T out the gate so changing the chainring anyway.

That wretched thing would never grace my frame. Luckily it came uninstalled.
