Does the May 2026 Bosch Update Have any Impact on the SX Motor and if so, What Is It?

As usual, Bosch's online information about this is buried in the terrible UI of their website, about six clicks deep, following multiple asterisks and footnotes, and AI is predictably stupid at ferreting out this particular data point.

Here's what I think: While the CX and other models get a big boost in power, the only difference for the SX is that there *might* be a longer duration for 'boost,' whatever that is. (The SX's power increased to 60nm from 55nm in 2025, and I doubt it could go any or much higher.)

However, it's also possible that the update allows-- or forces-- faster charging, which I definitely do not want. I'm not that impatient, and I have a longer attention span! What's more, faster charging will, long term, have a negative impact on battery life. If anything, I'd want SLOWER charging.

Is there anything else? Has anyone been able to figure this out? I figure @stompandgo probably is the only one who knows!

Thank God the UI for the Flow app itself is not as irritating as Bosch's website. I'm a recovering tech writer, and this drives me crazy, tech writing seems to be a lost skill, though it would be so easy to fix! All Bosch would have to do is list every motor (with corresponding model number) and then list every single change that applies to that motor. But the documentation is written like code, they're trying to 'call' the same words and phrases and apply them to different motors as if they were subroutines.

Opacity seems to be a virtue in every application that isn't shareware or low-one-time-cost. The reason I usually only use shareware or non-subscription applications isn't because I'm cheap-- or that's not the main reason. It's because non-subscription software is almost always more efficient. To me, Open Office blows the doors off Word for work most humans actually are likely to do. Reaper smokes ProTools... okay, I'm getting annoying! I'll stop now, I swear!

The thing about Bosch that many forget is, that whatever configuration Bosch offers is controlled by the bike manufacturer, not Bosch. Bosch offers it to the manufacturer, but the manufacturer has to adopt it. Any upgrades, and when they are offered, are controlled by the manufacturer. I don't know about Canyon, because they are DTC. We only work on them when they are brought to us by the rider. We can check them with the Bosch diagnostic to see if anything is available. I suggest that you call Canyon support and see if and when any upgrade would be available for you.

Sure, I can do that, but I'm first trying to determine whether the update even impacts the SX motor at all.

The app is encouraging me to update, I just don't know what the update does generally.

Once I found that out, I could then determine whether Canyon was offering it for their bikes. The last SX update seemed to work really well, and I was able to research its capabilities much more easily.
