If I had an ISIS left side power meter, I'd test the accuracy of the motor human power input.

Finally got a chance to ride the BMC Road machine Amp X with TQ50 drive (thanks to all those on this forum that helped along the way). This is my first ebike and was not sure what to expect. 42 mile/2600ft elevation test ride today confirmed what many of you said. The motor is silent, the assist feels natural and unobtrusive, (so much so I had to look at the power meter to confirm the motor was actually adding power). Just felt like a normal bike, but I felt 10 years younger! I was riding with a younger/faster rider and the assist leveled the playing field (took them awhile to figure out I was on an ebike). Never needed more than ECO assist on climbs and on the flats rode with no assist no problem. I did not notice the extra weight other than lifting it onto the bike rack.
I think I am hooked, and suspect there will be less days on my analog bike from here on out.

Congrats — gorgeous bike! Sounds like BMC's evil scheme is working.

Love the TQ display showing instantaneous power (W) delivered by rider and motor. Is there any way to get accumulated power (energy, Whr) over the course of a ride either from the TQ system (app or service dongle) or by using a Garmin that accumulates the instantaneous power to provide energy data for the ride?

The closest I’ve found for energy use during a ride is with my garmin: open the ride in garmin connect after it’s logged, scroll down and select ebike performance. It shows you the % of battery used on the ride and a graph of time in assist levels.

I use a Garmin Edge 840, but wait until the new TQ app comes out. It may have that kind of functionality, beyond the distance/speed logging that it does today. The current TQ app is way behind other similar apps.

Does any bike display, GPS computer, or cycling app show energy expended in real time during a ride? The Specialized app shows the total expenditure, but only after the ride's finished.

doubt it
most show wh of battery, so you just look at the beginning and do the math?
i take a screen shot of the battery screen before and after each ride, just to have my own record of wh used when looking at rides in strava and so on

Sorry, meant rider energy expended in real time. The software would have to integrate rider power over moving time to the present moment.

ah ! rider energy!
the one i use will show calories, workout load, intensity, etc. calories is basically total energy, easily converted to wH but it uses the kCal unit.
it also shows average watts and elapsed time, which is even easier math and doesn’t rely on the “efficiency” factor.
a cool metric would be rider total energy : motor total energy in pie or bar form. the mahle app shows that in real time but not in sum.

Yes, but the question is, can you see the energy you've already put out during a ride?

Not in real time. My take is that this would be unreliable unless it was heavily weighted. For example, the display may say that you've burned 200 kcal so far, and then you eat a gel. How does it know that?

I don't. I did not see any announcement about the Service Management upgrade until I plugged the dongle into my bike.
Like I said, I use a Garmin for this data, but so many competing drive unit platforms have the data you are looking for via the app. You should not have to purchase a bike computer to get it.

You might be surprised to hear it but the only app that can do it is BLEvo. Unfortunately, BLEvo does not work with Mastermind e-bikes (shame on Specialized!)

yes, that's what i mean. you can add the calorie field or any other to any of the in-ride dashboards/screens that you want to. since "average watts" is already calculated there's no fancy math needed, just multiply moving time by average watts.
it would be kind of sad to watch calories tick up so slowly relative to how quickly they can be ingested!

Yeah, would the calories in/out field be measured in bites per mile or bites per hour?

Reason enough to keep this metric out of sight.
