Turbo Vado 2 4.0 or 5.0 or 6.0?

Perhaps add Pr to your ACE With the Cadence field as well!

Nope, the ACE is totally disconnected from the bike now and only provides GPS services on the bars. And it's very good at that.

That way I get the superior ride data and analysis I much prefer from the Specialized app running on my phone safe in my pocket. Everything else I normally need to see in the saddle, I get from 3 TCU pages.

Which reminds me of Alfer "The Ice Warrior", a friend of mine who zooms frozen rivers and lakes, and uses his Wahoo for GPS navigation only but he records his rides with the Strava app on the smartphone

It is his own photo where the ice gave up. The name of the river is, ironically, Cold Water

I just think the data for the last data row is wrong (Specialized fault). It looks good for other data rows.

Please elaborate. There's no typo.

Please elaborate. There's no typo.

Input rider's power 85 W, output motor power 300 W. It is just impossible for the SL 1.2 motor. Someone at Specialized had entered a wrong datum.

it's really not that complicated !! how much does the motor help you, as a function of how hard you pedal... and what's the MOST it will ever help you.

as far as i know every decent torque-sensor system from the big manufacturers works the same :

in the mission control days, specialized called the "how much help do you get as a percentage of your power" parameter "support". top slider of left image. the "what's the most support you get, no matter how hard you hammer it," was "peak power"

for TQ, middle image, "assist" is the same concept as support, and max is the same as peak. for mahle, Pp is "peak power" and "Re" is the same as specialized's support and TQ's assist.

the only meaningful differences are :

1 whether they include an acceleration parameter - specialized does not for road/gravel/hybrid bikes, the others do. that's how quickly the motor ramps from no/low assist to high.
2 whether assist is a direct percentage of your pedaling power, as in the TQ example where it's 200% of your power, no other multipliers or factors. in order to keep the scale from 0 to 100 on all their bikes, specialized added the support factor, which is hidden, and ranges from 1.8 or 2.0 to 3.x plus depending on the bike. that's where the confusion comes in, because people set it to 100% thinking if they put in 100w, the motor also puts in 100w, when in fact it puts in 200w or 360w or whatever.

this is totally just a software thing, they could change it if they felt like it... and keep in mind the SL system was co-designed by specialized and mahle, the full power ones by specialized and brose, so really there isn't anything new here that specialized has done other than what they call the terms and set the scales.

Interesting way to look at it. Personally, since I have a Pr (rider power) readout on my SL's top bar — and am getting to know what 100, 150, 200, 350, 300W, and so on feel like — I'd much prefer to see a straight percentage of Pr.

Now, if I wanted to add a TCU page, I could see Pr, Pm, and "power ratio" (Pm/Pr?) at once. Will test that tomorrow!

i probably would too... if i looked at motor power much during the ride!

in part to harmonize the experience between bikes i don't look at motor power much any more. cadence, rider power, pedal balance, heart rate, speed, ride time, that's really all i want and need. i have the displays set up exactly the same on e-bike and non e-bike. with the creo i did fool around a bit with adding some of the ebike fields but just did not find it meaningful while riding. cool to look at after and initially to understand for sure what the bike is doing, and maybe useful for estimating range?

i have my data screen set like this. there's another page with map and most of the same data, another for climbing showing gradients and so on, one with lap data, and one with GPS only info for rides on the commuter!

I'd normally want to see much the same in the saddle (except pedal balance).

But now I have some detective work to do. Won't hurt to add a TCU page for now, but I generally want just 3 to flip through.

Spend 90% of my time on this TCU page. The 50/50 is the assist mode.
