vPower - Bike Virtual Power

Description

The vPower data field app has been developed for those who are not fortunate enough to own an expensive power meter. Firstly, this is not 100% accurate. As you can imagine, there is a lot of variables at play to calculate power on the pedals accurately. This is my best attempt to take all these variables into consideration and developed the app with the following key features:</p><p></p><p>Version History</p>

What’s New

Added support for more devices and more indoor trainers (Jetblack Z1-Pro, Elite Fluid Elastogel (round unit), Elite Elastogel Force Mag 5 (3/5), Tacx Blue Motion (8/10))

Not sure this is the right place for writing this, but I can't find a better place. I was really excited when I found this data field even if I knew it would not be completely accurate. However, for me, vPower is of no use. On the road (trainer mode disabled), the power seems directly related to speed only. The faster I go, the higher the vPower value, regardless of the incline. So, going 20km/h uphill shows the same Power as going 20km/h downhill. Am I doing something wrong or is this the best the app can do?

Impossible de configurer les données. Je ne peut utiliser le "." ou "," pour paramétrer le poids du vélo ou le coefficient de résistance.

I used it for the first time today. It showed 400 Watts going down hill free wheeling and 1 watt grinding up a hill. What have I done wrong. Andy.

Mit einer Fenix 5 Plus kann man die Leistungsanzeige nicht nutzen. Die Leistung schwankt im Sekundentakt zwischen über 300 W und 80 W. Berg runter erzielt man ohne Trampeln über 800 W. Kann mir vorstellen dass Rohwerte von der Fenix genommen werden. Die nicht glatt gezogen und bereinigt wurden.

Does not work when i go up hill. it shows 1w or 0w. what can i do? Other way very good on flat roads. thank you

Hi Martin, please send me a copy of your fit file so that I can troubleshoot the calculation.

This is awesome! Good by 1k power meters! I didn’t think I’d ever own a power meter, but now I have one FOR FREE! Thank you for developing such an awesome app

Thank you for doing this. It's nice to have some type of metric without spending more money on a sensor for my bike than the cost of my bike.

I think I might have found the floating point problem. Mine in Germany has "," as decimal separator (as is normal here) but it won't let me input a "," only numbers and "." are accepted and then the "." seems to be ignored. If I leave the original "," and just edit the numbers it seems to work. Haven't used it yet just edited bike weight so far but I thought I'd leave that comment here hoping it helps.

Thanks mate. Yes I received feedback that localisation might be the problem. Will address in a new version.

Hello. I enter my tyre rolling resistance coefficient 0.006515 then i save and i synchronize but when i go back to settings the number has changed to 6515.000000. Is it normal? Thanks

I can't change to rolling resistance coefficient to decimal. I have uninstalled and reinstalled it but still doesn't work. I'm using a Huawei P20 lite but can't think that the phone is the problem.

Je n’arrive pas à trouver le champ sur ma Fenix5X. J’utilise déjà déjà deux camps de données. Est ce que c’est pour cette raison?

Developer Reply
June 11, 2020, Shane.Coetser

Veuillez vous assurer que le champ de données est installé sur votre appareil. Il devrait apparaître sous la liste "Installé" dans les paramètres de l'appareil sur votre téléphone. Sur votre montre, ce sera sous les champs ConnectIQ.

I have an old Elite Super Crono Fluid, i've seletcted Qubo Fluid ad i have 9% lower vPower vs the official Elite My E-training App (ex. 112W vs 122W). But i like it!

Bart Leemans

I can't change the tire rolling resistence coefficient. The field expects a long while the value is a decimal. Entering numbers doesn't work, neither does copy/paste.

Bart I just re-installed the application to simulate your issue. After installation I was able to change the value in the settings page on my iOS device. Can you confirm that you have a proper install and what phone you are using?

Just downloaded this yesterday and went for a short indoor spin today. I don’t have a power meter but the spin class I go to does and I have a decent idea of the kind of numbers I’m cranking. I’d say this tracks nicely and is maybe within 10% accuracy. Of course, trainer selection is crucial. I’m using rollers and selected the Peak Performance Omnium as the base and tweaked my bike weight upwards 50% from actual since my rollers have 1 more roller (3) vs the Omnium’s 2. I’ll probably have more to say after a couple more months with this.

Very good data field. Can you please get the Elite Crono Fluid added? I have the following Speed and Virtual Power rating from Elite. Speed(KMH) Power 10,35 20,88 30,190 40,325 50,505

I am getting very low power readings when going uphill (3-10%). I expect 150-180W based on Strava readings, but I am getting 10W or less. It looks like (bike+rider) weight (or grade) are being ignored altogether. I am using an Edge 520 plus (has barometer, not sure it uses it), and I have speed and cadence sensors. Any ideas? Could it be that it does not work if I am using feet/miles/pounds instead of metric units?

great app, it would be perfect if the watt data from the app can generate an estimated IF or can be integrated in garmin connect like for who has a power meter. these data will complete the statistic graphs with a lot of useful data!

Hey Shane, keep up the good job! Excellent app you have developed!!! All the best, Mike

Sometimes data is erratic, and spiky a lot. I did'nt understand the reason, better the developer make a simpler version, calculating using the weight, speed, slope real-time.

Nice app: it let’s me know instantly about my power and stores them in the Garmin Connect that I can analyze later!! It may be not perfect but it solves all my necessities!! Good job!!

I had a lot of expectations, but it looks as if the (default) settings are incorrect. I have peaks of more than 1900W and a average of almost 400W. My FTP is not even 200W, so this is far from realistic. Is there something with the (default) settings that needs to be adjusted to get more realistic values? Because I still hope it will work, I will rate it as "OK", but for now it does not work.

Great app..So..only a question...it's necessary imposted FTP value on device ?(Garmin Edge 520).. Thank you

Sorry, no statistics available yet.
