The First Negative Wahoo ELEMNT Roam Ride Report
If you ride a bike with no sensors, the Roam solely depends on its GPS, which might be inaccurate but it works. Add a speed sensor (it is actually a wheel RPM sensor) to get more accurate distance measurement; in case the sensor gets disconnected, Roam will switch to the no-sensor mode, and everything is still fine. It is not so nice when you have connected your e-bike as a sensor:
Case A: Let us assume the
entire e-bike gets disconnected for any reason: the Roam will switch to its bare bone version, which is fine (had such a situation once)
Case B: Let us assume only the wheel RPM sensor of the e-bike got disconnected because of some reason (probably a software bug or whatever). In such a situation, you still can see the E-Bike Reported Speed, Battery Level %, Cadence but Biker's Power value becomes
zero. However, the Roam thinks the e-bike is stationary, and gets into Auto-Stop, meaning the Distance and Time variables get frozen, and your ride is not recorded anymore. What a bummer!

I should always keep BLEvo running on my smartphone in the back pocket for backup purposes! The Roam deprived me of 17 km of my Strava ride data, the data I had to re-create manually post ride. Interestingly, the return ride was served by the Roam without any hiccups. Yes, I could see a large "LEV Motor Error" message on the ELEMNT twice. What error?! No error has been ever reported for my Vado SL before. (I think the Roam is the error really...)
I don't complain. Things happen. I only need to learn to keep a backup device with me. I also intend to disable the Auto-Stop. Besides, the calibrated perfect Schwalbe Smart Sam 37-622 wheel circumference has been 2159 mm (as opposed to the default value of 2180 mm for 38-622).
