I have been doing more work with this bike. I have recorded several different scenarios and used the same Audacity audio edit/analysis program to display the spectrograms. I have also recorded short (~1min) videos of the program scanning a marker through the audio and there are explanations of...

Audio file and graphical depiction of the spectrum. There is a (very) short clip that shows the background, or natural, noise of the bike with no assist for a few seconds, then power on for a few more seconds and finally the torque on the pedals is backed off. The noise of the motor running at...

Yes, it is. The mechanic takes it out for a short ride, brings it back, says it sounds like an ebike then reports to Specialized he can find nothing wrong.

Hi - I have a Dec 2020 Vado 3 with 1400 miles on the clock. The motor has become very noisy at low powers/torque levels. I think this is backlash in the internal gear(s). With no assist, there is no transmission noise at all - no chain or other noises. When pulling (accelerating or climbing)...

No. Too right. I've been happy so far. The ebike integration will be the icing on the cake, but I'm puzzled over the lack of reports. Perhaps the bike has a fault...

Thanks Stefan. I'm trying to understand why the latest HH K2 software incorrectly interprets motor data from Ant + LEV but is OK with rider power on Ant +. Hopefully they'll sort it

And is there anyone out there who can tell me the difference between Ant+ and Ant+ LEV, if there is any, other than a naming distinction for the likes of a heart rate monitor or pedal sensors as opposed to e-bike motor power, torque etc...

Is there no one else out there using a Karoo 2 and Vado 3?

Hammerhead recently integrated ebike sensors into their Karoo 2 GPS but it's not working on my bike (2020 Vado 3). I can expand, but I'm interested to see who has used this function before I go into any real detail. In essence, however... The K2 used to see the power/cadence and speed/cadence...

I've done some more study on this now and I think there are some problems with the Blevo app when it reports assistance levels, and therefore what it reports when it calculates the data. Bear in mind this is on a Vado 3, not one the bikes for which the app was written. Below is the thumbnail...

Thanks for the reply Stefan. Just a quick time limited response at the moment. Your maths are perfectly understandable and I will experiment further. What I still don’t get, is why in the second graph, when 0% power is set (as opposed to OFF) the motor still generates power. More later…

Hi - I have a Vado 3 and I use BLEvo. Since I bought it, I have had peak power set to 100% on all three modes and assistance levels (usually) of 15%, 50% and 75%. In the Trail and Turbo modes, I can feel the bike giving max power to assist but in the Eco mode, I never get the max power. If I...

Hi - I'm just getting started with e-bikes. We have a pair of Vado 3 machines and I have invested in the BLEvo app which is quite fun. Lots to learn and many questions to ask. I look forward to the interactions with this forum.
