Steef Klonoa Posted March 16, 2019 Share Posted March 16, 2019 I have about 830 miles on my Z10 now. Rode it to work today and gave it a charge before getting back on. There is now a noticeable old computer sound to it, like it is dialing up the internet. When I disconnect and reconnect the bluetooth the sound changes, but it is still there. I have tried restarting my phone and restarting the Z10 but the sound hasn't gone away. I purchased it at eWheels back in October. @Jason McNeil have you run into this issue before? @Marty Backe curious to know if you've seen this before on one of your wheels. Could it be really strong internet interference, or is this unsafe to ride now? It seems to ride normal. Link to comment Share on other sites More sharing options...

But if I heard it maybe I'd have something intelligent to say. Link to comment Share on other sites More sharing options...

Steef Klonoa Posted March 17, 2019 Author Share Posted March 17, 2019 It does sound more normal now, maybe a quirk of the new firmware or something. What's funny is that it lasted a good portion of the day, all the way from work and then it still had a similar sound at home. There is still a "beep" every now and then.

mrelwood Posted March 17, 2019 Share Posted March 17, 2019 Does the sound go away when the tire rotates? EUCs in general make funny sounds when the electric current slowly changes from coil to coil in the (almost) stationary motor. The sound on the video reminds me of that. However, it does not explain why the sound is suddenly audible to you. Link to comment Share on other sites More sharing options...
Smoother Posted March 17, 2019 Share Posted March 17, 2019 That's 2400 Baud. You should ask Jason for an upgrade to 5600. But seriously, it sounds (no pun intended) that something has let go on your mother board (rocket scientist, I know!) Swapping out one of the boards (I think the Z series has several boards inside) will be the most likely route. Jason will advise, and Jason will act, and you will be made whole again. Personally I would worry about riding it, not knowing what has changed to create that noise. The offending component could be on it's last legs, and when those let go, so might yours. If you start hearing "The number you have dialed is not a working number. Please hang up and dial again" you have an entirely different problem.

Steef Klonoa Posted March 17, 2019 Author Share Posted March 17, 2019 @Marty Backe It could be coming from the speaker, but I can't really tell. @mrelwood the sound doesn't go away when the wheel spins. It's still audible like you hear in the video, just a bit fainter this morning. Link to comment Share on other sites More sharing options...

Also, does the sound change as you move the wheel back and forth? I hear essentially nothing from my wheel. The Z10 is one of the quietest wheels available.

Trying the speakers is a good idea, I will check when I get home from work. The sound does change a bit while moving, but its still similar to what you can hear in the video. My friend has a Z10 so luckily we can compare and his has not made sound like this. Link to comment Share on other sites More sharing options...
Steef Klonoa Posted March 17, 2019 Author Share Posted March 17, 2019 @Marty Backe the speakers don't seem to be effected at all. When I turned down my music the sound is still there. Link to comment Share on other sites More sharing options...

If it were my Z10, I would continue riding but if I ever noticed any strange handling behavior, then I would stop. Link to comment Share on other sites More sharing options...

Steef Klonoa Posted March 18, 2019 Author Share Posted March 18, 2019 @Marty Backe I went for a 15-20 mile run earlier and traded wheels with my friend for a bit. Both perform exactly the same. I'm thinking this might be an issue not related to essential functions. @houseofjob you've taken these apart, curious to know if you have any ideas on what would cause this? @EUCMania I think that would void my warranty.

Hard to tell what's going on exactly without opening up the wheel. I'm guessing a connector could have come loose, causing some kind of interference (?) But that's again just me guessing wIthout peeking under the hood. If you do open, I will would try checking the Bluetooth and music speaker module connectors. How much abuse has the wheel seen? (specifically water) And this doesn't affect the ride, right? Link to comment Share on other sites More sharing options...

The ride is not affected at all, I compared yesterday to my friend's Z10. I've been riding it through the New england winter here and will often commute 12 miles to work on it. I don't bring it out when it's raining, but its been out quite a few times when the ground is wet. Link to comment Share on other sites More sharing options...

esaj Posted April 20, 2019 Share Posted April 20, 2019 If you can disconnect the speakers and the sound vanishes, it's probably the audio amp or speaker wires picking up interference from somewhere (could be the motor PWM frequency / sub-harmonic or serial data transfer somewhere on the PCBs/wiring). I don't know for sure, but I think the volume adjusting with Bluetooth only affects the transmitting end here, the audio amp would still be amplifying any interference it receives even when you turn the volume down on your phone.

Steef Klonoa Posted April 20, 2019 Author Share Posted April 20, 2019 @esaj thanks for the input! I'm assuming since it has 400 miles on it since the noise started, that this interference is not going to worsen or cause a board failure. I'm keeping a close eye on it and will send it in to ewheels at some point, it is still under warranty. Link to comment Share on other sites More sharing options...
