Odometer has stopped working - but speedo still works fine..

[FerberUser]

I am on my 2nd electric bike. This is a A2B Ferber, with torque sensor PAS. I've had it over 2 years, so out of warranty.
After the worst set of pot-holes this winter (I'm in the UK) of my cycling life, the odometer suddenly stopped working. I still get speed info, but not trip or total distance.
Any ideas? Is this going to be a component within the hub motor?

Well, in my professional opinion, ..... It's Broken.

As to whether it is a component in the hub motor, that would depend on exactly how the function is implemented on your particular e-bike, for that particular model, I have no clue. You have the bike and the owner's manual, also you could count the wires going into the motor and if there are only 8, three phase and five halls, that would leave no wires for a speedo unless it is wireless or bluetooth implemented, which again would require specific information about your particular model.

Is there an external sensor and spoke magnet installed? Does the setup menu on the LCD ask for wheel size? Does the speed info read out on the ebike LCD, or perhaps on another screen? I can't see it from here.

Is this a manual speedometer odometer? I would guess it's what it would be I don't see how a digital could go out like that. If it is a manual speedometer the gears or mostly made of plastic and it's possible they were stripped out causing it to stop working. If it is hooked up to your wheel hub and there was something wrong with it I would assume the speedometer would not work either. Because the speedometer is what turns the gears on the odometer to tell the mileage. However if it's digital someone else would definitely have to step in because I do not know much on LCD digital display

I was wondering sort of the same thing somebody messed with my wheel sensor moved it 1/8 of an inch, it still showed how many miles I went but O MPH.. I moved the sensor back closer now no problem I also placed a small rubber pad behind it so it is much harder to move again. However this is a external one like you described, not sure if he has the same set up. This happened today.

I have a Radrover rear hub 4" fat tire eMTB and my odometer stopped working a few weeks ago (odometer, mph, trip data). The LCD still shows PAS level, battery level, watts used, and still performs as normal when riding and motor cut-off speed still works. The broken sensor is contained within the hub motor and a replacement wheel would be around $300-$350.

I just put a wired Enkeeo bike computer that is USB rechargeable next to my LCD for $17. I was also able to input the last odometer reading from my Radrover into the Enkeeo as a starting point.

I tried a wireless odometer at first; but, the mph would go 00.0 every-time I would pedal using PAS (Cateye Padrone+)? The mph indicator would turn back on when coasting or if I used the throttle only.

That is odd I have a wireless unit, just type in the wheel size, it is only .05 mph off GPS. And i do not have any issues,MPH,max speed,Aveg. Speed. Total miles, and current MPH, I also paid 17.00 for mine, it is mounted to the front wheel, I have mine about 1/8" from the sensor magnet, for some reason any further away it does all kinds of crazy stuff. Your fix def. A smart one!

I still have the wireless Cateye Padrone+ I can put on my old pedal bike. I ended up misplacing where I put my removable CatEye Velo 9 LCD screen from that bike a few years ago.

Willing to bet, its where you left it. Joking aside I have put something somewhere more than once and forgot what I did with it. Just look for something else and you'll find it that's what I did.

Thank you for your reply. The owner's manual just says how to operate the bike, not how everything works, unfortunately. I'd love to lay my hands on a technical manual.
Speed and odometer all (usually) display on the one ebike LCD screen. No the setup does not require the user to input wheel size.
There are cables everywhere - including one that disappears into the rear frame by the rear axle (nothing to do with the brakes). Could this/Would this be a built-in but separate, external counting sensor?

OK, if the data was on the screen, then it must be going to the controller then LCD, or possibly, directly to the LCD. Track the wires from the LCD, usually they go straight to the controller. Next, track the wires from the controller. Should be light ones for brakes, throttle, and LCD going to the handlebars, then 3 heavier and 5 lighter going to the motor, and a red and black thick set to the battery. Track carefully all the light wires.

This is where wires going thru the frame are all neat and cool and stuff but are really a PITA.

Could be a regular speedo with a magnet on the spokes and sensor on the frame, often a generic replacement can be spliced in. If there is a sensor this problem can happen if it gets bumped out of position. They are VERY picky about position. There will be a sensor about 2 inches long and roughly the size of a skinny pencil, usually, the wire will be coming from that. Could be on the front or back wheel. Sensor will be on the frame, small magnet about the size of a small watch battery screwed or clamped to a spoke, will pass VERY CLOSE to the sensor.

If there is a ninth wire going into the motor axle, that should be the one, unless you get temperature data.

Do you happen to remember if the speedo readout went to zero if you coasted or turned the motor off? IIRC, this is common with DD hubs and there is no sensor, speed is calculated from the Hall sensors, I think. This doesn't usually break if the motor still works.
