Kalkhoff from the past - my voyage of discovery and wallet emptying

[Dikki123]

Hi folks. Swapped my pushbike for a Kalkhoff (broken) allconnect c. 2008. Ive got a motor panasonic nua034ce but the connectors from the display unit are different to thos that are on the motor. Here for advice, pointers and hopefully a resonable cheap solution to getting the wheels spinning again.
Nice to meet you all.

Can you get your pushbike back? - no easy way to say this -
Mid to top of the range ebikes tend to come with closed proprietary control systems and limited access to spares and information through authorised dealers etc.

If you cant source a replacement display from kalkhoff even if you match the display to a generic make or find one with identical looks and dimensions, the chances are it lacks the kalkhoff version of firmware to communicate successfully with the rest of the control system. - which sounds perhaps? like as far as the previous owner got??

I could be wrong and it might be a simple wiring match up needed, pictures of the display and its connection and the motor/controller end too could be useful? at least if the wire count matches its worth a punt researching the pinouts..

edit or missing connecting cable ??

Thanks for the reply! Hmm. From the display unit I have 10 pins Whereas from the motor I have 12 pins - tI found this on ebay... any ideas?

Do all other inputs to the system such as throttle, brake sensors etc have their own dedicated sockets to plug into or perhaps are they expected to share the same 12 pin plug input as the display using the otherwise unpopulated pins?? the picture in the ad linked to certainly does not employ 12x connections regardless of the plug size employed.

How many actual wires are connected to your display 5X? 6x? generally there is
1 Battery voltage,
2 Key lock (Turns the system on when connected to pin #1 battery voltage)
3 ground,
4,5 Rx Tx??
6 ? 2nd wire in the pic suggests a wheel magnet speed sensor input too?

as it looks like your expected to build the plug yourself with the display in the ebay listing, the pinout should be available? if so wiring your current display up should be ok for testing with a bodge connection secured with blutack/tape.

if not already done google for a detailed manual for your display unit as it will list all the error conditions it can display when connected for further diagnostics if required As well as the required pinout info for connecting. (including .pdf in the search string should include a page count with relevant results so eliminating the few page intro manuals is easy..)

Our longest forum member made this information for you. I haven't looked at it for many years, but there is a lot of good information there that should be helpful for you:

Thanks for all this. I’ve returned the motor as i would have net been able to return it if I had chopped a connector off and I’ll be building up my Scott Sub30 XL MTB with a kit once I get the refund in. Been busy ebaying the parts to build up some wonga for the project too. I’ve got the 8 speed hub, front wheel, brakes and cables on there so far if it interests anyone. I’ve also got two decent batteries but apparently you can’t sell them on ebay. I suppose as the dodgy ones can blow up that makes sense.

Hi, just as well you returned the motor as it was a 36V unit & your 2008 vintage Kalkhoff almost certainly has a 26V motor and system. Additionally, if you found the right 36V battery, it would be to big for the 26V cradle. There is someone breaking a 26V Kalkhoff bike on FB if you are still interested on doing yours up. Best of luck

Thanks for this. How would I find the facebook ad for the person breaking the Kalkhoff please?

Excellent thanks

Please don't waste any more time and mony on this, you have virtually no hope of solving any electrical problem on it for the following reasons:

Your model isn't an All Connect, Kalkhoff only made two Panasonic motored models at that time, the Agattu and the Pro Connect.

Panasonic policy with bike motors is to supply sealed for life with a two year warranty, no spares and no technical support.

There was no one 26 volt unit, they were supplied in different versions according to the pedelec manufacturers wishes. This sometimes meant even different circuit boards encapsulated within and incompatible handlebar units.

And as advised above, there are no software updates for these old models.

As you'll see on my Panasonic support pages that Saneagle linked you to, it's really only possible to repair some mechanical faults such as bearings failures

The 26 volt Kalkhoff on FB being broken for spares may not even have a Panasonic motor, since Kalkhoff stopped using Panasonic units after a while, changing to very different ones made by German manufacturer Daum. They had even more problems.
