Wrong display sent from vendor

[wntrhwk68]

(Just an FYI, I have posted on another forum, and I have refined my question here to include better information)

Hello, I have had a TBI and just went through cancer treatment, so don't beat me up too much, if you need clarification on something I will give you what I know. I purchased a full suspension 60v, 1500w bike back in Februrary. It finally arrived 29 days ago, non-functioning. In PAS 1, or under twist throttle, it cuts out, cant get above 8mph. Also came, out of the box, with 73 miles on the display. The vendor did not put the milage and power issues together. After countless emails and phone calls over the last 29 days I was told I had the wrong display, from the factory, and they would be sending a replacement. After waiting so long to get the bike, and getting zero support up to now, I am going to assume I am on my own. After reading reviews on the bike and company, I guess I am just not very lucky, most people really like the bike and the company. On to my question, I am going to assume for some reason I have fallen in some sort of crack here where I am not going to get the correct display, or any kind of support. Can anyone help with finding a display that will work with this bike, specifically a 60v with the proper connector. As you can see the connector for the display is not "standard. Feel free to ask question, I will answer what I can but because of the lack of contact from the vendor I don't have much in the way of technical information. Appreciate any information that will get this $2k paper weight on the trails.

The display is a common KT (Kunteng) LCD3. The model number indicates it’s good up to 48v nominal. You’ll likely need a 60v/72v version, assuming that by wrong display they mean wrong voltage (and not wrong brand). If you are going to fix it yourself, then it wouldn’t hurt to verify exactly what controller you have, so follow the other end of the connector to locate the controller, likely a silver box. If you can post a pic of the label it would be helpful.

E-HP, thx for your help.

Well it’s a KT. That connector is pretty unique. It may be a challenge to find an LCD3 that uses it, maybe just for the ebike maker. What model bike is it?

I did find the connector, so that’s a start.

E-HP, thx for that, now i need to figure out whcih wire goes where. As far as the identy, at this point I would rather not. The way this year has gone so far the vendor would probably sue me for liable or slander or something if they knew I was talking about their company. I would be willing to discuss offline, just not in such a big forum, hope you understand.

Check out the KT- lcd-03 manual.. unless hobbled by custom f/w you should be able to check and set the relevant parameters and possibly get your bike up and running, as the only way the controller display being 'wrong' makes sense is if the correct display is set to configure your controller correctly and the display you have is simply configured for a different bike.. ( or slipped through without getting set up?)


As pointed out above your bike operatives at a higher voltage than most kt controllers so the standard manual and its section on voltage selection will not reflect your bikes settings correctly..

fill, even though the back of the displays says it only goes to 48v, you think it might still work with the 60v controller? I have not found a way to get into a "config" screen on the display, the only thing I can change is speed, wheel size and how the motor output is displayed, so that brings me back to where I am now.

Er, No, I missed that point in both your pic and E-HP's post.. yeah wrong voltage is another mighty fine reason for it being the wrong display doh!

Google backs up the display gets the battery voltage, so a fully charged battery may? have done some damage already?

but if only overvoltage side effects that didnt damage components?? It might be worth trying again with a battery discharged below 54v (if viable for your battery) as thats within expected voltage levels for a 48v display, and may elicit different behavior ??

If it does work with a battery of diminished voltage you may be able to set a configuration, remove the display, check the plug pinout and short the red (battery voltage wire) with the blue control wire terminal in the controller socket and run the controller on the last set parameters without the wrong display for throttle control.

I doubt they would say they will send a replacement out if they are not going to do so as its just as easy to tell you to F-Off so its probably in transit on the slow boat and will arrive eventually,

ebay #264399706622 (ebay.co.uk) Chinese seller.. sell a 60v or 72v version with a 'standard' connector requiring a bit of a solder job to connect if nothing ever arrives.
