Help! Replacement DP CO7.CAN wanted.

[wilks55]

Apologies, the five pin connector shown is incorrect, the one I need has this type.

 

[cyclebuddy]

and I'm faced with a relatively intractable problem that I've never experienced before

The part you need is a really common part used across a number of e-bike manufacturers - it's not obscure, particularly difficult to obtain, or exclusive to Eskute. As far as I can see, your Eskutes use the DPC07 CAN display with the Bafang M200 motor. One of my own bikes uses the identical looking DPC07 UART display with the Bafang M400 motor.

There are dealers who know this stuff backwards... Forum members like Woosh in Southend or Brighton E-bikes are two members here that could probably source the part and likely fit it too if you ask nicely and you're close to them (we don't know where you are).

I'd still first email Bafang support with a picture of your device serial number to see if they can help you with a warranty claim.

Thank you everyone for your advice. I shall email Bafang with all the details.

BEB oe woosh won't source the part as they wil have to deal in volumes and not just a one off purchase, it is the way china does business.

My thinking was that Woosh already use the DPC07 display on their own Rambla bike here. Knowing how helpful Woosh always are, they may have access to or a source for spares for their own warranty replacement? There's a thread here on the forum where BEB swapped out a DPC07 for one of their own stock upgraded Bafang colour displays; that may be an option too. As experienced users and resellers of Bafang drive systems, in the absence of Eskute actually giving a damn, I'm only suggesting there are many knowledgable Bafang dealers/resellers about who'd likely want to help.

What is unclear, in hindsight, is what is actually wrong with the OP's display? Is the problem actually the display? The OP seems confident it is, but a dead or malfunctioning display could equally be a comms/power issue with the controller... or even just a loose plug on that board? It hasn't been said. Just curious.

Many thanks for that. I connected the controller on my bike to the feed on my wife's, and my controller lit up. Does this not suggest that the problem is my wife's controller that's at fault. This is all new to me and had I had adequate support from Eskute, we could have worked through the problem. I understand that controller malfunction is pretty rare so I appreciate your comments. I will contact Woosh anyway, speaking to a helpful, friendly pedelec dealer would be a tonic in itself!

You're lucky to have bought two bikes where you can easily swap-out components to fault find, otherwise you'd be scratching your head!

For clarity, the display is the stuff on the handlebars - buttons and screen - which communicates with the controller. The controller is a separate logic board which, in your case as a crank-driven Bafang M200, is inside the motor (you'd need to remove the left pedal crank and motor cover to access it). The controller is the brains that interprets what you want to do from the display buttons as well as signals from a speed sensor and how much pressure you're putting on the pedals, and tells the motor what to do. They communicate digitally using UART on older systems like mine, or by CANbus, which is the newer standard as yours seems to be.

If you swapped the display over from your other bike and all worked, then yes, I'd say the display is at fault too.

For your future reference, as Eskute sell direct and don't actually have any dealers(?): CANbus systems usually require plugging in to a dealer's PC software system to fully diagnose faults (Besst). Volt E-bikes (who AFAIK assemble their e-bikes in Milton Keynes) have 100 nationwide dealers and use the same Bafang M200 drive on their Connect and Regent e-bike models. E-bike retailers selling those Volt models will likely have the Bafang diagnostics software (in case you ever need it).

Thanks for that very useful information. I seem to have found the access to pedelec information that I had no idea existed, I just wish I could turn the clock back to November 2021 and was looking to buy two pedelecs! The irony is that all the problems I've had, with the exception of this one could be fixed by a trained chimpanzee so why Eskute don't up their game and offer an acceptable level of support is beyond me.

If your bike works/operates fine with your wifes bikes display then the fault is else where.
A display not lighting up should indicate a power supply issue and no battery power getting thru, does her battery work on your bike ?
If so then either the main trunk cable or possibly the motors controller is at fault.
If the battery works on your bike try swapping out if poss the main trunk cable from controller to display to rule that out, then it only leaves the motor controller as the issue.

If her battery doesn't work then likely it is a blown internal fuse, some batteries have a grommet to access any fuse.

Sadly with CANbus one needs a dealer other sourcing parts or fault finding isn't easy, in your case you have two identical bikes so one shoul dbe able to swap components to find which has failed.
