So is that the CEF50 frame small or med size build...painted red?
Linda said it was both a power selector display and a power button. Apparently it can be used in conjunction with the handlebar mounted remote selector/power button. So, I believe, since most NEED the remote more than the frame display...it's redundant or Linda was incorrect and it's just a power button. Hopefully, it's just a power button integrated into the frame for convenience.Did anyone ever get an answer about that top tube power button (i.e what they will ship and how it will work)?
Sure. I get they're likely compatible because of CANBus firmware...but there might be some "crosstalk" which is confusing.Since the new Bafang controls are CANBUS I think they will all be compatible. Unlike a serial controller which must be connected directly to a device, like a display or remote control, to a unique port just for it the canbus is a network. Just like the internet each device has a unique address. Each device only responds to requests addressed to it. So you should be able to have multiple remotes and displays and each would have it's own address and if a request for an assist change is sent to the motor it knows which device sent the request. If a device requests speed info from the motor it would be responded to without confusion as to which device requested the info. Now there is a million ways that you can make things so they can't work together but the purpose of canbus is so that it can. The canbus cabling is noise resistant also so less errors. TMI?
Does the remote with 5 power modes tuned to the M820 override the integrated power display's 3 power modes.? I hope so.Sure. I get they're likely compatible because of CANBus firmware...but there might be some "crosstalk" which is confusing.
Potential dilemma: the integrated display has confirmed 3-power mode selectors different colored hues, the remote has 5-power mode selectors, 5 bars to match the M820 power modes: walk, eco, trail, boost, rocky mode, 3 to 5 is not 1:1 compatibly...right?
If not just disable and remove the frame power display and patch the hole or mount a smart phone mount to hide the hole. This was discussed early in thread.Does the remote with 5 power modes tuned to the M820 override the integrated power display's 3 power modes.? I hope so.

But Team CEF50, others would benefit with clarification. Ask Linda to do a short video demo of how both of the power selectors work...and then please post it here?
I'm still waiting on shock mount hardware and frame weight answers...it would be nice for others to know before they ship! Go team CEF50!
Ok great! It would in theory make sense that no "crosstalk" will occur. But in practice they are two, separate, competing power display systems. It's not necessary to have the extra weight (209-300 g for cable and display?) and redundancy of the integrated power system. Plus, put an extra hole in the fame when not needed? This doesn't pique your curiosity a little? Especially where weight is the essential element of a "light weight" E-mtb build?In my experience with other Bafang motors bbshd, the display can be configured for 5 or 9 levels of assistance. So the determination of the "status" is determined by the display. So it gets a value from the controller and interprets the value. So you should be able to use the top tube assist and the remote for controlling assist together. Each should change to show the current status even if modified by the other device. Since the remotes will query the motor to get the assist level they should both change indication when either changes the assist level.
It would be nice to get the shock hardware spec so we can order the parts. The worst part of DIY bike builds is waiting for some little part that needs to come from china. It is really wise to get your ducks in a row and get everything on it's way in advance if you can.
I also ordered a 210x55 which may not work with 29er wheels.
There is no possibility of crosstalk but there certainly is no need for two displays. The top tube is the simplest integrated display, which is also probably the cheapest, but who wants to take their hands off the bars to change assist?Ok great!

Can we minimally agree that it's at best the integrated display is an added, unnecessary power button. And at worst it's an extra weight-added appendage that might crosstalk? Either way, the standard M820 kit uses the HID 181 power remote. It's not on the LCE930 system.
Ok we agree. It's redundant and adds extra weight unnecessarily.There is no possibility of crosstalk but there certainly is no need for two displays.

I ordered the DPC-245 bluetooth because it is most like my minialist shimano steps display on the Orbea. I don't like the chunky look of the DPE-18.
They are listed on Aliexpress but I have asked Linda to supply them, waiting for a response.Ok we agree. It's redundant and adds extra weight unnecessarily.
I agree on the DPC-245, I've tried to order it through greenbikekit, they are available to purchase now?
Here is a shot with only the top tube display/assist control.

That's a good idea from Linda on DPC-245! AliExpress is usually behind in availability...They are listed on Aliexpress but I have asked Linda to supply them, waiting for a response.
I am getting the FT100 battery so she will needs to talk to Bafang about that and hopefully the DPC-245 at the same timeThat's a good idea from Linda on DPC-245! AliExpress is usually behind in availability...
Just revisiting the earliest thread topic related to this discussion...If this whole integrated display unit weighs more than 200 g, I think I might just patch over the frame hole as stated previously in order to reduce the overall bike build...sorry but it's just mind-blowing that two fully independent systems exist in a marketed light-weight e-mtb build...which is the whole damn point Now add to the matter that the absence of a thumb remote on an E-mtb wasn't a priori, that it was better to start poking holes in the frame is just engineering madness by the CEF50 makers.I am getting the FT100 battery so she will need to talk to Bafang about that and hopefully the DPC-245 at the same time
Wait. Is the purple arrow that I drew point toward a wired thumb power selector?Here is a shot with only the top tube display/assist control.

Yep...brake clamp. Was hoping for the best...I think it just the brake lever clamp (both sides)
Yes I can see the inexperienced customer thinking the top tube assist is clean and cheap but anyone who has ridden would discard it as an option immediately. Unless you are a commuter I suppose.
But an Enduro bike? Ya I am going to take my hand off the bars to change my assist in the middle of gnarly down.
Definitely a bad choice by the design team.
So maybe a goo holder?
Do you think both parts needs to be charged? Screen and thumb control?
These aren't wireless, so no small unit batteries. They will connect to the main battery connectors hidden in the downtube.Do you think both parts needs to be charged? Screen and thumb control?
I thought that was wireless, so it might be a good option indeedThese aren't wireless, so no small unit batteries. They will connect to the main battery connectors hidden in the downtube.
I personally prefer to see a small screen instead of the bulky high profile remote.I was wondering what was the best option with the DP E181
