SZZS specific CEF50-main thread (initial builds and troubleshooting related only)

[spokémon]

It usually has a voltage regulator, so if it supports 48v, it’ll support anything lower than it.
Data goes through can and pretty sure every ic in the display is 5v or 3.3v driven

Ok. that makes more sense

It's seem thar the DPC245 V3 is dedicated to use M820 in 48V

@patdam will yours not work with other voltages? 36v?

 

[un..inc]

Okay, if that's the case, I'll also delay my order a little until it's all been put in and tested.
I already have a super deluxe ultimate at home, but coil is worth a try, especially on an e-bike.
UDH is very important to me, so I'm happy to wait a few more weeks...
Does anyone have any news about the price and availability of the carbon battery cover?

are u sure few more weeks for their new triangle?

No, of course I'm not.
"A few" is also a matter of definition. It could be 6-8-10-12. I don't think they would communicate it if the construction wasn't already relatively advanced.
I can wait and am happy about every improvement.

It's going to take time.
UDH - chainstay modification
lower shock mount reposition, front frame modification - I would imagine they also have to look at the effects on suspension?

carbon battery case: my conversation on 2023-08-02
"3D print model will come back this week, then will try assembling, when all are ok, will open carbon mold, and it needs longer time."

 

[patdam]

It makes no sense.
I always thought the displays were auto-voltage-sensing (is that a thing?) or am I wrong?

sure, but may be previous versions can't manage 48V ? Only supposition following information collected (guy with previous rev of HMI who don't fuctioning with 48V, supplier who change proposal to DPC245 3.0 when battery power supply changed to 48V). Not a "truth true"

I suggested moving the shock mount, but Linda told me that she’s not sure engineers will do it since it’s modifying the front mould and that’s quite expensive.

UDH is almost ready as she told me, i’ll order that piece to replace my normal hanger.

Also, bare in mind to order the frame with cable holes to avoid using the headset ICR

I'm still torn about the headset.
It's actually quite cool not to have any visible cables on the frame, especially if you use axs.
On the other hand, it's a lot of work and it sucks when it doesn't fit 100%.
It's also annoying that you have to buy a new headset because the one that comes with it isn't waterproof.
In any case, I have agreed on a suitable colour with Linda. It could be cool.
I also can't imagine that they'll change anything else on the front triangle just because of a few guys who would like to ride coil. The kinematics would also change and that would be a huge ef
fort.

Fyi fresh from Linda:

Good day!



Yes, this month we can give UDH Derailleur hanger rear-triangle. thank you very much.

I guess we'll see when I get mine. she said she'll send it it'll really suck lemons if it only works on 48v

I run a DPC 245 V1 with M510 at 48V, but I‘m pretty sure this works on every voltage between 36 and 52. There is absolutely no reason to change this compatibility with a new revision. So don’t worry..

[Myalteregohamish]

Ask her to send you a set of allen key motor bolts. I asked her to send me 2x sets of motor bolts and she sent me the original with nylock nuts, and another set with allen key bolts.

Same here

Guys, 43V firmware

Guys, 43V firmware

any 36v or 48v firmware?

 

[brbr]

any 36v or 48v firmware?

Nope, she doesn’t want to give me the other fw…

 

[Lehr]

The motor makes a loud noise when going downhill, like there is a steel ball jiggling in the motor, do you guys have any of those?The seller replaced the motor with a brand new one for me, still the same problem

 

[Lehr]

It's like the chain is shaking and constantly pulling on the clutch.There are 4 videos in the zip

mine is ok. already check your freehub?

 

[JJ-NOR]

If i could ask, do someone have spec list, for parts that fit this frame?

I would like to start and buy the correct parts for CEF50 frame

Thanks

Unlucky. Hope they dont wanna make people just to use 43V batteries. Dont understand why Bafang came up with this non standard voltage.

Fork 150-160mm, rearshock 210x52.5/210x50 (air only), wheelset can be all 29er or mullet with 12x148 freehub. Other part U can choose what U need.

There’s a clank similar to shimano, that’s normal though. Are you sure it’s not the cables inside the down tube clanking against the wall of the frame?

That sounds similar to mine, I don’t think it’s an issue. But once you hear it you can’t unhear it. Just know that it’s normal.

The Fox Float X2 does not fit!
Which really sucks,now I need to find another shock.

That's a bummer. Got a pic to illustrate?

Nothing to do with suspension, cables, rear derailleur, if you remove the chain (clutch doesn't work) you'll notice it's quiet

I didn’t take pictures but the diameter is to big it hits the frame.
