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

I am too poor for such luxuries

I hear on the cash But given our current climatological dilemma, I'm gonna burn my juice before we all evaporate...at least here in the desert summers. New record 40+ days straight 110+°F and a true 100+°F for a looong 4 month summer.

Excellent sonof you can put specs of each would be great so can try get them made in Europe. You provide is US based? He ships worldwide?

I just spoke with Derrick at Huk Tech. He does ship internationally.

He doesn't do steel.

However he does recommended doing the two main pivot screws that bear the load in Titanium: the upper rocker arm and the lower frame pivot one, and then the remaining 4 linkage screws in aluminum.

I sent him one of my original OEM screws that I found in my shed via regular mail. I don't know what his costs will be, but usually the first order is more expensive due to CAD design time costs than those that follow.

I know on my Vitus E-Mythique the reduced power setting is below 10%. It has a Bafang M510 but with Vitus' own tuning. So it must be an easy feature to change.

Pinner Machine out of Canada is another good source for custom hardware. Guy does amazing work mostly by hand.

You can change the assist power levels to anything you want but you need the Bafang dealer tool. Which some folks have acquired

Hello guys,

Hi, I bought this on the forum some time ago there were indications of the measurements I always have to receive the frame for verification but one of the forum changed it with these measurements

 

[TommyR]

Hey y’all, it appears my frame has shipped. I’ve been provided a tracking number starting with HX_______, but was also provided a UPS Ground tracking number.

I assume the UPS number is for when the package arrives to the US? And the HX number is the ocean freight? Can anyone confirm? Also, how can I track my ocean shipment? The link I have is in Chinese.

Thanks!
Tommy

 

[mike_kelly]

You need to ask for the ship name and date of sailing. Then there are apps on the internet to track marine transport. You can also get status info at the ports website it is coming into.

 

[TommyR]

Thanks! I’ve asked about the ship name. One of the few English words in the documents I received was “Mackenzie 5E”. I’m curious if that may be the ship’s name. I searched and there is a ship named Mackenzie near China right now so maybe that’s it?

Yep, that’s the one I found! Now I’m looking for a free app or site where I can track its itinerary. If anyone has a suggestion, I’m all ears.

Hello guys,

I am running a HEPPE L183 M12x1.0 TL30 thru axle into my SRAM GX Tramission.

I would not run anything longer as the end of the axle almost bottoms out in the Transmission retaining bolt.

I currently have a bike built with the LCE930 frame with the M820 motor and am really enjoying it but would like to have a bigger battery for long ride days or out-of-town MTB trips (Bentonville, Colorado, etc.). I'm hoping you guys could answer a couple of questions for me:

• The CEF50 lacks a seat stay bridge on the frame and I am concerned that the frame will be flexy. My current LCE930 frame has a seat stay bridge and I don't notice any excessive lateral flex. I'm a full-figured man of 205 pounds so I have to ask.
• With the custom 720 Wh battery from SZZS, what information is missing due to the 720Wh battery not being CANBUS? I can currently see the state of each cell in the Bafang battery. Will it still be able to give me range estimates? Battery charge percentages?
• Lastly, I have the Bafang BT F014 (410Wh) battery and was wondering if it would fit the CEF50 frame? I ask because I can buy the frame now and reuse the motor/battery until I can buy the larger 720 Wh battery (and flash my motor to 48v). Just thinking out loud on this one.

Thanks,
David

My CEF50 has no perceptible flex with me 170lbs/6'4" and I have nearly maxed out the 170mm/165mm travel the best I can do around here in Dallas. I can't help you on the battery questions as I make my own but do not think Bafang makes batteries for different bike brands - just their motors.

From a DIY standpoint, the CEF50 has a great beginner battery compartment (bigger) - LCE930 is a bit more of a challenge (narrower) as I understand it. LCE930 was my first choice but they do not have a XL size.

 

[mike_kelly]

Bafang does make batteries like the BT-F014. The Bafang catalog lists all the batteries they make. Without canbus you will only see the estimated remain charge on the display. Just ask LInda or Jean of the Ft-014 will fit the CEF50.

I cannot say if battery fits or not, but as a temporary improvement at least you can flash a 36V firmware for your current setup. That will allow you to take more juice out of the battery. It will also give you somewhat more maximum power. Downside is battery percentge will not be correct, I have only tested this with 48V battery/43V firmware diy battery, so not exactly sure how the canbus will affect this.

HELLO Guy
the frame kit etc.should arrive next week I hope.
I modified a 216x63 shock absorber
it now measures 212\213mm
offset bushings, travel reducer, bringing it to 53 mm.
I will carry out tests by increasing the travel.
Some photos of the work.
I accept suggestions and criticisms, let me know your point of view.

It sounds like you should be fine. It appears a p nothing of greater than 210mm will force interference between the chain stay and frame so you’re fine there. And your 53mm of travel should clear from all I’ve read. I’m targeting similar stroke of 52.5mm.
