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

[TCFlowClyde]

I think Tom posted it in the ICR headset thread or I have a shot with the other components in the Spec thread.
I did get this email from Linda showing the top cap filed to reduce risk of cutting the cables.
Yes in the main spec thread about third picture down shows the headset pieces but not in high res.

That's a nice big opening with a rubber/plastic grommet insert.

One thing to consider is that the DPC245 display plugs (green triangular male end) is fairly sizable. It will easily fit and feed through the stock cap opening. And now that they blunted the sharp edges...less work on the build.

However, on some of the aftermarket ICR headsets, you may have to drill out one of the more narrow cable ports to pass through the connector and reseal it with your favorite method. It's a little bit of an extra pain maybe?

Almost there, today I should receive the RT-EM600 rear disc that includes the magnet for the speed sensor (magnet didnt came :/ ). Then a test ride.
it doesnt have the final wheels (1900g is this set) nor the carbon handlebar, lighter cranks or seat but it weighted 18.4k
Im pretty sure that it can loose 1 more kilo after the upgrades.

CEF50 EMTB Frame grommets and Battery support by matioz

There are four stl's included.GrommetFrame: this goes just behind the motor and protects it from getting dust/water from the cables that go to the rear. Printed in TPUHeadsetRubber: This one needs to be trimmed a lil, I'll upload a modified version afterwards to avoid trimming it, but it works...

Here are all the STLs I used for the CEF50 frame, grommets and BT F014 battery support, any doubt or modification just let me know and i'll asses it

18.4kg! wow, well done, with the piggyback shock and "mid-heavy" wheels !

18.4kg! wow, well done, with the piggyback shock and "mid-heavy" wheels !

I'm quite impressed also!

Carbon cranks + lighter chainring: 200g less
Carbon wheelset: 400g less
Renthal carbon: 100g less
XT derailleur: 30g less
Saddle: 200g less (I use a 110g one always)
XT Discs: 100g less

That would make a nice 1030g less, resulting in what I was aiming, a 17.5k emtb

I will be drawing the top tube button cover gasket also today and uploading it on thingiverse. Want to make the bike as rainproof as possible, although here it never rains it'll benefit everyone that has a CEF50 in a more humid place.

After bench testing the DP180 controller was throwing a 21 error (speed sensor).
I thought it was the custom magnet I was using but no, looks like the connector that's hidden inside the rear triangle was incorrectly connected (sideways). Had to straighten a pin, connect it properly and also added a layer of electrical tape so it keep tightly connected. I'll just order a spare "SR SD071.02" just in case.

Now tested it and works properly in the bench, even walk mode and error not appearing anymore. Either way since amazon is delivering the rear disc with magnet today I'll wait for it to arrive, change it and go for the first ride.

Photos don't make justice to the frame, but honestly its REALLY good looking, I love it.

To enable walk mode: Go to the no assistance mode, click twice the "down" button but on the second click keep it pushed. walk mode will be on until you stop maintaining the button pressed.

Weird that Miranda claims the lightest yet does not print what the weight is of the cranks.

First ride:
The engine has A LOT of power, really feels like a full powered emtb.
Need to get customed to the suspension since its quite dif to my other bike

Had some issues that the speed sensor moved and was failing but after retightening it everything went ok.
30km, 960m elevation and had 3 leds remaining, using mostly the second level since that was enough for me to go up at 15km/h

What full-powered motor could you compare it to?

 

[TCFlowClyde]

Any "Rocky" mode short term boost available?

Rocky boost mode?

Noise during climbs and turbo modes?

Thanks in advance.

30k on a 410wh seems like good range!

So curious about Rocky boost mode

 

[TCFlowClyde]

So curious about Rocky boost mode

I suspect it may not exist. There are 5 power mode levels (on the DPC245 display)...so it would be easier just to click up a few modes to boost.

But the DPC-181 might have it. I ordered the 181 to test it out.

Side note: I've been using the DPC-245 on my M600....it's a major upgrade from the old DPC-242!

But yes curious if the newer tuning protocols just eliminate it altogether.
