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

If you can do 600w you are more of a stud then I thought.

In turbo mode too! I guess you could just put it zero power mode and pedal. The watts will readout for your work output?

 

[mike_kelly]

No it is reading the current and voltage at the motor. Nothing to do with the rider, unfortunately.

 

[Stephen B]

How long can you maintain that high of an power output?

Edit
Sorry I thought you were talking about rider input power.

 

[TCFlowClyde]

I did max pedaling just for a few seconds in full boost power mode.

Are u meaning calories burned?

 

[mike_kelly]

It is interesting for the peak output of the motor. Continuous it is supposed to be a 250w motor but I noticed that the Bafang battery spec states a max output current of 18amps from the battery. Which would mean an absolute max possibilty of 650w peak for a short time. So that looks in line with what you were reading.

 

[TCFlowClyde]

Anybody see the fully water resistant ICR cap and stem combo? Could be the one!

 

[mike_kelly]

Since it is just the cap, and I already have a stem, it is too expensive for my blood.

Power is measured in watts, for instance Peter Sagan is the strongest cyclist ever , I think during a tour of Italy sprint he maintained around 440w for 20 minutes and in another peaked at over 1400w

Wow so light. If U have pictures when weighing pls share. What components use?

1. Miranda FB connecting rods really suited me, they are a little wider and I like it.
2. Fork Rockshox Lyric select 170.
3. Rear shock absorber Sidlux 210x50.
4. Rear derailleur X01.
5. Wheels carbon, dt240, sapim.
6. maxxis dissector tires 29x2.4 EXO (Exo + is heavier).
7. 10ah battery - 1.6kg.
8. Carbon steering wheel. The saddle and dropper are carbon fiber. With these components, you can save a lot of weight.

So, one can put the power mode to "0" (not off which then the motor is decoupled and then it's just human drive train only. Then measure watts and calculate power output...if one got the power meter pedals, it would probably be more accurate and the just do the calculation automatically. But they run $500-$1500, so yipes

A good YT reviewer named Francis at EMTB Review is now using power meter pedals to do more objective measures between mid- and full-powered Emtbs. So we might be saying the same thing? Check it out and then just DM me if you want

Should not read anything with the motor off. Again it is reading the power used by the motor. Unless the motor acts like a generator...

Whoops. Looks you can hit cadence and watts modes in 0 power mode but no metering like you said. But it's does do the speed, trip etc. I just checked in the bike stand now.

Yesterday torture ride, this CEF50 and Bafang M820 ride flawlessly. Arrive at home with 16% battery left.

Head to head climbing with Shimano EP8 at 24% gradient 😍

Bafang M820 use level 4 of 5Shimano EP8 use trail level

Nice.

 

[spokémon]

Keep the ride and build reports coming people. Loving it! Helps with the torturous weight

 

[spokémon]

My understanding is that Bafang has 2x Apps. GO and GO+
GO seems useless, it is read only. GO+ is the one we want, but there's no evidence of it working.

The saddle and dropper are carbon fiber

Did you mean carbon seatpost? I never heard of carbon dropper post.
There's a significant weight difference between a carbon seatpost and a normal dropper post.

The shortest dropper is quite light as well. I don't use it on road, so for a 100mm dropper, the weight savings is quite significant.

when your height under 170 no problem

The pin is lighter than aluminum by 100-200g.

How many percent of the motor power did you use?

 

[temon10]

How many percent of the motor power did you use?

only using maximum level 4 with 70% motor power

 

[LAnton]

This is a very good indicator. Now I also wanted a 720W battery I'm tired of carrying a spare battery in my backpack

bike is light, but backpack heavy . Will make DIY 720W battery?

Yes. I think it's better to buy a ready-made battery. And melt the heavy body into wheels.

No he says Go app...
That is just the title of the thread.

He refers to the old Bafang Go App. This is working with my 245 Display as well. But no option to adjust levels etc..
Chili told me the Bafang documentation if faulty, and GO+ app omly works via IOT.
