KaroKonig cracked his M820 open and decided to add some extra lube generously applied in attempt to reduce the motor whir sound. He noted that it was probably under greased by the Bafang factory. I found this to be the case in my M600 when I re-lubed it with John Deere corn head grease last year. Seemed to work great!
I was able to over-stroke the CEF50 at bit. I went with a 180 fork and 210x55 rear air shock (165+/-). So far so good @ month 6. Lemon10, I believe also has been able to use a 55 mm stroke as well. So, more proven travel if that's what you want. (Although, I suspect there's a few LCE930 owners that have been able to increase travel too.
).
)....saves some money there. Consequently, motor/battery issues are covered through SZZS support too. So, there's a major convenience for good support for all, not just the frame (which LC-Jim does support well. I have the full-powered LCES04 frame.
).
still the same, power drop when battery reach 18-19%Cool. Test it out for below 20%.
10-12% power down would be nice.
Bafang always super conservative toward saving the battery...My M600 is a 27% threshold.
55 mm seems to work. I just pulled apart my rear linkage to paint them. No binding (i.e., chipping paint or scoring) was apparent. My rear shock has no travel reducers, even for the MegNeg upgrade.
52,5 will be safe and fit.
I couldn’t remember was that 27.5 or 29 you were on?But 55 works too. No issues for 7 months.
27.5 x 3.0 front/27.5 x 2.8 rear. So, sits close to a 29er (plus size 28.7" tall).
Agreed. I run a 55mn stroke. No issues with a 29x2.3 Maxxis DHR2.But 55 works too. No issues for 7 months.
Do you recall how he measured it? I wonder if others who know how to measure travel path can reach a consensus.
that's great! I don't think that would fit in the LCE930, but that's quite light for a factory battery
My suspension chap has built a harness-like contraption which when the rear wheel is removed from the drop-outs, a marker like device is installed onto the axle once inserted back into the drop-outs.

Another advantage of the CEF50 is that the drive unit and battery (including wiring) are already correct and set up. Building a DIY battery does take a knowledgeable skill-set especially!
Also, overall the CEF50 is selling the M820 motor and battery at wholesale (at least for now
Oh yeah! Small upgrade. The speed sensor has been upgraded to be hidden more discreetly for a rotor magnet vs. old-school spoke magnet. KaroKonig was able to do a work-around for his LCE930 to achieve a rotor magnet set up but he's a very skilled DIY builder doing outstanding upgrades.
Yes, I noticed these details too, like the magnet that I like the rotor one better. but what about the weight? I would like to make the lightest e-mtb light possible with a budget that is not very high. I made a table in Excel and indicatively (for the cef50, if the weight of the frame is right, 2500g in size M) I would get a bike that weighs 17.5 kg.I was able to over-stroke the CEF50 at bit.

Both are great bikes...can't go wrong with either. 50/50.
thanks again for the reply, I calculated a 36 Fox or Ohlins fork. given my weight I should have problems. I currently use a normal xc made in china mtb with a 32 fork with 100mm travel and I have no problems.Both are great bikes...can't go wrong with either. 50/50.
I wanted the big battery, big travel, just big Enduro, as light as possible. I'm at 45.5-6 lbs+/- with beefy tires and a Zeb38 (so dry weight). Most don't want a heavy Enduro.
Others feel free to chime in with lighter 36 fork builds... Good hunting

I noticed the wheel magnet then saw Karo's thread.

As mentioned here before, I think you will be happy with either. I chose the LCE930, but I think the CEF50 is just as good.
Related answer. Leverage ratio for 210x50 spec is taken from the kinematics direct from published leverage curves by our SZZS engineer. Found in the SZZS website and early (p.3 or 4?) in this long a$$ thread.
50 mm stroke x 3 = 150 mm travel52.5 mm stroke x 3 = 157.5 mm travel55 mm stroke x 3 = 165 mm travel
I was faced with the same decision and am about to order a CEF50.
Thanks a lot for the answer. well for the battery you can get up to 720wh as shown by you, yes of course 500 g you don't feel it but it was out of personal ambition to have managed with the little budget to make a very light bike that is close to bikes like Fantic rampage, scott lumen etc. ..
Correct mate, page 2 of this thread. Leverage ratio starts at 3.7 and ends at 2.5. Average is 3.1, so for a rough calculation its ok to calculate with leverage ratio 3.Related answer. Leverage ratio for 210x50 spec is taken from the kinematics direct from published leverage curves by our SZZS engineer. Found in the SZZS website and early (p.3 or 4?) in this long a$$ thread.
Thaeber our resident mechanical engineer determined it was 3:1 leverage ratio. Or Spec travel 150 mm/ 50 mm stroke= 3. Correct any errors Thaeber.
I just take it at face value and feel confident in our SZZS engineer. I'm staying with the numbers...I trust the science.
thanks, I don't know about the weight, because LC declares 2750g unpainted in size M and 2400/2500gò for cef50. I don't know about the price because it keeps changing for me and LC hasn't given me a definitive price yet. I like the position of the magnet, I also fit the one of the cef50, in fact I asked Jim from LC for explanations and he explained to me that it is a question of comfort for the magnet on the rotor with the high temperatures generated by braking it tends to demagnetize, I don't know if it is true, of course there is a grain of truth. a magnet loses strength in the heat. I found the contact with Jim and with the cef50 sellers equally good, I have nothing to say to the contrary.I was faced with the same decision and am about to order a CEF50.
The following factors convinced me:
Price (also price of the paintwork)
Weight
Magnet position
Complete package (frame, motor, battery)
contact
"Standard" cable routing possible on request
Yes, the LCE930 looks better, but the overall package makes me lean towards the CEF50.
All the components are already at home, only the frame, motor and battery are still missing
All matte blue (forks) looking good.
Good first report.
