They have a nice ebike light quite cheap, but it only works with a converter box… not on the dediacted light cablesin france the best products are from K-Lamp France
Not sure the box will fit anywhere in the bike

ask it, it build all himself and it have great knowledge on this subject and he like to share it. He have showed me one time those used the the trail running mans and we can see as if we were in full day, impressiveThey have a nice ebike light quite cheap, but it only works with a converter box… not on the dediacted light cables

What bike are you building up? LCE930 or CEF50?

Cool! Looking forward to your video.LCE930
Niiice!
Yes noticed today on my 1st rideHey guys, do you notice a motor rattle, when coasting on rough ground? I did the first run today, without a battery and there was quite an annoying rattling sound present. It was quite pronounced. I would say it is very similar to EP8 rattling noise (based on what I read and saw on youtube). It sounds like a loose ball bearing is hitting something. it is not chain slap and also nothing in my frame rattling. It feels like an empty hollow downtube amplifies the noise and makes it even more annoying.
Any similar experiences?
Hey,Guys, here is the noise I have when the motor engages and disengage.
Do you have this?
I've noticed the same noise. At first I thought I have some cables slapping around in the frame, but it's really when the motor engages. Sounds l like marbles spinning inside the hollow frame . Also have the clunk over bumpy terrain. I wonder if this is just par for the course with the M820?Hey,
I noticed, that I have verry similar noise. To me, it looks like it is coming from the same freehub/ratchet, that is causing the motor to rattle, when free-coasting over rough terrain. Does your motor also rattle?
Please can you mention (those who have noise and those haven't) your firmware references ?I've noticed the same noise.

Also have the clunk over bumpy terrain. I wonder if this is just par for the course with the M820?
Yes, exactly like few loose marbles or ball bearingsI've noticed the same noise. At first I thought I have some cables slapping around in the frame, but it's really when the motor engages.

In boost you get around 540WDoes anyone have some actual info on peak watts on this motor? Building the battery soon and I have 13S3P configuration, with INR21700-M50LT cells. They can manage 14,4A, but in lower temperatures only 2,4A!
- -20 … +10°C: 2400 mA (2,4 A)
- +10 … +25°C: 14400 mA (14,4 A)
- +25 … +55°C: 7200 mA (7,2 A)
So that would make 2,4A*3*48V = 345,6W
Is this enough I wonder? Maybe I just need to take it easy in the winter..
Ok, thanks!In boost you get around 540W
Also, why are multiplicating per 3?
Yes my bad, I thought you were taking in account your serial connection amp rating and not your cellsOk, thanks!
Multiply by three because I have 3 cells in parallell, so three times the current.
Its going to be tight when you initially use the bike but do remember as the batteries are begun to be used, they do generate some heat and will soon be up to a useable working temperature.Does anyone have some actual info on peak watts on this motor?

I will store/charge it in warm garage, so initially it will be ok, maybe just better to skip the really cold days.Its going to be tight when you initially use the bike but do remember as the batteries are begun to be used, they do generate some heat and will soon be up to a useable working temperature.
From experience when a battery is at these limits, it maybe better to choose a different type, remember that a manufacturer will test a battery in ideal conditions. Our use in an EBike is anything but.
