M820 Bafang - LIGHTCARBON LCE930 Frame (lightweight)

[Chickon1]

I just put a coil on and it feels awesome.. it probably needs a progressive spring to help with bottom out.. I have a huge stopper on mine

This thing is going to be sweet!

That’s beautiful and I love the color! I know you said it was a custom color so I understand if you’d rather not, but I would be very interested in the color code if you don’t mind.

What controller/display is everyone using? Any pros/cons to consider? Thanks!

Team! I need help!
I’ve installed a t type gx on my lce930, and in 12th speed, it rubs against the rear pivot:

@Rob Rides EMTB you don’t notice any issue on your installation ?

 

[Chickon1]

I would check make sure the cassette is seated properly.. no spacers behind it. I didn't have a problem with the UDH and a 12 sp cassette so it seems correct on the chainstay.

It looks like it’s properly installed, right torque, no spacer of course

Please send me some photos via email and I'll see if I can fix this problem with less bulging bolts. [email protected]

This looks like cassette is too far out. From that angle I can see maybe 1 mm of the endcap between cassette and frame.

I’ve checked and the cassette is fully engaged… Jim is sending me a new bolt to solve the issue and I will try to change the chainring maybe to help as well

But it looks like the chain is touching the derraileur as well. It could also be freehub that is not all the way in.

You are totally right, the picture got me worried so I had to check this!
It looks like it's touching the derailleur but I guess it is the angle of the photo that causes that. In reality, the chain is clearly above the derailleur and there is a security margin
I will wait for the new bolts and see how this goes.

Also any of you already used a Bosch direct mount chainring on a M820 ? I thought this was compatible but @patdam makes me doubt

In reality i don't know because i use spider. For the crank arms,It's ISIS standard and i know that bosch fit (i use it). But for plate i never read that is the same teeths than bosch ?

Battery life tests.. Mostly flat with some step short climbs.
I road mostly on stock level 2 for 14 miles. - used about 15% of the battery.
Did the same on mostly stock level 5 and used about 40% battery. I'm 235lbs and that is pretty impressive..

I'm probably gonna build a 200wh battery to reduce weight.. I generally never ride more than 10-15 miles.

The motor and battery removal is about the worst of any ebike I've worked on mostly due to the cable routing.

@JimLee-Lightcarbon please get rid of the headset cable routing.. it is horrible.

That's my only complaints. Awesome bike!

Nice range, usually for 23km ride with 750m d+ I use 75% in S+ mode with a bit of boost.

Hi everyone,first post on here!my frame just arrived yesterday, looks phenomenal! Just waiting on battery and motor now!

Quick question for those who have built before, can anyone recommend chain rings that can be used on the motor,preferably looking at installing a Hope chainring as most of the components I will be putting on it are Hope parts. Any advice warmly welcomed,looking forward to the build!

you will receive a spider or direct mount chainring with your motor ?

I will do,was just looking to put a Hope chain ring on instead if it's possible

I received a direct mount.. anyone have the spider part number or link?

I also have a direct mount 34t... I know somewhere in these forums a link was shared for a proper spider on Aliexpress but I can't find it right now

Just swap left pivot bolt with right one, of them is more flat

Thanks! I need to try this !

What am is missing here?!.. I have been looking at the geometry numbers and can't get the chainstay length to match with the other numbers!
It's been a while since i did trigonometry even it was part of my eductation..
I have been comparing chainstay, BB drop, wheelbase and Front/center. Too me it looks like at least one number can not be correct!
I hope it's the chainstay ;-)
Please enlighten me if I am doing something wrong in the calculations

Front center is probably wrong. It should be with 150mm fork but still offset can change and I have seen some strange A2C measurements in geometry charts.

On my bike, with 170mm fork and 51mm offset, I get 1280mm wheelbase, 457mm chainstay measured.

The relative long wheelbase is a good thing, very stable at speed.

Thanks for input. I am quite sure stability is good, but I guess it will be with the trade-off, that manualling and flicking the back end will require a lot more effort. There is not a lot of other bikes in this category that long. More like 440-450

hello

I have a question, what money do you carry on your bicycles?
I currently put one with 32 teeth.
Would this bike work better with a 34 tooth or 36 tooth?
greetings
