Hello.
I'm trying to find a higher-capacity battery for this ebike (I currently have a 410w Bafang battery).
I've located Agazzicini Bikes, which has higher-capacity batteries for this ebike model.
They're asking €710 for a 645w battery, plus charger and shipping.
As you can see, this price is either right or too high. What I'm told is that the BMS might not be entirely accurate, as it wouldn't display the correct battery. Regards.

Selling my LCE930 medium frame, complete bike. All new parts, except the fox 36 fork and only tested in driveway. TRP brakes, SRAM GX 12 drivetrain,PNW 150mm dropper. Picked up a different ebike waiting for parts on this bike, so need to sell. Has the newest headset from lightcarbon for cable routing. $4000

Hi all,
Today, during the ride, I received ERROR 21 and motor refused to work. I checked, and it should be a problem with a speed sensor. It looks like the wires in the cable got damaged. If I wiggle the wire that goes from the chain stay to the frame, it sometimes work a bit, especially if I am not on a bike. But If I sit on a bike it stops working. This is why it looks like, the bending on the wire on that point caused the failure. I already ordered new speed sensor from AliExpress, but it will take at least 2-3 weeks for the sensor to arrive.

To me, the path of the cable looks quite unnatural at that point. When suspension compresses, it essentially pulls the cable from behind the motor cover.

Anybody else had issue like this? What would be the best way to prevent another failure?

Would anyone like my HukTek custom titanium motor bolts I had made for the lce930? I'm parting out my bike.

These save 100g vs the standard steel bolts. Plus they're just cool!

$150 USD shipped in the United States. I'll ship overseas if you pay postage.

Hello.
The same thing happened to me.
When the suspension is compressed, the cable stretches and comes loose from the motor connector.
I solved it by making the engine guard entry hole slightly larger, so the cable would have more travel.
I also mentioned this to LightCarbon, so they would take it into account and provide a cable a few centimeters longer.
Regards.

Hello.
Could someone tell me where I can get the motor protector for this ebike model?
Regards.

 

[Radolf]

You can buy from JIM, you can make it yourself, you can also print it on a 3D printer - the cover design is on this page.

Hey all, I went looking for the more advanced Go app to get at the power settings. Installed the app. It offered an over the air update for the bike, seemed like a no brainer....did that. It now is giving an error and will not run. App connects and shows all the connected info but it throws this error 07 Bus over voltage.....did I install an incompatible firmware or something?

Do I need to get hands on the BESST tool? is there an over the air way to roll back the firmware?

Hi
I had a similar problem, I thought something had gone wrong with the controller but couldn’t find wrong, I flashed over the original settings using my K1 flash tool and problem solved.

Don't have that tool.....is a basic USB UART cable suitable?

 

[Radolf]

Write what engine software you currently have installed and what battery you have (what voltage). The cable you indicated is incorrect, you will need Besst Tool which works on the CAN bus.

yes I figured that out, Can bus cable needed. Battery and motor are 43V.

 

[Radolf]

You have uploaded firmware for a battery with a nominal voltage of 36V, but your battery has a nominal voltage of 43V - this will not work. You need to find someone from Beest Tool to upload firmware for a 43V battery.
