Dengfu E82 - M560 750w Build (Was: LightCarbon LCE971)

[Sayonara]

i just want to say,

i have seen 3 cracked lc emtb frames that i build it the last 3 years. Yes Jim is easier to deal with compared to dengfu but i never seen any cracked dengfu emtb frames tho.. i did get help with warranty in all cases

for the broken bearing, i used a special bearing puller before to pull out bearings from carbon. it can be done smoothly id you have to right tools

if you dont have the tools maybe you can just pop off the bearing cover and try to add some grease. i have seen both lc / dengfu frames without any grease in their suspension bearings

they both use low quality bearings in my eyes

I haven't heard or seen any cracked frames from LC only the cracked test frame we saw in this thread earlier. Where and how did your frames crack?

Were those low quality bearings from LC on older frames or these newer ones also? The bearings they currently send with the frames are high quality.

It’s fair to say I haven’t actually had my hands on an LC frame yet, so I shouldn’t talk them up too much, but based on others experiences and the number of quality bikes they seem to OEM for (Their painting album had lots of branded bikes in there and I have a local reseller who sells a bike based on the LCE930 that is well regarded), it seems they do make good frames.

The durability concern is the thing that kept me from using the LCE971, I personally just think there’s some fundamental flaw in the design and that’s what scared me away. I also wasn’t the biggest fan of the look of it with the squashed looking rear triangle that’s part of the VPP design, but that’s just me. I really hope they come out with a new M560 based AM/light enduro frame with somewhere in the 150-170 range of travel, I’d scoop it up in a heartbeat. Or if DJI ever ends up selling their power train separate I’d kill to be able to build an Avinox based bike myself.

Their website says they use Endurance Max bearings so that’s what I was going by, I thought those were quality bearings used by many, but again, I haven’t experienced it myself yet so I can’t say for sure.

Did a quick ride yesterday and again today between work meetings, I have about 14 miles on the bike now and love it. Such a massive upgrade from my alloy hardtail with 100mm of travel

The M560 has silly amounts of power, I've found it to be perfect on Trail mode (Level 2/5) where it peaks at 500W output. I've tried quickly testing out Boost (5/5) and it shoots right up to 1200W if you push it and feels absolutely crazy; I was able to accelerate, up a hill, to 20mph. Needless to say Trail feels perfect to me for regular riding, and I could see Eco even being plenty for a lighter rider or someone wanting even more of a workout (That seems to peak around 250W).

The GX Transmission is a dream too, after one small adjustment after figuring out what they wanted you to do in one of the setup steps, it "just works". Shifting is flawless through all 12 gears without hesitation and it seems to take a beating under power without issue at all, truly an awesome setup.

My one outstanding issue is still getting the Dengfu battery to work. I ripped the motor out last night hoping to find a loose connection for the battery CAN wire, but no luck. Wiggled all the wires, tried reseating things, it just won't power on. I think the battery itself is fine, I get 44V between the first two pins which I assume means the battery has some juice. I don't know if something is messed up in the BMS or my wiring harness is bad. I ordered 2 more 1T4 cables from Aliexpress this morning that will probably take 2 weeks to get here and then suck to install, but if that doesn't do it I'm not sure what the issue might be.
