When I message them on Alibaba it says its going to Jean Wang other people are messaging Linda, am I in the wrong place?

I've been in touch with Jean since the beginning. Thanks to Jean, we were the first to learn about the CEF50 frameI've been dealing with Jean Wang from the start. She's quite responsive
Linda's engineering team says it should. See above in recent thread.
But first thing I'll do is fit my MegNeg out of the box when frame arrives. My backup was going to be the Fox X2...so that should show you my confidence level.
Here's the Transition Relay. It has a similar shock set up. See how similar it's the CEF50'S? The rocker arm should push the rear shock out forward and down in a compression arc, clearing any friction points away from the seatpost. It looks to be an optical illusion.I am looking at used Fox x2 210 x 55 rear shock.
Will that fit?
It's the best one in my opinion.I got my quote today.
They are quoting me this display

Others please chime in which remote/display you're getting.
The linkage is pretty different between the two. I imagine the leverage curve would be substantially different as well.Here's the Transition Relay. It has a similar shock set up.

If not Relay testers/reviewers like RobRides and others would have definitely said something. So, I think that boosts my confidence level a bit, and when I finally get the chance to toss on my fatter MegNeg air can as soon as my frame arrives... hopefully!

I have the previous C242 model black & white. It didn't have a power meter on it...just the basics. I believe the C245 is the same...just color and smaller and actually fits both 35 and 31.8 hb clamp size.This is the one they quoted me also DP C245.CAN. Does it measure rider and motor output and/or matched wattage?
We're talking just about clearance of the aircan during compression from the actual seat tube near the mount...not spring rates or leverage curves. It looks like there might have been contact but it's a visual distortion. It should clear the front part of the seat tube.The linkage is pretty different between the two. I imagine the leverage curve would be substantially different as well.
PayPal for sure but via direct Alibaba paylink...I think...it was 3 months ago.How did you pay?
Did you use Paypal?
Here's my request to Linda about buying a 2 yrs extended warranty option.DIY Frame warranty: elephant-in-the-room? Mentioned here in recent previous threads is the CEF50'S light-weight frame. And the 3-year frame warranty. Most of us buying direct consumer or DIY carbon builds acknowledge that quality control lacks, support lacks, and warranty lacks compared to the big brands.
Consider these arguments. Many and most high density carbon frames in the world are fabricated in mainland China, and the big brands use them! Orbea and Kelly appear to make theirs in their home countries, as well as a few obscure others.
What stands out is little to no field-testing and quality control...the DIY builds take a certain amount of courage to be among the first to spend precious resources on an untested product.
As others with previous DIY build can attest to, customer support really has improved after purchasing their products with some of the better-known Chinese frame manufacturers like DengFu and Light Carbon. RobRides really held the DengFu E10 frame accountable along with the Bafang m500 motor. He should be able to do the same the M820 LCE930 light weight build, as well.
Sure, I wish the frames could be lifetime warranty like Forestal, Transition, and Orbea, just to name a few. Their field-testing is unparalleled. Probably why forums like this tend to help bridge the DIY communication gap better. Very few legit Bafang YouTube reviewers out there unfortunately.
While the CEF50'S warranty is only 3 years, sometimes an extended warranty can be purchased. I'll ask to see if they might consider an extra 2-year extension upgrade for an nominal additional fee. I encourage others to inquire if interested. The more that inquire, the higher the demand, the more likely it will happen. A 5-year warranty has nicer degree of confidence.
Frame weight comparisons. All have a fully integrated downtube battery that requires a burdensome motor drop technique. Sure it's not complex, but it's not quick either. I can drop my motor in/out in 30-45 mins. I don't do it often, so it could be faster, but I'm no race mechanic....so.
The big advantage of no large battery cut outs is both strength and loss of weight. Plus, less hardware mounting weight for a latch and cradle system found in the Relay (which looks super convenient and a great engineering feat). Orbea's Wild M-LTD race build claims a 900g/1.94 kb frame weight savings while calculating a 51% gain in overall stiffness frame integrity. The Wild in large with 38 forks and exo casing tires comes in at a mind-bending 46.5 lb/21.09 kg for a full-powered 85Nm motor...just WOW! Unfortunately, frame weight is not listed.
The Forestal Siryon in the light-weight, mid-powered category where the large frame comes in at a claimed +/-5.29lb/2.4 kg. The travel is a bigger 170f/170r and is supported by this frame weight.
The Transition Relay frame weight isn't listed either, but in the heavy PNW build, it's estimated to be 44.5 lb/20.19+/- with large 38 fork/exo casing tires. The frame supports 170f/160r rear travel. Damn close to the CEF50'S specs of 170f/150r travel and their frame weight is supported.
The CEF50's frame in large is 5.32 lb./2.415 kg (scale weighing posted in this thread previously). Structural integrity is unknown, and frankly is the risk-to-reward tradeoff or relevant metaphor: the big, obvious issue that is politely not discussed, or simply the ignored elephant in the room.
Theoretically, after the 3-yr warranty expires, a new frame replacement would be another $800 USD. To get to the current cost of the lowest carbon build cost of the Siryon is $9,000 USD, you could spend 10 + years buying a new CEF50 frame replacement every year! So for me, the risk is mitigated, plus I get to outfit the build they way I want as several of my pricer components carry over from the past DIY build. (My carbon wheelset, my Transfer dropper, GX-axs drivetrain, and XT- brakes.)
Anyway, don't let the doubters and haters diminish your courage on purchasing the first batch of the CEF50 frames. I'm not! Besides, the doubt and hate is often based on ignorance (commonly willful), fear of the unknown, and frankly, just no-to-low due diligence. And like-like (as close to as possible) comparisons are demonstrated here to give more informed contrasts, given the limited information.
Nutshell: I believe it's low risk (no field-testing) to a very high reward (cost savings performance). You'll have to make up your own mind however.
M600 walk mode was weak ass too...almost useless except to change a gear while standing in place.I hope M820 walk mode have more power than M510. All M series i have tested walk mode is too slow compared to Shimano or Bosch.
right M600/M500/M510 walk mode too weak and useless. And we dont have option to change via Besst tool either. Proper walk made have advantage when uphill couldn't pedal the bike.M600 walk mode was weak ass too...almost useless except to change a gear while standing in place.
But my bigger M620 motor is almost the opposite...too strong!
M500 walk mode works nice (with firmware CRX10NC4813i142015.8-28-2230-20210805).right M600/M500/M510 walk mode too weak and useless. And we dont have option to change via Besst tool either. Proper walk made have advantage when uphill couldn't pedal the bike.
