You will need to work a lot with a file
Any other specific tool?
Could the cable, with the cloth tape on the outside, capillary water in ?
Well, thats because it’s the electric cable that connects to the DP E181 control. That wont get visible and the cloth will be under the headset after I install the handlebar to get the correct length
You will need to work a lot with a file
No, it just fits. I used it on mine.
That one will work fine also.
Apart from that a headset install tool if you’re changing the one that came and thats pretty much all its needed apart from allens and a torque wrench
Did you weight the battery? What was the weight?
Thanks, I think now I have everything else
Building a bike in the first since maaaaaany years is interesting

Any info for 165mm Alloy cranks lighter than Bafang original?

That is heavy.
I originally ordered the 410wh battery but had to settle for the 720wh because there is not even a estimated shipping date for the 410wh.
They shipped mine today, now waiting for the slow boat from China.
Same here... settled on the 720wh battery as I don't want to wait any longer. It's ready to go but heading out on a different slow boat next week to Canada. For now, all I have is this picture to stare at. At least she's looking good!

Hey Folks! Hells yaaaa!
Totally worth it! First ride was this morning. Built up a burly trail version 160f/165r for now. It's slightly heavier at 48+/- lbs with big tires, sealant, foam inserts, and pedals.
Waiting on my Zeb 38/180mm upgrades and then I'll install my lighter carbon wheelset, and lighter componentry. But should be 45 lbs soon!
I'm running the 720 Wh battery. And use the 245 color display.
I'm a heavy rider at 285+/- lbs. Did 20+ miles with 53% remaining. Today's trail was flatter choppy, sandy terrain with a few shorty techy climbs.
Stayed mostly in S-power mode (level 3 of 5) 70% of ride with bursts of S+ mode (level 4 of 5) at 20% and B/Boost-mode (5) at 10%.
Pedal drag exists, but it's low. I pedaled on zero mode for 1 mile in sandy, soft conditions...it's doable but not ideal of course.
Superburst "Rocky" doesn't exist for the 245 display. But it's unnecessary. I have a 181 display too, and I'll try that soon to see if it exists there.
Major Pro:
The Bafang-M820 -75Nm power is 3/4 of a full-powered motor. It's by far way stronger than the TQ50, Fauza60, RS60! It really feels more like 75-80 Nm! IMHO
Minor Con:
The motor whir is a mild tea kettle-like whistle in all modes. It doesn't both me at all!
The CEF50 rides well. And I was able to run my fatter RS SLDX MegNeg 210 x 55 for the bigger 165 mm travel. No binding at the pivot/rocker arm but I only did small pops and drops. So, 55 mm big stroke works for me at least! I'm looking forward to installing a more balanced 180 travel fork soon!
Overall, the maiden ride was impressive!
powerful motor
long range battery
big enduro travel 180f/165r
agile with a lighter rig-feel
Minor whistle-noise
Weak walk-mode (good only for shifting gears off the bike for an optimal setup)
Long term frame durability.
4.5
out of 5!!!
The sweet spot is achieved? Maybe...
Full-powered riders will still enjoy the slightly lower power for 10 lbs + savings of agility and range!
Analogue riders converting to an E-mtb will enjoy the power, but not suffer the from hefty weight of a full-powered rig.

I'm glad you finally got it!
Is that a 29 rear?

@TCFlowClyde 48lbs for what's on it is good. Are you running 27.5 ?
Did you try removing rear shock air and bottom out the travel to check for clearances?

Big mid fat 27.5 x 3.6 and plus 27.5 x 3.0 current.
Future is 27.5 X 3.0 and 27.5 x 2.8.

On fullbike with my component it weight 20kg and I just love it. Can do long range with 720Wh with lighter bike. Feels so good.

Today was the "hour of power" in decent heat!
97+F°
I went full boost-mode in rolling hills terrain with 65% flowy climb and a smooth, bermed downhill ripper 35%.
Just 53 minutes of 9.2 miles in all turbo to stress test the M820-75Nm performance tolerance during fairly hot conditions. I had 82% battery remaining.
I didn't notice any power drop-off!
Personally, I like to climb as an ex- analoger, so I've never been a huge fan of powering up switchbacks moto-style, especially in dealing with strong motor overrun and the drivetrain abuse potential.
The M820 had a little overrun in Boost mode, but it's minimal and can be used smoothly and predictably when climbing most tech. So, it yields a pedal-bike-feel still without being crazy like full-powered or wimpy like lower-to-mid powered motors. IMHO
Next ride is in the morning for cooler temps and on a fairly steep switchback-oriented mountain climb. This should really put it to the test for my typical riding terrain, and hopefully provide more testimonial feedback!

It looks like there maybe clearance for 29 x 2.4 rear tire? what do you think @TCFlowClyde ? 20mm gap from tire to seat-tube? So 210x55 shock with 29x2.4 rear tire?
Zhaosheng says, right on the spec page, it supports 29x2.6

I guess just try it. If not add, then a travel spacer to reduce the stroke?
My 27.5 + is taller than most 28.6" ish I'd guesstimate.

Those of us running old-timey derailleur cables, any worries about snagging the cable on a branch?
yes with 210x50 rear shock. I was wondering about 210x55
I think it was said somewhere 210x52.5 was doable with 29x2.6
