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

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

Thanks, I think now I have everything else :)
Building a bike in the first since maaaaaany years is interesting 😀

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.

PXL_20230602_172354361.jpg


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.

PXL_20230602_200417290.jpg


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.

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.

Glad You're happy too.
 
Hea you guys that already have bikes running please feel free to post glowing reports about how happy you are with the bikes. The rest of us will not get bored!
 
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?

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.

Just ordered my CEF50 frame, 720W battery and m820 motor. Anyone have a build spec they would like to share with links for parts. New to start collecting the components. Shooting for ~40lbs build.

Thanks.......dp
