yes 720Wh, so also can't supply bafang 36v battery for now. All I can do just waiting.720whr battery?

Ok now that we are all stuck waiting...
I have never built an emtb, a number of chinese MTB and Fatbikes but not ebike.
Are there any tips and tricks to running the cables and mounting the motor? Gotta do this in the right order or have to tear it all apart to do it again? Battery connectors etc. Padding the cables so they don't rattle?
Let's transfer some knowledge here!
Take the additional 3 lbs and go big! Pretty shure You regret the decision for the smaller battery, if no range extender is available.View attachment 109145
Linda, says you have to choose between the m820 motor, 43V 410wh battery and 36V 720wh.
The 43V 410wh battery is marked for eMTB and the 36V 360wh (36V 720wh) battery is marked for eRoad on the Bafang home page.
What should I choose?
It totally depends on how you ride. If you ride a 12 mile single every day then there is no reason to carry the extra weight. if you ride all day adventures to the top of a 5,000ft mountain then you probably want the 720whr. If you ride 12 miles singletrack and once in a while do a big adventure then you probably what a 410whr and an extender for the times you go farther. There is no right answer it just depends on how you ride.
All the M820 ffamily can be used for road or mtb. Both the 360whr 36v and the 410whr 43v can be used for mtb. The 36v 360whr mtb battery is FT100.b360.c.
It all depends on elevation. Moving against gravity takes the most energy. I don't think you could do 35 miles with 2000 elevation change on a 410whr but that is a guess from my experience with my Orbea Rise with 540whr.I agree with this except I already do 17 miles and 2000' in very chunky terrain on my pedal bike.
Seems the 410 would do 30-35 miles like it was nothing.
Or spend 60% less for the same travel and same high-end componentry, and yes give up some turbo power. Hence, the M820-75Nm, 720Wh battery! BTW, true the Orbea Wild M-LTD 625 Wh 85 NM in large w/38 forks is claimed 36.5 lbs, but for $11,999 USD, AND availability, according to several local Orbea dealers is well very "limited" worldwide!Good choice, if you’re going to go 750Wh battery you may as well build a full fat and be done with.

So, you're comparing apples to oranges...
Also the WIld does not give a kicker boost over the 85nm. The M820 will pop you up to 95nm when you need it.Clarification: I did err here on travel, weight, and battery capacity. So, after my weigh-ins of my all my compemlnentry...I posted my updated dry-weight last Friday, to be 45.6 lbs I believe.
Compared to the Orbea Wild LTD:
-I have 180/Zeb 38 fork travel vs. LTD's 170 = +10 mm
- I get 165+ rear vs. 160 "= +5 mm
- I get greater battery capacity 720 v. 625 = +95 Wh.
- I get 220 mm v. 203 mm rotors = + 17 mm
- I get the heavier casing tires (Maxxis Exo)
- I have an overbuilt (heavier) carbon Onxy hub 36 spoke wheel.
- Fully DIY serviceable M820 with readily available parts and no warranty penality for cracking open the drive unit to do basic service maintenance.
- CEF50 is 75Nm v. LTD 85Nm = -10 Nm
All of this more is "Enduro" than the enduro-trail Wild LTD. Again, not bragging, but with discounted high-end componentry, I still save about a pound, and should spend a total of $5.5k USD.
Conclusion; Sure, the critical minus (-) is 10 less Nms. However, there are a lot of pluses (+) on this build over the Wild LTD. Jus' say'n: different strokes for different folks...and I certainly don't have much disposable income.
So win/win for me on my M820-75Nm, 720 Wh 180/165, mid-powered, truly light-duty E-enduro build.
Hoping it works as advertised...please Bafang no frustrating 4-sec delayed ramp-up (a la Fazua60). However, I do luv Shuttle SL and probably the Relay if I could ride one, but not for me, and not at that price?Also the WIld does not give a kicker boost over the 85nm. The M820 will pop you up to 95nm when you need it.

You know everyone's build is going to be different. So many of the parts are arbitrary choices. Many of our parts will be based on the deals we could find at the moment. The fun for most of us is finding/hunting for the parts, looking for deals and making something ourselves. When I got my Orbea Rise I stripped ALL the parts off and built it up myself from scratch with the parts I wanted.I want to build one of these but I Don't have any experience a building a bike, let alone electric mtb.
I currently ride a approximately 18 year old Stumpjumper full suspension. I think I want a light weight and I have a fairly tight budget.
Is this possible?
Does anyone have a component list, and where is the best place to buy everything?
Stephen.
I found Rockshox Deluxe Select rear shocks, in the right size, for $143 and I choose a X-Fusion Slider fork at 1790g and $350. So it is possible to meet your budget if you work and search well.You know everyone's build is going to be different. So many of the parts are arbitrary choices.

So it can be very rewarding. But I think you need to choose this path because you want to learn about building a bike not for saving money or you may be very unhappy. If you had to pay someone to build it for you, you are not going to save a lot of money.
Also remember we are all gamblers here. This is a new motor and a previously unknown, in the US, frame supplier. But the price is very good if it all works out.
To quote Churchill, "Play the game for more than you can afford to lose... only then will you learn the game."
I built my E10 M600 with 810Wh battery for less than £ 1500, so your bike is more than expensive in comparison, but thats just stats. Sorry you're not exactly quoting like for like. One is a DIY component build, the other a branded bike with full two year warranty, take it back to the dealer when there's a problem. Sorry my view of a lightweight needs to be 18kgs to make the lightweight worth while ( you can build sub 22kgs FF's without too much trouble ) and that means probably only a 34mm 140 - 150mm suspension ( maybe only front suspension dare I say it ) with probably only 50Nm of motor torque and 450Wh battery, to be used mainly on trail riding and less demanding terrain.Or spend 60% less for the same travel and same high-end componentry, and yes give up some turbo power.

So, you're comparing apples to oranges...
Easy.I need to get a list and start adding up.
Yes, that certainly was a helpful, well-thought out critical-analysis. If you had the receipts as the kids say (actual facts) you would have valid disruptive, contrarian input....rather than just simple trolling. I don't need luck, I've presented facts thus far.I built my E10 M600 with 810Wh battery for less than £ 1500, so your bike is more than expensive in comparison, but thats just stats.

I'm wishing you well in what you are doing however, its an interesting experiment and I wish you luck as I do wonder whether a lot of the current crop of carbon frames are over engineered, but please if your frame doesn't survive, don't blame the manufacturer as you seriously have upped the weight and terrain from what it was designed for. Good luck and keep us informed on the outcome.
Unless you bought your frame, motor and battery used. You are not going to get those prices from Dengfu and then that does not include any other parts. Unless you had all the parts anyway and then it is not accurate for anyone else.I built my E10 M600 with 810Wh battery for less than £ 1500, so your bike is more than expensive in comparison, but thats just stats.

I assume that it's all done. Which probably means add another 1-2 weeks for mine to ship?So are you just waiting for the battery? Is your frame done?
Linda said waiting the 720Wh battery finished.Could be waiting for the motor I suppose.
