Able to get first ride in this weekend? excited to hear your opinions about the frame and motor!

I rode about 20 km. Yes, M560 is loud, but after these 20 km it became quieter. I think that after 200 km it will be even quieter, as it was in my m620. Only 2% of the battery was consumed (mixed mode econ/sport/boost).

About frame - I'm not happy with the wires running through headset. It depends on how the links are set up and when turning the handlebar left the derailleur shifts by itself and when turning right my dropper extends I need to improve the routing of these lines. Dengfu recommends that the speed sensor should be installed close to the disc to which the magnet is to be attached but I did it a different way. The battery moves and rattles, which can be heard when driving over small bumps - I stuck a piece of foam to the cover and there is silence.

Yeah, I'm planning on asking Dengfu to make holes in the frame near headset and use those instead of the headset cable routing. I guess you can get the headset cables to work if you are able to get everything perfectly in place but I wonder how long they will stay in place. Headset cable routing is terrible idea.. I hope they won't force it in mtbs in the future.

What's the difference between your magnet placement and dengfus? What made you do it that way instead of the recommended way? You found some pros/cons with these different placements?

Is the battery with the mounting points moving or the battery only? Or was it the battery cover which rattles against the battery? Definitely seems like something isn't like it's suppose to be. Why would they intentionally desing it so. Or maybe this is one of the problems with these early frames where they test things out.

Have you contacted Dengfu about the battery rattle problem? Really want to know what they say about it.

What's your setup with the spider, chainring and cranks? Did you get those with the motor or purchased separately? Is the chainline perfect with that spider? Haven't found information about what spider I need to get so it works with the frame. I'm hoping to find 160mm cranks for myself.

See photo. I don't have magnet and sensor that would fit such a solution.

I agree with this.

I think that's it.

Have you contacted Dengfu about the battery rattle problem?

I contacted Ben about hedset routing problem and I got the answer that they have improved this and he will send me new designed headset. This is terrible, look what condition are the cables in after 20 km...

What's your setup with the spider, chainring and cranks? Did you get those with the motor or purchased separately?

A get those with the motor. 38T and 11-50T rear. There's no ideal chainline, but nothing bad happens under heavy load.

Hello guys. Is there anyone who built or are building an E82 ebike can send me the scheme of the battery? I purchased only the empty case, since I already had the cells and BMS but I am having a hard time figuring out how to build the battery pack properly. It fits 80 18650 samsgung 3400mah cells inside the case and setup is 13s6p.

Did you find scheme of the battery?

@_gregor

Damn those cables look rough!

You should ask Dengfu about that battery rattling problem also!

 

[_gregor]

I've received the answer from Dengfu that they impoved headset elements.
Below are the new one.

No, sticking foam to cover eliminates rattling. I don't think there's any other way to do it after looking at the construction of the lock.

Maybe so but I think it's good idea to inform dengfu about it so future customers wont have to do diy fix and whine to dengfu. Dengfu can fix the problems themselfs

 

[Sayonara]

@_gregor I saw this in facebook. Is this the same problems as yours? Or was your noise coming from the battery cover?

It would be better if they brought back the normal wiring ports in the frame. So many movements and all for nothing.

I disagree with you ; if cable routing is done correctly, it's both aesthetically pleasing and functional. There are just constraints if one wants to service the bearings.

i disagree with you. With battery it have too lower space on ebike to allow easily cables/wiring translation, sometime when you fall with MTB the handlebar can make 360° and done too many constraint on cables.

If you have your bike serviced in a workshop, I don't see a problem either.
But I have to service the bike myself, in which case it will always be damaged cables and problems with removing the fork every 50 hours.
Not to mention what patdam described above.

Old vs new headset elements

Connecting battery with 1T4 cable gives you additional info on hmi

Hi, i want to buy an e82 but is it possible to put 750 or 840w battery on it ? 1000w is too heavy for my use (right now i have an e22 and i m really happy with the range)

I guess it can be done if you know batterys. Personally I think I'm going with LightCarbon LCE971 frame. It has 720Wh battery.

 

[Stubbs]

Hi All, I've just read this thread AFTER buying my E82, I'll keep you guys updated. One question regarding painting the frame, do I need to rub down the Matt black finish on the bike before I spray?

 

[xtraman122]

I wish these guys had just released a size L quicker, I ended up going with a LightCarbon mostly due to that. I prefer the look of the E82 but need a bike that fits me.

 

[Alessio77]

I've been told by DengFu yesterday, that Large size production will start in July, with first frames available at the end of the month.
Haven't asked about frame/motor/battery combos yet, nor if a frame cable routing will be available (I'd prefer this way).
By the way, not sure at the moment if I'll go with this heavy enduro oriented build (180F/170R travel) or a LightCarbon with M820...This will be my first ebike and I already have carbon wheelset for a trail oriented build, but trails around me are a bit nasty and full of volcanic rocks, where I sometime struggle with my 130mm acoustic bike.
Other than that, I have no idea about how strong is a M820 on a 18/19kg bike...

 

[Mia Dengfu]

NO, E82 is with different battery case from E10

I went with Lightcarbon LCE971 with m560. Bought 160mm Fox 36 performance elite for it and RockShox Super Deluxe Ultimate.

 

[Alessio77]

More chat with DengFu today and I discovered that this frame also accept a 230x65mm rear shock, thus reaching 185 mm of travel as per attached geo chart; interesting if building it as a big enduro/ freeride bike when paired to a 180mm fork IMHO.
Another important aspect is that they're now providing E82 frames with a conventional internal cable routing instead of the ICR.

I'd like to hear your feedback about that powerful motor.
If LCE971 suspension kinematics is well thought out, you'll enjoy it; I've had Intense VPP frames and they were playful !

From what I have heard from others they really like the VPP system. The shock mounting style in the dengfu e82 is more suitable for trail bikes.

I'll make a build thread here once I get my bike done!

Only shock bushings missing... lost in mail sadly..

Nice build! That Eddy Current is a 27,5"x2,6" or 2,8" ?
