I made a point of ordering the mountings and an empty case when I bought mine - I'm not going to use them though , PM me if you want to buy them from me at cost.Hi,
I've finally received the frame.
But it did not come with the battery docking and locking mechanism nor did come with the charging connector.
I've contacted Dengfu (Mia) and they say this is normal because I did not order the battery from them.
Is this normal? I did order the frame only with no battery, so I guess this is what happens when you do so. But still seem kinda stupid. Not to mention I asked them several times what accessories and parts would be included and all they said was headset and thruaxle. To be fair, they did change correspondant mid conversation. (Melody was replaced by Mia).
Anyone know where I can find this elsewhere?
Sorry, its not finished - I still need a battery
I just wasn't happy with the 48v/15AH options that I have with the empty battery case and frame mounting components I got from Dengfu. After a lot of reading, and nothing really hitting the spot, I decided to design my own solution.
This housing I've designed holds 56x 21700 cells, rather than 18650s - giving me 52v and a whopping 20Ah of capacity.
No modifications need to the frame, just remove the stock mounting bracket and locking mechanism, then bolt the thing in using the now empty holes.
It was a proper challenge getting the thing to fit the frame, and getting the number of cells I wanted in there. Lots of chin scratching required. Once it worked in CAD, I bashed together a scale mock-up using my hobby CNC machine. That fits perfectly.
It's being printed in PETG now. I'm super-excited, will keep you posted.....

The derailleur hanger attaches to the frame and forms part of the drop outs for the axle to secure in.I was going to order a E22 frame from an online seller. I noticed the derauiller hanger is part of the carbon fiber frame. Although I had yet to break the derauiller hangers on any of my MTB. Are all E22 frames built like that?
The cheap 9 spd didn't work out so well for me. It lasted twice aslong as the 12spd. Which was only 100kms.Just starting shopping for my build...any recommendations on what to buy or avoid?
Also if you are in Canada/USA feel free to dm me offers on parts you have...
I'll be buying new or nearly new takeoffs to save $$
Im thinking :
Fork: Fox 36 or yari or lyrik, or a Domain, zeb or Fox 38 if I can snag a good price
(I prefer more simple suspension with less adjustments than the pro level stuff, but will take top tier if a great deal comes up. I had a manitou Mattock pro on one bike and it had wayyy too many adjustments, really hated taking the time to dial it in)
Shock: Fox float X or X2 or RS Super deluxe, or Monarch Plus RC3 (not sure why the legacy monarch is still made but it seems decent)
Would consider DVO, Marzzocchi or Suntour comparable options too
Wheelset: 27.5+ 2.8" tires - not too picky on brands for wheels as most anything in a 35mm inner width is pretty tough stuff...
I like plus tires for the added cushion and traction, and since they are so unpopular I'm hoping to score a wheelset dirt cheap.
Drivetrain: cheap steel wide ratio 9-11 spd as so many report chewing through these parts. leaning towards shimano HG compatible hub so i can try a tough, wide ratio 9 spd as Bram recommended...or a cheap chinese 11 spd ( i have a LTwoo AX11 on my hardtail and it is really quite decent). Loved the SLX 11 speed setup i had on another bike - butter smooth shifting, but not spending the $$ if its just going to destroy it in short time.
Brakes: some cheap 4 piston setup sounds good enough - Meeko said the Sensah worked quite well...or good old reliable deore 4 piston..
I have a set of Ztto 4 piston brakes i was planning for another bike that might make their way onto this bike to give them a good test.
As you can tell, i am not at all interested in spending extra $$ to save weight. Brand wise, I Prefer shimano stuff over sram in general, and I find it fun experimenting with cheap chinese stuff from aliexpress/alibaba
All the other ancillary stuff i have lots of spares so no need to go into minor details...
What do you mean by being dangerous?I like GBK, I have ordered from them many times.
But their batteries were of poor quality.
They may have gotten better now, but I would thoroughly inspect any battery that comes from them.
Poor workmanship and dangerous!
The cheap 9 spd didn't work out so well for me. It lasted twice aslong as the 12spd. Which was only 100kms.
I have now put a kindernay vii internal gear hub on the bike.
I dont think it's the shifting that causes problems. All my teeth are worn and rolled over. There was no issue changing gears. The issue is the chain literally rides up and skips over the cassette when you use full power. When you see how the soft metal cassette teeth wear, and then fold over on the tips, it will make sense.thx, i'll just go with a cheap 11 spd and shift mindfully.....
Have a look on you tube for lithium battery fires. Once they go up, there is practically no putting them out. If they do burn, then they will destroy your bike in flames in the space of a few minutes.What do you mean by being dangerous?
... chain literally rides up and skips over the cassette when you use full power. When you see how the soft metal cassette teeth wear, and then fold over on the tips, it will make sense.
I did consider it. The price for the shifters and derailers is pretty reasonable. But the cassette is getting into xx1 territory. Plus none of the Aussie online retailers had stock when I was looking.Bram did you consider the Sram EX1 8 speed drivetrain? case hardened tool steel cassette, specially designed wider chain for ebike use...wide range 11-48t. Edit: just read a bikeradar review and the tester went through 3 chains and 1 cassette in 2500 kms...i think that still kinda sucks for a groupset that would cost me nearly $1000....
Ok i'm open to buying an internal geared hub if the price is reasonable..
I know about battery fire. I was wondering why you said GBK battery was dangerous.Have a look on you tube for lithium battery fires. Once they go up, there is practically no putting them out. If they do burn, then they will destroy your bike in flames in the space of a few minutes.

Definitely look into getting something steel, I have a 8 speed microshift acolyte groupset on my 45a bbshd and I'm over 1500 miles now and still everything is working great and the cassette shows little wear. The whole cassette is steel and is 12-46t which I find is more than enough for a ebike. Less gears = better imo as less shifting is needed. Plus the 8 speed is dirt cheap, whole thing costed me $85 after tax, I think a new cassette is under $30. I don't even run a shift sensor, didn't like how long it cut power, I just let off the throttle and shift immediately after and the left over momentum shifts the gear. I honestly don't get how bram is going through cassettes so fast, I do hope the internal geared hub fixes things for him.
I didn't. I haven't bought from them. I got my extra battery from Ding tai. They were alot cheaper than gbkI know about battery fire. I was wondering why you said GBK battery was dangerous.

As far as the battery cover it's not too small they all look like this.
For your information, these cases are called ShanShan SSE-103 and you can directly order replacement parts from them! Attached a file that gives an overview of the part numbers.
The manufacturer is indeed willing to share the 3D-model, if you sign an NDA and tell about your project. However Dengfu only used the case and doesn't share the intube part of E22 as 3D-model. I tried to get it for over a month. They are acting studpid, as they wouldn't understand what I'm requesting. I made my own model in case somebody is interested.

Even modeled the Smart BMS from JBD.

So I came off my bike and properly beat myself up, as a result I've been out of action, feeling sorry for myself and and only started printing yesterday.Sorry, its not finished - I still need a battery

That's what I made, but it kinda rough. Did it in F360 and you surely need to make it cleaner yourself. Misses a lot of details, especially the regarding the top lid.Am I correct in assuming that's what you made above? And I don't see a file for that model, would love to get my hands on it if that is the case
