What's the consensus best DIY frame right now?

[Nobrks]

Встречайте, новый, легкий карбоновый велосипед с мотором м820. Раму и мотор я получу в конце января. По моим расчетам вес нового велосипеда будет от 16500-18000 гр. В зависимости от уровня комплектующих.

Hmmm..but they are referring to a Bafang Battery BT F014 which is speced on Bafang Workbook, and a completely unknown Battery type ZS BT 740. No info on that available…

Bafang Battery BT F014 produced only 43V. The ZS BT 740 can be manufactured by the 420W and 740W 36V frame manufacturer. The battery is not removable. To remove the battery, you need to remove the motor.

 

[LAnton]

The ZS BT 740 battery consists of 21700 cells

 

[thaeber]

Thanks for explanation!

 

[LAnton]

Thanks for explanation!

I will not install the battery in the frame. I will carry a 1500g battery in a triangular handbag. The weight of the battery case and wires is 1000g. We don't need to carry an extra 1000g on a bicycle.

 

[Bruce B]

I can't yet. The manufacturer asked not to give this information. Soon this frame will be on sale. We will compare three major manufacturers Dengfu, LightCarbon and incognito. And choose the best frame.

Try diy carbon in the US. I got my frame and m600 set up from Ty and it looks very similar to what you are showing here I wouldn’t rate him as a customer service oriented guy but I got my stuff eventually just no back up.the frame will take the 640 w and 840w BAFANG battery.
It handles well and seems to have good geometry.plus came in at 20 kg with the smaller battery I have it on 27.5 s and 170mm up front and 160 on the rear

Take a picture of your frame. Does the framework have a specification?

 

[Bruce B]

Here you go on specs and the quality is actually pretty good they take a 180 mm rear disc and I did fit a 215 rear shock and just had to grind the pivot trunnion out and turn the shock upside down

You're comparing apples with lemons, this has nothing in similar to the frame Lanton shared, bigger motor, heavier, 100% diff geometry, etc. You can compare it with the LCES004 from lightcarbon maybe.
Probably the only thing that's the same is the linkage.

 

[thaeber]

The geo of that frame is not really modern in my opinion. Short reach and slack seat angle / steep steering angle.

 

[endo_alley]

How's about this one?

Frame looks good if size „M“ fits for You. Headset specs look like not for tapered fork steerer (52/52). This would be a no go!

 

[thaeber]

Or this one?

Fits Shimano EP8 motor!

The best DIY frame I would be looking hardest at is the one that is available, affordable and with a company that has good communication skills in the language of your country. The last is the hardest to find but perhaps the most important, at least for me. The efforts of Jim and Ben here would make look in both places. Keep in mind their is alot of mold sharing going on in Shenzhen and most of the Aliexpress ones are part of that.

Having started mtb 40yrs ago and considering that geo has changed alot there are definite advantages to "modern" geometry, but I don't need cutting edge to get my ya ya's out and I am of normal proportions so fit is usually easy to acheive. Component choice bears more weight. Planning a swap next year from my M625 E22 frame to a M610 with compatible frame that fits the 48v 15ah 21700 cell stock case battery that I have. Completely gut my current bike but sell it on with the motor and a 52v 15ah 21700 cell battery. In the end hopefully not too much out of pocket.......

Do you ride in the mountains? Would it be comfortable with this battery mount?

 

[LAnton]

Do you ride in the mountains? Would it be comfortable with this battery mount?

My first electric bike was with a triangular handbag and a carriage motor on the frame, it did not cause inconvenience. A small and lightweight battery that is easy and quick to replace in the mountains, I find convenient. A non-removable battery or a removable battery as in the photo is very inconvenient. Who do you think makes this frame?

 

[thaeber]

Rear Triangle looks like Dengfu E10…

 

[bram.biesiekierski]

When I was looking around for my bike I found bikes like that one with the zig zag top tube claiming to be dengfu e10/e22.

 

[LAnton]

Very similar to dengfu. I don't like this design. The battery must be removable. I wonder how much this frame weighs. They don't give me this information, only photos.

Not sure of the model number on this one, but looks like a good alternative to the E10 and uses the same size shock (albeit giving 10mm more travel on the rear).

I saw this somewhere already. Remember the extremely low BB @ 327mm. Looks like the Kabon

It doesn't seem there are many longer travel bikes with the bafang M series motors and a BB that isn't too low.

 

[vext]

Has anyone built with it considered this frame..?

https://m.aliexpress.us/item/3256803833660737.html?gatewayAdapt=glo2usa4itemAdapt&_randl_shipto=US

 

[vext]

Anyone try building with this frame?

Shenzhen Winow Sport Equipment Ltd-Professional carbon mtb frame, 29er mtb carbon frame, xc mtb frame, cross country frame, 29

Winow EF49 - It looks promising...

29er
2.9KG
Set up for m560, m600 etc
840w battery
Enough travel

Any thoughts?

 

[endo_alley]

and a BB that isn't too low

I wonder if you could use offset shock eyelets to raise the bb a little? Or a slightly longer eye to eye on the rear shock?

Original spec shock length is 210/61 mm. You could use a 216/63 mm shock and finetune the length by using offset bushings.

The VMG bikes Typhon has been around for a while now. Modern Enduro geometry.
