So is that Jm's LC930 in the video?
NO can't be with the curved top tube. So I wonder where that came from?

Not that I recognize.

I was wondering the same thing to, what bike is that, do you have an XL and will you ship to the US?

 

[TCFlowClyde]

Here's Jim's called the Karbon Power line SL.

Hi @LAnton or @stuff Any chance you can show a photo of the internal battery mounting bracket for this frame?

 

[spokémon]

Jean told my frame was painted and the motor would be ready in two days but the 410wh battery is being revised and delivery time will be longer.

I hope not a lot longer.

I got a similar story from Linda re 410wh battery delays. She also ordered a 165mm crankset for me from Bafang instead of the 170mm but it is also delayed.

I see lots of bottle batteries with 36v and 48v on AliEx. Does that mean those of us with 43v systems are out of luck for bottle batteries?

 

[mike_kelly]

That is why I picked 36v. I knew I wanted an external battery and 43v is not standard.

if choosing Bafang 43v battery, U have to wait Bafang release their extender battery.

The interest to use bafang battery, is that BMS can communicate with the HMI and you can displayed several informations of the battery use. For what i know, nothing other batteries can do that. in addition of you don't need to build adaptations to usfix the battery.

I've almost finished assembling the bike. The battery is attached with 4 bolts to the frame. There is no bracket on the frame, only holes in the carbon fiber. Also, 2 bolts for the bottle holder are attached to the battery through the frame.

Attention. A shock absorber with a stroke of more than 50mm cannot be installed. You can break the posterior triangle.

So 210x55 can't be installed?

Added some zip ties to strengthen it up since its attached to only 2 bolts.

Also 3d printed some supports so its a tight fit

 

[stuff]

Battery wasnt 100% in here, but you can see irs a tight fit with the 3d printed supports

This were some initial prints testing fit

 

[LAnton]

You can . But you will break the frame when you ride a bike. I have reduced the stroke to 50mm

I have a different battery. It is made entirely of aluminum. The battery is attached to the frame with 4 M6 bolts and 2 bottle bolts.

Yes, your battery is not the bafang 014 one but the custom

Oh - 2.8 kg - that’s heavy for only 410 Wh. One more kg and you get 720 Wh…

29". With the 29 wheel there is still a margin of 2 cm. Pairing the parts in the photo does not give more progress.

More photos of your rear triangle please. Maybe deflate your shock completely and compress fully, then take a pic?

This bag includes 15Ah. The bag has plastic inserts on the sides. The bag is fixed very rigidly. The weight of the bag is 150g.

How was the headset install? It fits ok?

 

[LAnton]

The weight of the bike is 16.3 kg.

The headset works very well. It is necessary to blunt the sharp edges on the headset so that the wires do not spoil. I wrote to Jean, they promised to fix it. Very convenient, the steering wheel rotates easily, by a large degree.

16.3 kg = 35.94 lbs.

Do you have a scaled-weight pic?

Battery is is in it? (410 Wh?)

When shock has no air, what's the rear tire clearance to the back of the seatpost?
