16.3 kg = 35.94 lbs.

Do you have a scaled-weight pic?

Battery is is in it? (410 Wh?)

I forgot to put the battery

When shock has no air, what's the rear tire clearance to the back of the seatpost?View attachment 113153

20мм. I have a 29x2.4 wheel

20мм. I have a 29x2.4 wheel

It's looks the bigger travel, 55 mm shock stroke will likely clear easily with a 27.5 x 2.8 rear wheel!

Looks great!

Just need a pic of full build with battery in it on a scale?

I'll pick up the 15ah battery next week. The weight of the battery is 15ah - 2150gr, the weight of the battery is 10ah - 1500g.

I'll pick up the 15ah battery next week. The weight of the battery is 15ah - 2150gr, the weight of the battery is 10ah - 1500g.

So, you have the downtube battery as 410 Wh?

Also, what size frame? Large or medium?

 

[LAnton]

Bafang promises to make a motor weighing 1 kg and a 20ah battery with a capacity of 0.8 kg. In 3 years we will ride light electric bicycles.

 

[TCFlowClyde]

. The weight of the battery is 15ah - 2150gr,

So, 16.3 kg build (w/out battery) + 2.15 kg 410 Wh battery = 18.45 kgs/40.68 lbs?

Frame is Medium or Large?

with Mullet it will be save using 210x55

 

[temon10]

can u tell us some component detail ?
- Handlebar and stem?
- Rims and freehub?
- Groupset?
- Dropper seatpost?
- Tire?

It won't work. You will break the frame, see the photo.

 

[TCFlowClyde]

A 210x55 should work with a 27.5er wheel...clearance looks good!

 

[temon10]

We'll see when my frame arrive. Thanks for your caution.

I think the problem LAnton is seeing is the pivots binding carbon on carbon, not the tire striking the frame.

 

[TCFlowClyde]

I think the problem LAnton is seeing is the pivots binding carbon on carbon, not the tire striking the frame.

But the eye-to-eye fitment is still 210. It should still accommodate a 55 mm stroke. So, the frame friction of the rocker arm hitting the seatpost mast is unlikely. But we'll see for sure soon!

 

[spokémon]

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

You must mean this pivot?

 

[Olafmetal]

You must mean this pivot?

yeah if that rotates to far it would bind.

I doubt it

@stuff thanks for the pics. Is the bar made of alloy?

Nope, a 210x55 likely won't bind.

A 216x63 might.

But we'll see. Let's just wait for a 210 x 55 fitment on 27.5er before speculating too much! If it doesn't work than just reduce the stroke to 50 mm. Most shocks, it's fairly straightforward.

 

[Fresh]

I'm pretty sure his 2nd image is wheel at bottom out. I think 5mm more should still be okay

Nice! what's the wheelset weight?

Yes the handlebar/stem one piece looks great.
Do you have a close up photo of cable routing into the headset?
