It saddens me that we actually have to do this on every page .... Page 10 Thread re-cap ..

As per our last re-cap for those that didn't tune in, you can click on the images to enlarge.

Or, you know, like maybe, possibly, read the thread ???? Who knows what else you might find out.

You are correct.
According to a tester they only got 600km from the XX cassette on the s-works version. (im sure it was hammered pretty hard during testing) but it makes me want to perhaps switch to Linkglide .... but I notice the S-works frame has no cable ports.
One does not mix S-Works and Linkglide, it is unnatural until proper marketing fixes it

Zim started another thread for Images and Specs, please post them in there, or check in there for new ones.

Discussion can continue in this thread. Maybe ?? that will stop the endless duplication ? Ok, no chance ....


Both threads are stickies, so easy to find in the Spesh section at the top.

I'd be most interested in this as I find the DJI to have a really broad range of power but more importantly control over that power.......its like no bike I've had or tried before. It really is it's secret, not he headline figures.
I find that my last S works was much more tuneable than what the DJI is.

If the Revolutionary feature is having a main battery and a secondary battery option in frame, that's not new,

The Fulgur Mula had that 4 years ago.

If this had the possibility of only riding on the 280pack when needed (making it 2-3kg lighter, that would be amazing)
That possibility is definitely possible to implement from a technical standpoint, although from an electrical standpoint the power the extender can safely continuously deliver is much less, so it would work only with reduced power output.

23.5kg, is that a joke, for 14000euro? This wight you can buy for 8000euro, or dji for 6500euro 21kg give me a reason where this is justified to buy?

Can anyone post the prices again please? I know I saw them in the 118 pages.

Thanks!

So, we have established that the range extender is external and 240 W. Can we confirm that when paired with the main battery of 600W or 800W, the added power from the extender is drained simutaneously w/ main battery (as is case with the present Levo SL), meaning that the 50 % power restriction of the Extender (only) application would not apply?

When I asked if the extender would mount externally, I was told it also goes into the downtube. I was surprised/skeptical but have no reason to doubt my source. I assume he meant the main and extender batteries would be in there concurrently rather than one-at-a-time. But perhaps you'd be limited to what combinations of different capacity batteries would be allowed (e.g., would 840Wh + extender be supported?). I got a quick glance of a photo of the 840Wh battery but couldn't determine its length.
The new Levo downtube reminds me on my all newer downtubes with Bosch new 800Wh packs.
For example the downtube on my Reign is cca 500mm long(the battery opening)on an M model. The battery size of the 800Wh pack is 440 x 85 x 78 mm.

For example the Dji 800Wh battery that is built thiner but longer compared to Bosch is 561mm long, it's probably one of the longest batteries I have seen.

For example The Bosch 800Wh pack has

dimensions of 430 x 75 x 81 mm

and the almost square shape(cell stack) seems to me that it could fit pretty nice into the Levo downtube so I will take it for reference.

Let's do some math:

Length 430mm/800Wh = 0,5375mm/Wh

Levo:
840Wh x 0,5375mm/Wh = 451,5mm
280Wh x 0,5375mm/Wh = 150,5mm

Together that makes 602mm of length, if we add say cca 13mm for connectors between packs, that adds up to 615mm of combined length.

The downtube of the Levo would need at least 615mm of open space to just fit the two packs, aand only tthen after the motor space and steerer tube space of the fram comes into play, don't think it's possible.
I believe that only the smaller battery and extender can live simultaneously in the downtube.

The extender looks to be more rounded like a bottle cage type mount. Where as the main 840wh battery looks to have some intrinsic rails and maybe a connection latch.

The 600wh battery appears to have a built in structure to make it mount in the same space as the 840wh - so no space for a range extender with it.

If the extender was supposed to be in the down tube as well, I can’t see why you would need such a long cable. You’d assume it be on a quick connector.

As far as the battery pack config goes I think the previous poster #187 was incorrect.
13, not 14 cells in series is correct for 48v.
14 cells is for a 52v system.

My 23’ Levo is 36v with a 700w battery, pretty sure there using 21700 cells and it’s a 10s4p
It's depends on what motor(load) is used, the exact voltage on wich it's is rated.

I did elaborate the difference between 13S and 14S in my post #819 in December 2024 in the previous forum and will not repeat it here.

Just a recap, electric systems have losses and to negate them it's good to go a bit higher with the voltage. Yes I agree it could be a 13S system, but then the 840Wh battery pack mentioned in the specs isn't physically possible.

Capacity is calculated at rated cell voltage that is between 3,6V and 3,7V for 21700 cells.

13S3P = 39cells × 5,5Ah × 3,65V = 783Wh
14S3P = 42cells × 5,5Ah x 3,65V = 843Wh

Hope this clears thighs a bit✌️

So much about my wishes and theory 🤷‍♂️😂
