charly have share it several months ago. raison why i have ordered one

They do provide the 835Wh carbon battery by default. I dont have dimensions because its in the bike now, but I'm 100% sure some thread on this forum already has it.
 
200km in! Bike has been a blast. Pretty impress with the battery life and the power of the motor.
One thing I wish for the bike right now is that, a link for an MX setup. Or a rear triangle for 27.5 setup.
Current setup is a 170mm front and a 65mm stroke on the rear.
Bike is pretty linear, I needed two token on my rear shock and I'm just about 120lbs.
I typically get away with one only. Overall, pretty rad bike for it's price.

I'm trying to modify it so there could be a yoke with a flip chip to allow 29 or 27.5.
I've been checking some CNC pages that they fabricate based on a step file and it's Circa $200, but I believe that number could go down if there's a big order, or also hopefully Jean can fabricate them in China and include it, i'll share it with him as soon as I have it ready and tested by 3d printing it.

so can't an offset bushing be used instead of a flip chip?
 
Running 27.5 instead of 29 is only a 14mm drop, less if you run bigger tires (like a 2.6 in 27.5 is the same diameter roughly as a 2.35 in 29er).

Just run it and be happy. Don't need flip chips for that stuff. Worse comes to worst, slightly shorten your stroke length on the shock.

Before working on longer link (that simulate flip chip), have you checked if you can lowered the rear triangle beyond the 205 mm of the original shock absorber ? impossible on the Cef50, raison why i can't use it in mullet

Yes, I do have the step for the frame so extending it to a level that the rear triangle doesnt interfere with the frame by going lower.
It's hard finding the balance of how many mm's I can move further without interference, cause the real difference is 19mm to keep exact the same BB, best doable is 10mm by making the link 3.3mm longer between shock and the other link, getting to a midpoint

Thank you for your hard work. $200 is really steep. But I'll be down to start saving.
I wish i could help but i have no knowledge about engineering that kind of stuff.

Oui, j’ai la marche pour le cadre donc l’étendre à un niveau où le triangle arrière n’interfère pas avec le cadre en descendant plus bas.
C’est difficile de trouver l’équilibre du nombre de mm que je peux déplacer plus loin sans interférence, car la vraie différence est de 19 mm pour garder exactement le même BB, le mieux à faire est de 10 mm en rendant le lien 3,3 mm plus long entre l’amortisseur et l’autre lien, en arrivant à un point médian

Dans ce cas, il serait peut-être plus facile de remplacer un amortisseur arrière 205 par un 215 classique ?
