Hi!
I’m new to the scene and looking to build a lightweight bike based on the M820.
I’ve been looking for a 130mm full sus bike with frame weight sub 2500g, but it seems all the available frames are 160mm+.
That’s counterintuitive for a light frame based on one of the lightest motors, in my opinion.

My dream build consist of a modern geo 130mm frame that is sub 2400g in size large and have a display built in to the head tube, M820 motor, sub 3000g 600wh battery , FOX 34 SL 130mm fork, carbon wheels that is sub 1300g with 30mm inner diameter, sram gx axs and a lot of other goodies.

The closets I have gotten this far is the Leichten, but I can’t find the bare frame.

Does anyone know what frame this is?

Good luck with your project, are you aiming at a specific target weight?
For the wheels, I could recommend to use Extralite hubs, laced with BERD spokes onto SLS4 rims from Duke. You’ll be sub 1,3kg weight without any fear!

Thank you very much. Don't know how I missed that.
Like I thought, the frame is too heavy.

The best candidate this far is the CEF55. Designed like a bomber and all I really need is a HT, but that's ok.
(Does anyone know if there is a HT frame designed to use the M820? Could potentially be a sub 12kg build)
Only downside is the lack of size Large.

@BenCatalan Thank you. Not a specific weight, but we can put it like this:
I was about to buy the Orbea Rise SL LTD, ended up wanting to perfect that with some minor tweaks, realised I need to build to be happy.
If I can find a frame that starts out sub 2500g that can make use of one of the new gen XC-type forks I think 16kg is within reach with a 480wh battery.

It does make sense and if you spend the right amount of money, it's doable: Look, after some maths on total sums for an AllMountain built: small carbon housed battery, strong LightBicycle carbon loops with Onyx hubs, real strong 29x2.4 Radial in DH casing tyres; Mezzer 170mm fork and Mara Pro 216x63 shock (should give 172mm of travel), Hayes Dominion on 200/200 rotors and a SRAM T-Type GX groupset. The weight should be around 18,3kg ready to roll (pedals and tool included).

I've been thinking about the Fox Factory Grip X2 140mm. It comes in around 1750g and saves me 250-350g when compared to the 160mm+ forks.
I was originally thinking of the 2026 Fox Factory SL but it seems the a-c is way too short. I need 550-580mm for the CEF-55 frame.
The bike you're describing is actually very light for a bomber with 170mm+. Thank you so much for the input. It might be a route I could take.
The battery has a claimed weight of 1950g for the 480wh. The range extender is claimed around 1200g for 280wh. That gives me a total of 3150g for 760wh.
The total price of the project puts me in the Orbea Rise M10 territory I think, but it will be lighter and more as I want it.
