Just saw a post from Seraph bike company about a new M820 frame. Can't really see the travel numbers, but looks like a long travel enduro frame. Good to see a growing supply of different frames. Still waiting for a shorter travel option.

Nice to see other frames with this motor! this one looks nice, you have a link?
 
Nice!

It states that it is a 150mm front and rear frame. the 180mm is for the rear disc brake
 
They made another m820 frame that they sold the exclusive rights to pretty quickly. The geo numbers look good to me on this one, could be a solid option for an all mountain lightweight E-bike. It doesn't look like it has a UDH though.

For my kind of riding. With a non e-bike I would go for a modern cross-country/down-country bike. We have a max of 30 meters of elevation, with mostly smooth single track and fire roads where I normally ride. Therefor the best option for an e-bike for me looks like a 130 to 140 mm, lightweight, mid assist e-bike.
 
What is interesting, is that front triangle of this frame has EXACTLY the same dimensions/angles as an LCE930 from ligthcarbon. They must have co-develope it together.

Another interesting thing is, that chainsty length is listed as 440mm, whitch is 17mm shorter than LCE930, but overall wheelbase is only 10mm shorter. THere must be some error (here or on LC site), considering front triangle has the same dimensions.

Just for the lulz, I overlayed two geometries together, and as you can see, the front triangles are exact match:

The motor mounting holes, chargint port, chainstay mounting point, rocker mounting point, seat tube and head tube are in the exact same location. Chainstays and seatstays are a bit different. And ofcourse, shock is driven via the yoke, instead of the rocker arm.

depend of your use, 180mm (imply long wheel base and heavy forks) is valid for DH / bike parks, not for technical tracks and those who looking for lighter and ride on flat tracks, 120/140 with 34 fork diameter is enough and allow to win several undreds grams

Or they measured with different fork lengths / offsets or something.
 
Interesting frame! Basically same as LCE930, 150mm travel is pretty good for do-it-all bike, especially ebike. 563mm A2C seems to suggest 160mm fork. But that shock size!! Why would they ruin it with an old standard??

wow, looks really good!

@Lehr, do you maybe know what headset is used here? It looks better than the one with LCE930, but should be cross compatible.
