I contacted Yuying regarding their EGR-2, the one advertised on Alibaba. They quote 15% discount price which ~2294usd, exclude shipping.

more details:
-LTWOO GRT 1x12 group.
-Thru-axle.
-options for front fork: suspension fork or rigid carbon fork. Same price.

attached their catalogs.
At this point I'm very tempting. Since it's a mid-drive and full carbon. Comparable price to the Ride1Up CFR1 but with much better mid-drive motor instead of hub motor.

BTW their have a hub-motor version which is only half the price around ~1k usd.

I would love to have one that fits the Bafang M560 motor.   If I go electric, I would want all the power I can get!!!

I believe the M820 is nice, but there is growing competition by several other manufacturers regarding smaller and lighter motors that have more torque than the M820.

Has anyone built this up yet? I am in the market for a new
Bike with more off-road capabilities and dabbling with e bikes for hauling loads up hills.

I just saw this thread.

Use the Salsa Cutthroat as your baseline for frame geometry.   Then go to this website and find the Aliexpress/Brand frame you are interested in and compare it to the Cutthroat.  This will give you an Idea of what hardtail frame will work well with drop bars

I am using my Spcycle M05 for my bikepacker these days.  It is a longer frame and slacker than the Cutthroat, but I am still able to run drop bars as needed.   This being written, i evolved to where I use a set of "H" bars on this bike rather than flared gravel drop bars.   The nice thing about this is I can reconfigure the bike to flat bars in about 20 minutes, often swapping out a rigid carbon fork with a suspension fork.

Edit:  The nice thing about "H" bars is that you can run mtb components/levers on the "H" bars because they are the smaller mtb flat bar diameter.  With Gravel bars you are stuck using integrated gravel/road brak/shift levers, adding a lot more cost to your build.
