Hi to all 
Long story short, got the CEF69 build last week.
FORK: RS ZEB BASE 170MM (BUTTER CUP AIR SHAFT)
SHOCK: RS SELECT 205X65
BRAKES: SHIGURA
BRAKE ROTORS: IIPRO 203mm-front and 180mm rear
WHEELS: DT Swiss rims (models as on the photos), Sapim race spokes, brass niples and KOOZER 455 hubs (32 hole)
TYRES: ALBERT GRAVITY RADIAL, 2.5FRONT AND 2.4 REAR
DRIVETRAIN: 11S LINKGLIDE
CHAINRING: 38T (max size)
BATTERY: 13S4P 48V 1000Wh Samsung INR21700-58E (CC5563F101)
!!!BBR V2 FROM DADO !!! --> HIGHY RECOMMENDED
BACK FENDER: RRP Proguard Front Mudguard - SHORT
DROPPER: ONEUP 210mm slammed all the way down as insertion lenght of L frame is only about 295mm.
PEDALS, SADDLE, STEM, HANDLEBAR: got it on ALI
WEIGHT: 24.5kG
Additionally I made a small module (about 30W max) for automatic LED headlight. I used Magicshine ME2000 light, gives plenty of light.
Build wet nice and smooth, there was only one small surprise (experienced also with CEF55), frame motor mount have excessive clearance, in this case I had to add 1mm distance/spacer washers in order to bolt on the motor tight to the frame. My advice is to place those washers on non drive side as it affects chainring clearance.
A few photos of finished bike bellow:
Done first ride, bike feels great, goes through the corners. I was a bit afraid about bike balance due to a big battery stashed in the down tube but I turned out this is not a problem. IMHO this is a good platform to build a capable enduro bike.
One thing that might need improvement is the flex at the back wheel, it is not disturbing in any way but it could be better. If there was a bridge in between seat stay's it would be way better.
Now the M510 FC4.0 motor.
Done only 40km but first impression are:
-my motor is in noisier (motor+gear whining noise) than FC2.1 I had before (that one was super silent),
-clutch tolerances are tighter, there is a fair bit of a resistance (new motor) when trying to spin the cranks without the chain, but the other ting is, when I was rumbling around local forests/trails, it was perfectly silent when going down, I couldn't hear any noise coming from it at all. Maybe afet a good few km's it will loosen up a bit.
Power - max i was able to squeeze out of it was 680W.
ECO - 150W
TOUR - 280W
SPORT - 415W
SPORT+ - 540W
BOOST - 680W
So the stock tune is about 130W in between the modes.
Power is delivered smoothly, to reach max value You need to putt a fair amount of power into the cranks Yourself.
This motor with stock tune will NOT blow You away.
In next few weeks I am going the check motor efficiency and try to answer myself:
Is it really worth it to get M510 over M820 for sake of 80W extra power ?
Regards
Peter

speed sensor.
You could ask Dado from K1 Flash he has the M510RS or firmware but for 36v just need to change the settings for power management.
