finally done the motor mount and made things work
it also reinforce the loop , was done in 3 parts plates welded together ,holes drilled in it , screwed extention nuts on both sides then welded.
i left about 3/16 space for washers to dial-in the offset of the motor.
I re-cut the ''motor drive side'' aluminum support plate to use as spacer for the crank side . now its super strong!
as for the motor side , decided to make a star shape steel support that is thinner/stronger and allowed me to mount the disk brake caliper. it also look awesome imo
modified the caliper to remove the cable hanger cause it was sticking out and looked bad (ill make one on the motor mount) .. also grinded it a little to clear the the sprocket and chain behind ... and finally to drilled a new tiny hole for the spring inside the swing arm to rotate it where i wanted it
and here is why i wanted to put the weight in the loop instead of playing it easy using it as a rear hub .. 50lbs about 17 for the motor and 33 for the frame+wheels .. the battery is about +10lbs ..
still not bad to lift . about the same as my cargobike i think
Battery is finally ordered , going with 48v 20ah
