My first post here on ES, so hello everyone
Been e-biker for a year, this is my primary ride:

Based upon MXUS 36V500W hub motor, Marin frame and Marzocchi fork.
Max speed 40-45km/h with some pedaling.
Wanted to build something faster, with usable gears and full suspension, so I ordered GNG 48V450W Mid Drive kit.
It arrived within 8 days; Jon at GNG is a great guy!
At the same time, spotted Giant Glory '09 frame at local used bike market, and had a feeling that those components might mate perfectly with some mods.
So, I repositioned the GNG mounting bracket by 60°, by simply moving it one mounting hole backwards.
Whole thing got linear, stretched look.

Primary reduction isn't affected, secondary will need longer chain
A quick scaled mockup in PS shows that things may fit well:

So I contacted the guy, tried everything in place and bought the frame.
Oh, the joy!
Everything is properly aligned and has proper clearance.
Mounting bracket had to be cut in half and had 15mm spacers inserted on the left side of the motor.
Also, I found a neat solution how to implement standard GNG BB 68mm axle into a 83mm downhill bike frame.
Gotta sort the pictures - more details in a next post
