Need help with a build

[999zip999]

I run a muxus 3,000 v3 4t @ 72v 40amps. It works great. In a old giant. Most hills 30mph Or 36mph big and heavy. I hate the weight I don't know what to do I do have a 35 mm stator called a 1,500 watt.
How about a leaf D.D. 35mm @ 52v or a bafang HD mid-drive.

No worries that's nothing I've seen people tripped walked on and called a rainbow of names.

Not at all interested in a mid-drive but green leaf I keep hearing about them
