The good news is that you're rarely going to need the lowest gears. With a two stage reduction drive you'll spend most of your time in the middle to outside gears.
Another idea that I'm playing around with is a wide ratio 4 speed based on 8 speed spacing. The four cogs will be grouped in the center to minimize cross chaining. The outside two sprocket spaces top and bottom will be eliminated.
Try running the bike and see how it does. Derailleurs are made to run this way.

I'm close to getting my 1500w rebuilt up and running.
I recently mounted the motor and chainring and noticed a fairly aweful chain line (Please review picture)
Does anyone have any idea's how I can improve my chain line ?
