Buy or build a rear package rack for your batteries--This will also give you something to mount a boat tail to.
I checked out zzipper and that could be a good starting point for my fairing(s). Thanks for the info. I will def look into that.

I realize that chainrings w/ less teeth up front won't net me more speed. My reasoning behind that mod idea is to stop the motor controller from shutting off due to overtorque requirements placed on it when going up hills. Right now when I go up a hill, the motor frequently shuts off (usually at the worst possible time). I'm thinking it just can't keep up with the required torque. I noticed it happens less when I'm in the lowest gear (28t sprocket front and 30t sprocket rear). I'm imagining if I go with a 22t front and 34 rear when climbing a hill, there will be less torque rqmts placed on the motor and it will not shut off. Is that a valid assumption?

I know that my top speed is being limited by wind resistance b/c when I get to around 22mph on a flat surface and try to shift to a higher gear for more speed, I actually lose speed. I'm thinking the only way to increase top speed is to either get a bigger motor (w/ more torque) or, reduce wind resistance. What say you?

I originally had the batteries mounted on the back (see attachment) but it made it so unbalanced that it fell over easily when on the kickstand. It also caused a spoke to break (when I hit a bump) due to so much pressure/ weight on the rear wheel. It basically rode like crap.
