The frame looks great, nice and simple, and the bumper mounts are a very clever approach. I'd avoid cheese-holing it if I were you... It's already very light! Just put as much thought into your mechanisms as you did into this drivetrain and you won't have any weight problem at all.
And belts are awesome!

$6-7 a piece (about $15 each if you get them with aluminum hubs):
