You do know that one of the main purposes of riding a bike is to get exercise right? (which is coincidentally the top reason I don't ride one )

Heh. Yeah. My office is only about 5 miles from my house, but I'm WAY too lazy to bike up the two big-ass hills between here and there.
I need to mount the sealed batteries - planning to do 2 on each side of the rear wheel, pannier-style. The lead-acid batteries are heavy, but they're too readily available to ignore given how much lithium batteries cost. Rack-mount uninterruptible power supply units typically have 4 12-volt batteries wired to make 48 volts. Plus I'm fat - an extra 15 pounds of battery is NOT going to be the make/break point for the project.

Public Service Announcement: if your suspension fork has magnesium lowers, you'll want to replace those. Axe me how I know.

If you haven’t already fixed this, I’d recommend ditching the suspension fork entirely. A suspension-corrected cro-moly fork will be lighter than the suspension fork and far stronger. Both Surly and Soma make good, solid suspension-correction forks.
You need to get a fork with the correct axle-to-crown length to keep the original frame geometry. You can find tables online that list the correct fork size based on wheel size and fork travel.
For my hybrid — 700c wheels and 50mm of suspension travel — the correct fork had A-to-C of approximately 465mm.
