Upgrades for a bike when adding a motor?

    Today I finally finished my bike... it's just a generic mountain bike that I welded up a rack mount for, plopped a Harbor Freight 2.5 on, and bolted a sprocket on the rear wheel using bonded washers. I started pedaling it up to speed (it's geared rather low, and direct drive) and my pedal chain just broke. I know this probably shouldn't happen with any chain, I wasn't even pedaling all that hard, but it got me wondering if there's anything in particular I should upgrade. I've already repacked the bearings with white lithium grease, and I was planning on getting new brake pads. Anything else I should look for?

    A good SRAM or KMC chain should be durable enough.
    Make sure you have a front brake of some kind.
    We can make better suggestions if you can post pics.
