Buy an allen wrench set so you can assemble it! Sounds like there isn't much around you so a METRIC set may be scarce. You'll need a 4, 5, 6mm, and possibly a 3 or 2 mm for brake adjustments. An 8 mm is also good to make sure the crank bolts are secure.

Other than that, the only other think you'd need is possibly a 15 mm or adjustable wrench for the axle nuts. There are other things that should be adjusted, technically, but you can probably get by without doing them for now as they aren't safety related.
