Building bamboo bike

[mayobike]

I am currently in the makes of a bamboo bike. I have already finished the frame. However, I am having a problem piecing it together. It has a 1-1/8" threadless headset, 68mm english bottom bracket and 130 OLD rear wheel.
Weight, price, and efficiency is my goal. I am currently trying to find out what type o combination of gear ratio, wheels, cranks, and type of fork would be suitable for NYC riding. Thanks in advanced!
