Hi all!

I am a new bike enthusiast and I already have questions! First of all I'd like to thank everyone in advance for the patience since I am new here!

My explanation might sound a bit noobish but here it is:

I want to know I have a fixed-gear bike - pretty good one, but the tension in the chain is too low - it is like pedaling on 1-2 gear - thus needing a lot of effort to achieve speed. I want to tighten the chain to make it have more traction as if you are pedaling a bike on 4-5 gear. Is that possible?
