Hi everyone, I just bought my first real bike, and I am a total novice. I know a little less than zero about bicycle mechanics.

I am planning on riding to and from work, and to the gym I go to after work. I will be riding at night so I want to get dynamo hub and a set of lights, front and rear.

I dont know alot about wheel sizes, hub holes, etc. Can someone point me in the right direction?

Here are the technical specs on the model I got.
2014 Vaya 2 | Bikes | Salsa Cycles

HELP!
