No, you should switch to a two-speed.


I ride around a lot on my single speed fixed gear bike. But when I ride to work I take my 21-speed hybrid. There are several reasons for this: 1. I carry extra weight of my clothes, lunch, towel, etc.; 2. I have to climb several hills on both the way to and from work; 3. I almost always return in a headwind, and when I'm tired from the 17 or so mile ride into work and hop back on the bike for the return trip, plus carrying the weight and all the rest of that, I enjoy using the drops on the wind (I installed drops on my hybrid; the FG has a straight bar).

If your commute isn't hilly, windy, or particularly long, and/or you don't carry much, you may want to go with a single speed.
