Hello,
I just started commuting this week, it is my third week on new bike.
My commute is 6 miles one way and pretty flat (I'm OK with that)
Most people seem to think a bike is a toy but if you are riding to work every day that is a game changer.
Of coarse if commuting is the goal it takes more than just a bike, got to have other stuff and it all cost money, helmet, lights, lock, something to haul stuff in, pump, flat repair stuff and OMG where does it end. Did I mention I don't have a money tree in my back yard.

My car ride to work took me about 15 minutes on mostly a four lane race track, aggressive driving and drivers, since it is what I have always done I never really thought about how aggravating the obligatory commute is.

My bike commute takes me 35 minutes, have to stop and cross 3 four lane rodes of death but other than that it is casual neighborhood ride. I do stop (rolling stop unless there is actually another car around) for numerous stop signs as well. But it is peaceful, easy, not stressed out. When I get to work I am wide awake and in a good mood, not always the case when car commuting.

But I'm preaching to the choir right?

Happy to be aboard, sure wish I had figured this out a lot sooner.
