Picked up my bicycle yesterday and I'm loving it. Met a friend today for a small tour, and we started near where I work so got to try out that route. A lot of it are dedicated bike paths so my contact with rush hour car traffic will be minimal.
Last Bike I owned years ago was my Dad's former 16+ kilograms Iron Hulk. That one would be 15 or 20 years old now. This new one is so light and runs so well that it's a pure pleasure to ride. Really amazing how much better they are today.
I suppose 2x 30mins a day will not be a bad cardio workout.
