For someone starting out though who likely has shit cardio...a bike is probably a good start, much like a fast-paced walk or light jog.
When you get yourself to the point that you can do full out tabatas and hill sprints, it is hard to really consider other forms as a cardio workout, plus add the time factor. Getting better results both aerobic and anaerobically in about 15 mins as opposed to 1-2 hrs is hard to wrap ones head around to even go jog, or bike for cardio.
Bearing that in mind, you don`t get good cardio by jumping head first in the deep end either. I wouldn`t recommend to anyone who hasn`t built up and worked at cardio, to do some of the best results oriented things unless they were prepared first by working their way to it.
