The Body Rider BRD2000 is a combination elliptical and bike. It uses a conventional chain fan system that produces moderate resistance, though it can't compare to higher-grade magnetic systems. Also, the resistance can only be adjusted with a knob. There are no resistance buttons.
The benefit of the BRD2000 obviously is that you get dual functions in one budget-friendly machine. The problem though is that the 'stride' is very short. This makes the machine not too great for people who are tall. All in all, it's a cheap way to get two workouts in one.
