For comfort reasons, if your pedaling speed goes below 55 rpm, the PS900 Bike reduces the resistance on the pedals, so they won’t feel like they are “locking up.”
How Your Bike Controls Your Workout
CHAPTER THREE: MANUAL AND PRE-SET PROGRAMS
The PS900 Bike closely controls how hard you’re working, so that you get just the workout you’re looking for.
It does this by keeping track of both how fast you’re pedaling and how hard you’re pressing on the pedals. At any given level in a workout program, the PS900 Bike will keep your exercise intensity constant,
no matter how fast you pedal. Technically, this kind of workload control is called constant power.
