Exercise Bike Comparison Guide: Stages SC3 vs Keiser M3i

Exercise Bike Comparison Guide: Stages SC3 vs Keiser M3i

The popularity of some exercise equipment and workout techniques come and go, but not indoor cycling.

Indoor exercise bikes have long proven themselves to be a staple for any good home gym, and that doesn’t appear to be changing any time soon.

With that in mind, we’ve taken two of the most popular and functional exercise bikes, Stages’ SC3 and Keiser’s M3i, and pitted them against one another.

In this post, we’ll briefly discuss why your home gym simply isn’t complete without a good indoor exercise bike as well as detail the main differences between the Stages SC3 and the Keiser M3i.

Let’s take a look at them now.

Benefits of an Indoor Exercise Bike

There is a ton of awesome benefits to owning your own exercise bike, here are the main ones:

  • No excuses: Whether it be extreme weather, a lingering pandemic, lack of time, or simply for convenience, having an exercise bike in your home gym means there is never an excuse not to get a much-needed cardio workout in.
  • Data-rich training: A quality exercise bike offers athletes the opportunity to collect a massive amount of workout data. Metrics like heart rate, VO2 max, pedaling effectiveness, and revolutions per minute are all easily tracked and recorded for later reference.
  • Immersive cycling experience: Indoor cycling bikes offer athletes an immersive experience that is not only realistic but also super motivating. Features like real-road feel, handlebar-mounted air fans, gear change simulation, and downhill drive inertia make the transition from the open road to indoor cycling that much more exciting.
  • Proven fitness and health results: Regular use of indoor cycling bikes has many scientifically proven fitness and health benefits. Studies have shown that the use of exercise bikes helps lose weight, reduce blood pressure, increase cardiovascular health, and improve lipid profile (a measure of cholesterol and triglyceride levels).

Stages SC3 and Keiser M3i Pros and Cons

Both the Stages SC3 and Keiser M3i have their own advantages and disadvantages. Let’s take a look at them here:

Cons:

  • Cannot be folded away for storage.
