Keiser m3 vs Garmin Vector

Gino introduces the Power Pedals research study

My last blog post was ended with this statement: “This blog represents the first in a series that will be exploring power and how we can make it more accessible, more understandable, more reliable, and more straight forward to teach with.”

To live up to those lofty goals, as an outdoor coach, an indoor instructor, and in general a man dedicated to getting the science right, the only place I can start from is one of credibility and truth. In other words, however I am going to try and lead someone to apply power and ultimately teach with it, it must be done with reliable and repeatable techniques. This is my only hope of also producing reliable and repeatable results in both indoor cycling instructors as well as our students.

The variability of how the same power levels feel on different bikes (specifically the Keiser m3 that we have used predominantly for the last 5 years) is something that has actually prevented us from doing lots of more engaging and/or fun training in groups. I don”™t want to push someone to work hard only to have the fact that they chose a “hard bike” today instead of the easy one be what determines their ultimate success in any competitive or group activity.

I knew that until there was a way to objectively verify what power I was pushing on the m3 I could not know what the truth was, and so I waited for an way to implement this objective measurement. It finally was made possible when the Garmin Vector power pedals were released. This video is the initial launch of this research study.

Video Agenda
After an initial introduction as to why I took on this huge research project, I show the details as to how the Vector Power Pedals were fit on each bike and the nitty gritty steps on calibrating these pedals before I could begin testing the bike. This calibration method had to be done for each bike, and repeated each time I repeated the test.

This video also is the first in a series of video blogs that will allow you to take this journey with me as I discover what is possible and what is not in the pursuit of establishing real power levels of the Keiser m3.
