Kona power meter usage trends: 2009 to 2017

Kona power meter usage trends: 2009 to 2017

Update for 2017 based on the Lava Magazine bike count data. Previous posts links showing trend data up to 2013, 2014, 2015 and 2016.

This chart shows the trend in relative usage of power meters since 2009, along with the total number of bikes (click  on images to see larger versions):

Here are the numbers. Data in order of year of introduction.:

In the nine years of this data being available, power meter usage has risen from 17.3% of all bikes to 58.7% of all bikes, although the growth slowed  this year, and was well below the longer term trend of an increase of 5.5 percentage points per year.

Finally the year on year change data and order ranking:

Not too much change to report compared with last year.

Stages is the big loser this year with the largest fall in both overall numbers and in relative share, dropping one ranking place from 4th to 5th most commonly used meter at Kona.

For another view, DC Rainmaker has this year done a similar analysis.
