– Upload 12 FTP tests for a cheaper power meter

We are launching a new study to invent algorithms for new useful metrics creates an opportunity for all you committed bike riders to get a power meter on your bikes.

What is FTP anyway?

The Functional Threshold Power is the maximum power you can currently produce for an hour. But no one likes to do a perfectly paced 1 hour time trial, so the 20 minute FTP-test was developed. Simply put: You do a 20 minute all-out test and take the average power from those 20 and subtract 5% to produce your current FTP number.

We just released a beta version of our Android app with a dedicated FTP-20 data field to support the study. All you need to do is to download the App (sorry Android only) and do the test and share it with us by uploading it to our server.

Who can participate in the study?

Every bike enthusiasts who’s interested in participating will need to perform one 20-minute FTP test per month and upload it for our engineers to work on. Only Android users in EU are invited at this time. We will provide the Zpider power meter at an unusually low price of €250 plus a monthly fee of €10 for 12 months. Accessories such as chainrings and bottom brackets will also be available.
