We believe in technology, fair pricing, and friendships.

Our Background

Back in 2013, we started building bike power meters based on a patented optical sensor technology from Danish Technical University. This sensor technology turned out to be not quite mature, so we devoted ourselves to the known and very well proven strain gauges technology.

We are passionate about two things, technology, and cycling. Bike power meter products are a great combination of the two – incredibly hard to fully master all the details of the technology involved, yet so simple.

Our first product was the core technology – electronics and software and we sell that to brands who want to integrate power meters into their product lines.

In 2016 we decided to take the technology to the next level by building power meters for the end user as well. Through a quite successful crowdfunding campaign, two power meter products were developed.


The cycling industry has taught us a bunch of things about power meters and we instantly knew what we wanted to change:

– Testing by pro riders may be extreme in power and intensity, but it’s not as diverse as the riders actually buying the products

– The difference between power meter algorithms surface when they are put in real life situations

– Results generated by the pro riders testing our technology for the brands is not nearly good enough for us


We think differently. So, we decided to take a new approach and base our product development on crowdsourced data from our users and introduced the world’s first subscription-based power meters.

Why? Because we want better algorithms, better price, better products that work better for your style of riding

We started our Kickstarter campaign to make an open and super diverse test team for power meter testing.

But we don’t stop there.

We still want testers of all types, riding all types of bikes, on all types of terrain to join the growing test team for power meter technology.

Our Goal

The primary goal is to use diverse data to optimize the software algorithms. As we continue to evolve the technology, we challenge the testers to get on the bike and provide us with at least one 30 min ride tracked with our app every month.

By the way: In exchange for uploading the data, we offer a good a deal on the power meter.

Constant improvement is the name of the game and our Team ZWATT members will make their own power meter better.

Our mission is to bring our test riders together and to provide the best road, cross and mountain bike power meters so affordable that you would have one on all your bikes.

Join the Team

Let’s be social and keep up to date with our latest news and stories.  We are on a bunch of different platforms, but every one of them is very special.

Join the dialogue and become a fellow #TeamZWATT member.
