Team ZWATT (by SENSITIVUS gauge)

Get more out of your training on a bike with a bike power meter. This technology measures the watts put into the pedals, which is the important metric for efficient training. Team ZWATT sells aftermarket crank-based bike power meters directly to consumers (B2C) at great pricing with more features and top performance. Developed in Denmark. Manufactured in Germany/Latvia/China. SENSITIVUS sells the technology (B2B) to allow easy integration by crankset manufacturers. And owns the Team ZWATT brand. Our background Back in 2013, we started building bike power meters based on 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-gauge 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. Inspiration 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 surfaces 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. Team ZWATT 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 prices, 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.
