After our 2 July Kickstarter update, in which we announced that the first version of Stryd will support heart rate in addition to power, a few people asked whether the power number is based on heart rate. The answer is "no". Stryd determines power independently of heart rate, based on your body's motion and the slope of the ground.

Building the Stryd hardware
It's getting hot and humid for our engineers – in Boulder? No. In Shenzhen, a city in southern China, where the Stryd hardware is being manufactured.
Shenzhen is an amazing city: a global electronics manufacturing hub. Every day, millions of electronics products are made there and distributed around the world. Stryd engineers and co-founders, Jamie and Kun, have been living in Shenzhen for over a month. They spend their days working with over ten different partners helping us produce different parts of the Stryd hardware, and their nights synchronizing with our Boulder headquarters. Their work is paying off: the first testing batch of Stryd devices has been manufactured and is undergoing FCC and CE wireless communication tests.
