If you are familiar with Strava and the Kudos, you will understand the Kinos. The Kinos are a valuation of your effort based on the energy spent. Scientifically, it is equivalent to Kilo-joules (Wattage x time). We use Kinos as an incentive, adding some bonuses if you reach milestones and ride a video to the end.
We also believe the Kilo-joules calculation is more accurate than calories as calories really depend on anyone's metabolism.
