Stumbled across this while looking into a Zwift subscription. Specs look comparable or better than Zwift. Will be interesting to see if it has the same uptake otherwise it might be some lonely virtual cycling if it doesn't!
Will need to cancel before 31/12/2017 before the paid subscription starts in 2018 ($9.99 per month).

One cool feature is you can download strava route and get it converted to a 3d simulation and ride the route in Bkool app. Think that feature is still not supported in Zwift (?)
