BKool AIR Direct Drive Smart Trainer. The trainer that caught my attention two years ago with a very unique and revolutionary design arrived in the Lama Lab a few weeks back and has been put to the test. It wasn’t smooth sailing from the beginning, having to work through a few issues with BKool direct in regards to rebooting and power accuracy. By all reports I’m not alone in this aspect – RoadCC had the exact same experience with their review. A solid design that’s let down by a few technical omissions.
