This actually has fewer features than the original Air Hub. Instead of Bluetooth or Ant+ connectivity and relying on a power meter and your smartphone it simply has a toggle switch between Off, 1, and 2. Mode 1 adds 1 watt for every 1km/h, and Mode 2 adds 2 watts for every 2km/h. Price has come down from the original version. About $1,000. That's still pricey for what it is but I like the idea for those who choose to train on a bike trail or who would like to get a workout in while riding a bike with a family member or significant other that doesn't have the engine to go more than 10-15mph.
