In reply to Bjartur i Sumarhus:
Firstly, is it a Pro or a Trainer model? Most of the gyms will use trainer as it's aimed at novice or leisure riders, not experienced cyclists. The default resistance is much lower, so to get into your power zones, you'll have to spin like crazy.
Assuming it's a Pro (which I have), then it's all about the fan. I rarely use the magnet - it's supposed to mimic hill climbs, but I tend to use it on a free training session, rather than structured Wattbike or Trainerroad package.
It does a take a while to dial in our power to cadence. I can now set my fan to my required power, at my required cadence without thinking - you do tune into it.
I'd give it some more time - just to find the cadence/ power sweet spots. and check if it's a Pro or not.
