How to add resistance to my bike trainer?
This is the powercurve for the Cyclops 2 fluid trainer



You can see that at 30mph on the trainer you'll need to be producing around 400 watts. Using this website

46x11 will give you 30mph at 90 rpm (which is a reasonable rpm for home training). 400 watts is like a Pro climbing l'Alpe d'Huez. Note also that the power curve is exponential, every extra mph gets progressively harder. At 35mph you are in the 600-700 watt range.

Fluid trainers take a while to warm up - 5 to 15 minutes but generally offer more resistance while they do.

So I agree with the other posters, your unit is faulty in some way. If not, you should contact a Pro team for a contract.
