I use a crossbike (http://www.konaworld.com/jake_the_snake.cfm) on a bike trainer (https://www.amazon.com/Kinetic-Road-Machine-Fluid-Trainer/dp/B01KHE5B4S) and have the chain on the largest front ring and the smallest one on the back, but the resistance felt too low. What I can do to increase the load?
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.
I have a CycleOps fluid 2, and I'm assuming yours works similarly since they are both fluid trainers. Fluid trainers don't have adjustable resistance. If you want the resistance to be harder, shift the bike into a harder gear. The resistance will increase as your wheel spins faster. It looks like your bike has a 46 front chaining and an 11 tooth sprocket in the back as your hardest gear. This should be plenty of resistance, again, assuming it has similar resistance to my trainer. I usually have mine on the middle chain ring on the front which in my case is 42 teeth. I don't usually make it anywhere close to the smaller cogs.
Next time your at the supermarket go to the home goods section and get a pack of those felt pads for furniture legs. Cut 2 pieces the size of your brake pads, open your rear brakes and place one under each pad (sticky side toward the pad). If you have a normal set of brake levers you'll be able to adj. the braking or you can put something between you brake cable and frame and adjust it hat way also. Just having the felt in there is enough to cause to drop into a lower gear. You'll be able to adj. it so you can get up off the seat and crank hard. Simple. Your welcome.Peleton shmelaton.
