what would happen if the working fluid was water instead of silicone? ignoring corrosion effects in the chamber, just looking at thermodynamic and mechanical effects for now.
@AaL3XaNd3R09 dude you have no idea how right you are!! i have the same problem! i swear after a while ive gone around and started telling my family and friends about my idea and to watch out for them because they will see one of my ideas on tv or the paper someday because like you i always run into people who have the money and have already invented my idea!
What I don't understand is how having a lower rpm in the resistance mechanism (due to the larger roller) leads to less heat being created? Surely, for the same power input (same workout) the same amount of energy has to be dissipated in the form of heat?
I could understand if there is a larger volume of fluid in the device, the temperature would not be as high, but this is not stated in the video. Please could you clarify how this works?
@MrEngelchen The rate at which thermal energy is being evolved is (apparently, according to their marketing) less than the rate at which heat is dissipated by that heatsink. If the roller was smaller, the thing will spin faster in the fluid so there'll be more heat while the ability of the heatsink to piss that heat off is the same.
My guess anyway. That stuff about silicone being medical hoorah sounds a bit bs'ey though.
@MrEngelchen I think it is just marketing BS for the most part. If it was smaller diameter it would create more resistance at a given tire RPM. The spool diameter was probably chosen to give the most realistic resistance for a given speed so that it is roughly like riding on a windless day on level ground.
@KineticbyKurt Yes, what I was getting at is that the engineers designed the resistance unit and then sized the roller to match the ideal resistance unit RPM for a given tire speed. The resistance unit is a pretty complex part so it is easier to modify the resistance profile simply by changing the spool circumference.

didn't exactly INVENT the magnetic drive as this has been used in water pumps for years!!

This review sold me on the product. Good to see the unique engineering.

@oisiaa smaller diameter rollers slip more too. The tire contact point is increased with a larger roller.

I am getting this for my birthday! Woop! Thanks for the informational video as to how it works.
