Pam Sayler, Kinetic by Kurt National Sales Manager, discusses the reasons why the Kinetic Fluid Resistance unit is the best on the indoor-trainer market.
Here it’s November 2019 and I’ve just purchased what’s now known as the Kinetic Road Machine 2.0. These are the best trainers for the money. The best customer service and warranty in the industry hands down. Just my .02.
I am going on my 2nd "indoor" season with the rock n roll trainer. So glad I purchased this product. My fitness level stays up during cold midwest winters and come spring I am ready to rock and roll :)
As a mechanical Engineer I like to do my research when purchasing a product. With the possible exception of my Giant Stance 29-2 XL I haven't been THIS excited about a piece of gear in a very long time ! Can't wait for my Kinetic Road Machine Smart 2 Bike Trainer to arrive ....
@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.
Anyone ever overheated to the point the feel of the resistance changes and the KK power reading on the their computer starts to change? Have to hold around 400 watts for this to happen.
Interesting video. 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?
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.
Hi Geoff, thanks for asking. Our tire-drive trainers will work with a wide range of tires and wheel sizes. We have solutions for mounting 20" bicycles up to 29" x 2.2 tires. www.kurtkinetic.com/tech-info
Yes, there is something I don't understand. how is the word neodymium pronounced ne-o-dy-min-i-um. Where does the extra syllable come from?..... *shrug* can you please verify my input?
@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.
I believe the company has now been sold to someone else. I did not get any response from my inquiry about the road machine failing. The cadence is way low and the wattage is 10 to 20 W low now.
Kinetic quietly sold their company shell and branding to Magene, where it now basically sells Magene trainers under the Kinetic name (there are no longer production/etc facilities in the US)
The more serious a rider is about his/her training, the more important the small stuff. Not all of us want some kind of POS that certainly works, but doesn't offer the best ride... The magnetic couple: VERY big deal. The alternating poles of the magnets to avoid slipping: YOU try doing serious intervals on a trainer that slips whenever you accelerate a little too fast.... The thermodynamically neutral fluid: YOU try a trainer that is inconsistent. What exactly is "really no big deal?"
It might even help with tire noise, the larger diameter, I would think... Less pressure needed against the tire. Less heat on the tire as well... Again, not marketing BS. Just things that you don't think about before opening your condescending, self assured mouth. ;-)
Roller size is an important factor... Not marketing BS. And since the resistance can be adjusted by the inside of the fluid chamber and impeller, roller size really has next to nothing to do with setting the resistance design-wise... It's about other things.

Again, a video without any riding. I do not want someone explaining the thing, as much as I want to see them using it, and most of all……HEARING IT WITH A DECIBEL METER.

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

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

That's why I have one! It's the best fluid resistance unit made.
Good video explaining the engineering.
Good video, direct rollers has the same mechanics?

Doyou have spare part provide if it leak?
Interesting video.

Ask Bill Nye

hi what size tire ranges can these fluid trainers be used with?

The plastic part on mine broke ☹️
What is the silicone oil viscosity in your product?
Eu também estou procurando o tipo de óleo.
Will the magnets gradually loose power and increase slippage?
My ones haven’t

what is ''medical grade'' silicone? it sounds badass though....
MrBirdshell666
Think breast implants
It's medical grade silicone. Boob implant gel dude.
guarantee it won't leak? what if the bearings goes bad inside the unit? what part of this unit is not lifetime guaranteed?

i love how she talks up literall every part of this. even the stuff thats really no big deal

Yup, that's what they are.... *shrug*
Is there something you don't understand about that class of magnet or something?
LOL "neodyminium rare earth magnets"
It's "Thermodynamics" not "Thermal dynamics".
"the best indoor ride you can buy..."
heh.
heh heh ...
eheheheheheheehehehehehehehehehehheheeh

+Robert King seriously haha can't find anything on the noise levels!
