Description

Find some alone time.

If we all had our druthers, we’d own multiple trainers — a lightweight one for travel, one that feels as smooth as the road for home use, and maybe a set of rollers, too. With the Kinetic Road Machine Fluid Trainer, you get the same smooth fluid resistance unit as featured on the Rock and Roll Trainer attached to a lighter, more compact frame. It’s the best of both worlds. 

The Road Resistance Unit is an impressive feat of engineering. It uses a 6.25-pound (2.84kg) flywheel and a completely sealed fluid resistance unit. Together, they give you a consistent road-like feel and resistance curve. The tire roller is made of stainless steel and is 2.5in (6.35cm) in diameter, which is a good bit larger than much of the competition. The larger roller means less wear on your tire and it reduces the temperature of the spinning elements.

The resistance unit is unique as it's made of two parts. The first is the driver made of a small flywheel embedded with six rare-earth magnets. The other half is a completely sealed cast-aluminum fluid chamber that is bolted to the housing containing the driver. The fluid chamber contains an impeller with corresponding magnets. As you ride, the magnets in the driver spin the impeller through medical-grade silicone fluid to provide the resistance. And since there is no driveshaft entering the fluid chamber, the Kinetic design eliminates a common design weakness of most fluid-resistance units.

As expected, the system builds heat in the form of friction. However, the fluid acts as a coolant and the chamber has 80 cooling fins on the outside that act like radiator fins. It's impossible to overheat the chamber or reach a point where performance is diminished. The silicone fluid retains its physical properties, even up to the normal operating temperature of 325degrees Fahrenheit when riding 25mph.

There are several benefits to this system. Because it doesn't overheat, the viscosity of the fluid doesn't change, and that results in a consistent road-like power curve that increases as your speed increases. Kinetic published a chart to show exactly what speed goes with how many watts. To give you an example, it takes 143w to ride at 15mph, 258w at 20mph, and 25mph will take 430 watts.

For the Road Machine Fluid Trainer, the Road Resistance Unit is attached to a more traditional triangular base. The base is 32in (81.28cm) wide when open. The bike is attached to the trainer via two threaded knobs, with a locking quick release on the right side. When folded flat it is 26in (66.04cm) wide and 6in (15.24cm) tall, a good bit smaller than the packed size of the Rock and Roll Trainer, and it weighs about 20lbs less. It works with wheels from 22in to 29in in diameter.

The Kinetic Road Machine 2.0 Fluid Trainer is green and comes with its own quick release skewer that assures a good fit in the cone-shaped cups that secure your bike to the trainer. Like all Kinetic trainers, it comes with an unconditional lifetime warranty. A bike computer, that shows power as you're riding the unit, is sold separately.

Fantastic fluid trainer

  • Familiarity: I've put it through the wringer

Purchased the KK Fluid 2 trainer to keep my cycling fitness up through the winter and to be able to ride on summer days if it's raining or too windy (for example we had 85 mph winds here yesterday). Prior to this purchase I borrowed 2 different trainers from friends: 1) A magnetic trainer, which was not enjoyable to use at all. 2) Cycleops Fluid2 Trainer, which was nice and convinced me I wanted a Fluid trainer, but did not seem very durable and I did not care for the way you secured and removed the bike from the trainer.

I went for the KK trainer because it was more stout and the online reviews raved about this model. I can concur that the KK Fluid 2 is very stout and easy to mount your bike onto and quickly remove. I also purchased the riser block and mat and went to the extent of purchasing a cheap rear wheel and trainer specific tire so I'm not using my good wheels or wearing out good tires.

This trainer is IMO quiet, provides a near road like feel, and is very sturdy even when I'm up out of the saddle cranking away. I've used it for almost a year now and cannot find any faults with it.

Good Machine

  • Familiarity: I've used it several times

The ride is smooth and relatively quite. You don't need to max out the volume on the tv or with headphones. It is still a little loud for the neighbors below if you are in an apartment. It also has a really nice feel to it when riding. I would be interested in trying the larger flywheel to see how it changes the feel of riding.
