Rock those winter miles.

One of the common complaints levelled against indoor trainers is a lack of real-world road feel that can leave riders feeling off-kilter when they remount their steed and hit the roads in the spring. Kinetic answers that complaint with the Kinetic Fluid Trainer Rock 'N Roll Smart with InRide Sensor, boasting a resistance unit and frame designed to mimic the natural movement of riding out on the road. This version adds inRide sensor technology, letting you smoothly crank out the miles with a plethora of data tracking and workout planning options.

Kinetic's Road Resistance Unit is a revolutionary piece of engineering. The 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 a reduction in the temperature of the spinning elements. The right side has a 6.25lb (2.84kg) flywheel, the heaviest around, and gives the satisfying feeling of momentum when you're spinning up to speed, holding speed, and slowing down. On the left side is a unique two-part resistance unit, which is the heart of their system.

Of course, this system builds heat as you ride — your energy has to go somewhere (in this case 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 325 degrees Fahrenheit when riding at 25mph, resulting in a consistent road-like power curve that increases as your speed increases. To give you an example, it takes 143w to ride at 15mph, 258w at 20mph, and 25mph will take 430w.

The Rock and Roll Trainer doesn't have the traditional dual-triangle frame found on most stationary trainers because they want the bike to be free to sway and bob to more closely mimic how a bike behaves outdoors. Kinetic builds the Rock and Roll's frame with a wide footprint on the bottom for stability, and then mounts the resistance unit and support legs for the bike atop a beefy set of plates that sandwich two sets of two elastomers. This spring-loaded arrangement allows the bike to sway laterally and bob up and down a bit, just like you'd feel on the road. Kinetic recommends pairing this trainer with its separately sold Turntable Riser Ring, which holds your front wheel on a lazy Susan-type turntable so it can turn or sway.

Kinetic pairs the Rock and Roll with its inRide sensor technology, which allows the trainer to connect to your favorite device via Bluetooth Smart functionality to track your ride without any additional sensors. The inRide app not only lets you see ride data and metrics, but also features built-in workouts, individualized target zones, and the ability to upload ride data for analysis.

The Kinetic Fluid Trainer Rock 'N Roll Smart with InRide Sensor is compatible with wheels ranging from 22 to 29in and folds flat for convenient storage. It comes packaged with its own quick release skewer that ensures a good fit in the cone-shaped cups that secure your bike to the trainer.

Pretty cool

  • Familiarity: I've used it several times

For the last 2 months, I used the trainer at least 3 times a week, and works very well. Actually, all you can read related to this product it is true.

The inRide feature is pretty cool. I have an iPhone SE and it paired instantly with the trainer via Bluetooth.

Overall I'm very satisfied, but, I can't give it 5 stars, because, Riser Ring isn't included, come on Kinetic, you can do better!

Nice trainer

  • Familiarity: I've used it once or twice and have initial impressions

First ride was yesterday for 3 hrs. First thing you notice is that it is not as abusive to you sit bones as other trainers. There is up and down compliance as well as side to side. No noticeable bounce at normal rmp (I'm 170 lbs, usually ride 70-100 rpm). I think I could do an indoor century on this. I tried fast pedal (very low resistance, see how fast you can pedal for 3 minutes) it does bounce above about 110 rpm with my sloppy pedal stroke. Out of the saddle ridding takes some getting used to. I do have the turntable riser under the front wheel. The inRide feature is interesting. I have an Android phone running 4.4.2 and it paired instantly with the trainer via Bluetooth. It even makes an estimate of cadence even though there is no cadence sensor. It must be estimating cadence from the rise and fall of rotation rate of the trainer roller because that is the only thing it is measuring. It also estimates power from speed. Only down side is that I don't have a Bluetooth heart rate monitor (HRM), mine is ANT+ which this won't connect with even though my Android phone does work with ANT+. Looks like the Wahoo Tickr HRM is the way to go as it works with both Bluetooth and ANT+. I've read that the Kinetic HRM is just the Wahoo HRM with a Kinetic logo. I don't know if the Kinetic HRM works with both Bluetooth and ANT+.

First impression: I like it.

This is a follow up on my original review. The latest version of Kinetic / inRide software for Android paired with my phone once in about 50 tries. The software is definitely getting worse.
