When it comes to buying a bike trainer, there are few who would disagree that a fluid bike trainer is generally acknowledged as the best choice when it comes to bicycle trainers. However, for all of the pros to a fluid trainer there is still a big CON and that is that they are very prone to leaking.

For years, the very well known and well respected Cycleops Fluid Trainer has dominated the market despite the real possibility that they might occasionally spring a leak. Cycleops customer service is second to none and they will quickly and cheerfully warranty your trainer for you but that can still be an inconvenience. It doesn't happen often but it still isn't appealing if you like no hassle equipment that just works. Kurt Kinetic Fluid trainers feature a revolutionary design that might just be the answer to your fluid trainer needs. Let's discuss why.

Destined To Fail?

Kurt's outstanding fluid resistance unit assembled on the trainer.

Don't get me wrong, the large majority of fluid trainer owners, be it Cycleops or another brand, are quite happy with those trainers and they don't leak. If you read many reviews or talk to many long term owners of a typical fluid trainer owner though, you will find that it certainly isn't uncommon for them to fail and leak oil out all over the place. The manufacturer may replace or repair the trainer happily and eagerly but who has time for that stuff. Not most of us, that's for sure.

The "new Sheriff" in town is my personal favorite bike trainer of all and that is the Kurt Kinetic fluid trainer. Why is this my favorite? What makes it so great you might ask? Not only does the design not allow this trainer to be able to leak but it's also simply an excellent trainer, quiet and a great feel that closely simulates real road riding.

You can see the seal that the shaft has to penetrate through. Over time, this seal tends to fail due to the heat involved and begins leaking. The kinetic design has no seal to fail.

An ordinary fluid bike trainer generates its resistance by powering an impeller through silicone fluid. This action will of course generate a significant amount of heat and can get as hot as 400 degrees Fahrenheit. This is where the leakage problem occurs, most fluid trainers use a shaft that drives the impeller which penetrates into the fluid chamber and utilizes a rubber seal to keep the shaft sealed and the fluid from leaking out. Any time you have a moving part and a lot of heat, you will get a failure eventually. It's just bound to happen with this type of design, it happens on cars, trucks, bicycles and bike trainers.

The Kurt Kinetic Fluid Trainer is designed quite differently. The fluid chamber is sealed in glass and the shaft does not penetrate through it. Magnetized wheels connect the impeller to the driveshaft and the shaft never actually penetrates the fluid chamber and there is no seal to leak...ever. This might sound difficult to understand but the easiest way to explain it is to show you. Check out this video discussing the Kurt Kinetic Rock and Roll fluid trainer and wait til the end of the video where they show you the internal workings of the Kurt Kinetic Fluid Trainer.

Kurt Kinetic Video Review

If you watch this video all the way through, it really highlights the way the Kurt Kinetic is designed and WHY it is so much better of a design than a typical fluid trainer. The chambered design combined with the magnetic coupling rather than a shaft is simply super cool and ultra dependable.

As you can see in the video, your tire drives the shaft which is connected to one rotating disc that has 6 powerful magnets on the face of it. This disc butts up against another disc that is located inside the fluid chamber. The chamber is sealed completely and the two rotating discs are coupled through the seal and simply will not allow this trainer to leak.

I am a very satisfied owner of a Kurt Kinetic Trainer and can attest that not only will it not leak but the design also affords a very realistic road feel and ride and is simple the best bike trainer on the market in my opinion. The warranty department at Kurt Kinetic will be like the Maytag repair man...nothing to do and plenty of time on their hands.

The Kurt Kinetic comes in a couple of incarnations that while similar, are all somewhat different than the others, so check each of these out and see which Kurt Kinetic trainer would be best for your needs.

Kurt Kinetic Pro Model Trainer

Overall Rating:

Retail Price: Varies based on product options

Amazon Price: View Sale Price

The Kurt Kinetic Pro Model Bike Trainer is an upgrade to the standard Road machine, not because it is any better but simply because it includes a few extra parts. Specifically the Pro model Kurt Kinetic is equipped with the standard 6lb flywheel that the normal Road Machine features but also includes an extra 12lb. flywheel that is designed for endurance workouts like tempo and base building Long Slow Distance rides. Packaged with a rock solid and stable 540 square inch base, the Kurt Kinetic Pro model trainer will keep you very stable and focused on the trainer, allowing you to concentrate on the task at hand. An excellent choice and more versatility than the Road Machine IF you are into specific types of training. If you are just looking to stay in shape, then the Road Machine will work fine.

Kurt Kinetic Rock and Roll Trainer

Kinetic Rock 'n Roll Trainer with Road Resistance Unit

Overall Rating:

Retail Price: $560.00

Amazon Price: $399.00

The Kurt Kinetic Rock and Roll trainer redefines what "realism" means when talking about your workout as it is the ONLY bike trainer on the market that delivers a very natural side-to-side (rocking) motion that emulates real road riding. This unique lateral motion simulates the out of the saddle grinds and will engage core muscles that maintain balance and don't typically get engaged on a normal stationary cycling workout. What this means is that you can now work on both your riding technique and your power for those out of the saddle intervals. The Kurt Kinetic Rock and Roll Bicycle trainer will redefine what your expectations are of an indoor bike trainer and is the closest thing you can get to a real bike feel without transitioning to rollers. If you are used to having the best equipment around, then the Kurt Kinetic Rock and Roll Bike trainer is right there. An excellent indoor bike trainer.
