Indoor Bike Trainers

If you are like us, a good bike ride can make your day.  Getting outside, exploring, and having some sun on your face are all part of what we define as a great ride.  One of the problems with cycling, though, is that when the weather gets bad, conditions can keep you off the road or trail.  That is where bike trainers come in.

Maybe it is raining or is too windy outside, or perhaps you need to avoid rush hour traffic or an unsafe dusk ride.  This is when you just mount your bike on to a bike trainer and get the exercise that you want, but at home.  In fact, if done correctly, workouts on a trainer can be some of the best workouts you get anywhere, and will help you stay on your tri training plan even when cold, rain, or darkness aren’t conducive to it.  If you have a plan for your 45 or 60 minutes of spinning, it can be just like going to a hard spin class.

Riding on a turbo trainer often gets a bad rap.  It can be boring, you don’t get the excitement of moving outdoors, and sometimes it is just nice to get out of the house.  But trainer workouts can be intense, and give you some of the best cardio work you get all year.  In fact, the NIH has found that after 12 weeks of high-intensity cycling training, a measurable improvement in overall cycling efficiency occurs in most cyclist.  Start your outdoor season off with a good indoor base, and you will be feeling good by the time you get to your first race.

The bottom line is that high-intensity interval bike training works, so if you are looking to get faster in your cycling, incorporating trainer workouts into your season is critical.

Bike Trainer Basics

Bike trainer spin class triathlon

Like a spin class in your own home.

A bike trainer is typically made up of a frame, a clamp with which the bike is held securely, a roller that is pressed up against the back wheel, and a mechanism (whichever sort it may be) that is used to provide resistance (the exception being a more expensive “direct-drive” version, described further below).  The bike you plan to use is mounted onto the trainer so you can experience a workout comparable to an outdoor ride, just in a highly-controlled environment.

The smart trainers, which are a higher-end version of the traditional bike trainers, are typically direct-drive (meaning you take your rear wheel off and just hook the bike right up to the trainer).  These require just a bit more research, so we did a piece on them here.

Some people use bike trainers for practice before triathlons or other cycling races, whereas others tend to use it as a substitute for riding outside if the weather is unfavorable.  Either way, a bike trainer can provide a high quality workout, and in many cases providers the rider with a more difficult and challenging ride, than riding outdoors.

What to Look for in a Bike Trainer

Today, there are a lot of turbo trainers or bike trainers in the market, each more fancy, well equipped or expensive than the other. To decide which one is best for you, keep the following in mind:

  1. Budget / Price. This one is a no-brainer. You obviously need to purchase something that you can accommodate within your budget, no matter how appealing a $900 bike trainer might seem to be.  The quality of your workout will more be determined by how hard you work than how much you spent on the trainer.
  2. Potential resistance. The “resistance” is the amount of power output — wattage — you are able to trainer before it maxes out.  If you are a beginner to biking, perhaps a more entry level bike trainer would be best for you. If you are training for more serious races and need precision in your efforts levels, then a more advanced bike trainer with a power meter might be worth the extra investment.  Most of us can’t get up to 1,000 watts of power, but if you are one of those who can get that high, some trainers might not be a match for you.
  3. Noise factor. Wind resistance trainers may be cheap, but can be much noisier. Similarly, fluid trainers are relatively less noisy but are far more expensive.  If you are working out in an
    bike trainer review

    Direct-drive trainers tend to be quieter to operate.

    apartment with two roommates, you might need to opt for quiet.  If you have a nice workout room that is relatively secluded, your options might be more.  Many bike trainers are now advertised with a decibel reading, so you can compare one against another.  If you go the smart trainer route, they have gotten way quieter over the past couple years.  Expect a new smart trainer to clock in at 60 decibels or less.

  4. Durability.  If you are going to be riding long distance or doing intense workouts, don’t skimp on the bike trainer.  As can be said with many types of workout gear, sometimes spending a little more on quality at first results in spending less in the long run.  We have used some well-made trainers for several years with virtually no maintenance required.  In cycling circles, it is often noted that the first thing to go is the fluid seal, and you get a fluid leak from a traditional trainer.  We haven’t had it happen to us, though, and have had good success with our Kinetic and CycleOps trainers.
  5. Compatibility with your Bike.  This is usually not going to be an issue with most road, tri, and even mountain bikes, but it is good to be sure that the trainer and your bike will work well together.  We would say that 90% of road and tri bikes will work well with the trainer — the only issue is if your frame design has some type of fancy feature, especially on rear-most part of your frame and the rear dropout area.  Note that some bike manufacturers say that you void the warranty if you break a carbon fiber frame while using a trainer.  We have used carbon fiber bikes on trainers for years with no problems — but it is something to keep in mind if you have an uber expensive bike, or if you are a much heavier-than-normal rider.  If you plan to use the trainer with any type of power meter, do a little checking to make sure they will work together.  They probably will, if both components have been made in the past 3 years.
  6. Technology.  For many years, a bike trainer was a pretty simple piece of equipment with a roller, a way to clamp in your bike, and not much else.  More and more, however, trainers and spinners are becoming “smart” much like everything else is (we did an entire piece on that, here). That means you can buy trainers with a built-in powermeter, or that can integrate with streamed workouts from paid online services.  Getting this technology will double your price, but for the right person it could be worth it.  This review is primarily about the standalone, non-smart trainers (but of course they can be used with streaming videos, they just don’t integrate the same way) although we did include the Wahoo Kickr which is in the smart lineup.  The world of smart trainers is so involved that we decided not to clutter this piece with all of that info, but be sure to check out our article devote to Smart Trainers and Apps.

All of these factors, including space to store the trainer, etc., play into your decision of buying a particular bike trainer.

4 Best Bike Trainers on the Market

Kinetic Rock and Roll Trainer

$$$ – moderately priced.   Find Here.  

kinetic rock and roll trainer best

Kinetic trainers.

Kinetic makes one of the most popular and high-quality bike trainers in the entire world. They have been making trainers in their distinctive green color since 1999.  Of course, the design has improved steadily since then, but they remain a go-to brand for anyone who wants the tried-and-true.

Bike trainer veterans claim that Kinetic is worth the money and the steep upfront cost that might seem daunting at first. Almost all of their trainers are acclaimed to be brilliant pieces of technology. Amongst their trainers is the Rock and Roll bike trainer that is by far one of the most sold and appreciated ones in the bike trainer industry.

What makes it so different from all the others is that it gives a more realistic ride than most other non-smart, “wheel-on” trainers. Even though a bike trainer is meant to keep the bike stationary, it is not as realistic as real riding. With this trainer, the bike can be swayed left to right exactly the way you would in an outdoor riding experience. Apart from this unique feature, the fluid resistance unit is one of the best in the market, and it slows even beginners to control and adjust resistance according to their needs.

If you are at this price point, you may want to consider a couple hundred more bucks on something like a Tacx Flux 2 — an affordable (relatively) smart trainer.  See more on the Flux 2 below.  However, if you are in the market for a classic-style trainer, this is a good one.

Though it is a significantly large trainer and is rather pricey for a non-smart trainer, the feel of the bike ride and the exceptional fluid resistance mechanism make this a must have for enthusiasts.  Find it here.

Saris Fluid2 Trainer

$$$ – moderately priced.  Find here. 

The Fluid2 is bulletproof, lasts a long time, and does its job. What more could you want?

Saris, the new branding name for the old CycleOps, is one of the leading bike trainer manufacturers in the world, with trainers being best sellers in the United States as well as being acclaimed by critics. One of their best sellers is the Saris Fluid2 Indoor Trainer, a model that garnered CycleOps a lot of respect, recognition, and revenue over the years.  We can speak from experience, the Fluid 2 works and lasts a long time.

The Saris Fluid2.

Though the price point may be a bit daunting at first, users claim that it is worth every penny you spend. This particular trainer features a state of the art fluid resistance mechanism that makes riding a bike on this trainer a very ‘road-like’ experience, and also allows for a lot less noise. For professional and avid cyclists, bike trainers are boring and fake because of how stationary and unrealistic the riding experience is. With this one, however, the trainer offers a road like an experience to make it far more real and a lot more interesting. This allows for better practice as well.

Buying this trainer as part of a kit will give you the climbing block for your front tire as well as a sweat mat to put under the bike.  The Saris works well with both road (or tri) and mountain bike designs, but by far the best setup is with a road bike outfitted with a slick or trainer rear tire.

It comes with a “smart-equipped” option, meaning that you have a speed sensor allowing you to connect to apps like Zwift and Rouvy.  Make no mistake, though, it is not a smart trainer.  But people have gotten many, many great years of quality training without going the full smart route.

The adjustable foot pads, the hydraulic fluid used in the resistance, and the well-made frame all contribute to an excellent riding experience.

The “smart-equipped” option is here, on Amazon.

The basic option is here on Amazon.

Minoura 760 Trainer

$$ – Less expensive.  Find here.  

Minoura is a Japanese brand of bike accessories (and refrigeration parts), and while it doesn’t have the same American-made name cache as Kinetic, CycleOps, or Saris, Minoura has actually been in existence as a company for over 80 years.  They obviously haven’t been making bike trainers the whole time.

Of their lineup, we like the 760 trainer.  It is a well-built trainer that is a few bucks less than our first two alternatives.  It is lighter and narrow as well, something that is good if you are in a pinch for space.  However, we think the narrower profile and lighter overall mass might make it a little less stable if you are someone who really rips up your frame on your hard spins.  But for a more casual rider, that difference might not be as noticeable.

The big advantage of this trainer is that it is magnetic, instead of fluid-based.  Some like the feel of a fluid-based trainer, but they are heavier and after a while sometimes leak (although leaking is not very common).  It creates lots of variation in pressure — a good thing — and it generally is a quiet unit.  This is something that is not the case with all magnetic trainers — some have a loud whine to them.  But not this one.

For those who want something a little lighter and more compact, and prefer the idea of a magnetic resistance over fluid-based, this would probably be our top choice.  Find here.

Tacx Flux 2

$$$$ – Expensive

If you are in the market for a smart trainer, we like the Tacx Flux 2 of this year’s crop as a great overall value.

Tacx Flux 2

A smart trainer is a game-changer, allowing you to seamlessly integrate with apps like Zwift and Trainerroad, among others.  It is a true, interactive experience, allowing you to constantly see your power stats, cadence, and feeling increasing and decreasing resistance as the workout or course changes.  In the case of Zwift, you can ride with friends or groups as well.

Saving the most expensive for last, this trainer is specifically for those who can justify spending nearly a thousand dollars on a bike trainer.  It falls into the category of smart trainers, where the going price starts at $600 and can go all the way up to $1,500 or more.  Considering the features that it comes with, the price tag can be justified.  This is a direct-drive trainer with smart technology, a couple game changers in one if you have never used one.

The direct-drive feature is nice because it removes the variability of tire pressure on the overall power transfer, and it also allows you to not worry about using a trainer tire while riding.  You literally just pop the rear wheel off, and hook your chain directly in to the unit while mounting on the trainer.  The smart features are intended for those who plan to use the unit with an a third-party app like Zwift.  A trainer like the Flux will fit perfectly into your overall Zwift setup and you will be smart-riding all winter long.

We have ridden all of the smart trainers out there — CycleOps, Saris, Wahoo, Tacx, etc.  Even Peloton.  Of the bunch, the Tacx is probably the quietest, but the high-end Tacx is quite expensive at nearly $1,500.  This model, the Flux 2, doesn’t have quite as large a flywheel as its big brother, but it will be plenty of power and responsiveness for 99% of riders out there.  The power ability maxes out at 2,000 watts, more than enough for anyone.  Most cyclists have a hard time ever hitting 1,000 watts, even for a few seconds.  A power meter by itself would normally cost $600 or more to put on your bike if you did it standalone, so using a smart trainer hits many birds with one stone.  On a smart trainer, you track power and other key output stats on any number of apps you can pair with the trainer.

The Flux 2 comes with firmware that automatically and simply connects to the app — not technical expertise is needed. And if you need a recommendation on an app, we like Zwift, Sufferfest, and Trainerroad.

This is a substantial investment, but worth it.    Find the Flux 2 here.

Should I Get a Smart Trainer?

We did an entire piece on smart trainers, here.

One of the most common questions we are getting now is if people should get a smart trainer or a regular trainer.  Our answer is usually the same: Make sure you get a good quality trainer of some sort, because even a non-smart trainer will do wonders do your indoor and offseason training and fitness.  From there, think about how important the community is to you, as well as how much you are already planning to spend.

If you are already going to spend $500 or more, consider just moving up to the smart trainer functionality so you have that ability if you want it.  If you are someone who really values riding as part of a virtual group or an interactive class, you will want the smart technology.  Otherwise, we can tell you that we have been happy for years — actually for a decade — with our regular trainer workouts coupled with the right workout videos for inspiration.

One important note – setting up a smart trainer is quite a bit more involved than a traditional trainer.  With a traditional trainer, you take it out of the box, stick your bike on the trainer, clamp it in, put your front wheel on a block, and go.  With a smart trainer, you are likely removing the wheel and maybe even the cartridge, putting a cartridge on the smart trainer, plugging everything in, and then syncing the trainer to whichever app you are using.  If you want something that is really easy to plug-and-play on a random rainy day, a traditional trainer might actually be more your speed.

For the record, besides the Tacx Flux 2 that we write about above, the other smart trainer we really love for the money is the Saris H3.  Check out our Saris H3 review, here.

Fluid vs. Magnetic Bike Trainers

fluid trainer bike

A fluid trainer actually houses fluid which creates the resistance.

There are two main types of trainer mechanics, fluid or magnetic.  This is the core of the trainer, and what provides the resistance for your workout.

In a fluid trainer, the “roller” on the trainer connects to an impeller that rotates through fluid, providing the resistance for your pedal stroke.  In a magnetic trainer, there is no fluid involved.  Rather, there is a magneto which you can manually adjust to the desired resistance level.

Fluid trainers are typically viewed as the better of the two, when it comes to traditional trainers.  It gives you a more road-like feel, and the fluid typically allows you to increase your workouts to a very intense level without maxing-out the resistance.  Today’s fluid trainers almost never leak, a problem in years long past.  Fluid trainers are also quieter.

Magnetic trainers are simpler, and because of that they are usually less expensive.  The downfall is that they often are limited in the range they can give you, creating less variance in your workout feel, and a higher likelihood that you could actually outgrow the resistance if you become a very good cyclist.  Note that most smart trainers are made with magnetic technology, but it is quite sophisticated and an entirely different category than basic magnetic trainers.

If you are buying a traditional bike trainer (not a wired, smart one), go with the fluid.

Other Trainer Accessories

bike trainer tire

A trainer tire can withstand the friction of a traditional trainer.

In addition to the trainer itself, you might want to consider a few other accessories.

  • Training videos. In our opinion, these are indispensable and the reason you get a trainer.  There are several series of Cycling DVDs out there that will help you get the most out of our workouts. Having a focused training session will turn your trainer session into a spin class.  Done right, these will be incredible workouts.  You can usually find ones that are anywhere from 30 minutes to more than 90 minutes long, and they can either be in DVD form or streamed to a device or TV.  We recommend having at least 5-6 to choose from, as your available time and desired intensity will vary from day to day.  Our favorites tend to be the Spinervals series.
  • Tire block. Many trainers will come with a front tire block, but some won’t, especially if you get one used.  A block is key, because without it the rear tire will sit much higher than the front.  If you have the option of a new trainer with a kit, always do the kit — that means it includes the block and other accessories.
  • A mat can be useful under your bike, especially if you are doing workouts that will cause you to sweat.  Most mats will run between $35 and $50, like these on Amazon.  The sweat, over time, can damage some floors if you don’t promptly wipe it up – and after an intense workout, trust us when we say wiping up a pool of sweat is not going to be top of mind.  Mats are not rocket science — just get one that will serve the purpose, and don’t overthink it.
  • Trainer tire.  The problem with using your bike on a trainer is that it can really wear out a tire.  The friction of a tire on the trainer creates a lot of heat,which reduces the life of the rubber on a typical road bike tire.  That is why we recommend using a trainer tire for about $35.   It can withstand the heat and friction created by a traditional bike trainer.
  • bike trainer wheel setup

    We like to have a spire rim, cassette, and tire at the ready for a fast swap when we want to go on the trainer.

    Spare rim, cassette, and skewer (optional).  We often just mount it on an old, used rim and swap the whole wheel out each time we move the unit on or off the trainer.  This makes it easy to do a 5-minute change if you see that the weather is bad, or change your mind and decide to run outside.  It is much simpler (and cleaner) than the 10-15 minute process of putting the right tire on your rim.

  • Fan.  Nothing fancy here, a basic old room or office fan is all you need.  When you are riding in a static position indoors, without the breeze hitting your face, you will get hot faster, sweat more, and need some type of relief.  A good fan situated a few feet away can fit the bill.  Nothing fancy needed, just a simple one is fine.  You probably have a spare tucked away in your closet.
  • Towel.  For the same reason you need a fan, have a supply of small towels ready for your rides.  You will sweat, and a towel will help you stay dry.  I like to lay mine over the stem and headset bolts on my bike so the sweat does not corrode them.

Conclusion

With the options being so different from each other, definitely do your research and be sure that your purchase fits your needs.  The four we listed above are all ones that we would stand behind.

A bike trainer, if used appropriately and regularly, can be worth every penny you spend.  After all, you are training on your exact bike, getting used to the saddle, angle, and all of its components, rather than having to get the feel for one bike in the summer and another in the winter.  If you are anything like us, you will get to the point where you crave some of your tough trainer workouts in the winter.
