11 Best Smart Trainers for Zwift (Updated 2023)

If you’re someone who’s shunning outdoor biking in favor of cycling within the virtual world using Zwift, then you’ve come to the right place. Cycling based on real-world intervals may not be enough for you. So, this is exactly why manufacturers have brought in smart turbo trainers to serve you throughout the year, in the comfort of your home.

Due to the ongoing coronavirus pandemic, it can be years before normal proceedings resume, until then, cycling indoors seems like an effective way of retaining top fitness levels. A productive application like Zwift will undoubtedly make your indoor cycling experience enjoyable and worthwhile.

Zwift can help in translating your real-world cycling efforts virtually. Also, the power that you generate in watts should propel you along a virtual landscape. Similar to the real world, the speed of your cycling can easily be adjusted, based on the road gradient, your height, and weight.

Buying Guide for Zwift compatible Smart Trainers

The features that you should be looking for while buying a smart trainer for setting up a Zwift application are as follows:

1. Flywheel

A precision-balanced flywheel should help you to attain a road cycling feeling, precisely due to the amount of kinetic energy they are capable of storing & also due to the resultant inertia they are capable of providing. Therefore, this will make you feel as though you’re coasting on a real road. There are some riders, who think and feel that the heavier the flywheel, the better would your cycling experience be. However, that necessarily isn’t the case. Design, construction, and materials all play a significant role in ensuring that you have a good cycling experience. There are some brands of trainers that also use virtual flywheel as well. Such as the Garmin TacX Neo 2T trainer consisting of magnets. Although, you’ll be required to pay more for the trainers that have a virtual flywheel. The major advantage of using a trainer with a virtual flywheel is, these are capable of changing the inertia, based on the virtual terrain that you choose. Therefore, you’ll feel that climbing feels a lot different to that of training on a flat surface.

2. Weight & Packability

You will find that smart trainers come in a variety of shapes and sizes. They also have different weights. Out of all categories of smart trainers, wheel-on trainers are more likely to be the lightest, you’ll also be able to transport these trainers with relative ease as well. On the other hand, direct trainers are comparatively bulkier. Although, their sizes & shapes may vary quite a bit. You’ll be able to fold some models of these trainers with relative ease. Nonetheless, they will be quite heavy, either way.

3. Power & Gradient:

Different models of trainers feature varying maximum power capacity. This corresponds to the total amount of resistance they are capable of generating. This value may range between 1500 watts to more than 3500 watts. Although, a model of a trainer that offers 2000 watts should be sufficient for you, provided that you’re not a professional sprinter. The gradient can be defined as the maximum incline level that one of the trainers can simulate. This value is represented in percentages. You should keep in mind, a lower value of gradient wouldn’t necessarily hamper training sessions.

4. Noise:

Previously trainers used to be very noisy. However, nowadays there have been a lot of improvements in the noise levels, in the last few years or so. But you’ll still find that on-wheel trainers are comparatively louder than that direct-drive trainers. Out of all categories of trainers, direct-drive are the ones that are the quietest. Some models tend to be so quiet that the only sound you’ll be hearing is the sound of your bike’s drivetrain. If you plan on carrying out your session without disturbing anyone else inside the household, then you should get a direct drive trainer.

Figure: Noise Comparisons

Provided that your smart trainer tends to make a significant amount of noise, then the video below will be quite useful to solve that problem.

5. Other accessories

You’ll be required to plug a smart trainer into an electricity supply for the trainer to function properly. Therefore, you should get yourself a good quality extension-lead. It also depends on where you plan on setting up your trainer. This is because supplied plugs do not necessarily have long wires. You can use Bluetooth for connecting all your accessories/hardware. However, there are ANT+ accessories then you might use that for connecting. Although, in such a case, you’ll need to buy an ANT+ dongle as well, either for your smart device or laptop. Moreover, you should get a riser-block for your bike’s front-end wheel as well. Although, this will depend on the model of bike you’re using. Getting yourself a trainer mat is essential as well. It would be advisable that you get a rubberized one. Because this will help in soaking in the sweat and dampen the vibrations from your rides. Furthermore, the noise levels will be kept at bay. A sweat net can come in very handy as well. This will help in protecting your bike’s top-tube, stem & steer-tube Also, this will protect from corrosion & sweat. Do not forget to get a fan, one that is approximately 20” tall. Lastly, if you use either a tablet or a laptop, then get a stand that will help in positioning it right in front of you.

6. Internet

You must have a stable internet connection. It can be 4G, but keep in mind that during the 1-hour session, approximately 300 MB of data was used. You can also use an ethernet cable into the room where you set up the trainer. Although for this to work, you’ll need either another router or a booster for WiFi. Make sure that the internet connection doesn’t drop. Because this can be quite bothersome.

7. Zwift compatible device

You’ll be needing a smart device, such as a tablet, smartphone, or laptop. However, a smartphone screen might be smaller for you to read the data. Therefore, it is better than you use either a laptop, desktop, or tablet instead. Lastly, you’ll need to have access to the Zwift application on these devices.

8. ANT+and/or Bluetooth

Provided that your smart trainer, speed or power sensors are only compatible with ANT+ sensors, then you’ll need to buy an ANT+ dongle as well. It would be more convenient for you to use Bluetooth instead. Because you won’t have to buy an additional ANT+ dongle in this case.

9. Fan/Cooling system

You should get a bigger sized fan as well. This will help in keeping you aerated once you start sweating during your exercise sessions.

We’ve specifically bought this trainer last winter, to stay in shape. The assembly process is quite straightforward, the instructions within the Wahoo application is simple and easy to understand. Also, the process of assembling the sprocket (doesn’t come with the packaging) set has been described well. We installed Wahoo’s application and paired it with Bluetooth. Necessary software updates are also carried out by connecting the application with Bluetooth. Once we were done executing the spin-down test, its performance parameters were clearly displayed on our smart device. We aimed to use the Zwift training application for having an efficient training session. Therefore, we proceeded with installing Zwift on our Windows 10 laptop. However, you need to keep in mind that, if you’re a Windows user, more specifically use Windows 10, then an ANT+ dongle is required for successfully pairing the Zwift training application with Bluetooth. This is the only obstacle that we faced while using the Kickr Core trainer, during 1 year of usage. We are hugely satisfied with the performance of the Wahoo Kickr Core smart trainer after integrating the Zwift application.

• Noise Levels: This trainer will offer you comparatively quiet performances. According to the scale, Saris’s H3 measures at 59 decibels at speeds of 20 mph. We’ve tested out this trainer within a soundproof area and the measurement that we precisely got was 58.92 decibels.
• Riding Feel: The H3 is equipped with a flywheel that weighs 20 lbs. You’ll have really comfortable riding sessions. The flywheel coasts for a significant amount of time.
• Power Accuracy: As we tested out this trainer, it happened to maintain accuracies that were claimed by the manufacturer during the vast majority of the time. Sprints happened to be within the admissible range.
• ERG Mode: We use the ERG & spin modes regularly while using this trainer. The ERG mode happens to be quite responsive. Moreover, this trainer responded very well with smaller chainrings & for lower speeds of a flywheel.
• Accuracy: According to Saris, the H3 should have accuracies between +/-2%. We found that the H3 indeed came within this range.
• Cadence: The reported value of cadence for the H3 was within 1 to 3 rpm. However, there were dropouts as we varied the cadence. Moreover, the H3 can broadcast cadence over wireless mediums such as ANT+ FE-C & Bluetooth FTMS. An estimate is made by taking the help of a combination between the flywheel speed & power.

The reason we bought the CycleOps H3 was that I wanted to shed some pounds. I must say it did not disappoint. We bought a sprocket for the rear-end wheel. This helped us to easily switch to the road-bike, in one piece again. Moreover, we used the Zwift application with this smart trainer on my Windows 10 compatible laptop. Also, using my iPhone compatible application, I connected this trainer to my television, all these devices being in our WiFi network. We controlled the software using the iPhone that I strapped into my bike. Once the free trial limit was over, we subscribed to these applications. Later on, we decided to switch to the RGT cycling application as it happens to be completely free. This application worked really well. It connected seamlessly to my iPhone, iPad & laptop as well. When running this application on our laptop we used an HDMI cable. The RGT may not contain all the scenery similar to the Zwift. However, it still does the necessary job quite well. But we’ve seen people winning virtual races without putting in a sweat, they simply breezed past us. This is something we do not think is possible in real life.

We wanted to get ourselves a smart trainer that offered a fluid resistance mechanism. After researching for a few months, we finally settled for the CycleOps Fluid². It’s been more than 6 months since we’ve been using this smart trainer and we’re satisfied with its performance. Setting up this was quite easy. We used applications such as the TrainerRoad & Zwift and it must be said that we’ve got a realistic and effective cycling experience while being indoor. This has been beneficial since we haven’t been able to go for outdoor sessions regularly due to COVID.
Some of the accessories that we bought while setting up this trainer are as follows:

1. Block for the front-end wheel.
2. We set up a cooler on one side of the room.
3. A mat for safeguarding the floor & preventing it from being drenched in sweat.
4. Cadence & Speed Sensors – For more effective workout sessions.
5. An application such as Zwift for serving us with a realistic virtual cycling experience.
6. As we used our personal desktop, we also bought a USB extension cord along with an ANT+ dongle.

Once we’ve set everything, then we tried out the Zwift application. It helped us to get a very realistic outdoor cycling experience that too in the comfort of our home. We were thoroughly impressed with Zwift so, once the 1-week free trial was over, then we decided to subscribe to it.

We bought the Thinkrider X7, a direct drive smart last April, during COVID, to be specific. We did not have any issues while setting up this trainer, the process was quite straightforward. Moreover, it integrated with the Zwift application effortlessly. It also served us with surprisingly quiet performances. As we got out of the bike’s seat, this trainer oscillated somewhat. This also surprisingly gave us a somewhat pleasant feel. If you pair an iOS compatible device with this trainer, then updating to the newest firmware should not be an issue. However, the same cannot be said for other platforms. If you’re someone who doesn’t tweak the smartphone applications too much, then this should be a good choice of direct drive based smart trainer for you.

We already have a magnetic-based trainer and have been using it for more than 3 years now. After having researched for months for some of the best smart trainers out there, we decided to buy the Elite Suito. It took me about 3 months to fully master the art of using this smart drive trainer. So far the experience of using this trainer has been totally different from the magnetic-based trainer. The fact that it has the capability of imitating hill climbs has been hugely helpful for us. My E-Training application came with a year’s free subscription. Videos with the application might have been better. So, I decided to sign up for the Zwift application instead and the realistic outdoor riding experience we obtained while using this application has been a breath of fresh air. In fact, this trainer seemed to be working quite well with Zwift. Once we reached a 9° incline, we felt it instantly. One of the best things about this trainer is, we were able to use it, straight out of the box. It also provided reasonable stability during our riding sessions. So far we never felt like we’d fall over, even during intense workout sessions. The packaging included a cassette and a holder for the front-end wheel. Our workout sessions were effective thanks to the hill simulation and the realistic riding experience while using the Zwift application. We’ve been totally satisfied with the performance of this smart trainer.

We’ve been planning on transitioning from a fluid resistance based trainer to a direct drive based smart trainer. Also, we used this fluid resistance based trainer for more than 6 years. The research was carried out for approximately 6 to 8 weeks. After thinking about it long and hard we settled for the Saris CycleOps Hammer(1st Gen.). The fact that the price of this trainer dropped significantly while we bought it made the deal even sweeter. From the very beginning, we started using the Zwift application and it was a thoroughly enjoyable experience. We’d recommend you to buy a crank sensor as well. This is significantly more effective compared to the calculated crank RPM. Setting up this trainer was quite easy, it took us approximately 15 minutes tops. We simply just got ourselves locked in and started pedaling. It wasn’t required for us to change gear to power up. Furthermore, this is much quieter than our wheel-on bike trainer. We were able to use the bike without needing to use a power meter. This trainer keeps cadence as well. Once we took the trainer out of the box, it was already installed with the latest version of the firmware. Overall, the Hammer, as the name suggests, is built like a tank. It’ll offer you good stability. However, make sure to be careful when you move this trainer, post-workout sessions. Because at 46 lbs, this is quite heavy. Lastly, we did not face any unwanted power drops either. It offered us good value for money.

After researching for months, we finally chose the Kinetic Rock and Roll Smart 2 fluid resistance trainer. Having used this trainer for over a year now, the thing that we liked most about this trainer is that it comes with integrated inRide Smart 3 sensors. We used the Zwift application for having an effective virtual cycling session. Additionally, stats such as power, speed & cadence were shown directly on the Zwift application as well. During our rides, we noticed that there were slight movements. We found this to be rather natural compared to fixed bike trainers. However, we needed some time for getting a hang of this, so that we could stay properly positioned within our bike. Overall, this trainer is pretty well constructed.

As this is a wheel-on fluid magnetic-based trainer, so, here are some of the things that you should keep in mind. Else, you may end up feeling uncomfortable during your rides.

• Make sure to have tires specifically allocated for your training sessions. If your bike isn’t a road bike, then get off-road tires for it.
• You should remember to loosen the bolts on your bike’s wheel once you’re done riding.
• Don’t forget to check for the pressure on your bike’s tires.
• You should always clean your bike’s tires before you start riding.
• Lastly, you can use the kinetic mobile-based application to carry out proper calibration. It won’t be taking you more than 30 seconds to calibrate it.

It consists of a metallic drum, this is known as the resistance unit. This unit will remain clamped against the rear-end tire of your bike. Little assembly was needed as we took this trainer out of the box. We were able to assemble the trainer without any hassle. A guide for assembling the trainer has also been provided. Moreover, you’ll find tutorials as to how you can set up this trainer on the manufacturers’ website. The stand as well as the other components of this trainer is quite robust and has a rugged. So, you should be able to carry out intense training sessions as well. The only major adjustment that we did was, replacing the rear-end tire skewer with the one that came with the trainer. The M2 is compatible with a majority of the mountain & road compatible bike frames. It is capable of fitting a wheel of 700c. Although, we weren’t able to fit a wheel that had 650c. Therefore, make sure that your bike’s wheel is compatible with this trainer before buying the trainer itself. You’ll clearly notice a widely visible yellow-colored knob that you can turn for tightening the resistance unit positioned against the rear-end tire. This unit clicks into position perfectly once it’s sufficiently tight. Once we tightened the unit and it was against the rear-end tire of our bike, then we proceeded with our training. This trainer also provided us electromagnetic resistance. We were very happy with how it performed as we connected it with the virtual training application, Zwift. As we used this application, it helped us in choosing various routes. Moreover, we participated in races while communicating with other riders. Zwift provided us continuous feedback related to our performances. Furthermore, we got a summary related to the statistics once we finished the session. We had a thorough virtual-riding experience while using the Zwift application. You should keep in mind that this application requires a subscription. Some of the sensors that this trainer consists of, were used to detect our workout stats such as speed & cadence. We did not use any additional sensors with this trainer. We connected the M2 using wireless connectivity features such as Bluetooth & ANT+ FE-C to our smartphones & tablets. Overall, this trainer has served us with very good durability. Also, mounting & dismounting a bike from the trainer did not take more than a minute. Lastly, our workout sessions were quite effective, to say the least.

We’ve had riding sessions of more than 300 miles while using this trainer. Initially, we used a mountain bike on this trainer, later on, we switched bikes to road bikes. The performance this trainer offered us is equally great for both categories of bikes. The Design & build quality of this trainer is spot on. Its performances are very quiet as well. To ensure that there isn’t any unwanted wobbling of this trainer, we have carpeted the surface on which we set up the trainer. We can watch Netflix while cycling, the noise isn’t too much to interrupt our binge-watch sessions. We’ve been using a smoother 27.5” trainer tire on our bike while setting it up on the trainer. You may find the instruction within the manual to be less clear. However, in case of any queries, contacting Saris will help solve your issues.

Frequently Asked Questions

Q1. What is a smart trainer?

Ans.: A conventional smart trainer generally consists of a stand that will be able to support your bike at the rear-end wheel. Whereas, there will also be a resistance unit. A smart trainer’s resistance unit has integrated electronics that are capable of transmitting your speed into an ANT+ device. You will also find a few smart trainers that consist of power meters. Most importantly, smart trainers will ensure that you have a more realistic indoor cycling experience. These applications feature options of simulating varying gradients so that your cycling experiences feel totally like real-life outdoor experiences. As you simulate climbing, the difficulty may increase. Lastly, you should be able to use the Zwift application with conventional trainers that consist of ANT+ sensors. However, a majority of trainers prefer going for a smart trainer instead.

Q2. What is Zwift?

Ans.: This is a turbo trainer application that will help you to connect your smart trainer to either your smartphone, tablet, or personal computer. It enables you to ride with your fellow cyclists within a virtual environment. This will undoubtedly be a cure for your boredom as you train indoors.

The following video would provide you an idea of how you’ll be able to use the Zwift application.

Q3. What pieces of equipment are required for the Zwift application?

Ans.: First and foremost, you’ll be needing a smart trainer. Provided that you require an immersive gameplay experience, then it is suggested that you use Zwift regularly. You can either use a direct drive based smart trainer, for example; Wahoo Kickr Core or the Garmin TacX Neo 2T. As for a trainer based on fluid resistance, Saris CycleOps Fluid² should be a good choice. Many smart trainers feature a direct drive design with an integrated power meter or resistance that can be varied. These trainers can also measure your power output. The variable resistance will make you feel as though you’re actually riding outdoors. As you ride uphill on this application, the resistance level will increase on the trainer. Whereas, it’ll decrease as you go downhill. Using a previous model of smart trainer that has Bluetooth or ANT+ sensors should be enough for using it with the speed/power sensors. The data that these speed/power sensors produce will in turn be transferred to either your smart device or personal computer. Moreover, it’ll be transferred to the application as well. Lastly, you’ll be needing an ANT+ dongle, This is a small USB stick. This will allow you to connect to your computer or smart device to communicate with your ANT+ sensors or power meter.

Q4. Do you need a smart trainer for Zwift?

Ans.: Nearly all types of trainers can be supported by Zwift. You can even use the classic trainer as well. One of the positive sides is any trainer is capable of working with a Zwift application as long as you are capable of mounting your bike that consists of speed sensors. Although, standalone bikes might not be compatible. However, you should select a Zwift supported trainer. This is because these are capable of estimating your power numbers with accuracy.

Q5. Do smart trainers damage your bike?

Ans.: If you use resistance trainers then you mustn’t tighten the connections on the rear-end hub. Make sure to test the time connection by spinning the wheel once you’ve tightened your trainer into the hub. Your bike’s wheel is supposed to spin freely. However, if you see that the wheel isn’t spinning freely, then you should know that it has been over-tightened by the trainer into the hub and this has resulted in compression into the bearings of the hub. Therefore, this may cause a significant amount of damage to your bike. Another possible damage maybe there is wear and tear on your bike’s rear-end tires while you use a resistance trainer. Lastly, if you tend to sweat a lot, then chances are, it may end up dripping right into your bike’s components and end up causing corrosion.
