This article compares the pros and cons of smart bike trainers and smart bikes (bike simulators). I summarized my experience and also talked with smart bike users to provide you with valuable insights.
KEY TAKEAWAY
Smart bike trainers are more affordable and portable. They don’t take up as much space when not in use, and there are more options on the market.
Smart bikes are quieter and cleaner thanks to the lack of a classic drivetrain. They allow you to adjust the fit easily and customize gears. They are also more stable when sprinting and require less maintenance than your bike.
Let’s scrutinize individual pros and cons in more detail.
Pros & Cons of Smart Bike Trainers vs. Smart Bikes
The following table summarizes the pros and cons of smart bike trainers and smart bikes.
| Training Device | Pros | Cons |
|---|---|---|
| Smart Bike Trainers | • More affordable (assuming you already have a bike) • Don't take as much space when not used • More choice on the market • More portable • More comfortable (depending on the model) | • Noisier • Not 'multi-user friendly' (you have to switch bikes) • Messier (because of your bike's drivetrain) • Not customizable gears (unless you buy new components) • Less stable during sprints • Wear out your bike's parts |
| Smart Bikes | • Quieter • Easily adjustable fit • Cleaner • Customizable gears • More stable during sprints • Don't wear out your bike's parts | • Pricy • Take up more space when not used • Less choice on the market • Less portable • Less comfortable (they are rigid) |
Let me now explain the individual differences below.
NOTE: Features like gradient simulation, resistance, accuracy, connectivity, etc., are usually the same or similar. For this reason, I won’t examine them further.

Price
One of the biggest factors you probably consider is the price.
While smart bike trainers cost hundreds to lower thousands of dollars*, smart bikes cost thousands of dollars.
*Assuming you already have a bike to mount in the bike trainer.
For example, Wahoo’s highest-end smart trainer (KICKR v5) has a recommended retail price of 1199.99Â USD. Their smart bike (KICKR Bike) is three times more expensive (3499.99Â USD).
Is this price difference worth it? Well, it depends on your preferences. Let’s examine the other features.
Space Requirements and Portability
Both training devices take up similar space when used. However, the situation changes when you need to store them when you don’t need them.
Bike trainers have foldable legs, allowing them to be stored in a closet, under a bed, in a garage, basement, etc. They often also have carry handles for easier portability.
Smart bikes require more storage space and are heavier. Therefore, it’s better to have a dedicated, permanent training area where you can keep them all year round.
Fit Adjustability
One of the biggest benefits of smart bikes over smart trainers is the possibility of adjusting their fit.
This also gives a space for multi-user usability. If more household members are interested in using the smart bike, you can quickly adjust the fit.
Different bike frame sizes and geometries make this impossible. It’s also not practical to change bikes before every training session.
Market Offer
There are dozens of smart bike trainers available, but the number of smart bikes is limited.
Smart bikes are more niche products, so manufacturers aren’t as motivated to develop more models.
Please don’t take me wrong. I am not saying you won’t choose from the smart bikes on the market. But, their offer is much narrower.
Noisiness
Smart bike trainers are pretty quiet. Often, your bike’s drivetrain creates more noise than the trainer itself. However, smart bikes are quieter thanks to the lack of the drivetrain (chain-chainrings-cassette).
This feature makes them more suitable for apartments and those who need a quiet training device that does not disturb other household members.
However, not even smart bikes are completely silent, especially when used with an indoor cycling fan or at higher intensities.
DC Rainmaker did great videos comparing the noise of the Tacx NEO trainers and smart bikes.
Stability
The general rule is that smart bikes are more stable than bike trainers. But this is also dependent on the bike trainer.
So, if your training plan includes sprint efforts, you should consider a stable trainer or maybe even a smart bike.
For example, Stages SB20 is a heavy smart bike weighing over 60 kg, providing a stable training platform.
Maintenance
While both training devices don’t require much maintenance, smart trainers have a significant disadvantage—you must maintain your bike.
When using your bike on a bike trainer, you wear out its parts like the chain, cassette, or chainrings.
You should also double-check the headset, handlebar, and other bolts for damage caused by your sweat from time to time.
Many people worry bike trainers can damage their bikes. But if you follow manufacturer instructions, you have nothing to worry about.
Smart bikes are almost maintenance-free. You only have to wipe off the sweat and dust. Manufacturers recommend an in-depth once or twice a year.
They are also much cleaner, so you don’t get chain oil or dirt on your floor.
Riding Comfort
Comfort-wise, it’s highly dependent on the bike trainer.
Some bike trainers, like the Wahoo KICKR v5 or ThinkRider X7 PRO, have a side-to-side tilt. This tilt reduces the friction between your bottom and the saddle, contributing to better riding comfort. Newer trainers, like the Wahoo KICKR Move and Tacx NEO 3M, have fore-and-aft movement.
Smart bikes are often rigid, so I recommend using them with a rocker plate. This also applies to rigid bike trainers. You can read rocker plate benefits for more info on why to use them.
Ease of Use
When you already have a bike in the bike trainer, you just hop on it and start riding. But mounting the bike in the trainer takes some time. Furthermore, you ‘lock’ your bike indoors. So, if you want to use the same bike outdoors, you must take it off.
That’s what you don’t have to worry about when having a smart bike. You will have one bike for riding indoors and one (or two, three) for outdoors.
This is something that women will appreciate. It may be complicated for them to put the bike on and off the trainer, so smart bikes are more convenient for them.
Conclusion
Based on the pros & cons explained above, I recommend:
Smart bike trainers for people on a budget who don’t mind mounting their bike into a bike trainer. They are more portable and take up less space but still provide similar features.
However, your bike components will wear out quicker than just riding outside. Also, due to the drivetrain, bike trainers tend to be noisier.
Smart bikes are suitable for passionate athletes, people living in apartments, or those with a dedicated training area where they can leave the bike all year round.
