Choose a smart trainer compatible with your bike’s frame and drivetrain, then compare power accuracy, simulated gradient and app connectivity. To get started, you need the correct fittings, a compatible device and, for direct-drive models, a suitable freehub body and cassette: always check which components are included.
How to choose
The first choice concerns how the bike is mounted. A wheel-on trainer works against the rear tyre; a direct-drive model requires you to remove the rear wheel and connect the bike to the trainer.
- Compatibility before performance: check the frame, rear axle and cassette, where applicable. Wheel size alone is not enough.
- Power accuracy: if you train using watts, compare the stated margin of error. A lower percentage indicates a tighter stated tolerance.
- Simulated gradient: this matters if you want to replicate uphill routes. You do not need to choose the highest value to get useful training sessions.
- Maximum power: assess this against your efforts, especially during sprints. It does not indicate how hard you will need to pedal during every session.
- Connectivity: check the protocols supported by the trainer, the app and the phone, tablet or computer you will use.
- Included equipment: also take into account any cassette, freehub body and adapters you may need to buy separately.
Suito, Suito-T and Rivo: what to check when comparing them
To compare these three models, you need the specifications for the exact version and the package contents. Suito, Suito-T and Rivo are not included in the data available for this guide, so we cannot confirm their features or say which includes a cassette, freehub body and adapters.
Before choosing between the three, ask for a comparison covering the same points for each:
- Maximum power, simulated gradient and stated accuracy.
- Connection protocols and compatibility with the app you want to use.
- Supported axle standards and included adapters.
- Type of freehub body fitted and compatible alternative freehub bodies.
- Whether a cassette is included, its number of speeds and tooth counts.
- Power supply and any other included accessories.
You can ask us to check the version and included equipment, also providing your bike model. The trainer’s name alone is not enough to know whether you can mount your bike straight away.
How to check your bike and axles
Start with the rear axle: identify whether the bike uses a quick release or a thru-axle. For the latter, you need the diameter and hub width, for example 12×142 or 12×148 mm.
- Find the standard in the bike manual or the frame and hub specifications.
- Compare it with the fittings supported by the trainer.
- Check whether the required adapters are included or optional.
- Check any frame restrictions on mounting the bike on a trainer and the available clearance around the rear triangle and brake.
An adapter for another standard should not be considered equivalent. If information is missing, have the mounting checked before tightening the bike in place.
Freehub body and cassette: two separate checks
The freehub body is the part on which the cassette is mounted. It must have the correct interface for that cassette: knowing only the number of sprockets is not enough.
- Identify the drivetrain: the bike’s brand, model and number of speeds.
- Identify the cassette: model, tooth counts and required mounting interface.
- Check the trainer’s freehub body: make sure it is suitable or that a compatible replacement is available.
- Check the installation: any spacers must be fitted according to the instructions for the freehub body and cassette combination.
Matching the tooth counts of the cassette on your wheel can make switching between road and indoor riding easier. A different cassette must also be checked for compatibility with the rear derailleur and chain length; the rear derailleur may need adjusting after installation.

What you need to get started
First prepare the essentials needed to operate the trainer, then the accessories that make your session more comfortable.
- Compatible bike and fittings: with the adapters specified for your axle.
- Suitable cassette and freehub body: for trainers that require them, if they are not already included in the configuration purchased.
- Power: a socket and the specified power supply, where required by the model.
- Compatible device and app: a phone, tablet or computer with a supported connection. Also check the app’s access requirements.
- Receiver if needed: if the device does not have the connection required by the trainer.
- Cassette tools: if you need to fit it or transfer it from the wheel; alternatively, you can have the workshop do the job.
A fan, water bottle, towel and mat to protect the floor are also useful. A device stand makes the screen easier to read; assess whether a front wheel support is needed by following the trainer’s instructions.
With a wheel-on model, check tyre pressure and contact adjustment according to the manual. Keep the drivetrain clean: you will find advice in the guide on how to clean your bike and chain.

Frequently asked questions
What is the difference between Suito and Suito-T, and how do they compare with Rivo?
A reliable comparison requires the specifications for the exact versions, which are not included in this guide's data. Before buying, check the claimed performance and, in particular, which cassette, freehub body and adapters are included.
Can I mount any bike on a smart trainer?
Compatibility is not universal. You need to check the axle standard, adapters, frame guidelines and, on direct-drive models, the freehub body and cassette.
Is a cassette included with the smart trainer?
It depends on the model and configuration purchased: you need to check the box contents. If one is included, still check that it is compatible with your bike's drivetrain.
Do I need a computer to use smart trainers?
You can also use a phone or tablet if it supports the app and connection required by the trainer. Check Bluetooth or ANT+ compatibility and whether a receiver is required.
