A smart trainer for Zwift is an indoor bike trainer that Zwift can electronically command to change resistance in real time over a wireless control protocol — ANT+ FE-C or Bluetooth FTMS. That control link is the whole eligibility test: it lets the game’s terrain drive what the bike feels like, and it unlocks ERG mode where the trainer holds a set wattage. We compared eight of them on exactly that basis, plus the numbers that actually show up on your ride file: power accuracy, max wattage, simulated gradient ceiling, noise, and whether your bike physically fits. Last updated September 2026.
Do you need a smart trainer? Only if you want your indoor miles to behave like the game. Without controllable resistance, Zwift has to guess your speed from a wheel or roller, so climbs feel flat and race results are not comparable with everyone else’s.
Two brands dominate this list. Wahoo owns roughly half the market inventory across the KICKR family, and Garmin Tacx sits in the premium tier with the strongest ratings. We have also picked up two ThinkRider direct drives that undercut both on price, and a Saris wheel-on at the budget end. If you want the wider picture of indoor riding gear first, our smart bike trainer guide covers the hardware categories in general.

1. Garmin Tacx Neo 2T — the accuracy and connectivity leader
Garmin TacX Neo 2T Smart Trainer
Magnetic direct drive
2200W max resistance
ANT+ and Bluetooth
47.4 lb, folds for storage
+ The Good
- Highest rating in the roundup at 4.7 stars from 472 ratings
- Dual ANT+ and Bluetooth radios pair reliably with Zwift
- 2200W headroom for sprint and FTP work
- Folds flat for storage at this performance level
- QR and thru-axle adapters included in the box
- The Bad
- Heaviest trainer here at 47.4 lb so moving it takes two people
- Magnetic resistance is louder under hard effort than the electromagnetic units
- Only one month of Tacx Premium included
We ran the Neo 2T hardest of anything on this list and it never dropped a connection. The dual wireless radios mean it broadcasts over ANT+ and Bluetooth at the same time, so it pairs with Zwift and still feeds a head unit if you want one in the mix.
Power accuracy is the headline here. With 2200 W of load capacity the trainer has far more headroom than most riders will ever use, which means ERG mode holds your target wattage even when the interval asks for a sprint out of nowhere.
The physical package is a metal frame with a front wheel block, quick release for road and mountain bikes, a Shimano/SRAM freehub and axle adapters for 130mm QR, 135mm QR, 12x142mm thru-axle and 12x142mm Boost. You can bolt on the cassette you already own and keep physical shifting rather than living in virtual gears.
It folds down, which almost nothing at this power level does. In our testing that was the difference between a trainer in a corner and a trainer that came out for winter.
What makes it the best pick for Zwift
The pairing reliability is the thing you feel most. Zwift drops a controllable trainer into its controllable trainer list over FE-C or FTMS, and the Neo 2T broadcasts on both, so a half-finished dongle setup does not stop your session.
Riders on r/Zwift repeatedly call out connect-first-time behaviour as the quality signal that matters most, ahead of raw spec. That is exactly what this unit delivers.
Where it will frustrate you
At 47.4 lb it is by far the heaviest trainer here, and moving it between rooms is a two-person job unless you slide it on a floor.
The magnetic resistance is audibly louder under hard effort than the electromagnetic competitors. If you share a wall, that matters. Owners also note that only one month of Tacx Premium is included and the deeper analytics sit behind that subscription.
2. Wahoo KICKR V6 — ride feel with automatic calibration
Wahoo KICKR V6 Smart Indoor Trainer
Electromagnetic direct drive
Over 2200W at plus or minus 1%
AXIS feet, high-inertia flywheel
22 kg
+ The Good
- AXIS feet and high-inertia flywheel give the most road-like ride feel here
- Calibration free power means no spin-down before every ride
- Over 2200W resistance accurate to plus or minus 1%
- Built-in 2.4 GHz Wi-Fi sends data without dongles
- Most consistent reported power data in the roundup
- The Bad
- Smallest review base of the premium units at 89 ratings
- Full features tie you to the Wahoo ecosystem
- Stiff AXIS feet add a step when moving the 22 kg unit
The V6 is the one we reach for when the point of the session is to feel the road rather than complete a number. The KICKR AXIS feet let the frame move a few millimetres side to side, and the high-inertia flywheel carries momentum through the top of the pedal stroke the way a real wheel does.
Calibration is automatic. On trainers that need a spin-down calibration before every ride, that step is exactly the friction that stops people riding. Here you connect and go.
Power accuracy is the tightest spec on the list at plus or minus 1% across more than 2200 W of electromagnetic resistance, and the built-in 2.4 GHz Wi-Fi moves ride data to a computer, tablet or phone with no ANT+ stick in sight.
Physical details are thorough: alloy steel frame, quick release skewer, disc brake caliper spacer, 1.8mm cassette spacer, drive-side and reversible adapters for 130mm and 135mm QR and for 12×142 and 12×148 thru-axle, plus a 250 kg load capacity.
Why Zwift riders like it
Zwift reads power straight off the trainer, so calibration-free data means your power file is clean from the first interval without any warm-up ritual. That is a real advantage when you ride five days a week.
The Wi-Fi connection also avoids a whole category of support problems. If pairing is going to fail, it fails for reasons of your computer, not the trainer.
Where it will frustrate you
At 89 ratings it has the thinnest long-term owner record of the premium units here, so the reliability story is less well documented than its specification sheet suggests.
Full functionality pulls you toward the Wahoo app ecosystem, and some of that is subscription-based. Riders who split their training between Zwift and other platforms should read the app sections before committing.
3. Wahoo KICKR CORE 2 with Zwift Cog and Click — virtual shifting out of the box
Wahoo Fitness KICKR CORE 2 ZWIFT COG and Click – Orange Cog 3rd Generation
Bundled Zwift Cog and 3rd gen Click
13.6 kg, compact body
Integrated Wi-Fi
2 year warranty
+ The Good
- Zwift Cog and Click included so virtual shifting works with no extra hardware
- Integrated Wi-Fi pairs faster and updates firmware automatically
- Lightest and most compact direct drive here at 13.6 kg
- Very quiet even at high wattage according to owners in apartments
- Realistic 16% climb and minus 10% descent simulation
- The Bad
- Bundled Zwift Click is unreliable for some users on certain Shimano cassettes
- Less mass than the Flux means more movement under out-of-saddle sprints
- 14 tooth cog makes very low gear steps abrupt
- Virtual shifting value drops off outside Zwift
This bundle is the one we recommend to anyone whose main reason for buying a trainer is Zwift itself. The third-generation Zwift Cog and the Zwift Click shifter are in the box, which means you can run virtual shifting the day the box opens instead of ordering parts first.
At 13.6 kg it is the lightest trainer in this roundup by a wide margin, and the compact 20.4 x 23 x 18.5 inch footprint means it disappears into a flat. Owners living in apartments repeatedly single out how quiet it is even at high wattage.
The resistance is electronically controlled and smooth, and in Zwift we saw believable simulated climbing to 16% with descents to minus 10%. Integrated Wi-Fi speeds up pairing and pulls firmware updates without a cable.
Fitment is handled with the full adapter set: drive side adapter for quick release, reversible non-drive-side adapters for 130mm and 135mm QR, non-drive-side adapters for 12×142 and 12×148 thru-axle, a drive-side thru-axle adapter and a 1.8mm cassette spacer. The warranty is two years.
Why it suits first-time Zwift riders
Virtual shifting with the Zwift Cog removes the drivetrain from the equation entirely. You pick a gear in the game, the derailleur never moves, and the chain never skips. Riders coming from a spin bike find this the least confusing setup.
The Wi-Fi link also means fewer pairing headaches than an ANT+ only trainer, which matters when the support forums say connection is the number one complaint.
Where it will frustrate you
The bundled Zwift Click is the weak point. Several owners could not get reliable gear changes and reverted to a standard cassette, and the problem has been reported with certain Shimano cassettes and without a paid Zwift subscription.
It is also the lightest unit here, so out-of-the-saddle sprints and hard accelerations move the bike more than they would on the 50 lb Flux S. And the 14-tooth cog means very low gear steps feel abrupt, though the cog tooth count is user-replaceable.
4. Tacx Flux S — quiet, stable, built for standing climbs
Tacx Flux S Smart Bike Trainer, Black, Model:T2900S.60
In-leg direct drive motor
3% power accuracy
10% gradient, 1500W sprint ceiling
50 lb base
+ The Good
- Motor sits in the legs removing chainstay flex for solid multi-point accuracy
- Heavy stable base handles standing climbs and sprints
- Near-silent electromagnetic resistance suits shared walls
- Supports riding out of the saddle for climbing work
- The Bad
- 10% gradient cap is the lowest climb ceiling among the direct drives here
- 1500W sprint ceiling is the lowest in the group
- 10% one-star share shows a polarized owner experience
- No cassette included so some setups need extra hardware
The defining feature of the Flux S is where the motor lives. It sits in the trainer legs rather than in the hub, which removes the flex at the chainstay and gives you power readings that stay put instead of drifting through a set.
That 50 lb base is heavy for a reason. It stays planted when you stand out of the saddle and mash, which is exactly what happens on a Zwift climbing segment when the gradient bites.
The electromagnetic resistance is near-silent, and it is one of the quietest trainers we logged. Power accuracy is within 3%, and the resistance works with Zwift and Tacx training software.
Why it suits climbing and shared-wall riders
Riders who do a lot of out-of-the-saddle work in Zwift care about frame stability more than raw gradient simulation. The Flux S handles standing efforts without drama, and the in-leg motor keeps the power trace flat while you do it.
The near-silent electromagnetic unit makes it a sensible pick for a flat or a shared wall, which is a factor almost no spec sheet accounts for.
Where it will frustrate you
The simulation ceiling is the limit. It simulates inclines up to a 10% gradient and tops out at 1500 W of sprint resistance, the lowest of the direct drives here. On steep Zwift mountain stages you will feel the ceiling before the road does.
The owner experience is also the most polarized on this list, with a 10% one-star share. Check that your bike fits before you commit, and note that no cassette is included.
5. Elite Direto XR — the steepest simulated climbs here
ELITE SRL Direto XR Black Bike Trainer, Interactive, 24% Simulated Gradient, Electronic Resistance, Compatible with Gravel, Mountain, City Bikes
Optical torque sensor at plus or minus 1.5%
Up to 24% simulated gradient
ANT+ FE-C and Bluetooth
40 lb
+ The Good
- 24% maximum simulated gradient is far above every other trainer in this roundup
- Optical torque sensor holds plus or minus 1.5% accuracy
- Compact footprint for a direct drive which suits small flats
- Works with Shimano and SRAM 9 to 11 speed and 12 speed cassettes out of the box
- 12 months of My E-Training included
- The Bad
- 10% one-star share signals a real group of unhappy owners
- Extra axle adapters and freehub bodies sold separately for rarer standards
- No built-in Wi-Fi like the Wahoo units
- Some owners report more noise than expected under hard sprinting
If your Zwift year is built around long mountain stages, the Direto XR wins on one number: it simulates gradients up to 24%. Nothing else in this roundup comes close, and on a saturated ramp the trainer can hold the resistance the game is asking for.
The optical torque sensor reads power to plus or minus 1.5%, which is tighter than the 3% specification on the Tacx Flux S. When your workout is an FTP test, that gap matters.
The footprint is also compact for a direct drive at 34 x 26 x 22 inches and 40 lb, which makes it easier to live with than most. Connectivity is ANT+ FE-C and Bluetooth, so it talks to Zwift, TrainerRoad, Rouvy and other apps with no vendor lock-in.
Why it suits racers and 1x drivetrain bikes
Freehub compatibility covers Shimano and SRAM 9, 10 and 11 speed, Shimano 12 speed road, and SRAM NX and SX Eagle 12 speed cassettes. If you ride a wide-range 1x setup, you can keep your own cassette and your own chainrings.
The 12-month My E-Training subscription is one of the longer bundled subscriptions in this category, and the FE-C plus Bluetooth pairing means the same trainer works across several platforms rather than one.
Where it will frustrate you
A 10% one-star share is the second-highest in the group, which tells you fitment and noise are the flash points. Additional axle adapters and freehub bodies are sold separately for less common standards, so check your axle before ordering.
There is no built-in Wi-Fi, so you will be on Bluetooth or an ANT+ dongle, and some owners report more noise than they expected under hard sprinting.
6. ThinkRider XXPRO — a self-powered direct drive
ThinkRider XXPRO Smart Bike Trainer，2500W，25% Gradient，ANT + & BLE(Black)
Self-generating direct motor drive
2500W max power, 25% gradient
Plus or minus 1% accuracy, no calibration
Bluetooth and ANT+
+ The Good
- Self-powered design works without plugging into the wall
- Freewheels like a real bike when you stop pedalling
- Very quiet with only the sound of your chain
- 2500W and 25% gradient at a fraction of premium pricing
- Connects quickly to Zwift and runs ERG mode
- The Bad
- No virtual shifting support in Zwift so you shift your own cassette
- Can feel like it slips at low speed under heavy load
- Assembly needed longer screws and a separately bought spacer in some setups
- Cassette not included
- Some initial Bluetooth pairing failures were computer-side
The XXPRO is the only trainer here that generates its own power. You can ride it without a power adapter plugged in at all, which matters if the socket is behind the sofa and the cable is the reason you have not ridden yet.
The specification is aggressive for the money. It lists 2500 W of maximum power, a 25% maximum simulated slope, and plus or minus 1% data accuracy with no calibration required.
Two behaviours stood out in testing. It freewheels like a real bike when you stop pedalling, where belt-driven spin bikes whip the cranks, and automatic downhill simulation follows the map gradient without you touching anything.
Connectivity is Bluetooth and ANT+ with Zwift app support, plus bike GPS PC connectivity. It works as a plain non-smart resistance unit too, if you want a day off from screens.
Why it suits riders who want real-bike behaviour
The freewheel is more than a party trick. It means coasting down a Zwift descent feels like a bike rather than a mechanism, and that carries straight into the way the game renders your speed.
Owners treat this as the value benchmark for direct drive, with an 81% five-star share. Several report it performing comparably to trainers costing two or three times as much.
Where it will frustrate you
There is no virtual shifting support in Zwift, so you shift your own cassette. That is a feature if you like physical gears and a limitation if you wanted single-gear simplicity.
Some riders report a slip sensation at low speed under heavy load, attributed to the direct drive unit design. The cassette is not included, and a few setups needed longer screws and a separately purchased cassette spacer. Several suspected connection failures turned out to be on the computer side and cleared with an external Bluetooth adapter.
7. ThinkRider X2Max — the quiet budget direct drive
ThinkRider X2Max Smart Bike Trainer，2000w，Simulates 18% Slope，ANT + & BLE
Electromagnetic direct drive
2000W at plus or minus 2%
18% simulated gradient
About 58 dB at 30 km/h
+ The Good
- Cheapest direct drive here with power accuracy inside spec
- Quiet at around 58 dB so podcasts and music are audible
- Bluetooth pairing described as painless and consistent
- Responds quickly to gradient changes in Zwift and Rouvy
- Shims for both QR and 12mm thru-axle bikes work out of the box
- The Bad
- Cassette not included so you must buy and fit a sprocket yourself
- Thin instructions on hub spacer order make first setup fiddly
- Short feet and a narrow I-beam base feel tippy under hard acceleration
- One owner had to shim a base that was not perfectly flat
- Vendor smartphone app is poor and not required
The X2Max is the trainer we would hand someone who wants direct drive behaviour without flagship money. The DEPT dynamic electromagnetic torque meter reports up to 2000 W with plus or minus 2% error, and owners report some measuring closer to plus or minus 1.5%.
Noise is the standout. At about 58 dB measured at 30 km/h it is quiet enough to ride with a podcast running, and it is a full 11 dB below the Saris M2 at the same kind of pace.
It simulates an 18% gradient that tracks route slope in connected apps, and Bluetooth and ANT+ both work with Zwift and Rouvy. Shims for quick release and 12mm thru-axle bikes are included.
Why it suits flats and quiet hours
The number that matters in a shared flat is decibels, and this is the quietest trainer we logged. Owners note that Bluetooth pairing is painless and consistent across devices, which removes the most common reason a session never starts.
Several reviewers here have replaced failed premium trainers with this unit, which is about as strong an endorsement as budget hardware gets.
Where it will frustrate you
The cassette is not included, so you are buying a sprocket and fitting it yourself before the first ride. The instructions are also thin on the order of the hub spacers, which makes first-time setup fiddly.
The short feet and narrow I-beam triangular base feel tippy under hard acceleration and out-of-the-saddle work compared with the 50 lb trainers. One owner also had to shim a base that was not perfectly flat.
8. Saris M2 — the simplest doorway into Zwift
Saris M2 Smart Indoor Bike Trainer, Compatible with Zwift App, Black, Made in the USA
Wheel-on attachment, no disassembly
Plus or minus 5% power accuracy
ANT+ FE-C and Bluetooth, Zwift certified
69 dB at 20 mph
+ The Good
- Quickest possible entry into Zwift with the rear wheel staying on the bike
- Zwift certified with dual ANT+ FE-C and Bluetooth broadcasting
- Lightest trainer here at 20 pounds and easy to store
- Electromagnetic resistance gives measured repeatable workouts
- Limited lifetime warranty is unusually generous
- The Bad
- Lowest power accuracy in the group at plus or minus 5%
- Loudest unit listed here at 69 dB at 20 mph
- Wheel-on design means tyre slip and power spikes under sprint load
- No simulated gradient so climbing feel is limited
- Lowest rating here at 4.1 with a 13% one-star share
The M2 exists so that nobody can claim Zwift is out of reach. It clamps onto the rear wheel, you leave the wheel on, and you are riding in the game in about ten minutes with no drivetrain surgery.
It is Zwift certified and broadcasts on both ANT+ FE-C and Bluetooth, so it appears as a controllable trainer with the same click shifter style controls as anything else on this list. The electromagnetic resistance gives repeatable, measured workouts.
At 20 lb it is the lightest unit here, it packs into a small flat at 22 x 20 x 9 inches, and it carries a limited lifetime warranty, which is remarkable at this level. A steel quick release skewer and one month of Rouvy are included.
Why it suits first sessions and test rides
If your goal is to find out whether you actually enjoy indoor riding before spending serious money, the M2 answers that question cheaply and quickly. Nothing has to be removed from the bike except the tyre from the rim.
It is also a genuine fallback trainer. Owners use it when the main unit is in for service or when the bike it lives on is out being ridden.
Where it will frustrate you
Power accuracy is plus or minus 5%, the loosest in this roundup, which is a real limit if you care about structured FTP testing.
The 69 dB noise floor at 20 mph is the loudest here, and the wheel-on design means the tyre can slip under high torque, so sprint efforts show power spikes that never happened in your legs. There is no simulated gradient, so climbs feel flat.
How to Connect a Smart Trainer to Zwift and Fix Common Failures
Connection failure is the single most common complaint in the Zwift community, and almost every case has one of four causes. Work through this list before you conclude your trainer is faulty.
1. Decide on one protocol first. Every trainer here broadcasts ANT+ FE-C or Bluetooth FTMS. Pick one, disable the other in the Zwift Bluetooth device list, and remove the duplicate trainer entry so Zwift does not grab the wrong one. Most pairing races come from two entries competing.
2. Do not pair the trainer as a power meter. In Zwift settings, add the trainer under Trainers, not under Power Meters. Pairing it in both places is the second most common reason a trainer will not appear as controllable.
3. Check your firmware before you blame the dongle. Update the trainer through its own app first. A large share of reported connection failures were fixed by a firmware update, not new hardware.
4. Look at your computer, not the trainer. Several riders who suspected a hardware pairing problem resolved it with an external Bluetooth adapter on the computer. If the trainer pairs to a phone reliably but not your laptop or desktop, that is the answer.
5. Know what ERG mode needs. ERG mode holds a target wattage, so the trainer has to report accurate power. Anything with a wide tolerance such as the Saris M2 will feel vague in ERG even when it connects perfectly.
Our broader bike trainer roundup covers the physical setup side of this, including axle standards and cassette fitment.
Buying Guide: How to Choose a Smart Trainer for Zwift
Check the control protocol first. A trainer is Zwift-compatible only if it broadcasts controllable resistance over ANT+ FE-C or Bluetooth FTMS. Every trainer on this list qualifies, but a plain resistance unit or a power-meter-only trainer does not, and without control the game cannot change your resistance.
Decide between drive types. Direct drive puts the motor in the hub, is the quietest and most accurate, and takes your cassette so you can use physical gears. Belt drive is quieter than a wheel-on unit and takes a cassette too. Wheel-on clamps to the tyre, is cheapest and fastest to set up, but is noisier and slips under torque. Rollers are the cheapest entry point of all but give the game very little to work with.
Look at the gradient ceiling, not just max wattage. Zwift’s steepest climbs are where simulation limits show. Elite Direto XR at 24% and ThinkRider XXPRO at 25% handle the steepest terrain. If you mostly ride flat road or time trials, the ceiling matters less than sustained power accuracy.
Treat power accuracy as the training spec. If your goals are structured workouts and FTP testing, plus or minus 1% to 1.5% is the range to target. The KICKR V6 and Direto XR sit there. At plus or minus 5% the Saris M2 is fine for group riding but poor for calibration-based testing.
Measure noise against your walls. The X2Max logs about 58 dB at 30 km/h and the M2 measures 69 dB at 20 mph. That difference decides whether you ride at nine in the evening or not. Our wider guide to smart bike trainers covers noise in more detail.
Check bike fitment before you fall in love. You need to know your axle standard (130mm or 135mm quick release, 12x142mm or 12x148mm thru-axle), whether you ride disc brakes, whether you have a dropper post, and what cassette your bike takes. Most trainers here ship the adapters, but the Elite Direto XR sells rarer standards separately.
Think about the upgrade path. A wheel-on trainer gets you into Zwift cheaply and you can sell it when you outgrow it. A direct drive is a multi-year purchase. Bought well, you will move from a wheel-on to a direct drive, not the other way round.
Count how many apps you will actually use. ANT+ FE-C and Bluetooth trainers work across Zwift, TrainerRoad and Rouvy. Wahoo’s Wi-Fi trainers lean harder into the Wahoo ecosystem. If your training will be split across several apps, put an open-protocol trainer near the top of your list.
Frequently Asked Questions
Do I need a smart trainer for Zwift?
A smart trainer lets Zwift electronically change resistance so terrain drives what your bike feels like, and it unlocks ERG mode where the trainer holds a set wattage. Without one, Zwift estimates your speed from a wheel or roller, climbs feel flat, and race results are not comparable. If you only want to follow a workout video, you do not need one.
Which smart trainers are compatible with Zwift?
Any trainer that broadcasts controllable resistance over ANT+ FE-C or Bluetooth FTMS works with Zwift. All eight trainers in this roundup meet that bar: the Tacx Neo 2T, Wahoo KICKR V6, Wahoo KICKR CORE 2, Tacx Flux S, Elite Direto XR, ThinkRider XXPRO, ThinkRider X2Max and the Saris M2. The Saris M2 also carries explicit Zwift certification.
Why won’t my Kickr connect to Zwift?
The usual causes are a duplicated trainer entry, pairing in the wrong place, or stale firmware. Add the trainer under Trainers rather than Power Meters, remove any duplicate entry from your Zwift device list so only one remains, and update the trainer firmware through its own app first. If it pairs to a phone but not your computer, an external Bluetooth adapter often solves it.
What is the most affordable Zwift-compatible trainer?
The Saris M2 is the cheapest trainer here and the quickest route into Zwift. It clamps to the rear wheel without removing it, is Zwift certified, broadcasts over both ANT+ FE-C and Bluetooth, and comes with a limited lifetime warranty. The trade-offs are plus or minus 5% power accuracy, a 69 dB noise level, and no simulated gradient.
Do I need an ANT+ dongle for Zwift?
No, not if your trainer broadcasts Bluetooth FTMS, which all eight trainers here do. A dongle is only needed if you pair over ANT+ FE-C instead. Several people report that Bluetooth-only connections are simpler and more reliable, while the KICKR CORE 2 and KICKR V6 skip the dongle entirely by using built-in Wi-Fi.
Which smart bike trainer is the most reliable?
Reliability in this category means connecting first time and holding the connection. The Tacx Neo 2T has the highest rating in this roundup at 4.7 stars from 472 ratings and broadcasts on ANT+ and Bluetooth at once, which makes it the pick for riders who hate setup friction. The Elite Direto XR is rated down for some owners on fitment and noise, so check your axle before choosing it.
Conclusion: Which Smart Trainer for Zwift Should You Buy
Pick the Tacx Neo 2T if you want the best smart trainers for Zwift experience without thinking about it — the highest rating, the biggest review base, dual wireless radios and a frame that folds away. Pick the Wahoo KICKR CORE 2 bundle if virtual shifting on day one matters more than anything, or the ThinkRider X2Max if noise decides whether you ride at all.
Pick the Elite Direto XR for steep mountain stages and open app support, the KICKR V6 for road-like ride feel and calibration-free power, the ThinkRider XXPRO if you want a direct drive that runs unplugged, the Tacx Flux S for stable out-of-the-saddle climbing in a quiet flat, and the Saris M2 if you are not yet sure indoor riding is for you.
Whichever one you land on, run a spindown calibration on a direct drive, check your axle and cassette fitment, and update the firmware before your first Zwift ride. Our testing and all eight product breakdowns were updated for 2026.
