WHO THIS IS FOR
IS THIS YOU?
The cyclist buying their first smart trainer
You want to start training indoors with Zwift or another platform and need guidance on what to buy without overspending or underbuying.
The rider upgrading from a basic or wheel-on trainer
You have outgrown a basic trainer and want better accuracy, quieter operation, and a more realistic ride feel for serious structured training.
THE ROADMAN VIEW
The Roadman view
Anthony has tested numerous trainers over the years and discussed indoor training setups extensively on the podcast. His recommendation is straightforward: buy the best direct-drive trainer you can afford, and do not agonise over the differences between the top-end models. The gap between a $700 direct-drive trainer and a $1,200 one is measurable in lab conditions — fractionally better road feel, slightly lower noise, marginally more accurate power — but the gap between either of those and a $300 wheel-on trainer is enormous in daily use. Direct-drive trainers are more accurate, quieter, require less calibration, cause zero tyre wear, and feel more natural. That is a genuine upgrade, not a marginal one.
The features that matter most are power accuracy, noise level, and connectivity. Power accuracy within 1-2% means your indoor numbers match your outdoor power meter, which is critical for structured training — if your trainer reads 10% high, every workout target is wrong. Noise level matters because most of us train in a house with other people, and a loud trainer at 6am is a domestic hazard. Connectivity via both ANT+ and Bluetooth ensures you can use any app and any head unit without compatibility problems. Beyond those three, features like gradient simulation (up to 20% vs 12%) and maximum power resistance (2,000 W vs 1,500 W) are irrelevant for most amateur riders.
The smart bike category — where the entire bike is built into the trainer — deserves mention because prices have dropped. A smart bike eliminates compatibility issues, requires no setup, and offers the most realistic ride feel. But at $2,000-4,000, they are 3-5 times the price of a direct-drive trainer. For riders who train indoors 4-5 times per week year-round and have the budget, a smart bike is worth considering. For everyone else, a direct-drive trainer plus your existing bike is the right answer. Anthony's advice is simple: spend money on a good fan first, a good trainer second, and a good subscription third. The fan makes more difference to your indoor experience than any trainer upgrade.
EXPERT EVIDENCE
WHAT THE EXPERTS SAY
- Roadman CyclingRoadman Cycling indoor training coverage
We have compared direct-drive trainers from every major brand side by side, and the honest conclusion is that any reputable direct-drive unit from Wahoo, Tacx, Elite, or Saris delivers accurate, quiet, and reliable performance. The differences between them are smaller than the marketing suggests. Buy whichever is on sale and spend the savings on a powerful floor fan.

The biggest indoor training mistake is not about the trainer — it is about heat management. A rider on a $1,200 trainer in a hot, unventilated room will produce less power and have a worse experience than a rider on a $600 trainer with a good fan and an open window. The training environment matters more than the hardware.

PRACTICAL APPLICATION
DO THIS WEEK
Choose a direct-drive trainer in the $600-900 range
This price bracket offers power accuracy within 1-2%, quiet operation, realistic ride feel, and dual-protocol connectivity. Models from Wahoo, Tacx (Garmin), Elite, and Saris all compete in this range. Read recent reviews for the latest models, as the market updates annually. Avoid spending more unless you specifically need features like higher gradient simulation or integrated power measurement.
Invest in cooling before upgrading your trainer
A large floor fan (ideally two — one for the front, one at 45 degrees) makes a bigger difference to indoor training quality than any trainer upgrade. Without adequate cooling, core temperature rises 5-10 degrees above outdoor riding, reducing power output by 5-15%. A $50-100 industrial fan is the best indoor training purchase you can make.
Calibrate or spindown before every session
Even the best direct-drive trainers drift slightly with temperature changes. Perform a spindown calibration before each session (most apps have a built-in function) to ensure power accuracy. Let the trainer warm up for 5-10 minutes at moderate effort before calibrating — a cold trainer reads differently from a warm one.
COMMON MISTAKES
WHAT CYCLISTS GET WRONG
MISTAKEBuying the cheapest wheel-on trainer and expecting accurate structured training.
FIXWheel-on trainers with 5%+ power accuracy make structured training unreliable because targets are consistently off. If budget is a constraint, buy a used direct-drive trainer rather than a new wheel-on — the accuracy upgrade is worth the trade-off in cosmetics.
MISTAKENot accounting for noise in the purchasing decision.
FIXCheck decibel ratings and user reviews for noise levels at threshold power. A trainer that sounds acceptable at 150 W may be intrusive at 300 W. Direct-drive trainers are typically 30-50% quieter than wheel-on units. If you live in a flat or train early/late, noise is a critical factor.
MISTAKENeglecting the training environment while investing in expensive hardware.
FIXA $1,200 trainer in a hot room with no fan underperforms a $600 trainer in a cool, well-ventilated space. Budget for a fan ($50-100), a mat to protect flooring ($30-50), and a towel setup before considering premium trainer features. The environment determines the experience more than the hardware.
