Smart turbo trainers
Which wheel-on trainer, if the software does not drive it?
Neither of these changes resistance to match a virtual climb. Both put a roller against a tire and let you set the effort by hand — which is a legitimate way to train indoors and much cheaper than the alternative.

A tick marks the better answer on that line only. Counting ticks does not decide the page — the two verdicts below do, because these products answer different questions.
The one that arrives ready to record. A Speed Sensor 2 in the box means the trainer produces data on day one without a second purchase, and a published footprint tells you whether it fits the corner you have in mind. It needs no mains power, which decides it for a garage with no socket.
No amazon.com listing was found for this one. We hold references for other markets but none for the United States, so it may not be buyable here — which is the first thing to weigh against anything below.
The one with published numbers where it counts for a heavier rider: six stated resistance levels and a 150 kg (330.7 lb) rated load, which is the only load figure in this hub. It is listed on three markets rather than six, so availability is worth checking before you plan around it.
Only with a separate speed or power sensor, and neither will change resistance to match the terrain. The Garmin ships with a speed sensor, which is the shortest path. For app-controlled resistance you need a smart trainer — the VEVOR and the Wahoo in this hub both are.
Red Loon states 26 to 29 inch wheels. Garmin does not publish a range on this listing, so confirm with the seller. Both are wheel-on, so the rear wheel stays in the bike — and many wheel-on trainers require a quick-release skewer rather than a bolted or thru-axle wheel.
Not immediately, and it is worth it if you ride indoors regularly. A roller wears a road tire quickly and unevenly, and the rubber dust ends up on the floor.
