The TrainerRoad Web application guides you through workouts by connecting your computer to your power meter, heart-rate monitor, and other sensors. The $10-per-month service can even control the resistance of the Wahoo KICKR. If you prefer virtual racing and roads, the KineMap iPad app and service adds real-world street and race videos, tied to your pace.
Things to avoid
There's only one reason to go with a non-GPS cycling computer these days--and that reason is budget.
Stick with ANT+ computers and sensors for now, unless you connect to your smartphone. Bluetooth LE isn't well supported in cycling computers. That will change in the next year or two, but if you need something that works now, ANT+ is the answer.
We hate to say it, but unless you are a Polar die-hard, skip the proprietary wireless standard (and more-expensive sensors) and wait for the company's Bluetooth LE products.
Finally, don't buy a bike trainer without a flywheel. Without one to keep inertia, your wheel will screech to a halt if you stop pedaling.
