Best exercise bike: NordicTrack's S22i Studio Cycle

Pros: Globe-spanning video content; large variety of ride types, including mountain bikes, road bikes, and casual rides; automatic resistance and incline/decline control

Cons: Expensive

The S22i Studio Cycle from NordicTrack is our favorite at-home stationary

bike thanks to its extensive library of globe-spanning rides and automatic resistance and incline/decline control. This means that while you're riding, all you need to do is pedal away and the bike makes all the necessary changes for you.

NordicTrack's content library is powered by iFit which offers more than just the standard in-studio rides (though it does have that, too). There's also the ability to choose a wide variety of locale-based routines. This means you can bike Mt. Fuji one day while following a mountain bike course in Chile the next. 

The bike's large onboard screen provides crisp video playback while showing you where you stand against other riders who've done the same course. Plus, the interface keeps track of how many miles you've done each week, the number of hours you've been on the bike, and how much elevation you've gained. There's even a built-in fan to keep you cool while riding.
