Schwinn IC4 Review

The Schwinn IC4 is the top-of-the-line model in their indoor cycling bike range. Compatible with interactive at-home studio and virtual cycling workouts, this model is popular for a reason. The IC4 provides an excellent workout, high comfort, and functionality with popular apps like Zwift, Peloton, and JRNY (it comes with a 1-year JRNY membership). It's also highly valuable, as it retails for significantly less than many other connected bikes on the market.

Ride Experience & Programming

The Schwinn IC4 impressed us with its excellent exercise quality. This spin bike feels stable and sturdy at high input, and the resistance is smooth and quiet. It can be used as a stand-alone spin bike with manual workouts or connected to popular apps like Peloton and Zwift, as well as the included JRNY app for a studio or interactive virtual training experience. This versatility gives the IC4/C6 a competitive edge in this metric.

The IC4 is built around a beefy steel frame with adjustable leveling feet. With abundant resistance levels, it was easy to micro-adjust. During testing, we rarely turned the resistance above 70, which we found plenty challenging for quad-busting intervals. The resistance is controlled by an adjustment knob located below the handlebars, allowing for manual adjustments, whether in a workout or following an on-demand studio class.

While the IC4 is a smart bike with connected features, you can use it as a stand-alone bike for manual workouts without the need to connect to a device. In the bike's manual mode, you can start pedaling and adjust the resistance to your needs. You also have the option of setting a time, distance, or calorie workout goal through the bike's console.

Companion App/Connectivity

If manual workouts aren't exciting enough, you can connect your device via Bluetooth and use apps like Peloton, Zwift, and JRNY. These apps all have a monthly fee, but may be worth the cost to access thousands of live and on-demand studio classes on Peloton or the interactive virtual training world of Zwift.

If you do choose to use apps with the IC4, it is important to note that they have an additional monthly fee (Peloton is $12.99/mo, Zwift is $14.99/mo, and JRNY is free for a year, then $19.99/mo or $149/year) and require a device with a screen to serve as the display. Peloton has thousands of live streaming and on-demand studio workouts with various instructors and music to choose from, as well as scenic rides to watch while you spin away the time. Interestingly, the Peloton app is significantly cheaper with a compatible bike than with a Peloton brand bike. However, it doesn't provide all the features or performance data tracking. Zwift is a virtual interactive training app featuring thousands of structured training programs, races, and events, as well as a wide variety of maps and routes to follow. When connected, your device displays the virtual course you're riding, along with metrics such as speed, time, cadence, watts, and a leaderboard. JRNY offers trainer-led workouts, coaching, virtual courses to follow along with, and numerous off-bike workouts.

Fit & Adjustability

We found the IC4 to be an impressively comfortable exercise bike throughout testing. It features extensive handlebar and seat adjustability to fine-tune the fit for a wide range of rider heights and preferences, along with a comfortable performance seat and multi-position handlebars.

The IC4 has a maximum rider weight limit of 330 lbs. The handlebars and the seat are adjustable vertically and horizontally to accommodate a wide range of user heights. The seat post has 8.5 inches of vertical adjustment and 3 inches of horizontal adjustability. Likewise, the handlebar has 4 inches of vertical height adjustment and around 3 inches of horizontal adjustment. All this adjustability means you should be able to dial it in to suit your needs and comfort. Our six-foot-tall tester with a 32-inch inseam could fit perfectly on this bike, although he had the seat height in its highest position. Since Schwinn doesn't provide a height range, we measured the distance from the top of the seat to the pedal in its lowest position to find an approximate inseam range. With the seat pushed forward, we measured a range of 29.25 - 37.25 inches in its lowest and highest settings.

The IC4 can handle serious spin input and comes with a race style seat. The seat is narrow, performance-oriented, and perfect for the intense cycling workouts this bike was designed for. We found it quite comfortable, with adequate padding and a pressure-relief cutout, but riders who spend less time on a saddle may prefer a more supportive or wider option. The large, rubber-coated multi-position handlebar provides many hand positions to suit your riding style or preference.

Display & Controls

The Schwinn IC4 comes with a small LCD display and syncs with your device via Bluetooth for use with the Peloton, Zwift, and JRNY apps. Thanks to the LCD display, you can use this bike independently without an app or device connection, which gives it an edge over some connected or smart bike competitors. When connected to an app, your tablet or phone (not included) serves as a screen that displays the studio workout or interactive ride. The Schwinn 130 Upright Bike is the only other option with a user interface that we like as much as the IC4.

The LCD display is centered on the handlebars and measures 3" L x 2" W. The IC4 must be plugged in for the display and Bluetooth connection to work. The dark screen displays bright numbers and letters, showing a wealth of information at a glance, including cadence, elapsed time, estimated calories burned, speed, distance, resistance level, and pulse. The display turns on when you press any button or when the pedals move, triggering the RPM sensor. The screen automatically displays and records your workout information as soon as the pedals start turning. Your workout automatically pauses if the pedals stop turning for 2 seconds. When your workout ends, the display powers off after 5 minutes of inactivity. Five buttons located below the screen control all display functions, including Bluetooth, start/enter/reset, and up and down arrow buttons. The Bluetooth button pairs the bike with compatible devices and the included heart rate sensor, while the others start a workout or let you enter a time, distance, or calorie goal for a manual workout.

Above the display is a padded device holder designed to hold a tablet or smartphone. The display has a USB charging port to keep your device charged while you ride. Using its Bluetooth connectivity, the IC4 is compatible with the Zwift, Peloton, and JRNY apps for a studio or interactive cycling experience.

Build Quality & Accessories

The most impressive feature at this price point is its connectivity and functionality with third-party training apps.

If you're highly motivated, you may not need the added inspiration that live streaming, on-demand, or virtual training can provide, but we think it's nice to have the option. Unlike the more expensive competition, the IC4 does not come with a high-tech console for streaming workouts. It features a device holder for easy viewing and a USB port to keep your device charged while you ride. It also comes with a Bluetooth heart rate armband to monitor your pulse during your workout.

The IC4 has two bottle holders with cradles to hang the included 3 lb hand weights. It includes dual-function pedals with cages on one side and SPD clips on the other, so you can choose the footwear that best suits you; SPD cleats are also included. The front stabilizer features integrated transport wheels, making it easy to move this heavy bike. Each foot has independent levelers to help stabilize the bike on uneven surfaces. It also comes with an impressive 10-year frame warranty and a three-year electronics warranty.

Size & Setup

Compared to other exercise bikes we've tested, the Schwinn IC4 was fairly involved and time-consuming to assemble. The build requires quite a few steps. All told, it took a little over an hour to get this bike from the box to ride-ready.

The IC4 weighs 106 lbs when assembled, and the box was much heavier, so having another person help remove the bike from the package was helpful. Once removed from the box, one person can complete the remaining tasks. Removing the protective packing materials from the bike and its parts takes several minutes, and most of the remaining assembly is relatively standard. The printed directions are detailed and easy to follow, and they include all the tools and hardware you need. After attaching the front and rear stabilizers, pedals, handlebars, seat, and seat post, install the device holder and bottle holders/dumbbell holders.

Once the IC4 is assembled, the bike has dimensions of 48.75" L x 21.25" W x 52" H. Moving it around on hard surfaces is relatively easy thanks to the transport wheels. Moving it up or down stairs may be difficult because of its weight.

Should You Buy the Schwinn IC4?

The Schwinn IC4/Bowflex C6 isn't exactly cheap, but it's a good value. It performs roughly on par with big-name home studio competition and comes with a 10-year frame, 3-year mechanical and electrical parts, and a 1-year labor warranty. This bests most of the competition. Except for a dedicated screen, the IC4/C6 is one of our favorite exercise bikes. We recommend it to anyone looking for versatility, comfort, and a solid workout.
