Overview & Ratings

Bike riding is a popular fitness activity for people of all ages because it is a low-impact activity that provides an effective cardio workout without causing too much stress on your joints. However, bike riding is a very weather-dependent activity. Snow, rain, wind, and extreme heat can all impact your ability to go for a bike ride. Sometimes a busy lifestyle means that you have to squeeze in a workout when it might not be safe to bike outside. When you can’t get outside for a bike ride, a stationary recumbent bike is the solution.

Among the recumbent bikes on the market, the Precor RBK 615 recumbent bike is one of the best. Once it is in your home, you will be able to use it without difficulty or any special training. As your fitness level increases, you can continue to challenge yourself by customizing your workouts. Based on our extensive analysis, we gave the Precor RBK 615 recumbent bike a rating of 8.5/10. While more in-depth information will be provided below, here are a couple videos to give you an overview of the features it offers:

The Precor RBK 615 recumbent bike comes with a range of features that make it easy to use. If you test one out, you will begin to appreciate all of the care that went into the design of this bike.

  • Step-Through Frame with Easy Seat Adjustment

    The combination of a step-through frame and quick seat adjustment of the Precor RBK 615 recumbent bike means that your time will go toward working out rather than getting ready to workout. Simply step one leg through to the other side of the bike, lift the yellow lever to slide the seat into position, and you are ready to go.

  • Ergonomic Design

    Engineers carefully designed the Precor RBK 615 recumbent bike to maximize efficiency and minimize strain on your joints. This ensures that your workout will be low-impact. Furthermore, the pads attached to the seats provide cushioning and support without interfering with your workout.

  • Dual-Sided Pedals

    The pedals included with the Precor RBK 615 recumbent bike have straps on one side and no straps on the other, so that you can choose which is most comfortable for you.

  • Standard Console with LED Display

    The layout of the console is straightforward and logical, making it simple to access the six preprogrammed workouts or to customize your workout. The resistance of the Precor RBK 615 recumbent bike can be changed at the touch of a button, even mid-workout. The LED display provides you with whatever workout data you need, whether it be time, distance, calories, speed, incline, resistance level, heart rate, or RPM.

  • Ventilated Air Flex Seat

    Recumbent bike users often complain about their clothing sticking to their backs. The Precor RBK 615 recumbent bike has a patented design that allows for airflow through the seat back, so that you can focus on your workout, rather than your sticky, sweaty clothes.

  • Built-In Heart Rate Monitor

    Touch heart rate monitors are built into the handlebars found on either side of the seat in the Precor RBK 615 recumbent bike. With this convenient feature, you can be sure you are keeping your heart rate in your target zone.

  • No External Power Source Required

    The Precor RBK 615 recumbent bike can be operated without a backup battery or external power source.

  • Warranty

    The Precor RBK 615 recumbent bike frame is protected by a lifetime warranty, while its parts and wear items are covered by a ten-year warranty. Unlike many other fitness products, labor is also covered by a limited warranty; in this case, it is a one-year warranty.

  • Shipping and Assembly

    When you purchase a Precor RBK 615 recumbent bike directly from Precor, it will be delivered to and assembled in your home by a professional. Most Precor authorized dealers also offer this service. If you order from, you will have the Amazon shipping options available in your location and will need to assemble it yourself.

Our Likes

The Precor RBK 615 recumbent bike is a solid choice for a home fitness program. Some people have the misconception that recumbent bikes are not a good investment because they are limited in how they can be used. Not so with this bike, since it can be used by different people with varying degrees of fitness. The careful engineering of the machine ensures a low-impact workout, making it perfect for people just starting a fitness program or people who have chronic joint injuries in their lower bodies. The ability to customize workouts means that this bike will provide robust workouts to even the fittest people.

Our Dislikes

Despite there being numerous reasons why we like this product there are also 2 drawbacks:

  • One downside of the Precor RBK 615 is that it has limited entertainment options. Only a reading rack is standard with Precor RBK 615 recumbent bikes. A Personal Viewing System (PVS) is available at an additional cost, though some users opt to watch movies or TV shows by using the reading rack to hold tablets or other mobile devices. If you have the available space and the correct equipment, you can even set up your bike right in front of a full-sized TV.

  • Another drawback of the Precor bike RBK 615 is its price. While it is substantially more expensive than most other recumbent bikes on the market, when you buy a Precor, you can trust that you’ll be using it for years to come. You won’t be in the market for a replacement just a few years down the road. Between its warranty and the quality of materials used in manufacturing the machines, you know that a Precor bike is built to last.

Our Verdict

Overall, the Precor RBK 615 recumbent bike is a lasting investment that is a perfect fit for your active, healthy lifestyle. You’ll be able to obtain robust workouts in any kind of weather and at any time of day or night, building cardiovascular fitness and muscle strength. This bike’s ergonomic design and patented ventilated seat will make even long workouts more comfortable than you thought possible. With its 6 preprogrammed workouts and 25 levels of resistance, the Precor RBK 615 recumbent bike will fulfill your fitness needs for years to come. Furthermore, given the high-quality materials and carefully engineered design Precor is famous for, you can be sure that your Precor RBK 615 will still be working as hard as you are well into the future. Since the price is significantly higher than other recumbent bikes on the market, we brought the overall rating down slightly to a score of 8/10. However, we believe that the purchase of a Precor RBK 615 is a solid investment that will pay off with increased health and fitness for many years to come.

“I work out in my college’s wellness center, which has these bikes. I was happy about how easy it was to figure out how to use all of its features. I recommend it for its quality.”
- Alishia M.

Most Comfortable

“I have ridden many recumbent bikes, including Lifecycle and previous Precor bikes. This was clearly the most comfortable and smooth for long rides of 60 minutes or more. It would be an even better product if it included calories per minute.”
- Michael D.

Great Product

“I think that this is great product! I can put it anywhere since it doesn’t need to be plugged into an electrical outlet. After trying it out at the community center where I work out, I knew it was the right product for me.”
- Mark Z.
