Product Review

Enjoy low-impact, non-weight-bearing cardio workouts with the RBK 815 Recumbent Exercise Bike from Precor. Used in fitness centers worldwide, the RBK 815 allows you to step through easily, seating you in a reclining position to take weight off sensitive areas and distribute it over the patented air flex seat for a comfortable ride. Six workout programs and 25 resistance levels are complimented by touch and telemetry heart rate monitoring with Smart Rate. When you enter your age and weight, Smart Rate helps you stay in your fat burn, cardio, or peak target zone for a more efficient and cardio and weight-loss workout.
The custom-designed air flex seat features a ventilated panel and a unique suspension system.


The RBK 815 exercise bike feature a 14-inch step-through design with a low, 4-inch step-over height to make it easier to mount. Console handlebars help with entry and exit, while the riding handle bars provide optional hand and arm positioning and heart rate monitoring. The custom-designed, patent-pending air flex seat features a ventilated panel and a unique suspension system for a cool, cushioned ride. Using one hand, you can easily adjust the seat to any of 11 positions, whether you're on or off the bike.

Designed for Knee Over Pedal Spindle (KOPS) biomechanics, the seat is at an optimal position for more efficient pedaling and reduced shear force on the knee. This places the forward knee directly over the ball of the foot (or pedal spindle) when the pedals are in a horizontal position. Dual-sided pedals allow you to use them with or without the integrated straps. The pedals are extra-wide to comfortably accommodate feet of all sizes and ensure proper pedaling form.

Among the bike's other highlights is an LCD console that offers a clear, familiar layout and displays data such as calories burned, distance traveled, speed, time elapsed, time remaining, and percent complete. A convenient tap control provides an audible click when you press a key. Drink and accessory holders are conveniently located and ideal for portable music players. The bike is also equipped with handy transport wheels.

The RBK 815 sports a two-stage drive system that yields smooth, comfortable, quiet operation with a lower start-up resistance and more consistent resistance progression than typical single-stage drive systems. The three-piece crank tightens positively, reducing the need for periodic adjustments, and the 170-millimeter crank arm accepts any standard road or mountain bike pedal. An easy-to-remove shroud ensures quick access to the belt-drive system for maintenance and servicing without having to remove the pedals or crank.

The bike's steel frame has been treated with a two-step powder coating process for a rust-resistant undercoat and a cosmetic topcoat. Pedal axles and bearings are designed for smooth operation and exceptional durability. The bike measures 67 inches long by 49 inches high by 23 inches wide and weighs 210 pounds.

This review is from: Precor RBK 815 Commercial Series Recumbent Exercise Bike (Sports)
I had used an older model PreCor at a local gym, having compared it to Cybex as well as StarTac. Without any reservation I recommend this recumbent bike as being very very well made, not too difficult to assemble (most of it is already). Great resistance as well as many programs designed to keep interest. High recommendation.

This review is from: Precor RBK 815 Commercial Series Recumbent Exercise Bike (Sports)
I love just about anything Precor makes. I have invested in most of it because I would rather spend money on fitness than on medical bills whenever possible. For some reason I just never got around to getting the Recumbent Exercise Bike until this week, even though I've always wanted it. The Precor AMT is my all-time favorite, but I like to kick things up a little so I don't get in a rut.

I absolutely love this exercise bike! I tried out each of the programs. I was able to monitor my heart rate, rpm, distance, and calorie burn. I didn't pay much attention to the calorie burn because I'm more interested in building muscle.

The bike runs smoothly. It's probably about the easiest to operate of any exercise machine I have. I love it!

Negatives, if I have to list any, would be that it doesn't have arm motion.

Working out on it is fun! I use a variety of cycling videos, that I've also reviewed, to keep me motivated and keep up my cadence...Read more
