The UBK 615 is Precor’s lowest-priced upright exercise bike for home settings. Priced under $2,500 it’s much cheaper than others from this brand yet also provides commercial quality workouts. Overall this bike is a wise buy if you don’t need very strong resistance; its top challenge is 500 watts while the pricier bikes reach up to 750 watts. But whichever resistance level you choose, Precor cycling is super smooth. You can select from three riding positions – cruising, road racing, and upright – and can adjust the seat to get a custom fit. For practical home use the Precor 615 measures just 46″ long and 21″ wide. It doesn’t require a power cord (the battery is recharged by user energy) and has wheels attached for easy repositioning after workouts.

Precor Workout Programs

Six workout programs are provided on the UBK 615 monitor, which is called the P10. The program titles are Heart Rate, Hill Climb, Interval, Manual, Random and Weight Loss. Also available is Quick Start. Quick Start lets you begin a workout with just the push of a button.

The electronic readouts are calories, Distance, Speed, Watts, Heart Rate, SmartRate® (heart rate zone), Profile, Resistance, RPM, Time and Percent Complete.

Data can be shown in the US Standard and metric systems. Language choices are English, Dutch, German, Spanish, French, Portuguese, Italian and Romanized Russian.

Precor UBK 615 Features

SmartRate on select Precor bikes helps you keep aware of your exertion level. It indicates three workout zones: cardio, fat burn and peak. Your weight and age are taken into account for accurate feedback. Your heart rate can be monitored with touch sensors on the handlebars or with a wireless chest strap sold separately.

The 615 and other Precor upright bikes are low impact or gentle on your knees. This is because of overall smooth engineering and the bike saddle’s smart positioning of your body over the pedals.

The P10 console can be adapted for high tech entertainment: Optional upgrades are a 15″ personal viewing screen and iPod/iPhone compatibility.

The console is powered by a rechargeable battery that harnesses user energy. Using this self-powered system you can avoid adding to energy bills and still see a workout summary for 30 seconds after your session. If you would like to view data for longer, or if you won’t use the bike often enough to keep it charged from your activity, then the machine can be adapted to use a power cord.

The Precor 615 bike warranty package includes:

– Frame: Lifetime
