NordicTrack C1650

Controls: The incremental, speed-control buttons are oriented as expected with the increase button on the top or right-hand side. They are positioned appropriately being right next to one another. The button size is considered very good making it somewhat easy to operate while exercising. An alternative set of quick speed-controls provide the ability to select every, whole-number speed, using a complete set of control buttons. The incremental, incline-control buttons are oriented as expected with the increase button on the top or right-hand side. They are positioned appropriately, being adjacent to one another. The button size is considered excellent, making it easy to operate while exercising. An alternative set of quick incline-controls provide the ability to select every-other, whole-number incline using a limited set of control buttons. Display: The monitor displays white characters on a black colored background. The size of the characters showing the "speed" is considered poor and the size of the characters showing "incline" is considered poor. Exercise statistics are presented in multiple windows with some statistics sharing the same window. Programs: This machine comes equipped with 43 built-in exercise programs. A list of programs is convenienty shown on the console. A graphical illustration of each program's exercise profile is shown on the console. Ergonomics: The step-up height to the running deck is 10.75 inches from the floor. This machine has a front handgrip, which provides less grip area than a full handrail. A partial side-handrail provides both security and easy access. Exercise: The minimum incline for this machine is -1.1 percent. The maximum incline is 14.6 percent. The manufacturer-stated, top speed is 12 mph. A top speed of 12 mph was measured. Construction: This machine features a motor with a 3.6 hp rating. The lack of floor levelers means there is no built-in leveling feature. Performance on our durability test - simulating a half-year of usage - was very good, showing only minor signs of wear. Safety: The "stop" button size was considered excellent. The magnetic style safety-key disengaged without issue when a user approached the end of the running belt, which stopped the motor and running belt as expected. After the safety key was removed from its receptacle, the running belt coasted to a stop from a speed of 6 mph, in 6.4 seconds. The average stopping time for all tested treadmills is 5.7 seconds. When walking within reach of the control console, the motor housing which resides at the front of the running belt, created some interference with a user's feet, but it was infrequent.

The NordicTrack C1650 is part of the Treadmills test program at Consumer Reports. In our lab tests, Treadmills models like the C1650 are rated on multiple criteria, such as those listed below.

Ergonomics: Ergonomics considers how well the machine accommodates the needs of users and includes belt size, foot-rail design and handgrip design.

Construction: Construction considers aspects that impact quality like the motor and related components, running deck and the results of our durability tests.

Ease of use: Ease of use considers the ease of using the controls, functions, programs and reading the display.
