The 8x8 screen displays information to the user during use, including time, speed, distance, calories burned, wattage, resistance level and program profile. 5 customizable programs are also included for a total of 17 step-by-step regimes, suitable for riders of all ages. Heart rate is monitored directly and accurately through the unit's "Pulse Grips" that are installed in the handlebars, with an added pulse recovery program that measures how quickly the user returns to a resting rate. The 1615 utilizes a friction-free magnetic belt-drive system that provides a smooth and quiet workout, with 16 levels of resistance available for beginner to expert-level riders. A fully adjustable seat and an oversized pedal design further contribute to the versatility of the machine, safely accommodating users up to 250 pounds. Front-mounted transport wheels are included for fast transportation, and an AC adapter is provided for the display and resistance systems.
