Trotter was founded in 1973 by Edward Trotter. The company manufactured high-end treadmills. In 1997, Cybex merged with Trotter. The Trotter brand name was eventually dropped; all Trotter treadmill models have since been discontinued. The 535 was originally introduced in 1998. It was recalled twice, in 2003 and 2007. Cybex no longer provides support or stocks parts for Trotter treadmills.
The Trotter 535 is 69 inches long, 30 inches wide and 56 inches tall. It weighs 250 lbs. This is a large, heavy treadmill. It does not fold-up and cannot be moved easily. The height from the floor to the walking deck is 4.5 inches. The running belt is 52 inches long and 18 inches wide. In December 2010, newer Cybex treadmills have larger, 60-by-20 inch decks. The maximum user weight for the Trotter 535 is 350 lbs.
The digital console displays feedback on your current workout session. It monitors the incline, time, calories burned per hour, pace in minutes and seconds, speed, distance, total calories burned and heart rate. Select either "Manual" or "Program" mode on the Trotter 535. In manual mode, you control the incline and speed settings using the buttons on the console. In program mode, you select one of 11 built-in programs that change the speed and incline at preset intervals.
The 2-horsepower motor on the Trotter 535 can handle speeds up to 10 mph. The power ramp inclines up to a 12 percent grade. Adjust the incline or speed with the press of a button. The running deck is cushioned to reduce the shock to your joints. The Trotter 535 can monitor your heart rate, but you must purchase a compatible Polar chest transmitter separately to use this feature.
In October 2003, the U.S. Consumer Product Safety Commission announced a recall of several Cybex treadmills, including the Trotter 535. The treadmills were a fire hazard due to overheating under the motor hood. In October 2007, the Trotter 535 was included in a second recall of Cybex treadmills. According to the U.S. Consumer Product Safety Commission, the wire nuts used to repair the previously recalled models was not installed properly and caused treadmills to overheat resulting in another fire hazard.
