How to fix your Lamar exercise cycle when resistance won't change

If pedal resistance sticks on one setting, the resistance motor could be defective. Many exercise cycles offer workout programs that vary resistance automatically during the routine. If resistance during the uphill climbs on a pre-programmed workout feels the same as the downhill treks, try manually changing the resistance. If you can change resistance manually, then you'll likely need to replace the console.

Most exercise cycles use battery power to change resistance, so checking for DC voltage going to the resistance motor is safe and easy. If batteries power your exercise cycle's control system, use a multimeter to measure voltage at the resistance motor when you manually adjust resistance on the console. Replace the console if it doesn't send voltage to the resistance motor when you manually change resistance. Replace the resistance motor if it doesn't run when getting voltage from the console.

Top repair parts for Lamar exercise cycles

• Resistance motor. The resistance motor changes the distance of the C-magnet from the flywheel to adjust the pedal resistance.
• Tension cable. The tension cable attaches to the C-magnet and adjusts the distance between the C-magnet and the flywheel to vary the resistance.
• Reed switch. The reed switch detects a magnet attached to the rotating crank arm pulley to sense speed and sends the speed signal to the console.
• Console. The console controls pedal resistance and displays time, distance, resistance level and other settings and readings.
