Product Introduction
The LifeSpan R3i Recumbent Bike Heart Rate Sensor Left Arm Rest is a replacement heart rate sensor assembly for the left armrest of a LifeSpan R3i recumbent exercise bike. This part helps the bike detect heart rate through the armrest contact area during a workout. If the original left-armrest sensor is missing, damaged, worn, or no longer functioning correctly, this component may help restore the bike’s heart rate monitoring feature.
This product is listed under part number and SKU **SS105**. It is intended for customers repairing or maintaining a LifeSpan R3i recumbent bike rather than replacing the entire machine.
Product Details and Benefits
The SS105 includes the **heart rate sensor for the left arm rest**. The sensor forms part of the bike’s built-in heart rate monitoring system and supports pulse readings when the user grips the appropriate contact area during exercise. Replacing the affected component can help maintain the bike’s original heart rate tracking function.
Each part is carefully inspected by skilled technicians before shipment. This inspection helps confirm that the component matches the listed model and part type. The item comes from used fitness equipment stock, making it a practical choice for repairing an existing machine and extending its usable life.
Using a replacement part can also help reduce unnecessary equipment waste. Instead of discarding a recumbent bike because of one damaged component, owners can replace the affected sensor and continue using the equipment when the rest of the machine remains suitable for service.
