# LifeSpan R5i Recumbent Bike Back Adjustment MX113
The LifeSpan R5i Recumbent Bike Back Adjustment (MX113) is a replacement fitness equipment part for the LifeSpan R5i recumbent exercise bike. It belongs to the bike’s back adjustment assembly and helps support the adjustment function of the seat back. If the original back adjustment component on your R5i is worn, damaged, or missing, this part may help restore the equipment without replacing the entire exercise bike.
Product Details and Benefits
This LifeSpan replacement part measures **10 3/8 inches in length**. The product is identified by the part number, SKU, and barcode **MX113**, making it easier to compare with the component currently installed on your bike.
Each part is carefully inspected by skilled technicians before shipment. This inspection helps confirm that the used fitness part meets the seller’s standards for performance and safety. Because this is a used or previously installed component, its appearance may vary slightly from the product image. These differences can include surface marks, finish changes, or other signs of prior use. The seller states that the part supplied will match the exact model and part listed.
Replacing a specific adjustment component can provide a practical alternative to purchasing a complete replacement machine. It may also help extend the useful life of your LifeSpan R5i recumbent bike. Choosing a used fitness equipment part can reduce replacement costs and supports reuse by keeping serviceable components out of landfills.
Compatibility and Applications
The **MX113 Back Adjustment** is listed for the **LifeSpan R5i recumbent bike**. It is intended for use as a replacement part within the R5i back adjustment system. The product information does not confirm compatibility with other LifeSpan recumbent bikes, upright bikes, treadmills, or fitness equipment, so do not assume that another model will accept this part.
This component may suit a repair project, equipment refurbishment, or maintenance work on a LifeSpan R5i where the existing back adjustment part requires replacement. It is especially relevant when you want to repair the bike using an individual component rather than replace the complete unit.
Why Choose This Product

Its listed length provides an important measurement for comparison, while the clearly marked part number helps reduce the risk of ordering an unrelated component.

Using the correct replacement component can help you maintain an existing LifeSpan recumbent bike and avoid unnecessary equipment disposal. It also allows you to source a single part for a targeted repair.
