# FreeMotion SFEX04012.2 250U Upright Bike Seat Adjustment Pin Knob (MX414)

## Product Introduction

The FreeMotion SFEX04012.2 250U Upright Bike Seat Adjustment Pin Knob is a preowned replacement part for the seat adjustment system on a FreeMotion 250U upright exercise bike. This knob helps secure the seat adjustment pin so the seat can remain in the selected position during use. If the original knob is missing, damaged, or no longer usable, this replacement part can help restore the bike’s seat adjustment function.

## Product Details and Benefits

This product is identified as the FreeMotion SFEX04012.2 250U Upright Bike Seat Adjustment Pin Knob. It belongs to the seat adjustment assembly and works with the pin used to set the saddle height or position. The knob provides a practical way to handle and secure that adjustment hardware during setup.

As a preowned fitness equipment part, this item offers a way to replace a specific component without replacing the entire upright bike or seat adjustment assembly. Replacing only the damaged or missing knob may help return the equipment to its intended configuration and keep the bike available for regular workouts.

Each part has been carefully inspected by skilled technicians for performance and safety before sale. Because this is a used part, it may show signs of previous use. The product photos are for reference only, and the appearance may vary slightly from the item received. The seller carries multiple units, but each one matches the listed model and part.

This replacement knob can suit repair work, maintenance, refurbishment, or the restoration of a FreeMotion upright exercise bike. It may also be useful for fitness equipment technicians, repair shops, gyms, and individuals maintaining a home exercise machine.
