\# Matrix Fitness U-30-02-F Upright Bike Magnetic Flywheel Brake Mechanism GP87

The Matrix Fitness U-30-02-F Upright Bike Magnetic Flywheel Brake Mechanism is a preowned exercise-bike component identified as GP87. It belongs to the magnetic flywheel brake system used on the Matrix Fitness U-30-02-F upright bike. This part may suit equipment owners, fitness-equipment technicians, and repair businesses looking for the correct brake mechanism for servicing a compatible Matrix Fitness bike.

## Product Details and Benefits

This product is a magnetic flywheel brake mechanism for an upright exercise bike. The component forms part of the bike’s resistance and braking assembly, which interacts with the flywheel during operation. When the original mechanism becomes damaged, worn, or unsuitable for continued use, a matching replacement component can help support repair and maintenance work.

The product is sold under the following identification:

\- \*\*Brand:\*\* Matrix Fitness  
\- \*\*Product:\*\* U-30-02-F Upright Bike Magnetic Flywheel Brake Mechanism  
\- \*\*Part identification:\*\* GP87  
\- \*\*SKU:\*\* GP87  
\- \*\*Barcode:\*\* GP87  
\- \*\*Condition:\*\* Preowned  
\- \*\*Equipment type:\*\* Upright exercise bike  
\- \*\*Brake system:\*\* Magnetic flywheel mechanism

Because this is a preowned part, its condition may differ from that of a new component. Buyers should inspect the available product photographs and review the listing details carefully before ordering. The product page does not provide additional information about the material, dimensions, finish, electrical specifications, or included hardware.

## Compatibility and Applications

The Matrix Fitness GP87 magnetic flywheel brake mechanism is associated with the \*\*Matrix Fitness U-30-02-F upright bike\*\*. It is intended for use with the brake and resistance assembly of that equipment model rather than as a universal exercise-bike part.

This component may be considered for:

\- Repairing a Matrix Fitness U-30-02-F upright bike  
\- Replacing a matching magnetic flywheel brake mechanism  
\- Supporting workshop maintenance or equipment refurbishment  
\- Keeping an existing Matrix Fitness exercise bike in service

Compatibility should be confirmed before purchase. Upright bikes can use model-specific brackets, mounting points, and brake assemblies, so a similar-looking part may not fit another Matrix Fitness model or a different brand of exercise bike.

## Why Choose This Product

Choosing the correct model-specific mechanism can make repair work more straightforward than adapting an unrelated component. The GP87 identification gives buyers a clear reference when comparing the part with the existing assembly or service records. Its preowned condition may also make it suitable for customers sourcing an original used component for an older or previously serviced Matrix Fitness bike.

This listing focuses on the brake mechanism itself. It does not confirm that additional mounting hardware, cables, tools, or other bike components are included.

## Before You Buy

Confirm that your equipment is a \*\*Matrix Fitness U-30-02-F upright bike\*\* and compare the existing brake mechanism with the product images and GP87 identification. Check the part number, mounting arrangement, and overall design before ordering. If your bike has a different model designation, contact a qualified fitness-equipment technician or Matrix Fitness service professional to verify compatibility.

This is a \*\*preowned Matrix Fitness GP87 magnetic flywheel brake mechanism\*\*. Dimensions, warranty details, installation instructions, and package contents are not specified in the available product information.
