FIT Bike Co OEM 12″ Wheelset

The FIT OEM 12″ wheelset is a complete wheel set designed for 12″ BMX bikes. Featuring a sealed cassette rear hub with 9-tooth driver and unsealed front hub, this wheelset provides a replacement or upgrade option for entry-level 12″ complete bikes. Both wheels use 16-hole rims with 3/8″ male axles.

Key Features

• Sealed cassette rear hub – sealed bearing cassette hub reduces maintenance and provides smoother rolling compared to freewheel designs, with instant engagement when pedaling
• 9-tooth driver – smaller driver allows lower gear ratios for easier pedaling and quicker acceleration, ideal for younger riders on 12″ bikes
• 16-hole rim construction – lower spoke count reduces weight while still providing adequate strength for the lighter loads typical on 12″ bikes
• 3/8″ male axles front and rear – standard axle size for entry-level and OEM bikes, compatible with most 12″ frames and forks
• Right-hand drive – drivetrain runs on the right (chain) side of the bike, the standard configuration for BMX bikes

Compatibility and Ideal Use

This wheelset is designed for 12″ BMX bikes with 3/8″ dropouts on both front and rear—verify your frame and fork dropout sizes before purchasing. The unsealed front hub requires more frequent maintenance than sealed designs but is typical for entry-level complete bikes. Best suited as replacement wheels for damaged stock wheelsets on 12″ complete bikes or as an upgrade for bikes with lower-quality freewheel rear hubs. The cassette rear hub provides better performance than freewheel designs but the unsealed front hub is best for light recreational use rather than aggressive riding.
