FIT Bike Co OEM 18″ BMX Wheelset

FIT Bike Co OEM 18″ BMX Wheelset

The FIT OEM 18″ wheelset is a complete front and rear wheel package designed specifically for 18″ BMX bikes. Built with 36-hole rims and a sealed cassette rear hub, this wheelset provides reliable performance for younger or smaller riders transitioning into more technical riding. The components are sized and spec'd for durability under the demands of park, street, and beginner-to-intermediate trail use.

Key Features

• 18″ diameter, 36-hole rims – Smaller wheel size suited to 18″ frame geometry, with 36 spokes providing strength and impact resistance for aggressive riding
• Sealed 14mm male rear axle – The sealed bearing design keeps dirt and moisture out for longer hub life and smoother rolling with less maintenance
• 9T cassette driver, right-hand drive – Cassette system offers quicker engagement and less pedal kickback compared to freewheel setups, mounted for right-side drive configuration
• 3/8″ male front axle, unsealed – Standard front hub size compatible with most 18″ forks; unsealed bearings reduce cost while remaining serviceable for routine maintenance

Technical Specifications

• Wheel size: 18″
• Rim: 36-hole
• Rear hub: Sealed bearing, 14mm male axle
• Cassette driver: 9T, right-hand drive (RHD)
• Front hub: Unsealed bearing, 3/8″ male axle

Compatibility and Ideal Use Cases

This wheelset is designed for 18″ BMX frames with cassette-compatible rear dropouts and standard 3/8″ front fork ends. The 14mm rear axle requires frame dropouts that accept 14mm hardware or compatible adapters. It's ideal for younger riders progressing beyond entry-level bikes or anyone riding an 18″ setup who needs a durable, low-maintenance wheelset for park and street riding. The sealed rear hub is particularly useful for riders in wet or dirty conditions where unsealed hubs would require frequent servicing.
