Buying Guide
Key considerations when selecting a 20-inch rear wheel include brake compatibility (disc, rim, or coaster), axle type (14mm chromoly vs. standard bolt-on), hub bearings (sealed vs. loose), rim width and profile (affecting tire compatibility and stability), spoke count (strength and weight), and overall weight. Disc-brake-compatible rims offer strong stopping power but require compatible hubs and rotors. For BMX riders, 14mm axles and sealed bearings improve durability under jumps. Bolt-on hubs are common on cruisers and some BMX setups for straightforward installation. Compare rim width to your tire choice to ensure proper fit and clearance.
Another dimension is tubeless versus tube-type tires. If you plan to run tubeless, confirm the rim bed is compatible and that a suitable tubeless setup is supported by your tire choice. For street and park riding, a robust, double-wall rim with a higher spoke count enhances durability and load-bearing capacity. Weight considerations matter for maneuverability and acceleration, while price and warranty can indicate long-term value. Lastly, confirm compatibility with your frame spacing (135mm or other), axle diameter, and brake mount type to avoid incompatibilities.
