Buying Guide
Key purchase considerations
- Axle and hub standards: Common BMX rear wheels use 14mm chromoly axles or 3/8″ bolts. Ensure the axle type matches your frame dropout width and brake mounting.
- Sprocket vs freewheel compatibility: If you expect a multispeed setup, choose a freewheel hub (6-11 speeds) or a cassette-compatible option. If you prefer simple single-speed gearing or a coaster brake, verify that the wheel supports that configuration.
- Braking system: Disc brake-ready rims and hubs differ from coaster brakes. Consider your preferred braking method and whether your frame supports disc rotors or coaster back-pedal braking.
- Rim and spoke design: 36H, 48H, and higher spoke counts affect strength and weight. Heavier spokes (like 144-spoke wheels) offer durability for street and park abuse but add weight.
- Rim width and tire compatibility: 20 x 1.75 tires are common, but wider “fat” tires require larger clearance. Check inner rim width and tire clearance with your frame and brakes.
- Material and durability: Aluminum rims are standard; magnesium alloys reduce weight but require careful handling. Sealed or semi-sealed hubs improve longevity in rough riding.
- Weight and installation: Quick-release hubs offer convenience; bolt-on axles provide security. Confirm your frame’s dropout compatibility and the wheel’s overall weight.
Comparisons and suggestions
- Disc brake vs coaster brake: Disc brakes offer controlled stopping power and consistent performance in wet conditions, while coaster brakes are simple and maintenance-light but can limit braking versatility.
- Freewheel vs cassette: Freewheel hubs are common on single- and some multispeed builds and are more compatible with older gear selections. Cassette hubs are standard for modern, wide-range gearing but require compatible hubs and derailleurs.
- Wheel strength vs weight: Heavier wheels with more spokes (e.g., 144-spoke chrome sets) are sturdier for impact-heavy riding but add weight. Lighter magnesium or aluminum wheels improve acceleration but may tolerate less abuse.
- Fit and clearance: Always verify frame clearance for tire width, rotor size, and sprockets. A 20-inch wheel can vary in overall diameter depending on tire choice and rim width.
When choosing, align the wheel with your riding style—downhill-leaning park riding may benefit from heavier, more durable wheels; casual street cruising might prefer lighter builds with simpler sprocket setups. A thorough check of compatibility with your frame, brakes, and intended gearing will ensure the wheel delivers reliable performance across different environments.
