Eastern Bikes Atom Series 20-Inch BMX Wheel (Rear 14mm Axle)
The Eastern Bikes Atom Series rear wheel is designed for BMX riders who need a sturdy rear wheel with a 14mm chromoly axle. The 36mm wide rim adds lateral stiffness, improving wheel durability during aggressive riding. Best for riders who perform park tricks or heavy rail slides and want reliable bite from a true BMX rear setup. A potential limitation is the single rear axle standard; ensure your frame matches 14mm axles before purchasing.
Exceedhub 20″ Wheelset (Front & Rear)
This wheelset offers a complete upgrade with front and rear wheels built to withstand diverse BMX riding conditions. With 12-gauge spokes and double-wall aluminum rims, it emphasizes durability and consistent engagement, making it well-suited for ramp and street sessions. Choose this if you want a ready-to-install pair, but note the heavier build may feel slightly stiffer on technical balance-focused trails.
DONSP1986 20 Inch Rear Wheel Rim 12 Gauge
The DONSP1986 rear rim is built with heavy-duty 12-gauge aluminum and a double-wall design, creating a robust rear wheel suitable for disc brake setups. It’s a strong option for riders who rely on rear-wheel strength for hard landings and high-speed sessions. Best for riders who want a resistant, long-lasting rear rim, with the caveat that it’s specifically a rear rim and may require compatible components for full wheel assembly.
POLSO BMX Wheelset 20″ 36H
The POLSO wheelset targets BMX enthusiasts seeking reliable performance with a 9T rear hub featuring 120-click engagement. Designed for street, park, and dirt riding, this wheelset emphasizes quick response and solid acceleration. Best for riders who want easy engagement and a balanced setup, but consider hub engagement preferences if you ride mixed terrains where micro-adjustments matter.
Hiland 26″ Rear Wheel Rim (Alloy)
This Hiland rear wheel rim is a versatile alloy option for larger wheel setups, suitable for disc brake compatibility and multiple speeds. Best for riders who use 26-inch wheels or need a rear rim option that can handle a range of tires. Avoid this if you require a 20-inch BMX-specific rear rim, as it targets broader mountain-bike dimensions.
Buying Guide
- Rear axle type matters: Check whether your frame and hub use 14mm, 12-gauge, or another standard to avoid compatibility issues.
- Brake compatibility: Disc brake rims may require specific hubs and calipers; ensure your bike’s braking system matches the rim’s design.
- Rim width and strength: A wider rim adds lateral stiffness and durability, useful for aggressive tricks and landings.
- Wheelset vs. rim only: Decide if you want a complete wheelset (front and rear) for convenience or a single rear rim for upgrading an existing setup.
- Spoke count and hub engagement: Higher spoke counts increase durability; quick-engaging hubs improve trick response on ramps and street work.
- Weight vs. durability: Heavier rims can be more durable; lighter rims facilitate speed and manual tricks but may be less forgiving on rough surfaces.
