This complete 21x1.6 front and 18x2.15 rear wheelset is the ultimate performance upgrade for your Ultra Bee. Engineered for riders seeking maximum traction, stability, and strength on aggressive off-road terrain, this setup delivers a significant improvement over stock wheels.

The taller 21-inch front rim enhances rollover capability and steering precision, while the 18-inch rear rim provides better impact absorption and opens up more tire options with deeper tread—giving you superior grip during climbs, corners, and high-load situations.

Built using high-quality, lightweight materials that are stronger than OEM, this wheelset offers a noticeable boost in control, durability, and overall ride quality—perfect for everything from rugged trails to technical rock sections.

As a direct bolt-on replacement for the stock Ultra Bee wheels, the 21x1.6 / 18x2.15 combo is the perfect upgrade for serious riders who want to push their bike harder, faster, and with more confidence.
