2025 Kuat Piston® Pro X

The Piston Pro X hitch rack features genuine Kashima-coated pneumatic tire arms that keep your bike secure, and your paint pristine. With LED taillights for enhanced rear visibility and on-road safety, it's the bike rack designed for most bikes, even electric bikes weighing up to 67 pounds.

Description

Meet the Piston Pro X hitch rack. This all-metal bike rack can safely transport bikes and electric bikes weighing up to 67 lbs. per tray. With just one tap, the pneumatic arms open wide and adjust to fit your bike tire perfectly, with no contact with the frame.

And you won't need any adapters or tools to fit small to beefy tires. Just squeeze and slide the adjustable wheel chocks to hold 18"-29" tires.

The integrated LED taillights synchronize seamlessly with your car, truck, SUV, or RV, providing enhanced rear visibility and on-road safety.

For added security, the Piston Pro X includes a hitch lock and a semi-integrated 12mm cable lock to keep your bike locked up tight-and looking sharp while doing it.

Oh, and yes, we went there: a touch of Kashima adds unmatched beauty and durability.

These features culminate in a bike rack designed, built, and tested to push the envelope and provide you with unparalleled ease of use, peace of mind, and lasting value.
