Piston Pro X Add-On

Have a 2-bike Piston Pro X but need more capacity for you, your friends, or family? Upgrade to carry 3 or 4 bikes with the Piston Pro X 1-Bike or 2-Bike Add-Ons. Designed for seamless expansion, these Add-Ons install in minutes (the current record is 44 seconds). Simply attach the Add-On, connect the QuickConnect^™ pre-wired male-to-female wiring, and you’re ready to roll. The Add-Ons work specifically with the dedicated 2” hitch only.

Loading the Piston Pro X 3- or 4-bike hitch rack is effortless—even with one hand. Just press the OneTap^™ Piston levers, and the cradle arms automatically open into position, ready for your bikes.

The FastFit^™ Wheel Chock feature lets you adjust the rack on the fly to fit wheels from 18” to 29” in seconds, no tools required. These Add-Ons are designed specifically for a dedicated 2” hitch and carry forward the same exceptional features as the 2-bike Piston Pro X hitch rack.

With features like no frame contact, all-metal construction, semi-integrated cable locks, and premium materials like Genuine Kashima-coated struts and Tiger Drylac^® powder coating, the Piston Pro X Add-Ons are built to perform flawlessly for years while turning heads everywhere you go.

For heavier electric bikes, the 3-bike rack can handle up to 50 pounds per tray, and the 4-bike rack holds up to 40 pounds per tray. Pair it with our e-bike ramp for effortless loading and unloading. Expand your vehicle’s carrying capacity—and your circle of adventure buddies—with the Piston Pro X Add-Ons.
