Piston® Pro X Add-On
When you need a bike rack for your car, and you need to transport 3 or 4-bikes, The Piston® Pro X 1-bike and 2-bike Add-ons are designed to help you add riders to your 2-bike hitch rack in a matter of minutes (the current record is 44 seconds). Simply install the Add-On and plug the QuickConnect™ pre-wired male-to-female wiring connections and the LED lights will sync automatically. Giving you enhanced visibility and peace of mind while en route to the trailhead.
Loading our 3 or 4-bike hitch rack is so easy you can do it with one hand. Simply hit the OneTapâ„¢ Piston levers and watch as the cradle arms open automatically into position. The FastFitâ„¢ Wheel Chock feature allows you to change the hitch rack on the fly to hold wheels from 18″ to 29″ in seconds, tool-free.
Of course, these Add-ons have some of the same amazing features as the 2-bike Piston Pro X hitch rack. Features like no contact on the bike frame, all metal construction, semi-integrated cable locks, and bombproof materials like Genuine Kashima coated struts and Tiger Drylac® powder coating. All features are designed to ensure your hitch rack not only functions flawlessly for years but drops jaws the whole time, too.
Transporting heavier electric bikes? Our Piston® Pro X 3-bike hitch rack will hold up to 50 lbs. per tray and our Piston® Pro X 4-bike hitch rack will hold up to 40 lbs. per tray. And, we even have an e-bike ramp for making loading and unloading your electric bike a breeze.
Expand your vehicle’s carrying capacity (and your circle of friends) with help from the Piston® Pro X Add-ons.
