Transform your hitch rack carrying capabilities with the Küat Piston Pro 1-Bike or 2-Bike Add-Ons giving you a 3- or 4-bike capacity. The user-friendly design makes attaching the additional trays to your hitch rack a no-brainer. Add riders faster than it takes to decide who gets to ride shotgun.

When you need a bike rack for your car, and you need to transport 3 or 4 bikes, the Küat Piston Pro 1-Bike and 2-Bike Add-Ons are designed to help you add riders to your 2-bike hitch rack in the blink of an eye.

Loading our 3 or 4-bike hitch rack is so easy you can do it with one hand. Prepare to enter the realm of bike-loading awesomeness with our mind-blowing, patented pneumatic OneTap Piston levers. Simply give those levers a tap, and watch as the cradle arms open automatically into position. The touchless arms grab the tires and avoid contact with the bike frame. The FastFit™ 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 hitch rack. No contact on the bike frame, all-metal construction, semi-integrated cable locks, and bombproof finishes. All of these 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 3-bike hitch rack will hold up to 50 pounds per tray, and our Piston® Pro 4-bike hitch rack will hold up to 40 pounds per tray. And we even have an e-bike ramp for making loading and unloading your electric bike a breeze.

Like all of our products, the Piston Pro Add-Ons are covered by our No Worries Limited Warranty, so you can rest assured your bikes are in good hands.

Expand your vehicle’s carrying capacity (and your circle of friends) with help from the Piston Pro Add-Ons.
