99% METAL - 100% SERIOUS
The Piston Pro is built to last, with an all-metal body, stainless steel hardware, and automotive-grade components throughout. It’s not just good-looking—it’s rugged, stable, and ready to handle whatever the road throws at it. From daily commutes to all-out road trips, this rack is made to go the distance.
LOAD FAST - LOCK FIRM
The patented OneTap™ system opens the cradle arms with a single press—automatically adjusting to your tire without touching your frame. The FastFit™ wheel chocks slide tool-free to fit 18"–29" wheels in seconds. It also supports tires up to 5” wide and wheelbases up to 53”, no adapters required.
BUILT FOR E-BIKES
Each tray on the 2” Piston Pro supports up to 67 lbs., making it ready for most electric bikes straight out of the box. Touchless arm retention protects sensitive frames and paint jobs, while a heavy-duty 12mm cable lock keeps things secure while you're away. Peace of mind? Included.
STABLE - SIMPLE - SECURE
The Flatlock™ cam system ensures a rock-solid, wobble-free connection to your 2” hitch, while the stainless steel hitch lock adds tamper resistance. Fold or lower the rack easily with the foot-operated pivot lever—no need to put your bike down. Every detail has been considered, and every feature earns its place.

Featuring patented OneTap™ pneumatic arms, FastFit™ tire chocks, and bombproof materials throughout, it’s built for serious riders and serious loads—up to 67 lbs. per tray.
