The Kuat Piston SR is one of the most versatile bike racks available. Originally designed as a premium roof rack, the Piston SR can easily transform into a rugged hitch rack with the Piston SR Hitch Adapter, giving you the flexibility to carry bikes exactly where you want them.

With the hitch adapter installed, the Piston SR becomes a heavy-duty rack capable of carrying electric bikes up to 100 lbs, and it’s even approved for RV use when used with chassis-mounted hitch receivers (67 lb capacity per bike when used on RVs).

The modular design also allows you to mount the Piston SR in unique ways. Pair it with the IBEX truck bed rack mount to carry your bike along the side of your truck while keeping your hitch free, or install it on your van with 2" Round Bar Mounts for flexible rear mounting.

Engineered with premium materials, innovative strut technology, and tool-free adjustments, the Piston SR delivers smooth operation, exceptional durability, and secure bike transport for everything from lightweight road bikes to heavy e-bikes.
