• The Kuat Piston ION is the e-bike rack built for adventure, engineered to handle today’s heaviest rides while delivering the style and innovation Küat is known for. Constructed from mostly aluminum, the ION blends premium materials and features, ensuring unmatched performance.  

  Specifically designed for heavy e-bikes yet versatile enough to work with almost any bike, the ION carries up to two bikes at 100 lbs each with zero frame contact. A new Foot Pedal Lock and PedalPivot™ system make folding the rack up or down simple and intuitive, while the FastFit™ tool-free wheel chock system ensures quick adjustment for a wide range of wheel sizes.

  The Piston ION isn’t limited to paved roads. It’s approved for RV use and off-road rated, so you can haul your e-mountain bikes deep into the backcountry or hit gravel routes with confidence. For RV setups, each tray supports up to 80 lbs per bike, while off-road use allows for 50 lbs per bike. With a 2” hitch-only design, adjustable wheel stabilizers for a secure bike fit, and fender compatibility, it adapts to the demands of riders.

  Packed with premium details that elevate it beyond standard racks, the ION includes a semi-integrated 12mm high-strand cable lock, stainless steel barrel hitch lock, and an aluminum ramp for easy e-bike loading and unloading. Optional accessories like the ION Light Kit and License Plate Mount keep you visible on the road. Finished with a powder coat and backed by our No Worries Limited Warranty, the Piston ION is built to last as long as your adventures.

  Perfect for: Cargo e-bikes, e-MTB riders, road trip travel, and riders who go off the grid or around the block.
