Kuat Hitch Bike Racks - KU89SR

Highlights

  • Load Heavy E-Bikes with Ease: Included aluminum ramp saves lifting effort for heavy e-bikes.
  • Keep Paint Pristine: Zero-frame contact design secures wheels only, preventing scratches.
  • Haul 2 Bikes Securely: Handles 100 lbs per tray (80 lbs RV / 50 lbs off-road) for confident travel.
  • Fit Any Tire or Frame: FastFit wheel chocks adjust for 18"–29" wheels and up to 4.8" tires.
  • Reach Gear Quickly: Foot-pedal tilt lets you lower or lock the rack without unloading bikes.
  • Store Compactly: Folds and stows easily in your truck or bed when not in use.

Features to know about

Effortless Loading for Heavy E-Bikes: Built-In Aluminum Ramp

Lifting 60- to 75-lb e-bikes can be a strain, but the Kuat Piston ION makes it simple. The included aluminum ramp lets you roll each bike into place instead of hoisting it overhead. Once loaded, the platform keeps both bikes balanced and ready to travel without fuss.

Secure Hold Without Frame Contact: Tire-Only Mounting System

Paint jobs and carbon frames stay safe thanks to the wheel-mount design. The Piston ION holds each bike by the tires, not the frame, so nothing rubs or scratches in transit. Fender-compatible arms telescope to the right length and lock in tight for a clean, no-touch fit.

Stable Ride on Any Road: Built for E-Bikes, RVs, and Off-Road Use

From highways to gravel stretches, this rack is rated to handle it all. It carries 100 lbs per tray in standard use, 80 lbs per tray on RVs, and 50 lbs per tray off-road. That strength means you can haul heavy e-bikes, fat-tire rigs, or tough downhill builds without second-guessing stability.

Quick Adjustments for Any Setup: FastFit Wheel Chock System

Bike sizes vary, but setup shouldn’t be a hassle. The FastFit wheel chocks slide and lock into place to fit 18"–29" wheel sizes, tires up to 4.8" wide, and wheelbases up to 57". Switching between bikes is fast and tool-free, letting you spend more time riding and less time tinkering.

Compact Storage When the Ride’s Over: Easy to Stow Away

When the trip’s done, the rack stores cleanly in the bed or corner of your garage. The foot pedal lock makes folding and handling simple, and the sandy black finish keeps it looking sharp after every haul.

It arrived a day early and I have put the rack together. It assembled nicely. I will be loading bikes on in the next few days. Thank you for a punctual delivery. It arrived in good condition.



by:

The rack is very study and easy to assemble. The velcro straps for the fat tires need to be a few inches longer otherwise I'm impressed with the bike rack so far. The true test will be behind my 5th wheel!



by:

I have purchased many bike racks and this built to last a lifetime. I play to use it for our ebikes. Could not purchase a finer product. It came quickly and was supper easy to setup.



by:

The rack has great fit & finish. Easy to assemble and everything is included, ramp & lock. Tried it on our truck and will test it on our RV next. So far so gpod!!



by:

Rating would have been excellent if Kuat had incorporated the 8mm wrench for tightening to the hitch. That wrench comes comes with and is stored in the NV 2.0.



by:

Delivered promptly without damage !! Easy to assemble. You will need a torque wrench for 10 N. and 40Lbs with hex fittings. The rack itself has a nice black finish. The arms move easily. It does come with a cable lock. I would purchase again.

  • Which Hitch Is Best for Carrying E-Bikes and Light Towing with a 2021 Jeep Cherokee?
    Hello Sadie, Thanks for writing in. For your 2021 Jeep Cherokee, I'd recommend going with a Class III hitch with a 2" receiver since you're planning to carry two e-bikes and may eventually tow a small boat trailer or lightweight camper. My top recommendation would be the etrailer hitch # e73ZR. Another great option is the Curt hitch # C13395. The two hitches are very similar in capacity and fit, and both will work great for carrying e-bikes or handling light towing duties. The main difference...

  • Recommended Bike Rack and Dual Hitch Adapter for a Class A Motorhome
    Hey Gail, thanks for all of the information and welcome back! You've done your homework really well and I do agree the Kuat Piston ION E-Bike Platform Rack item # KU89SR is going to be the best option. The Piston ION item # KU89SR being a wheel mount style means you won't have to worry about frame damage on your carbon bike. Even with the reduced 80 lbs weight capacity of being mounted on your class A it's still strong enough for your 50 lbs e-bike. For a dual receiver adapter, I recommend...

  • Can Kuat Piston ION Be Used On 5th Wheel Hitch With Frame Mounted Hitch
    Hey Daniel! The Kuat Piston ION E-Bike Platform Rack # KU89SR can be used on trailers as long as the hitch is attached to the chassis/frame. Since you have a frame mounted hitch on your 5th wheel it is compatible and will work well. The bike capacity is reduced to 80 lbs per tray when used on a trailer, and Kuat also requires the Fender Strap Kit # KU43VR to help keep the bikes secure during travel. What kind of 5th wheel and e-bikes do you have?

  • Kuat Piston ION Bike Rack Clearance for Travel Trailer with Rear Spare Tire and Fendered Bikes
    Hi Guy, thank you for reaching out and for providing all those details. Based on the information you've shared, the Kuat Piston ION E-Bike Platform Rack part # KU89SR will work very well for your setup. The closest part of the rack sits about 14-1/4 inches from the hitch pin hole, so with the spare tire mounted on the rear bumper and adjustable side to side, you will have the clearance needed. From what you've described, the travel trailer's hitch is attached to the frame, not the bumper...

  • Availability of Kuat Piston ION E-Bike Platform Rack With Lights
    Hey Glenn! The Kuat Piston ION E-Bike Platform Rack # KU89SR does not have a version that comes with lights out of the box. The lights are available separately as the Light Kit for Kuat Piston ION E-Bike Platform 2-Bike Rack # KU29SR. These are designed to fit the ION and are powered via the 4-way on your vehicle. What kind of bikes are you carrying?

  • What Class Hitches Will The Kuat Piston ION Bike Rack KU89SR Work With?
    Hi Will! The Kuat Piston ION E-Bike Platform Rack for 2 Bikes w/ Ramp - 2" Hitches - Sandy Black # KU89SR will fit any 2" receiver, but you do want to be aware of the tongue weight capacity of that hitch. Class 3,4, and 5 hitches are fine and you are good to go, but there are some Class 2 hitches with 2" receivers as well. These will typically have 200 pounds of tongue weight capacity and can be used with this rack, but with the rack weighing 68 pounds, you will only have 132 pounds available...

  • Can Kuat Piston Pro Carry Veloctric Nomad 2x
    Hey Tom, you can definitely use the Kuat Piston Pro part # KU89SR with your Veloctric Nomad 2X bike but you will need the fender strap kit part # KU43VR which was designed for bikes just like yours that have fenders. Check out the attached picture to see what this looks like installed on a bike just like yours. Looks like you just ordered the rack the other day but not the strap kit, is that correct?

  • Kuat Piston ION Fit for Specialized Vado with Fender and Required Wheel Straps
    Bruce, Yes, that will work with your Specialized Vado 5.0, and the Kuat Piston ION part # KU89SR is actually built to handle bikes with fenders like yours. You can position the rear piston below the fender, but you will need to use the Kuat Fender Straps, part # KU43VR, to properly secure the wheel without putting pressure on the fender. That is really the key to making this setup safe and solid. The arms should always contact the tire, not the fender, and the fender straps are what...

  • Will Kuat Piston ION E-Bike Rack part # KU89SR Clear Rear Spare of Jeep Wrangler
    Hey Phil, yes the Kuat Piston ION E-Bike Rack part # KU89SR will fit the hitch you have installed on your 2019 Jeep Wrangler and will clear the rear spare as this bike rack has 14-1/4 inches from the center of it's hitch pin hole to the nearest part of the rack which is more than enough as we have found to clear Wrangler spares. This has the needed weight capacity for your 70 lb bikes too. This is also a really nice bike rack that you will really love so you'll be really happy with it....

  • Best Bike Rack For Carrying Tow Velotric Fold 2 Plus E-Bikes With Front And Rear Fenders
    Hello Kelley, thanks for reaching out. While the Kuat Piston ION # KU89SR is a very solid rack, I have concerns about the rear fender on the Velotric Fold 2 Plus bike obstructing the wheel mount. With 20" wheels it would be pretty tight. The luggage rack would easily clear, but I am not confident about that fender clearance, so the best bet will be to go with something different. That said, what I recommend is the Thule Epos Bike Rack # TH99XE. The main reason is the rack uses an adjustable...

  • Does Ramp of Kuat Piston ION E-Bike Rack Store on Rack When Not in Use
    Hey David, welcome back! The ramp of the Kuat Piston ION E-Bike Platform Rack # KU89SR that you referenced does not store on the bike rack. You'd need to put it in your vehicle when travelling. We have other e-bike racks like the Thule EasyFold XT part # TH903202 which does have the ramp store on the bike rack when not in use if that's your preferernce. What e-bikes do you have?

  • Solution for 2026 Ford Bronco to Carry Kuat Piston ION Bike Rack
    Hey Buddy, thank you for all of the details on your setup! Based on everything your best option is go replace your hitch with the TowSmart # TS46VR instead of the hitch you have now as it will give you the additional clearance you need to allow you to use your really nice Kuat Piston ION # KU89SR without needing additional adapters or anything else. Now with that said you could use the Kuat Pivot V3 adapter part # KU38CR with your current hitch and bike rack and that would also give you...
