3-In-1 Bike Rack

The Pro Series Q-Slot is a triple threat when it comes to carrying your bikes. This platform-style, hitch-mounted rack is 3 bike racks in 1 tidy package. The base rack can be used as a 2-bike carrier for 2" hitches or - with the included add-on installed - as a 4-bike carrier for 2" hitches. The add-on can also be used as a stand-alone 2-bike rack for 1-1/4" hitches, making this rack perfect for people with 2 cars that have different hitch sizes.


Multiple Configurations

You can use either of the 2-bike carriers the old-fashioned way - just slide it into your 1-1/4" or 2" hitch and secure it with the appropriate anti-rattle hitch pin. For full 4-bike carrying capacity, slide the shank of the 1-1/4" rack into the front of the 2" rack and secure it with the 1/2" pin.


Easy Bike Loading

The Q-Slot is super easy to load, even when used in the 4-bike configuration. The rack has 2 upright masts with frame hooks that adjust independently of one another to hold 4 bikes of different - or identical - styles and sizes, and they eliminate bike-to-bike contact during travel. The upright masts can be folded down by releasing bail pins at the bases, allowing you to load bikes onto the rack without interference. Folding the masts down also provides easier access to your vehicle's rear cargo area.


Cushioned Frame Hooks

Once your bikes are in place on the rack, simply slide the cushioned hooks down snugly over the bike frames and tighten the hand knobs. These hooks are staggered and operate independently of each other so that you can carry bikes of different sizes, and they are padded so that they won't scratch or scuff the paint finish on your bikes.


Adjustable Wheel Hoops

The versatile rack has adjustable wheel hoops that enable you to carry bikes of different lengths as well. These wheel hoops adjust with hand knobs and slide along the bike rack frame to accommodate your specific bike lengths. The hoops include straps with hook-and-loop closures (similar to Velcro) to secure your bike wheels in place.


Excellent Ground Clearance

The rack features a unique dual rise shank (the base rack and add-on rack both have a rise) for ultimate ground clearance. These rise shanks provide great clearance when the racks are used independently and superior clearance when the racks are used together in the 4-bike configuration.


Convenient Storage

The horizontal bars can be folded up for storage when the bike rack is not in use. Simply pull the bail pins at the base, fold the arms up, and re-insert the pins.

Video Transcript for Pro Series Q-Slot 2 and 4 Bike Hitch Bike Rack Review

Today, we'll be reviewing the Pro Series Q-Slot Platform bike rack, part #PS63138. This is a hitch-mounted bike rack that can carry 2-4 bikes with 2 inch hitches when needed with an add-on rack. The add-on rack can be used separately for 1 inch and 1/4 inch hitches. The Q-slot has cushioned hooks that slide up and down independently on the masts. This helps hold bikes of different shapes and sizes in place. There's also some padding on the hooks which protects the bike's frame from scratches. There's wheel-mounts with straps that slide back and forth, which will adjust for varying bike lengths and secure the wheels in place. The masts pull down for bike loading or to access your rear cargo area. The wheel-mount arm folds up, as well, for storage after a trip. The shank of this bike rack has a dual rise, which provides more ground clearance and has an anti-rattle bolt. It has rear reflectors, which help with making the q-slot more visible at night, and it has a black powder-coat finish to make it rust resistant. Now that we've gone over some features of the q-slot, let's show you how it's installed. We'll start in its 4-bike configuration, and slide the rack into the hitch of our vehicle. Remember, the 4-bike configuration is only for 2 inch hitches. We'll line up our pin holes, then we'll install our anti-rattle bolt with the washer. Now, we'll take the provided wrench and tighten it down and place the clip on the other side. With that done, we'll pull these pins here, which will release the wheel-mount arms down. We'll repeat this for all arms. Next, we'll show you how to pull down the masts of the q-slot.

We'll remove this pin at the base and gently let them tip away from the vehicle. As you can see, we now have full access to the cargo area. As mentioned earlier, the q-slot has cushioned hooks, which hold down your bikes. To adjust them, we'll loosen these knobs, which will allow the hooks to move freely. The wheel mounts also have these knobs that, when loosened, will allow them to adjust. The wheel mounts also have this hook and loop strap which wraps around the wheel and keeps it in place during travel. With all of our arms folded out, we're ready to place our bikes on them. We'll place our first bike on the q-slot, first adjusting the wheel mounts into position. Next, we'll place our hooks into position on the frame. Now, we'll move back down to the wheel, take our hook and loop straps and secure the wheels. We'll repeat this process with the rest of our bikes. Now, we'll show you how to make our 4 bike rack into the two separate bike racks.

We'll loosen up the anti-rattle bolt and pull the inch and 1/4 shank out, and place that into our other vehicle's hitch. Next we'll repeat the installation steps to load a bike on it. That will do it for the review of the Pro-Series bike rack, part #PS63138. .

We love this bike rack! It was easy to put together and very easy to use! We really like the option to carry 2 bikes or 4. We would highly recommend this product! 99070


Comments

Is there anyway you can lock the rack to the 2 receiver instead of using just the provided cotter pin?

comment by: Armando - 1/12/2014

I called up my contact at ProSeries and he confirmed they do not offer a locking version of the anti-rattle bolt or have a way to lock it. It is possible that there are padlocks out there with a small enough shackle to fit in the cotter pin hole, but we do not have any that small.

Comments

Oh wow. Excellent question Armando. So it would be pretty easy for someone to just remove the cotter pin and walk away with the rack?

comment by: John - 4/7/2014

The potential thieft would need a wrench as well. A threaded bolt is used to snug the rack in the hitch and the cotter pin is used make sure the bolt could not back all the way out. ProSeries does not have a locking option for this rack. For a similar rack that will lock, check part # HR1400 from Hollywood Racks or part # SR2902LR from SportRack.

  • Trailer Hitch Mount Bike Rack for 2 or 4 Bikes on a 2012 GMC Acadia
  • For your needs the Pro Series Q-Slot bike rack # PS63138 would be a great choice. It can be a 2-bike or 4-Bike rack when you need it. The adjustable wheel loops and padded hooks are compatible with all types of bikes. Step through frames, if low enough, can sometimes elude the center hook. If that is the case an adapter bar like you are describing can be used. This rack fits all the things you are looking for, including price, making it a great option for you. The rack does fold up but does n

  • Hitch Mount Bike Rack Recommendation for a 2011 Trek 7300 with a Low Step-Through Bar
  • In my research I found that the Trek 7300 has a height measurement of 17.64 inches above the ground where your step through bar is located. When using a rack such as the Pro Series # PS63138, that step through area is also the attachment point to hold the bike in the rack. My technical contact at Pro Series let me know that the attachment bar on the rack you referenced moves all the way down the bar so it will go low enough to attach to your bike. With this rack you also have wheel straps and

  • Will a Bacchetta Giro 20 Recumbent Bike Fit the Pro Series Q-Slot Trailer Hitch Mount Bike Rack
  • The 47 inch wheelbase will not be a problem on your recumbent bike but that large seat could cause some issues. The hook on the Pro Series bike rack # PS63138 would have to come down right where the seat is if the bike is centered on the rack. You would have to carry the bike slightly off center for it to work. This could cause the bike to stick out too far on one side on narrow vehicles but probably would not be too bad on your Escape. I have included a link to a video review of this rack fo

  • Will Bikes With 16 Inch Or 18 Inch Wheels Fit On A Pro Series Hitch Bike Rack PS63138
  • I measured both of the wheel cradles on the Pro Series Q-Slot Platform-Style 2 Bike and 4 Bike Carrier, part # PS63138. The cradle measures 15-1/4 inches from the bar to the inside edge of the cradle, Based on that measurement, the bikes with 16 inch and 18 inch wheels should fit just fine. I have linked you to a product review video for this carrier. I have attached a couple of photos that show a bike with 16 inch wheels on the rack. With the adjustable cradles you can see that the cradles a

  • How Much Does the 2 Bike Rack of the Pro Series Q-Slot 4 Bike Rack Weigh
  • Just the 2 bike portion of the Pro Series Q-Slot Platform-Style 2 Bike and 4 Bike Carrier # PS63138 weighs 34 lbs. If all you needed was the 2 bike version of this rack you would want part # PS63134. The full 4 bike rack weighs 66 lbs.

  • Will a Baccetta Giro 20 Recumbent Bike Fit on Pro Series Q-Slot Trailer Hitch Mount Bike Rack
  • The wheelbase on the Baccetta Giro is fairly short since the pedals are out in front of the the handlebars (about 47 inches). The main issue is going to be the large seat. However, you can position the bike on a bike rack like # PS63138 that you have referenced in such a way to where the bike is more to the left or right and the center hook can come down on the frame to secure the bike. This is a 2 or 4-bike platform rack that fits 2 inch trailer hitch receivers only. If you can tell me the h

  • Replacement Anti-Rattle Hitch Bolts for the Pro Series Q-Slot Platform-Style Bike Rack # PS63138
  • I have some options that will work for you, however, Pro Series does not offer replacements anti-rattle bolts for their bike racks. Instead, you can use the Softride Replacement Anti-Rattle Hitch Bolt, # SR22967, for the 2 inch shank and part # SR19696, for the 1-1/4 inch shank. These hitch bolts will look different from the original hitch bolts, but they will work with the Q-Slot Platform-Style bike rack. I had the Q-Slot bike rack and the Softride replacement hitch bolts, so I made a short

  • Can Bikes Be Locked to Pro Series Q-Slot Platform-Style Trailer Hitch Mount Bike Rack
  • In order to lock the bikes and rack to the trailer hitch when using the Pro Series Q Slot bike rack # PS63138, you will need to use a cable lock. The rack itself does not have the ability to lock the bikes to the rack. For a cable lock you can use # CAB-10.

  • 2 Bike, Platform Bike Recommendation with Threaded Locking Hitch Pin
  • The diameter of the hitch pin included with the Pro Series Q-Slot Platform Bike Rack # PS63138 is 5/8 of an inch. However, this rack has a threaded hitch pin so an unthreaded locking hitch pin would not work. I think your best option would be to get a Hollywood Racks Sport Rider part # HR1400, this is a very similar rack that comes with an anti-rattle bolt that locks. Check out the review video I attached for this rack for you to check out also.

  • Bike Carrier Recommendations For 2005 Toyota Solara Convertible
  • For your 2005 Toyota Solara, the hitches we offer are Class ll hitches with 1-1/4 inch receiver openings. This does limit you when you choose carriers that would work for you. Using an adapter to reduce the 2 inch bike carrier shank to fit in a 1-1/4 inch receiver reduces the tongue weight and towing capacity of the hitch by 50 percent. The carrier I recommend that will fit your hitch is the Swagman XTC-2 Platform Bike Carrier, part # S64670. This is a 2 bike carrier and has a weight capacity of

  • Will the Pro Series Q-Slot Trailer Hitch Mount Bike Rack Clear the Spare Tire on a 2008 Toyota RAV4
  • The Pro Series Q-Slot just might be a fit for your 2008 Toyota RAV4. You will need to take an important measurement first. You will also need to have a 2 inch trailer hitch for the rack to fit. Measure from the center of the 2 inch trailer hitch pin hole straight back to the distance required to clear the rear of the vehicle. If that measurement is less than 12 inches then the rack will fit. I have included a link to our help article that shows how to take the measurement. I have also incl

  • Availability of Hitch-Mount Multi-Bike Rack That Does Not Make Contact with Bike Frame
  • Your 2006 Dodge Grand Caravan with Stow-N-Go seats can be equipped with either a 1-1/4-inch Class II hitch or a 2-inch Class III hitch. All 2-inch hitch-mount bike carriers, including the Pro Series Q-Slot Platform-Style rack # PS63138 that you referenced, fall into one of two general types, either hanging style or platform style, and to some degree both types will make frame contact. Hanging style racks suspend the bike from one or two arms on which the main top frame tube rests. Platform s
