RockyMounts GuideRail Hitch Mounted Bike Rack On Tacoma

2 Bike Tray System With Asymmetrical Loading To Prevent Contact

The Tacoma and Mountain Bike community go hand in hand. Between the reliability, capabilities and platform it allows us to reach remote locations while also giving us the ability to transport our gear.

While tailgate pads are an awesome option for those out there that don’t have anything covering their bed, the moment you start adding racks and shells it gets a little trickier. As for myself I ran into that dilemma after I picked up a camper shell and resorted to taking the front wheel off every time I wanted r. Finally got tired of doing that I decided it was time to add a bike rack to the fleet.

So I began the search and looked at all the options out there and settled on the new RockyMounts GuideRail.

RockyMounts has been around since 1993 in the great state of Colorado with the sole focus on building quality options for all disciplines. Their new GuideRail brings new and improved features that we’re going to take a look at.

Let’s get started!

Features & Specs

RockyMounts GuideRail Features & Specifications

This specific rack is for a 2″ receiver but can also be optioned in a 1.25″ hitch with an available shim adapter. The Tacoma comes standard with a 2″ hitch and helps with the rigidity and anti-wobble.

RockyMounts has mastered their anti-wobble system by coming out with a 3 axis system that has eliminated the wobble pretty much completely. It’s a little unsettling looking back and seeing your expensive bike wobble, luckily that’s not a worry with the GuideRail.

New RockyMounts Bike Rack

The rack has 3 notch positions to include, up (fully stowed), middle (bike transport), and down (opening tailgate). When stowed, it sits at 90 degrees up and when in the transport position sits level and when down sits at a 45 degree angle to the ground giving enough clearance to drop the tailgate.

RockyMounts GuideRail Unboxing

Included are the 4 tray pieces, the hitch mount, the hardware, and lock.

Installation Guide

Bike Rack Lock

We’re going to start by installing the hitch mount first. Locate the hitch pin and lock along with the provided tools.

Hitch Mounted Bike Rack Installation

Install the rack into the hitch and line up the holes to slide the pin through. Use a wrench to tighten down the bolt and install the lock on the other side. Tightening down the bolt will take out the slop and hold everything down.

The 4 Allen bolts and two mounting plates are what holds the trays to the hitch mount.

Assembling GuideRail Bike Rack

Slide in the trays with the blue levers facing outwards till they line up with the holes.

Using the plate, thread the bolt through the holes and tighten down with the provided Allen wrench till snug.

Your installation of the GuideRail is now complete! Super simple – which is what we love to see.

How To Use

How To Mount Bikes To RockyMounts GuideRail

Usage of the GuideRail is as easy as unlatching the blue levers till they’re facing outwards, now the upright wheel holds can move freely enough to get your bike on the tray.

Flipping the levers in so they’re parallel with the tray will engage the latching mechanism. Once it is set in the tray, flip the levers parallel and push the uprights till snug on the tire. It’s also really that simple to use… a common theme.

Built In Lock

One of my favorite features on the rack is the built in lock, that is by far the largest and most robust lock I’ve seen.

Thick chain link steel wrapped in fabric is a well designed lock, ensuring nobody is going to mess with your expensive bikes!

Now let’s move on to loading – which is super straight forward and painless. There are no straps or unnecessary secure points, rather the GuideRail uses two tire clamps to cinch down on the tires and hold it steady.

Step 1. Open Rack To Flat Position

Pull up in the blue handle in the center of the rack and pull down 90 degrees till it locks in place.

Step 2. Unlatch Blue Levers & Open Arms

Flip the blue levers outward to allow the ability to slide the upright tire supports all the way out. Depending on the length, you can adjust how far out the uprights go out to accommodate for a longer or shorter wheelbase.

Step 3. Lock Levers & Secure Bike

Flip the blue levers inward till they’re flat up against the rack, this will engage the locking mechanism. From there, place your bike on the tray (it doesn’t matter which way it goes), while holding the bike grab one of the upright supports and push forward up against the tire – repeat step on both wheels.

Once it is standing without your support, go back and push firmly on the upright supports until there is no slop. Give it the ole’ shake test to make sure it’s not going anywhere and repeat if you have another one!

Note: Make sure you alternate direction if putting two on.

Step 4. Bike Removal

Removal of the bike from the rack is super simple, a reverse of the above – except one key component to take special note of.

Instead of flipping the blue arm levers outward like when opening, you want to push in when releasing it from tray. This is because the arm is under load and if you pull back on the blue lever, over time it’ll break. Ask me how I know (rookie mistake). So when you have a bike in the tray, push forward on the blue level not back!

Pros & Cons

Bike Rack For Tacoma

I’ve been using this rack for a few months now (usually 2-4 times a week) and have been extremely pleased. Leaving it on my truck has made it convenient to throw the bikes on and within 15 seconds we’re ready to head out! The build quality stands out with it being able to withstand the daily abuse that it receives from living on a daily driver.

No real issues with it other than leaving it on my truck at all times has rendered the parking sensors useless and backup camera is mostly blocked when it’s stowed.


The whole setup is perfect. But some of my favorite features to mention are how easy it is to use, the quality, and the lock. I’ve had plenty of options both good and bad and they’ve always had their quirks that are an inconvenience, such as rubbing or wobbling. The GuideRail doesn’t experience those issues.

The tire clamps are easy to use and don’t make any contact and I haven’t had them come lose at all. Wobbling isn’t even a factor, it’s stout and when looking in the rearview mirror it doesn’t shake when taking large hits or driving offroad. The lock RockyMounts provide is very large and should help to deter thieves.


Not really anything to be honest… the only thing that is noteworthy is the price. At $850 dollars it’s a little steep but when you look at the quality you’re getting it’s understandable.

Final Thoughts

Long Term Review - RockyMounts GuideRail

To keep this short and sweet, I love this bike rack. It has been one of the best additions to my truck that I just leave on and forget about when I’m not using and ready to be used when needed. Between the features, build quality and ease of use I think it’s one of the best racks available at the moment.

Happy Trails!
