To the bike mobile.

While we typically prefer to ride our bikes to the trailhead or mouth of the canyon, such a practice can be prohibitively difficult if the trailhead or canyon happens to be several hundred miles away from home. In that case, the Thule Doubletrack 2 Bike Hitch Carrier with STL2 Lock provides enough flexible capacity to carry virtually any bike — from a skinny tire roadster to a snow-specific fat bike — to the start line. Since the Doubletrack 2 also adapts to different-sized hitches, you can turn virtually any vehicle with a hitch into a bike mobile.

Thule's Snug Tite 2 receiver lock system secures the rack to your vehicle, eliminating the ever-stressful rearview mirror wobble that will have you wanting to pull over every five minutes to confirm the rack's security. Locks for the bike mounts themselves add the same peace of mind during pit stops, and foldable center masts terminate in ratchetting hooks to keep the bikes steady during transit.

  • Fits bicycles with tire widths of up to 3in and wheel bases of up to 48in
  • Hitch adapter accommodates hitches of varying sizes
  • Wheel trays are adjustable for secure positioning
  • Center masts and locks secure each bike individually
  • May not accommodate small frames with low top tubes
  • Item #THU0301

Decent rack for the money

  • Familiarity: I've put it through the wringer

I shopped for months for a bike rack before finally settling on this Thule. I have a 2" receiver hitch on my '10 Forester and this rack fits perfectly. There is plenty of ground clearance for going up/down steep slopes without dragging. When the center mast is folded down I can open the rear hatch and there is enough room for my dog to jump in/out of the rear cargo area. When it is empty and folded up it sits fully below the rear window so I don't lose any visibility out the back. Super easy and quick to load and unload, and assembly only took about an hour.

My only minor annoyances with this rack are that it was missing hardware when it was delivered (which you have to order directly from Thule), and I'm not sold on its durability. It has been on my car for about 3 months now and one of the end plugs has fallen off and there are several spots that are rusting (and I live in a temperate climate). The center mast release also sticks, but this can be overcome with a little muscle.

Overall, it does its job well and I have zero concern about losing my bikes off the back of the car. There is minimal wiggle when driving down the freeway and it holds up well over bumpy dirt roads. The locks are an awesome feature. Just hope it holds up for more than a season.

Great rack for the money

  • Familiarity: I've put it through the wringer

This rack is a great hitch rack for the money. It is best used on 1.25" receivers, as it uses an adapter to fit the 2" receivers, which is not ideal in my opinion. It's not really a big issue just something worth considering.

It fits everything from road bike tires up to 2.5" mountain bike tires. I haven't been successful getting anything larger to fit. It fits my SB6 which has an exceptionally long 48" wheelbase, so most bikes should fit fine in this regard. Put the bike with the taller top tube on the outside of the rack, because the inner arm clamp sits below the outer clamp. If the taller bike is put on the inside then you may have issues getting the outside arm to cinch down far enough on the smaller top tube bike. This may sound confusing but it will make sense if you encounter it.

The locks are sweet, they lock the arms in place securely. It would take some serious work from a diligent thief to get around these locks so they are a great deterrent. The rack also locks to the hitch. I noticed the locks on the arms can be hard to reach, as certain types of bike frames may block them when the arms are tightened into place, but this is a minor detail.

The hitch pin tightens down removing most of the play/movement in the rack. It does still have a bit of play, but not much. We took it on a 3000 mile mountain bike road trip and it stayed secure the whole time, even in high wind conditions.

Installation is pretty easy, just make sure to tighten down all the bolts well. Overall this is a good rack for the price.

Thule Doubletrack

Great rack for the money. It is a bit of a pain that this doesn't have the tilt feature (but that's what an extra $150 gets you with the Transport rack). We've hauled our bikes on over 3000 mile trips with this, on off-road trails and the interstate, and it keeps everything locked down tight. Love that this one comes with a lock too.

Great Affordable Rack

  • Familiarity: I've used it several times

IM really liking this rack, about $150 less than top of the line, but does just about the same thing.. Comes with locks, easy to raise and lower for entry into rear of car. Stable on the road. great quality. Easy to load bike.


    my first trip my bike flew out of this thing going 70... havent figured out what went wrong maybe it was something i did not really sure.. good thing my bike was fine tho, my bike guy couldnt believe i didnt do any damage

    Great rack for the $$$$

    • Familiarity: I've put it through the wringer

    If you need a quality rack and don't want to sink 5 Ben's in it then this rack is great. No titlt option but the locking arms do fold down when not in use to access the tailgate of your SUV. I love the lock options on the securing arms for each bike. Not impenetrable but a nice deterrent. The hitch lock is also great for a would be thief who would just take the whole darn rack and bikes! So if your value conscience and want name brand look to this Thule model for sure.

    Great rack

      Straight forward installation. Includes all hardware so you don't have to go out and buy tools to install.

      Fits both bikes securely without much effort. I drive on open country roads at 70-80 mph. No problems

      Only complaint is their locking system. Does take some getting use too and at times it seams as if it will not lock but keep wiggling the key and it'll lock.

      Much more cost effective than a roof rack mount system if you were to start from no accessories on the car.

      Easy to use; stable enough

        One of our friends complains about some of the lateral movement of this rack. It does jiggle a bit, but the movement doesn't seem to put undo pressure on the frame or wheels. I'm a 125 lb woman, and while I didn't mount the rack on our Honda Fit, once my husband set the rack up, it's been very easy for me to use. (We debated a roof rack, and now I'm glad we didn't go that direction because it would have been difficult for me to use.)

        Overall, the rack seems well made and there's plenty of clearance off the ground to make it up and down our steep driveway. I'll write another review if I find something to complain about, but for now I love this rack, and at 20% off on, I love the price we paid!

        What is the advantage of the Transport T2 over the Doubletrack that justifies the $150 price difference? Is it mostly the ability to add the Transport T2 Bike Add-on?

        Hi. I have the Thule two bike carrier. The stem with the two hooks seemed really loose so I tightened them a bit. Now I can't seem to get the stem to lay flat so I can fold it up against trhe vehicle. Do the screws have to be really loose?
