Thule BSTK2 Bike Stacker , Black

Very stable & sturdy - holds my two mountain bikes in a minimal amount of space. Easy to assemble, place and move. Adjustable arms work well. Only note - I used some heavy plastic sheet, like the kind that many christmas ornaments or (in my case) OXO coasters come in, cut to strips to avoid scarring the metal finish with the lock down screws in the arms. Overall an excellent rack at a good price.

I had two Allen racks that screw into the wall for my road bikes. We moved and I did not want to drill holes in the garage walls to mount the racks so I found the Thule Bike Stacker. It went together quickly and is very stable. The road bikes set close to the wall and stack easily. This is the best rack that I have found anywhere to safely store nice road bikes.

We got these to hold our 2013 Specialized Myka 29er and 2014 Specialized Hardrock Sport Disc 29er. It fit both bikes without a lot of hassle. We would recommend having a friend help with the initial adjustments and such, since the arms can be difficult to adjust for the first time while holding the bike(s) in the air. Once set up, it is SUPER solid and doesn't move at all. One of our bikes is almost at the very top of the Stacker, and it has almost no movement back and forth or side to side. We put this in the dining room of our apartment (since we don't have a garage) on carpet, and it is still super stable and solid. It comes in a pretty small box, which makes you think it isn't that strong, but it is actually super strong. Again, get someone to help you get the holder arms adjusted the first time. Definitely going to be buying more Thule products in the future!

I bought this bike rack to keep our bikes organized and out of the way and in this role the bike rack performs well. The frame is well designed and is sturdy on a carpeted floor. The arms are easily adjusted and seem to hold securely. You will need a wrench to tighten the bolts when assembling the frame as tools are not included in the box. The Bike Stacker is easy to assemble and took me about 10 minutes to complete. Some of the other reviews mention rust being an issue if this bike holder is kept in a humid environment and I agree that this could be an issue. The paint on the frame doesn't seem very durable as there were several chips with exposed metal that could be a problem if the unit were kept outdoors. Overall, I am happy with the purchase.

I just received and set up my rack. After reading all the reviews I was sold, easy to assemble, durable, adjustable, well constructed and engineered . . . what more could you ask for right? How about steel tubing that doesn't distort and collapse when you hand tighten the support arms. Please keep in mind that I am a small woman (120 #'s soaking wet) and not a physically strong person by any definition of the word. Also when tightening the knob to secure the support arm it has a strong tendency to twist out and away from the rack towards the removal position versus in tighter toward the center. Had it been tapped and used a reversed style thread pattern from traditional would have made more sense. I really expected better from Thule than this, I have their "Swing-Daddy" hitch rack and love it. This one is most likely going back in the box and getting returned so I can get something more durable and better engineered.

Generally I like Thule products, but I almost regret buying this one.Seems vertical bike storage options are hard to come by, so I heedlessly bought this one based on brand reputation, although I was wincing at the price and doubtful given the lack of product photos. I should have read more reviews!I see now that several people pointed out some of the poor design choices. I too can vouch for them, with some observations of my own:1. Storage arms are "secured" with a metal bolt that screws directly onto the painted frame which cannot help being marred (see photo). As someone suggested, 1-2" spaced threaded holes should have been used, like the legs of a work bench. For $200, it is shameful that this was not done.2. Upper frame is not attached to lower (also shown in photo). It simply slides on, and the middle cross-bar that is so obvious to grab for lifting will pull the frame apart. This is a practical joke design. Not my kind of humor.3. Assembly is straight forward, but the initial marriage of the lower frame, lower cross-bar, and legs is a pain. All need to be put together at once as you screw the bolt through the leg, frame, and into the threaded cross-bar. Not an easy one person job if you are lacking a vise, clamps, or some other means to hold the pieces together.In the end, the bikes are stacked as advertised. But for the price Thule should have done better. If it were easier to re-box and return I probably would. Still might, but I will give it a week.

Repeat purchase of this product for my 2 Bianchi and 2 Specialized bikes.If you are an avid cyclist, you will know the weight of high end C2C & B4P Bianchi bikes, so the bikestacker is plenty strong. However, with high end or any bikes, you don't want the rack damaging the finish. No problem. There are attachable 'cups' which holds the frames in place.Specialized bikes are little heavier; 'CruX' comp & Stumpjumper, but the Thule stacker is plenty strong to hold them. Frame of the Stumpjumper is odd shaped geometry, but the arms of the bikestacker can be manipulated to fit the frame.I have a 3rd Bianchi which sits on a trainer in front of the bikes. Mentioning this, because the 'cups' are flexible enough to pull bike on the bottom of the rack easily forwards or backwards, to condense space.Bikes hang off the floor, in my bedroom, for easy vacuuming. Racks move easily anyhow, regardless of weight of the cycles.Prior to this 2nd purchase, I had a different brand rack, which didn't last long.
