Comments about Thule Big Mouth Upright Bike Mount:

To buy the full rack system and one of these bike carriers is about $500 - $600 or so. What Thule seems unable to mention are a few glaring issues:

-it seems very easy to steal a bike from this unit. They offer a lock option that attaches to the 'big mouth' portion of the unit, but as other have said, it seems really easy for a thief to just take the wheels off first and then they've got your bike. Also, it really doesn't look too hard to just unscrew most of the unit from the crossbars, and then take the whole thing away and worry about separating your bike from the big mouth later....

-if you buy Thule Aeroblades, you'll need the Thule XADAPT2 kit to connect the Big Mouth to it. Nowhere in the instructions, on the box, or on their website is this mentioned. I found this out from a third party website which had information on this. Worse still, the instructions for the XADAPT2 seems to think users only have VW cars or a truck bed rack. Not once is the word 'Aeroblade' mentioned. Also, the instructions are also poor because they don't show how to install half of the Big Mouth to the cross bars. Does Thule try to build these things themselves? The REI staff spent almost 30 minutes trying to figure this out on Thule's site before someone who had previous knowledge of this helped out....

Comments about Thule Big Mouth Upright Bike Mount:

I had heard that one of the drawbacks of the Big Mouth attachment was that it might scratch the bike frame where it clamped on. Thankfully, that has not been the case. The Big Mouth grips the frame solidly, but I have not seen any scratching of my bike frame. I'm very happy with the product.

Comments about Thule Big Mouth Upright Bike Mount:

The LOCKED frame jaws on this let my bike fly off the car at 60mph. Part of it is my fault for not using the tray wheel straps. $600.00 lesson learned I guess. Plus it's not very stable no matter how many times you tighten down the cams to your cross bar.When I went to put the broken bike back on the car there sat the jaws completely locked shut. I had to unlock it with my Thule key.

Can not lock to the roof rack itself. Can lock only the arm of the bike rack. Not fully thief protected.

Comments about Thule Big Mouth Upright Bike Mount:

on the 3rd season of use, we had a bike unlatch at the big mouth and tip over on the roof. LUCKILY, both wheel straps held on the tray and the bike tipped to the side hanging over the edge of the roof. still, it wasn't a reassuring experience on the side of the expressway and both of our big mouths were returned to REI.

Comments about Thule Big Mouth Upright Bike Mount:

Easy to use and great for quickly mounting and dismounting your bike. Unfortunately, it is just as quick and easy to steal your bike from it. After unclamping wheels, a would be thief would only have to turn your frame until it slips from the claws grips. I lost my bike this way. If you get this and intend on leaving you bike unattended, use a cable or chain lock through the frame and around your rack support bars. It will at least keep honest people, honest.

Comments about Thule Big Mouth Upright Bike Mount:

I used this rack for two different bikes. In doing this I have two different reviews for the Big Mouth.
The first bike is a Cannondale Furio X frame that has a tube that is the same circ the whole way down. It is a very large tube. The Big Mouth works great for this bike and is very secure.
The other bike I used with the Big Mouth is a GT i-drive 5. It has a tube that is skinny at the head tube and just gets skinnier as you get closer to the bottom bracket. My i-drive was on the roof on the highway and fell over to the side when the big mouth slipped off the bottom bracket and dented the roof of the car with bike pedals. Luckily the wheel straps were secure and held the bike on the car.
Regardless of the bike you use with the big mouth, the pull down handle that releases the clamp is kinda sketchy and the end caps dont stay on the tray. I have switched to the peleton and feel my bike is secure and locked down.

Comments about Thule Big Mouth Upright Bike Mount:

I bought a pair of Big Mouths about five years ago and have driven several thousand miles with them. Initial installation is easy, but takes a few minutes. Thereafter, getting them on and off the car is easy, but it is essential to make sure one mounts them on the cross rails exactly as intended, making sure the hooks are securely seated in the brackets - otherwise, they can jar loose on extremely bumpy roads (or off-road). One person can mount or dismount a bike fairly easily, keeping in mind that it is a rooftop rack and the bike must be lifted over one's head. Bikes are held quite securely. Unfortunately, a couple of weeks ago, I made the ultimate mistake of forgetting a bike was on the car and drove into my garage. So, how did it turn out? Fortunately,I was going dead slow. The mount's wheel straps snapped and the Big mouth clamp twisted but released the bike, which fell to the pavement. End result: $15 damage to the bike and $95 damage to the garage. The rack was pretty well chowdered up. All-in-all, a much better result than I dared hope for. Without hesitation, I am buying a new Big Mouth rack as a replacement.
