Pardon the newb questions. I had a roof rack style bike rack (Yakima) when I had my Acura TL. Didn't really like it b/c I everytime I went biking I had to lift 2 bikes over head, take off the front wheel, and it took a long time to secure the front and rear to the frame. And even then, I was afraid the bikes were going to come off each time I drove.
This will be my first rear hatch rack, and I want to make a smart buy.
For the Northshore vertical shuttle rack:
1) How easy is it to put on and take off the rack from the hitch?
2) How easy is it to secure the bike to the hitch?
3) I checked Northshore's website. Is says their NSR 4 bike is not meant for road bikes. I have 1 mountain bike. My other bike (Specialized) has "skinny" tires. My daughter has larger "kids" bike, and my wife's bike is not a mountain bike. So does this mean the Northshore rack will not hold my other bike and wife's/daughter's?
North Shore and Recon racks exist to haul 4 or more, heavy (30-40 lb) down hill biased mountain bikes, frequently (say multiple shuttle runs on the same day, a few days a week) on bad roads. There is a niche of bikers for whom this is extremely important and will search out such capabilities, pay extra for it, and deal with 70lb+ racks. But it is overkill for most users. Both racks take advantage of a mountain bikes design in ways that are less than compatible with other bikes. North Shore's FAQ mentions problems with road bikes tire to fork crown distance while Recon 's FAQ mentions problems with thin tires. That doesn't mean you can't work around those issue for other bikes, but carrying non mountain bikes isn't the intent of the racks designers.
For your use case, I'd look at a tray type rack, that holds the bikes by the wheels rather than any sort of frame hold. Kuat, 1up and Thule all have models that do this. A full width tray really increases the flexibility and adaptability to different size and style bikes. The wheelbase of my road bikes is probably 3-4 inches less than my longer travel mountain bikes for example. So I'd avoid the carriers that look trayish but have fixed wheel baskets at both ends.
Personally I found the Kuat too complicated and I vaguely recall it not working as well with the 200 Series tail gate configuration as the Thule. I'd rarely use the work clamp feature, but it adds weight. But that was probably 8 years years ago and it was the companies first product revision that I tried. They are on a new design now and offer more basic carriers that might work better for me. I'd shop it against the Thule T2 as medium duty rack. Somewhere between the NSR/Recon and the different 1UPs.
The Thule T2 is heavy and largely bullet proof. I use mine 1-2x a week for 8 months a year to haul up to 4 heavy full suspension mountain bikes around. I've had it for 8 years now. (edit, I just remembered I bought right after trading in my '94 80 series for a 2010 LX) I usually run without the extra 2 bike extension. With the extension it does get long and I can see the advantages of the NSR/Recon approach.
For lighter duty the 1UP is a very decent option. It is well thought out. For one bike it is awesome. It can be taken on and off your car in minutes.
Even the 1.25" version was OK for light duty 2 bike use. I bought one to try out because the Thule is heavy and when I lived in an apartment it was really a pain to pull the Thule on and off and store. But I'd look at the 2" or another manufacture if you plan to take it off road or say travel across the country with one. I'd view 1UP as a very high quality carrier for casual use. It wouldn't be a mistake to buy.
For security, I loop a decently thick cable through the chain eyes on the hitch, through my bike frame and tires and use a large padlock. I've not seen a carrier built in security system I'd trust.
