There's nothing wrong with the Novara bike you posted, but I think you should refrain from making any major purchases until you really know how you're going to use it. If you're relatively new to cyclist, I'll warn you- you will be buying another bike, and spending money on upgrades, accessories and a lot of stuff you didn't know existed a month ago, but now can't live without.
If you want to do long rides by yourself for fitness, and you haven't biked in a while, then you could do a lot worse than the Novara Express.
If you want to take part in larger group road rides, then I would suggest a more traditional road bike. Not that the Novara is in any way inferior, but speaking personally, I'm always a little intimidated by a pack of cyclists stronger than I am, so the more I can fit in, the better.
If you want to be more of a utility cyclist, running errands, commuting and the like, then I kind of like the Novara Buzz, but it lacks in essential accessories (mainly fenders, racks, lights and a lock)
Buy a bike that fits what you want to do, but accept that until you have experience, you won't be able to make an informed choice, and might get it wrong.
