They do not have to be attached to the frame but yes you do need them. When you buy a gyro kit for a bike it comes with a plate that has tabs on it. Unless it is an integrated frame, meaning the headset is two cartrige bearings down inside the frame, if so a gyro will not work without the tabs mounted to the frame. Hope it helped. :)
Depends on the gyro and the frame. Some gyros are meant to work with tabs welded onto the headtube of the frame, some have the tabs as part of the press-fit headset cups. You can't put a gyro for welded tabs on a bike that hasn't got them.
No. The Verde Theory is a BMX bike for riding on a track. A Gyro would only come on a Freestyle bike made for trick riding.
Depends on what you want from your bike. A MTB is likely to have better riding characteristics than a freestyle bike, important if you want to cover any distances with your bike. But if you only want to ride at skate parks, then a freestyle bike is probably the better choice.
BMX race bikes often have only one brake, at the rear. And for a race bike, there's no need to be able to spin the handlebar - so no gyro. But of course, you could have one installed - if you wish. Or you could set a bike up with only a front brake. In which case you don't need a gyro either - you just run the brake through the steerer tube.
If you spin your bars the brake wires will get all tangled up.
yes
check for any obstructions on the frame if there is anything get it off
I don't believe so. My son bought a 2011 verde eon & it is not equipped with the tabs to mount a detangler. Not positive about the 2010.
You could get tabs if you are using I.E.7, Firefox, and any other browsers that supports tabs. You might be able to get tabs in add-ons.
To be honest if you have to ask then I would take it to your bike shop. Unless its a high end gyro with the London mod (€200+) then I would personally run a long linear cable.

Some benefits of having jump bikes are that jump bikes are more capable of navigating through rougher mountain terrain, and being able to add several additions to one's bike like a pro hydraulic gyro.
