Not all bikes have "gear". Straddle bikes and direct drive bikes - with cranks directly attached to a wheel axle - don't have gears.
Well, a track bike is a bike dedicated for use on a velodrome. It has a fixed gear, no brakes, often a steel drop bar and some other features. But with a but of determination you can stick a fixed gear rear wheel in any kind of bike. The wouldn't make it a track bike, but would make it a fixie. If you want to be hard core in your fixie riding, the "purest" is of course to ride a track bike in traffic too.
I have no idea what you mean by "gear bike", so the question can't be answered.
Top Gear Hyper Bike happened in 2000.

Yes
Your bike gear may be slipping due to a worn out or improperly adjusted gear cable, a worn out gear cassette or chain, or a misaligned derailleur. It is important to have your bike inspected and serviced by a professional bike mechanic to determine the exact cause of the issue.
A 2-gear bike offers the advantage of being able to switch between two different gear ratios, allowing for easier pedaling on different terrains or inclines. This can provide more efficiency and comfort while riding compared to a single gear bike, which has a fixed gear ratio.
no dirt bike gear is just a helmet and jacket, but paintball gear is a helmet a paintball gun and padding

Pick a gear that gives you the right ratio, then go for it. No difference than from a single-speed bike.
Should be regular 2 stroke oil
An automatic gear bike offers the advantage of easier and smoother gear shifting compared to a manual gear bike. This can make riding more convenient and less physically demanding, especially in stop-and-go traffic or on hilly terrain. Additionally, automatic gear bikes are generally easier for beginners to learn how to ride.
