Hard to tell what you mean here. There is a design which roughly fit the description of bike gear box - the NuVinci, and that one use a CVT(continuously variable transmission). For a CVT it's impossible to say WHICH gear you're in, apart from forward or reverse - as they are continuously variable.
Or maybe you're talking about a regular internally geared hub (IGH), in which case the gear used is the one selected.
Or maybe you're talking about motorbikes, which do have fairly solid gear boxes containing cogwheels with usually diagonal-cut drive wheels, and straight cut reverse gear.

What is the purpose of the front chain ring on a bicycle and how does it affect the gear ratio?
The front chain ring on a bicycle is used to transfer power from the pedals to the rear wheel through the chain. It affects the gear ratio by determining how many teeth are engaged with the chain, which in turn affects how much force is required to pedal and how fast the bike can go.
What is the average bike wheel size commonly used in the cycling industry?
The average bike wheel size commonly used in the cycling industry is 27.5 inches.
What is a worm and wheel gear?
it is used to change directions
What is a toothed wheel used to transmit energy?
Gear!
What simple machines are in a a bike?
A bike is compound machine.This means that it is made up of a bunch of different simple machines. Screws are used to hold the pieces together. The wheel of a bicycle is a wheel and axle. The pedals are also examples of this simple machine. The pedals are attached to a lever that turns a pulley. The gear shifts and brake handles are levers.
What is the purpose of a bike cassette spacer and how does it affect the performance of the bike?
A bike cassette spacer is used to adjust the spacing between the cogs on the rear wheel of a bike. This helps to ensure smooth shifting and proper alignment of the chain. The spacer can affect the performance of the bike by allowing for more precise gear changes and reducing the likelihood of the chain slipping or skipping.
What are the different types of brakes that can be used on a fixed gear bike?
The different types of brakes that can be used on a fixed gear bike are caliper brakes, cantilever brakes, and disc brakes. Caliper brakes are the most common type and are mounted on the frame or fork of the bike. Cantilever brakes are mounted on the frame or fork as well, but have a different design that allows for more clearance. Disc brakes are mounted on the wheel hub and provide strong stopping power.
How can I accurately measure the size of a bike wheel?
To accurately measure the size of a bike wheel, you can use a tape measure to determine the diameter of the wheel. Measure from the center of the wheel to the outer edge to get the diameter. This measurement is typically in inches or millimeters and is commonly used to indicate the size of a bike wheel.
What is a bike chain used for?
To transfer power from the pedals to where it can be used - the rear wheel.
What could a worm and wheel be used for?
gear box or speed reducer.
What is a second gear starter switch for on a 98 firebird?
since the car is rear wheel drive the 2nd gear start is used for when you are in snow or somewhere slick you turn that on and it will give you more power to get out. i had one never found it very useful
