## How do you know what gear you are in

But in each gear, **if you divide RPM by car speed**, you get a constant. That constant is different for each gear. So if you are fast at doing math in your head, and have memorized the constants, then you could know what gear you are in. Another way is to listen to the engine sounds.

## How do you tell if your bike is 10 or 11 speed

**Multiply the front gear number by the rear gear number to get the number of speeds**. For example, if you have two front gears and five back gears, you have a 10-speed bike.

## How do I know what gear IM in on my bike

The first **number is the number of teeth on the smallest of** the 8 gears. The second number is the number of teeth on the largest of the 8 gears. The number is often engraved on the gear, so if you use that, just make sure you take the number from the largest gear.

## Which gears for which speed

Remember each car will be geared slightly differently, but a good rule of thumb for changing gears is that first gear is for speeds up to 10 mph, **second gear is for speeds up to 15 mph**, third gear is for speeds up to 35 mph, fourth gear is for speeds up to 55 mph, fifth gear is for speeds up to 65 mph, and sixth gear …

## How do you tell if your bike is a 11 speed

What size gears do I have? The only way to know what's on your bicycle is **by determining the number of teeth on the largest gear on your rear wheel**. This is typically shown on the cassette's packaging. For example, a road style 8 speed cassette might be marked as: 8 speed – 11-28t.

## Is my bike 11 speed

**Eleven speeds is only possible if you have one front sprocket and 11 rear sprockets**, although it is possible for a 12 speed bike to have two redundant gear ratios, actually it's quite common for a bike to have two or more redundant or nearly redundant ratios.

## What gear should I be in at 30mph

Third gear**Third gear** is a very flexible gear in modern cars, including diesel cars, and it's the ideal gear when you need to keep your speed to 30mph or under.

## What is the 3rd gear for

3 – Third gear

To be used when **you require more power but less speed and to prevent the transmission from shifting to a higher gear**. These gears may be used when going up or down hills and on road conditions like slush, loose gravel, snow, sand or ice, where you need more power but less speed.

## Is gear 1 high or low on a bike

**First gear is the lowest gear** and the easiest for climbing hills. Most multispeed bikes possess seven gears but may have up to nine. If your drive chain is on the smallest sprocket, which is the hardest gear, moving it to first gear causes the drive chain to climb up six spaces on the cassette if you have seven gears.

## What gears for what speed bike

Bikes generally have **1, 3, 18, 21, 24, or 27 speeds**. (10- and 15-speeds are obsolete and you don't see them on new bikes anymore.) Lower numbers are the low gears, and higher numbers are the high gears. First gear is a low gear.
