How do you calculate the gear ratio on a bike?

This ratio would be calculated as follows: divide the wheel radius by the crank length; this will yield a single radius ratio applicable to all of the gears of a given bike. The individual gear ratios are calculated as with gear inches, using this radius ratio instead of the wheel size.

How to calculate a bicycle gear ratio?

The most popular gear ratios are pretty close to a 55 inch, which just seems to feel best for most people. The number is derived from a simple formula: (chainring size / cog size) X wheel size . Another popular unit for measuring gearing is Roll Out in inches.

What do gear ratios mean in a bike?

Gear Ratios In simple terms, a gear ratio on a bike refers to how many times the back wheel will rotate for each full turn of the crank arms (pedals). If we have a chainring with 30 teeth and a sprocket with 30 teeth, there is no difference between the two; one full revolution of the pedals will result in one full revolution of the wheel.

What is the best gear ratio for BMX bike?

It has around 2.78/1 gear ratio. The lesser the ratio is, the better it will be for your bike. Smaller gears make it easy to pedal and move the bike forward. This as well, is a very good ratio for a BMX bike. The gear ratio is almost 2.73/1 which is a perfect ratio to consider.

How do you calculate the gear ratio on a bicycle?

Instructions. Calculate the basic gear ratio for every gear on the bicycle, setting the rear cog as 1 for every ratio. For example, if a low gear has 22 teeth on the front wheel and 30 teeth on the rear cog, divide 22 by 30 to get 0.73. That creates a ratio of 0.73:1, meaning that for one turn of the pedals,...

How to figure bicycle gear ratios?

How to calculate bicycle gear ratio? Simple, just divide your rear cog size from your front chainring size. If you know their numbers, just input them below and we'll calculate it automatically for you! Also take a look at our complete bicycle gear ratio chart below to see how your size compares to other gearing options.

How do you calculate bicycle gear inches?

Gear inches are basically the equivalent diameter of penny-farthing (direct drive) wheel. You can calculate it simply by taking the gear ratio (number of teeth on the front chainring / number of teeth on the rear sprocket) and multiplying it by your wheel diameter.

What is gear ratio in bicycle?

The ratio speaks to the way that the sprockets multiply the effort made with the chainring. Bicycle gears began with the introduction of the train drive, making the bicycle a lot more efficient. Historically, bikes were fixed gear, meaning one revolution of the pedals was equal to one revolution of the back wheel, for a 1:1 ratio.

A low gear is one that enables you to cycle slowly – e.g. uphill – while pedalling at an easy cadence. A high gear is one that enables you to cycle quickly – e.g. downhill – while pedalling at an easy cadence. The first pedal cycles had the cranks fixed to the front wheel. The distance travelled for each revolution of the cranks was solely determined by the size of the wheel. That’s why penny farthings arose. A bigger wheel went further, so was faster for a given cadence. Wh…

6 hours ago Oct 09, 2017 . The problem with gear ratio is that it calculates the number of rotations of the rear wheel for every rotation of the crank, but it ignores the diameter of the rear wheel. If a bike with 20" wheels and a bike with 29" wheels both have the same gear ratio, the 29" bike will travel 45% farther with each revolution of the crank.
