What size wheel is 700x25c?
700x25c indicates a tire with a 700mm outer diameter and a 25mm width. A third type of tire size might appear on either a mountain or a road tire: 25-622 is the International Standardization Organization (ISO) way of identifying the 700x25c tire in the example above.
When you fit a speedometer to your bicycle you have to tell the computer the circumference of the wheels Why is this necessary?
You dial in the circumference of your wheel. The circumference is the distance rolled out by one revolution of the wheel. The speedo counts the number of revolutions the wheel makes each time the magnet on the spoke closes the electrical switch – the sensor. This allows a current to flow for a short while.

How do I measure my bike speed?
Count and Multiply You can have anywhere from one to 10 on here. 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. If you have one front gear and three back gears, you have a 3-speed bike.
Will a 700c TYRE fit a 28 inch?
The tyres can differ, but the 28”, 700C and 29er are all the exact same rim diameter. The 700 markings will be followed by the width in mm, and the 28 or 29 markings will be followed by the width in inches.
How do you determine the wheel size of a bicycle?
The International Organization for Standardization (ISO) measuring system uses millimeters to signify the size of your bicycle’s wheel. If you don’t have a measuring tape with metric rules, just be aware that there are 25.4 millimeters in one inch and determine the width with a calculator, multiplying inches x 25.4.
What is the standard size of a bicycle wheel?
Bicycle wheels come in many different sizes. The standards range from tiny 12 inch diameter wheels up to massive 29 inch diameter wheels. When it comes to an electric bicycle though, you’ll likely have one of three options: 16, 20 or 26 inch.
What is the diameter of a bicycle wheel?
With the exception of BMX models, most adult bicycle wheels are between 26 and 29 inches in diameter. If your tire is mounted, check the sidewall to find the measurement. Measure the flat part of the tire across the tread from one side to the other. The distance is the tire’s width. It can vary greatly depending on the tire’s intended use.
How do you calculate tire size?
You can use our tire size calculator to find the tire size, or you can use a few formulas. sidewall = section width × (60 ÷ 100) diameter = (sidewall × 2) + rim diameter. Thus, the wheel diameter is equal to the section width in inches times the aspect ratio divided by one hundred, times two, plus the rim diameter.
