A fixed gear bike is a type of bicycle that has a single gear ratio. This means that the gears on the bike are locked in place, and you cannot change them. There are different types of fixed gear bikes, but all of them have one common feature: they require more practice to learn how to ride correctly.

Fixed Gear bikes can be ridden on tracks or roads, but they tend to be less maneuverable than other types of bicycles. Here is the fixed-gear bike size chart:

What is a Fixed Gear Bike?

A fixed gear bike is a bike with no freewheel. You Coast on a Fixed Gear Bike by back pedaling. The cog is attached to the rear wheel and there is a lock ring that keeps it from moving. The chain then runs from the cog, around the chainring, and then back to the cog. This effectively makes the cog and chainring one piece.

How to Measure a Fixed Gear Bike

To measure a fixed gear bike, you will need to know the length of the top tube, the length of the seat tube, and the distance between the bottom bracket and the rear axle. You can find this information in the bike’s geometry chart.

Once you have this information, you can use a simple formula to calculate the size of the bike. The formula is as follows:

Top Tube Length + Seat Tube Length – Distance between Rear Axle and Bottom Bracket = Fixed Gear Bike Size

For example, if a bike has a top tube length of 20 inches, a seat tube length of 18 inches, and a rear axle to bottom bracket distance of 12 inches, the size of the bike would be 20 + 18 – 12 = 26 inches.

How to Choose the Right Size Fixed Gear Bike

Choosing the right size bike is essential to having a comfortable and enjoyable ride. With a fixed gear bike, it is even more important to choose the right size, because you cannot coast or freewheel, so you will be pedaling the entire time. Use this chart to help you choose the right size fixed gear bike for your height.


After you have chosen the style of bike you want, you need to determine what size bike will fit you best. To do this, you need to take two measurements: your inseam (inner leg length) and your torso length. Once you have these measurements, consult a bike size chart to find the right size bike for your dimensions.

Remember that the measurement guidelines are just that — guidelines. If you fall between sizes, it’s often better to choose the larger size for a more comfortable ride. And, of course, you can always adjust the seat and handlebars on most bikes to get a custom fit.
