What Is the Mass of a Bicycle? Several Facts You Might Not Know

Written by Gary Johnson / Fact checked by Henry Speciale

what is the mass of a bicycle

It’s not uncommon to hear about how much a bike weighs and how it can affect the riding experience. When talking about what is the mass of a bicycle, we generally relate it to the overall weight of the equipment while in motion.

The best estimate for the mass of a bicycle is computing both the weight of the rider and the bicycle. These are two major factors that contribute to the mass of the bicycle and can affect the speed of your ride. If an average cyclist weighing 73kg rode on a 4.5kg bike, the total mass would be 77.5kg.

This article will explain what the mass of a bicycle really means. This will help you understand why some bikers with heavy weight consider getting the lightest bike while others prefer heavier bikes.

Why Does the Mass of a Bicycle Matter?

The mass of a bike matters in cycling because it directly affects your riding speed. In mechanical terms, the mass of a bicycle correlates with the amount of resistance your bike puts relative to acceleration.

Even when you are getting the mass of a bicycle in grams or the mass of a bicycle in kilograms, the total mass has a direct impact on your speed or acceleration.

The more mass the rider and bicycle has, the more energy or force it takes to get it moving. The ability of both the cyclist and bike to climb uphill lessens if the combined weight is larger than the average, and vice versa.

To put it simply, the more weight you add to a bicycle and its components, the more resistance there is in acceleration. The overall weight will significantly slow down the rate of acceleration when riding. If you reduce very little weight, it will hardly affect the speed of your cycling.

Bicycle Mass Rules


Lighter bikes speed up acceleration

The lightest bicycle in the market weighs 9.7 pounds. If you are climbing uphill and want to speed up your acceleration, you should use a bike with the lightest weight. This way, aside from the rider’s weight, there is no extra amount of weight that can slow down the cycling speed.

Heavier bikes drag down acceleration

It is a given that any additional weight you put while riding can directly slow down your climbing speed. It requires more energy to move a heavier bike up a hill. Further, the weight of the rider and the bicycle impacts the rolling resistance to tires. Your bike tires will carry all the weight. The rolling resistance increases when the weight of both the rider and the bike level up as well.


Speed and acceleration are highly dependent on the weight of both the rider and the bicycle. If you want to accelerate faster and increase speed, we recommend choosing lighter bikes and reducing your body weight. The key to improved acceleration and speed is balancing your weight and the bicycle.
