What is the mass of a bicycle?

The mass of a bicycle can vary greatly depending on the type of bike and its components. On average, a standard adult bicycle weighs between 20 to 30 pounds (9 to 13.5 kilograms). However, this can vary depending on factors such as the size of the frame, the material it's made from (e.g. carbon fiber, aluminum, steel), and the type of components (e.g. gears, suspension, accessories) that are included.

Lightweight road bikes can weigh as little as 15 pounds (6.8 kilograms), while heavier mountain bikes with full suspension systems can weigh upwards of 40 pounds (18 kilograms) or more. Electric bikes can weigh even more due to the added weight of the battery and motor.

The mass of a bicycle is an important factor to consider when choosing a bike, as lighter bikes are generally easier to maneuver and accelerate, while heavier bikes may provide more stability and durability. Ultimately, the right mass for a bicycle depends on the rider's preferences and intended use of the bike.
