Size Matters
Bike size chart​
The tables below show the frame size that best suits your height. The deciding factor for the size of a bicycle is the frame – in particular, the seat post (the distance from the center of the bottom bracket to the top of the seat post). The sizes are measured in inches (MTB) or centimeters. You may find both units in the description of the bike.
