There are two ways to adjust the seat height on Dott bikes, depending on the type of bike you’re riding.
Most bikes have a yellow lever underneath the seat: While pressing the yellow lever, push the seat down or pull the seat up to your desired height. The seat will lock into place as soon as you let go of the yellow lever.
For bikes with a clamp underneath the seat: Pull the clamp open, then push the seat down or pull the seat up to your desired height. Push the clamp closed again to lock the seat into place.
