Basically, speed.

Schmover

At 3rd level, your ki allows you to schmove, granting the following benefits:

• Whenever you make an attack roll on your turn, you can expend a ki point to increase your movement speed by half of what it typically is.
• You gain a climb speed equal to your walking speed.
• If you take a Dash action or Step of the Wind, your movement cannot be impeded by nonmagical or magical means e.g difficult terrain.
• If you take Step of the Wind to Dash, do not expend a ki point.

Momentum

At 6th level, you can impact schmove into other people. When you make an attack roll after moving 30 feet or more that turn, you deal additional damage equal to half the movement taken.
At 17th level, the damage increases to equal to the movement taken.
