The Evo 1-touch tension system is a tension mechanism that is used on all Evo Powerboards' scooters It allows the user to adjust belt or chain tension with the use of only one hand and a phillips screwdriver or 13mm wrench.

Tension is increased by tightening a lever's bolt which pulls the lower shaft of the transmission away from the wheel. This action tightens the belt connecting the two. Reversing the process loosens the belt.
