An electric vehicle comprises a drive belt mounted about a motor output and about a drive wheel. The drive belt is driven by an output torque and experiences the output torque in a first torque direction and in a second torque direction. A belt tensioner comprises a tension pulley in contact with the drive belt, and a tensioning mechanism configured to displace the tension pulley in a first direction against the drive belt to tension the drive belt upon the drive belt experiencing the output torque in the first torque direction. The tensioning mechanism is configured to allow tension in the drive belt to displace the tension pulley in a second direction opposite to the first direction upon the drive belt experiencing the output torque in the second torque direction.
