The disclosure relates to improved friction drive systems, control algorithms for friction drive systems, and automatic traction control for friction drive systems. Embodiments of friction drive systems and methods may improve control over an amount of normal force between a contact surface on a friction drive (e.g., disposed on a drive motor) and a tire or wheel of a wheeled vehicle. Embodiments of friction drive systems and methods may dynamically adjust the normal force between the contact surface and the tire or wheel in response to rapidly changing conditions, such as weather, road surface, and/or tire inflation. Embodiments of an automatic traction control system may adjust the normal force to avoid slippage while minimizing tire wear and maximizing battery efficiency. Embodiments of friction drive systems and methods may allow a user to calibrate or adjust the amount of normal force delivered based on their preferences or based on a selected mode of operation.
