A mounting system for removably mounting a portable electronic device to an object comprises a base, a mount, and a locking component. The base includes a central aperture and connects to an object on which the portable electronic device will be mounted. The mount includes a coupler and a device connector for connecting to the portable electronic device. The coupler includes a shaft that may be at least partially received within the central aperture of the base. The locking component is integrated with the base and is shiftable between a locked mode in which it retains the coupler in the base and an unlocked mode in which it allows the coupler to be released from the base. The locking component includes a ring with a detent, a catch that engages the detent, and a lever which can shift the locking component between the locked mode and the unlocked mode.
