A two-wheel scooter comprising:
- a body comprising a deck, a front end, a rear end, and a longitudinal axis, the deck configured to support a user;
- a steering assembly connected to the front end of the body, the steering assembly comprising a handlebar, a steering shaft, and a front wheel;
- a rear wheel connected to the rear end of the body;
- a rear drive assembly configured to drive the rear wheel, the rear drive assembly comprising an electric motor and a transmission;
- a battery housing under the deck, the battery housing comprising an aperture;
- and
- a battery in the battery housing, the battery configured to provide electric power to the electric motor, the battery selectively removable from the battery housing through the aperture along a direction that is generally parallel with the longitudinal axis of the body, wherein when the battery is in the battery housing a front end of the battery protrudes longitudinally frontward from the front end of the body, thereby providing a grasping portion to aid removal of the battery.

A method of replacing a spent battery in an electric scooter, the method comprising:
- disengaging a lock of a folding assembly of the scooter;
- folding the scooter, wherein folding the scooter comprises:
- pivoting in a first rotational direction the steering assembly of the scooter relative to a body of the scooter;
- and
- activating, with the steering assembly, a brake of the scooter against a rear wheel of the scooter;
- withdrawing the spent battery from the body in a first linear direction generally parallel to a longitudinal axis of the body;
- inserting a fresh battery into the body in a second linear direction generally parallel to the longitudinal axis;
- unfolding the scooter, wherein unfolding the scooter comprises pivoting in a second rotational direction the steering assembly relative to the body;
- and
- engaging the lock of the folding assembly.

A two-wheel scooter comprising:
- a body comprising a deck, a front end, a rear end, and a longitudinal axis, the deck configured to support a user;
- a steering assembly connected to the front end of the body, the steering assembly comprising a handlebar, a steering shaft, and a front wheel;
- a rear wheel connected to the rear end of the body;
- a rear drive assembly configured to drive the rear wheel, the rear drive assembly comprising an electric motor and a transmission;
- a battery configured to provide electric power to the electric motor;
- a brake configured to move into contact with the rear wheel;
- and
- a folding assembly configured to enable the steering assembly to pivot relative to the body between an unfolded state and a folded state, wherein in the folded state the steering assembly contacts the brake, thereby inhibiting rotation of the rear wheel.

- and
- a folding assembly that connects the steering assembly and the body, the folding assembly comprising a hinge and a lock, the folding assembly configured to enable the steering assembly to pivot relative to the body between an unfolded state and a folded state, wherein:
- in the unfolded state and with the front and rear wheels on a riding surface, the steering assembly blocks removal of the battery from the battery housing and the battery is directly below the folding assembly;
- and
- in the folded state, the steering assembly does not block removal of the battery from the battery housing.
