The ridable vehicle of claim 2, wherein: the electric motor is a variable speed electric motor; andthe power delivered to the variable speed electric motor is controlled by an acceleration member. 5. The ridable vehicle of claim 4, further comprising a seat mounted to the chassis and positioned in front of or above the battery housing. 6. The ridable vehicle of claim 5, wherein the seat is supported by the chassis so that the steering assembly and the acceleration member are within reach of a driver seated in the seat and so that the driver is seated low to the ground. 7. A ridable vehicle, comprising: a hollow tube chassis to which a steering column is coupled, where the steering column includes a steering axis;a fork supported by the steering column and rotatable about the steering axis;at least one front steerable wheel supported by the fork and configured to be driven by an electric motor, the electric motor being at least partially supported by the fork;a battery housing supported by the chassis, where the battery housing contains a controller and at least one battery;wiring configured to provide power from the at least one battery to the electric motor;an acceleration member that controls the power delivered by the at least one battery to the electric motor;two caster wheels supported by the chassis, where each caster wheel is configured to rotate around a rotational axis and swivel around a swivel axis;a seat supported by the chassis so that a steering assembly supported by the steering column and the acceleration member are within reach of a driver seated in the seat, the seat having a low seating surface configured to contact and vertically support a driver, the low seating surface being arranged at a position level with or lower than the electric motor so that the driver is seated low to the ground. 8. The ridable vehicle of claim 7, wherein the fork comprises two vertical supports and the electric motor is positioned between the two vertical supports. 9. The ridable vehicle of claim 7, wherein the at least one front steerable wheel rotates about a wheel axis, and the electric motor is positioned above the wheel axis. 10. The ridable vehicle of claim 7, wherein the fork is a zero camber zero rake fork. 11. A ridable vehicle, comprising: a frame including a steering column;a fork rotatably supported by the steering column;a steering portion coupled to the fork and configured to allow a user to rotate the fork;a front wheel supported by the fork and operably coupled to the steering portion so that a user can steer the front wheel by moving the steering portion, the front wheel being rotatable about a wheel axis;an electric motor being arranged to drive the front wheel, the electric motor being positioned above the wheel axis and being operably coupled to the front wheel by a drivetrain;a battery assembly supported by the frame, the battery assembly comprising a controller and a battery;a pair of caster wheels supported by the frame and each configured to rotate about a swivel axis, the caster wheels being positioned with their swivel axes at an angle relative to the frame, the caster wheels being fixedly supported so that the angle of the swivel axes relative to the frame does not change. 12. The ridable vehicle of claim 11, wherein the fork and steering column are inclined relative to the riding surface of the vehicle. 13. The ridable vehicle of claim 11, wherein the fork is a zero camber zero rake fork. 14. The ridable vehicle of claim 11, wherein each caster wheel is configured to rotate 360 degrees around its rotational axis. 15. The ridable vehicle of claim 11, wherein the electric motor is a variable speed electric motor, and the power delivered to the variable speed electric motor is controlled by an acceleration member. 16. The ridable vehicle of claim 15, further comprising a seat supported by the frame so that the steering assembly and the acceleration member are within reach of a driver seated in the seat and so that the driver is seated low to the ground. 17. The ridable vehicle of claim 11, wherein the fork includes two supports and the electric motor is supported by the fork between the two supports.
