A foldable scooter comprising:
- a first frame component, wherein the first frame component comprises a steering column and a handlebar, wherein the steering column is integrated with an electric drive unit speed controller which is constructed and arranged to operatively control a removeable electric drive module;
- a second frame component, wherein the second frame component is rotatably attached to the first frame component so that the first frame component can fold onto the second frame component and wherein the second frame component includes a deck;
- a front wheel operatively connected to the first frame component;
- and
- a rear wheel operatively connected to the second frame component,
The foldable scooter of claim I further comprising a removable electric drive module, wherein the electric drive module comprises a battery, a motor, a motor controller, a pivot arm, a charger point, and a housing which surrounds at least a portion of the battery, the motor, the controller, the pivot arm, and the charger point, and wherein the electric drive module is attached to the foldable scooter and controlled by the electric drive unit speed controller.
A foldable scooter comprising:
- a frame, wherein the frame comprises a first frame component and a second frame component, wherein the first frame component is constructed and arranged to form a steering column and a handlebar and is operatively attached to a front hub of a front wheel and wherein the second frame component includes a deck portion and is operatively attached to a rear hub of a rear wheel;
- a knuckle joint located within the front hub which is operatively attached to the first frame component and the second frame component, and which is constructed and arranged so that rotation of the handlebar around a vertical axis controls the direction of the foldable scooter;
- and
- wherein the first frame component and the second frame component are constructed and arranged so that the first frame component can fold onto the second frame component.
An integrated hub comprising a rim, wherein the rim comprises a torsional element and includes a plurality of cutouts constructed and arranged to allow for radial flexibility, and wherein a soft resin is molded into the plurality of cutouts to limit the flexibility of the rim and to prevent overload and distortion of the rim.
