A tricycle has a forward oriented fork member (20) supported for rotation about a steering axis (14) of the tricycle, a handle bar (50) mounted to the fork member, a cargo unit (24) supported by the fork member, and a pair of transversally spaced linkages (30), wherein each linkage at a proximal end is linked to the fork member and at a distal end supports a respective front wheel (16) of the tricycle. The cargo unit and the linkages are shiftable between respective forward and backward end positions to thereby transform the tricycle to a wheel cart and vice versa.

Presented are multi-axis pivoting coupler joints for motorized vehicles, methods for making/using such coupler joints, and electric scooters with multi-axis pivoting coupler joints enabling multimodal scooter operation. A pivoting coupler joint includes first and second bearing assemblies each with a respective housing, respective inner and outer races concentric with each other and located in their respective housing, and a respective set of rolling elements rollably interposed between their respective inner and outer races. The first inner race of the first bearing assembly receives therethrough and circumscribes an axle shaft of a vehicle wheel. The second inner race attaches to a wheeled rider deck of the vehicle. The first and second bearing housings are joined together and angularly offset from each other. For some applications, the first bearing assembly includes a pair of longitudinally spaced needle roller bearings, and the second bearing assembly includes a pair of longitudinally spaced tapered bearings.

A representative system includes a personal transportation device with: first and second wheels aligned along an axis; an idler wheel rearward of the axis; a platform configured to support a user in a standing position; electric motors to drive the first and second wheels; first and second hand grips fixed in position at respective locations forward of the platform; and first and second control actuators disposed, respectively, on the first and second hand grips, the first and second control actuators being operative to control rotations of the first and second wheels and configured to be actuated by corresponding thumbs of the user while hands of the user are grasping corresponding ones of the first hand grip and the second hand grip.

A frame for an electric bicycle, such as a long-tail electric cargo bicycle, is described. The bike frame, in some embodiments, includes cross members that connect a rear rack of the bicycle to a head tube of the bicycle via a seat tube of the bicycle. Via the multiple connection points, the cross members mitigate side to side movement, such as waggling, of the rear rack of the bicycle.

The present invention describes a transportation device 1 comprising multiple motorized wheels, for propulsion of the transportation device 1, wherein the transportation device 1 comprises at least one user ride-on unit 50, wherein the transportation device 1 has at least 4 wheels 4L, 4R, 5L, 5R, and wherein the transportation device 1 comprises a frame 70 arranged to provide a standing and/or walking space for the user.

A vehicle for transporting persons and/or goods, having at least one frame which includes of at least one frame element which extends substantially parallel or obliquely to the longitudinal direction of the vehicle, at least one wheel carrier which can be detachably secured to the frame element and which, together with the frame element, forms a receiving region between the wheel carrier and the frame element. The wheel carrier and the frame element are spaced apart from one another at least in sections so as to form a cavity. The frame also includes at least one wheel unit which includes a wheel and can be fixed or is fixed in a rotatably mounted manner at least in sections in the receiving region between the wheel carrier and the frame element.

A foldable human-powered vehicle upon which users can ride is described. The vehicle includes a wheel assembly, a deck assembly, a seating assembly, a handle assembly, a deck support frame, and a brake assembly. The vehicle also includes a first and a second bicycle having a first handle disposed opposite a second handle. A first handle of the second bicycle is affixed to a second handle of a portion of the handle assembly to affix the second bicycle to the vehicle. A second handle of the first bicycle is affixed to a first handle of a portion of the handle assembly to affix the first bicycle to the vehicle. The vehicle also includes a rear component affixed to a portion of the deck assembly, where a head tube of a third bicycle is affixed to the rear component to affix the third bicycle to the vehicle.
