Embodiments of the present invention include to a two-tier structural frame for a three-wheeled cargo bike. The structural frame can be the platform for the entire bike and includes both steering and suspension parts. The frame of the bike and its related suspension and steering parts provide stability, durability, and comfort while in motion under human pedal power, as well as motion from a hybrid of human pedal and electric-assisted power sources.

A straddle vehicle includes: a body frame including a main frame extending rear-downward from a head pipe, a pivot frame extending downward from the main frame, and a lower frame which extends downward from the head pipe and extends rearward, and further, is connected to a lower portion of the pivot frame; a side stand which supports a vehicle body during parking; and a main step on which a foot of a rider is placed. A side stand bracket for supporting the side stand includes a first fixing portion connected only to the lower portion of the pivot frame and a second fixing portion connected only to a main step bracket for supporting the main step.

An electric parking stand has a frame (100), a leg assembly (200), and a planetary gear motor (300). The frame (100) has a pair of end plates (110) and a plurality of supporting rods (120) connected between the pair of end plates (110). The leg assembly (200) is pivoted with the respective end plates (110), and the leg assembly (200) has a sector gear (220). The planetary gear motor (300) is fixed to the supporting rods (120) and engaged with the sector gear (220). Thereby, the preassembled electric parking stand could be installed onto a motor cycle by screwing the respective end plates (110) to the motor cycle.

Motorized hub assemblies for use with platforms and the corresponding motorized platforms are presented. At least one of the hub assemblies can be a motor and can contain an internal motor to propel the platform when activated. In some embodiments, the motorized platform has two sets of motorized wheels or two sets or motorized treads for differential rate maneuvering. In some embodiments, different base platforms are mounted to a single set of wheels or a single tread to provide a sporty style ride. A handlebar can also be implemented for greater stability. In all cases, there is no requirement for an electronic stabilization platform.

An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. The autonomous electronic bicycle can receive a destination and determine a route from the current location to the destination. Using a set of sensors, the autonomous electronic bicycle can detect obstacles in proximity of the autonomous electronic bicycle and determine a target path for the autonomous electronic bicycle through the environment.

Similarly, the autonomous electronic bicycle can comprise a set of sensors used for autonomous navigation. The autonomous electronic bicycle can operate autonomously, traveling to a chosen destination by controlling at least the first, second, and third electronic motors. The autonomous electronic bicycle can further be manually ridden by a rider as a traditional bicycle.

Similarly, the autonomous electronic bicycle can comprise a set of sensors used for balance. The autonomous electronic bicycle can use the balance sensors to determine a current state of the autonomous electronic bicycle and drive the electronic motors to balance the autonomous electronic bicycle and achieve a target pose of the autonomous electronic bicycle. A neural network can be trained to determine one or more motor outputs of the autonomous electronic bicycle based on the target pose and the current state.
