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.

A pedal bar system includes a frame, a motor, a pedal shaft, a pedal assembly, and a tensioner. The motor is selectively operable in a forward mode and a reverse mode and is disposed on the frame. The motor shaft is rotatably coupled to the pedal shaft via a drive belt. The pedal assembly is rotatably coupled to the pedal shaft. The tensioner, in communication with the motor shaft and the pedal shaft via the drive belt, has a disengaged position and an engaged position. When the tensioner is in the disengaged position, the drive belt has insufficient tension to rotate the pedal shaft. Conversely, when the tensioner is in the engaged position, the drive belt has sufficient tension to rotate the pedal shaft. Importantly, the pedal shaft is not rotated by the motor in the reverse mode when the tensioner is in the disengaged position.

Various powered unicycles are disclosed. In some embodiments, the powered unicycle includes a central wheel, a motor to power the central wheel, and a control system configured to control the application of power from the motor to the central wheel. The unicycle comprises a body portion and at least one platform for supporting the user. The unicycle can includes a handle that extends upwardly to a position that it can be grasped by a user of the unicycle. The handle can be partially or fully retractable into the body of the unicycle. In some configurations, two platforms upon which the user can stand are provided with one on each side of the central wheel. In some configurations, a pair of auxiliary or outrigger wheels is provided, such as with one outrigger wheel on each side of the central wheel.

An all-terrain vehicle has an air ventilation system positioned adjacent a rearmost point of the front ground engaging members and directing air rearwardly through an engine compartment, wherein the air ventilation system includes at least one air scoop adjacent a front of the vehicle for directing the air. In addition, an ATV is disclosed having a rear rack having an integral storage bin, where the storage bin is one piece with the rear rack. The storage bin is sealed.

The rainwater collection device: 1) pumps accumulated rainfall from one or more storage containers into a reservoir; and, 2) pumps irrigation water from the reservoir to one or more plants identified by the user. The rainwater collection device mounts on a wheeled cart that readily transports the accumulated rainfall throughout the space of a domestic garden. The rainwater collection device comprises a reservoir, a distribution system, a plurality of hoses, and a cart. The reservoir, the distribution system, and the plurality of hoses mount on the cart.

Embodiments of a smart mobility aid device may have sensors to collect, monitor, analyze and represent data including but not limited to activity tracking, biometrics and safety and emergency features. The activity tracking include number of steps, miles, and activity speed, user pressure on a device, activity types and analysis. The user biometric data includes but is not limited to blood work, blood pressure, blood sugar, heart rate, oxygen level/rate, ECG, EMG, muscle strain, humidity, UV, body temperature. Additional features include an emergency button, fall detection, warnings, and user pattern analysis changes. The mobility aid device is connected to other smart electronic devices and/or the Internet using but not limited to Bluetooth, Wi-Fi, and or/and SIM card. The device gives the user or/and caregiver live feedback about user health metrics and status using a data representation method.
