Conveyance vehicles such as snow bikes and snowmobiles having an endless track system driven by a combustion engine are enhanced in performance with a torque assist system. The torque assist system includes an electric motor that is coupled to drive the track in parallel with the original internal combustion engine through either its own track drive, or through the drive system of the engine. The motor can be a spindle drive motor or hub motor. Torque assist is generated through a torque assist throttle input coupled to a motor controller. A battery temperature assist system diverts heated cooling fluid from the engine cooling system to heat the battery through its own heat exchanger. The controller is coupled to a processing device such as a smart phone that executes apps configured to provide parametric data to the controller and to receive parametric data from the controller through a user interface.

An electric bicycle includes a frame that has a concave or arc shape. The bicycle also includes two wheels—a front wheel and a rear wheel, with each wheel being connected with an end portion of the frame. A battery-powered electric motor may be connected with the rear wheel to drive the rear wheel and propel the bicycle forward. The battery may be rechargeable. The speed of the bicycle may be controlled by the operator moving a lever with one of their feet. A rotatable knob located on the frame may be used as a cruise control speed setting device. The electric bicycle may be steered by the operator using their feet resting on a pair of foot pegs that are attached to or connected with the front wheel. The electric bicycle may include a regenerative braking system or a friction braking system.

A universal battery is provided with load balancing and a battery module and an energy storage system electrically coupled to the battery module and configured to bidirectionally transfer energy from and to the battery module. The energy storage system is operable in a first operating state in which the energy is transferred from the energy storage system to the battery module to charge the battery module, and a second operating state in which the energy is transferred from the battery module to the energy storage system to discharge the battery module. An electrical connection electrically couples the energy storage system to a power source. A controller is operably coupled to the battery module and the energy storage system. The controller is configured to control a charging state of the battery module.

An intelligent safety frame capable of easily replacing and protecting battery includes a front beam, a battery mounting box, a rear beam, a cushion mounting seat and a rear tail box mounting seat, wherein a rear tail box is mounted on the rear tail box mounting seat, the cushion mounting seat is rotatably mounted on the rear beam, a battery mounting cavity is defined in the battery mounting box, a threading box is provided on a side of the battery mounting box, a first wire-in cavity is provided in the threading box, a first threading slot is provided on a side of the battery mounting cavity, a wire outlet is provided on a side of the threading box, a second intelligent lock mounting slot is provided at the upper end of the rear beam, and a lock catch is provided on a side of the cushion mounting seat.

An electric vehicle includes a frame, a wheel coupled to the frame, and a battery assembly including a housing supported by the frame. The housing includes a top side and a bottom side opposite the top side. A drive assembly of the electric vehicle is at least partially enclosed within a drive housing unit. The drive assembly includes a motor configured to receive power from the battery assembly and a gear assembly configured to transmit torque from the motor to the wheel. The drive housing unit is positioned below the bottom side of the housing.

An on-board locking assembly for a vehicle such as a bicycle or scooter comprising a movable member, such as a rigid bar, movably mounted to the vehicle at a first end and releasable from the vehicle at the second end, wherein a vehicle mounted receptacle is configured to fasten and release the second end, and wherein the rigid bar is configured to be movable relative to the vehicle to capture an object to which the vehicle may be fastened, and optionally obstruct the rotation of a vehicle wheel, and wherein the unfastening of the locking assembly may be controlled by wireless signal. A novel on-board retractable cable lock is also presented.

A structure for integrating a down tube of an electric bicycle with a battery box is provided. The down tube has a tube body and two fixed bases arranged in the inner cavity of the tube body. A receiving cavity is bounded by the two fixed bases and the tube body. The receiving cavity is provided with an access opening on the outer side surface of the tube body. A long side of the access opening extends inward to form an elongated protruding rib. A positioning column is provided on each of two opposite sides of the two fixed bases. The battery box has a box body and two bearing bases that are installed on the outer sides of the two ends of the box body, respectively. A first dimple is provided on the outer side of the box body in a concave manner.
