An autonomous bicycle comprising an autonomous controller system comprising software associated with monitoring operational processes of one or more electric powered wheels governed by an environmental sensor array and motion sensors contained on framework sections, sensors including; load sensors, deformation sensors, gyroscope sensor, and accelerators, accordingly a power control module provides battery power to the electric motors. The autonomous bicycle configured to independently operate with or without an operator riding onboard. The operator uses their smartphone to manually control or verbally control the autonomous bicycle, the operator accesses a mobile app, customizes user preference settings, whereby software algorithms and user interface instructions allow the operator to control their autonomous bicycle when riding, or summon the autonomous bicycle to drive over to her or him, respectively the operator can utilizes their preference settings to select a custom drive mode with max speed calculated. The operator's smartphone is configured with a user interface system linked to the autonomous bicycle by WIFI or Bluetooth, the operation data and performance data gathered by the operator is saved in memory, Cloud management network, or Global Internet Network providing Cloud Database Management Network(s).

A foldable rotary arm structure and device for a bicycle. The foldable rotary arm structure includes a rotary wheel and a rotary arm. The rotary wheel is coaxial with a transverse tube or surrounds the transverse tube. The rotary arm is in steering connection with the rotary wheel or a supporting base, such that the rotary arm is attached to the transverse tube when folded, thereby reducing the space of the transverse tube occupied in a radial direction. A flywheel for use in a balancing device of a bicycle or a motor-assisted bicycle or an amusement device is provided. In the rotary arm, individual batteries or multistage batteries are arranged in a single layer in the radial direction and are stacked in multiple stages in the axial direction. When the rotary arm is unfolded and rotated, the angular momentum is increased or the torque is balanced.

Bicycle safety exclusion zone systems capable of being attached to a bicycle, comprised of one or more projector-sensor devices and a processing unit. Each projector-sensor device is capable of detecting vehicles in proximity of the bicycle and of projecting at least a portion of a visual safety exclusion zone upon ground surrounding the bicycle. The processing unit is in communication with the one or more projector-sensor devices. When one of the projector-sensor devices detects a vehicle in proximity to the bicycle, the processing unit generates an alert detectable by a user of the bicycle, and the one or more projector-sensor devices change the visual appearance of the visual safety exclusion zone. In some embodiments, the change in the visual appearance of the safety exclusion zone comprises a change of color.

A snowmobile including a warming element at a handlebar of the snowmobile. The warming element is configured to generate heat in response to electrical current driven therethrough. A user interface is configured to receive inputs from an operator of the snowmobile. The inputs include a first temperature input setting a first predetermined temperature for the warming element. A control assembly includes a warmer control button configured for setting the warming element at the first predetermined temperature. A control module is included with the control assembly and in receipt of inputs from the user interface and the control assembly. The control module is configured to, when the first predetermined temperature is selected by way of the warmer control button, direct sufficient electrical current to the warming element to generate heat equal to the first predetermined temperature.
