Alerting riders of electric bicycles to potential hazards

1. An electric bicycle, comprising:

a frame having a head tube, down tube, top tube, and seat tube;

a front wheel attached to the frame via a fork connected to the head tube;

handlebars attached to the head tube and configured to rotate the fork and the front wheel;

a rear wheel attached to the frame via a dropout assembly of the frame;

an electric motor mounted to the rear wheel that propels the electric bicycle;

a battery pack mounted to the frame of the electric bicycle that provides power to the electric motor;

a controller that controls operations of the battery pack of the electric bicycle and the electric motor of the electric bicycle;

one or more sensors attached to the frame of the electric bicycle;

one or more haptic actuators that present haptic feedback to a rider of the electric bicycle; and

a rider safety system stored in memory of the controller and including:

a hazard detection module that receives data captured by the one or more sensors and from an environment through which the electric bicycle is traveling and detects an occurrence of a potential hazard to the electric bicycle or to a rider of the electric bicycle;

an action selection module that selects a safety action based on the occurrence of the potential hazard,

wherein the selected safety action includes an action performed by the one or more haptic actuators of the electric bicycle; and

an action module that causes the electric bicycle to:

perform the selected safety action in response to the detected potential hazard;

determine that the electric bicycle has not performed a hazard mitigation operation; and

perform a different safety action upon determinating that the electric bicycle has not performed the hazard mitigation operation.

2. The electric bicycle of claim 1 , wherein the rider safety system:

determines that the electric bicycle has performed the hazard mitigation operation; and

causes the electric bicycle to stop performance of the different safety action in response to the determination.

3. The electric bicycle of claim 1 ,

wherein the hazard mitigation operation is a braking operation.

4. The electric bicycle of claim 1 ,

wherein the hazard mitigation operation is a turning operation.

5. The electric bicycle of claim 1 , wherein the action performed by the one or more haptic actuators of the electric bicycle includes presenting a pattern of haptic feedback via grips of the handlebars of the electric bicycle.

6. The electric bicycle of claim 1 , wherein the action performed by the one or more haptic actuators of the electric bicycle includes presenting a pattern of haptic feedback via a seat of the electric bicycle.

7. The electric bicycle of claim 1 ,

wherein the action selection module selects the safety action based on the occurrence of the potential hazard and a detected imminence of the potential hazard to the electric bicycle.

8. The electric bicycle of claim 1 , wherein the hazard detection module detects the occurrence of the potential hazard as a potential collision with a vehicle via one or more motion sensors; and wherein the action selection module selects an action of presenting a pattern of haptic feedback via grips of the handlebars of the electric bicycle to the rider of the electric bicycle.

9. The electric bicycle of claim 1 , wherein the hazard detection module detects the occurrence of an object within a path traveled by the electric bicycle via one or more image detection sensors; and wherein the action selection module selects an action of presenting a pattern of haptic feedback via grips of the handlebars of the electric bicycle to the rider of the electric bicycle.

10. The electric bicycle of claim 1 , wherein the hazard detection module detects a presence of multiple potential hazards within an immediate proximity of the electric bicycle; and wherein the action selection module selects an action of presenting a pattern of haptic feedback via a seat of the electric bicycle.

11. The electric bicycle of claim 1 , wherein the hazard detection module detects a dangerous movement pattern of multiple vehicles within an immediate proximity of the electric bicycle; and wherein the action selection module selects an action of presenting a pattern of haptic feedback via a seat of the electric bicycle.

12. The electric bicycle of claim 1 , wherein the hazard detection module detects a dangerous location pattern of multiple vehicles within an immediate proximity of the electric bicycle; and wherein the action selection module selects an action of presenting a pattern of haptic feedback via a seat of the electric bicycle.

13. The electric bicycle of claim 1 , wherein the hazard detection module receives location safety information for the environment from a fleet management server that manages a fleet of electric bicycles that includes the electric bicycle; and wherein the action selection module selects an action of presenting a pattern of haptic feedback via a seat of the electric bicycle.

14. A method performed by a rider safety system stored in memory of a controller of an electric bicycle, the method comprising:

receiving data captured by one or more sensors of the electric bicycle and from an environment through which the electric bicycle is traveling;

detecting an occurrence of a potential hazard to the electric bicycle or to a rider of the electric bicycle;

selecting a safety action based on the occurrence of the potential hazard;

causing the electric bicycle to perform the selected safety action in response to the detected potential hazard;

monitoring, by the rider safety system, operations of the electric bicycle after performing the selected safety action;

determining that the electric bicycle has not performed a hazard mitigation operation in response to the performance of the selected safety action; and

causing the electric bicycle to perform a different safety action in response to the determination that the electric bicycle has not performed a hazard mitigation operation.

15. The method of claim 14 , wherein the selected safety action includes an action performed by the one or more haptic actuators of the electric bicycle to provide haptic feedback to a rider of the electric bicycle.

16. The method of claim 14 , wherein the selected safety action includes an action performed by the one or more haptic actuators of the electric bicycle to provide haptic feedback to a rider of the electric bicycle via grips of the handlebars of the electric bicycle.

17. The method of claim 14 , wherein the selected safety action includes an action performed by the one or more haptic actuators of the electric bicycle to provide haptic feedback to a rider of the electric bicycle via a seat of the electric bicycle.

18. A non-transitory computer-readable medium whose contents, when executed by a rider safety system stored in memory of a controller of an electric bicycle, causes the rider safety system to perform a method, the method comprising:

detecting an occurrence of a potential hazard to the electric bicycle or to a rider of the electric bicycle;

selecting a safety action based on the occurrence of the potential hazard,

wherein the selected safety action includes presenting haptic feedback to a rider of the electric bicycle;

causing the electric bicycle to perform the selected safety action in response to the detected potential hazard;

determining that the rider of the electric bicycle has not performed a turning operation or a braking operation in response to the selected safety action;

causing the electric bicycle to perform a different safety action;

determining that the rider of the electric bicycle has performed the turning operation or the braking operation in response to the different safety action; and

causing the electric bicycle to stop performance of the selected safety action and the different safety action in response to the turning operation or the braking operation.
