## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention relates to bicycles and more particularly to a bicycle including a control assembly mounted on a saddle, a display assembly mounted on the handlebars, and an auxiliary assembly mounted on the saddle and the handlebars.
2. Description of Related Art
Bicycles are a convenient, low-cost and environmental friendly form of transport. To enhance strength, comfort and functionality of bicycles, many auxiliary devices have been proposed. For example, there is a device incorporating rear-view mirror(s), a camera, and a display mounted on a bicycle. While it is simple, it is not practical.
The danger of riding a bicycle is about the same as driving a car or a motorcycle. It is suggested that front and rear lights should be installed on a bicycle. But it is often that a rider forgets to turn on the lights in the night. Further, there is a need of installing a stand on the handlebars or some part of a bicycle for anchoring a mobile phone or a music playing device so that a rider may listen to music while driving.
In light of above, the need for improvement of a bicycle still exists.
SUMMARY OF THE INVENTION
It is therefore one object of the invention to provide an intelligent system for a bicycle including a saddle, a frame, two wheels, and handlebars, comprising a control assembly mounted on the saddle and including a saddle control device, a sensor device, a digital camera, a lighting device, a warning device, and a power supply for supplying direct current (DC) power to the saddle control device, the sensor device, the digital camera, the lighting device, and the warning device for electrical interconnection; and a display assembly mounted on the handlebars and including a liquid crystal display (LCD) screen, a processing module, a communications module, and a power module for electrically interconnecting the LCD screen, the processing module, and the communications module; wherein the saddle control device includes a microprocessor, a memory, and a wireless communications module electrically interconnected; the sensor device includes an optical sensor, a thermometer, an acceleration sensor, a barometer, a gyroscope, an electronic compass, a radar, and a global positioning system (GPS); the digital camera includes a rear camera; the lighting device includes an auxiliary light, a rear light, a directional light, and a decoration light; and the warning device includes a loudspeaker and a vibration module.
The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION
Referring to FIGS. 1 to 4, an intelligent system 1 for a bicycle 2 in accordance with the invention comprises the following components as discussed in detail below.
A control assembly 3 is mounted on a saddle 21 of the bicycle 1 and includes a saddle control device 31, a sensor device 32, a digital camera 33, a lighting device 34, a warning device 35, and a power supply 36 for supplying direct current (DC) power to all of the above components so that they can be electrically interconnected.
A display assembly 4 is mounted on handlebars 2 and includes a liquid crystal display (LCD) screen 41, a processing module 42, a communications module 43, and a power module 44 all electrically interconnected. The LCD screen 41 is a touch screen panel. Alternatively, the display assembly 4 is replaced by a smart phone or a tablet computer.
The saddle control device 31 is used to compress or decompress video files and audio files, transmit or receive data, perform numerical analysis, and perform automatic control. The saddle control device 31 includes a microprocessor 311, a memory 312, and a wireless communications module 313 all electrically interconnected. The sensor device 32 includes an optical sensor 321, a thermometer 322, an acceleration sensor 323, a barometer 324, a gyroscope 325, an electronic compass 326, a radar 327, and a global positioning system (GPS) 328. The optical sensor 321 is used to sense brightness of the environment. The thermometer 322 is used to measure temperature of the saddle 21. The acceleration sensor 323 is used to sense acceleration of the bicycle 2 when riding. The barometer 324 is used to measure atmospheric pressure of the location where the bicycle 2 is riding. The gyroscope 325 is used to measure orientation. The electronic compass 326 is used to show direction of the bicycle 2 when riding. The radar 327 is used to determine distance of a following vehicle. The GPS 328 is used to show location of the bicycle 2 when riding.
The digital camera 33 includes a rear camera 331 mounted on a rear end of the saddle 21 for recording images from rearward. The lighting device 34 includes an auxiliary light 341 mounted on the rear end of the saddle 21, a rear light 342 mounted on the rear end of the saddle 21, two directional lights 343 mounted on the rear end of the saddle 21, and decoration lights 344 mounted on the rear end of the saddle 21. The warning device 35 includes two loudspeakers 351 mounted on the rear end of the saddle 21, and a vibration module 352. The loudspeakers 351 are used to make sounds or voice, issue an audio warning, or play music. The vibration module 352 is used to vibrate the saddle 21 for alerting purpose.
The display assembly 4 is used to show images and data sent from the saddle control device 31 or set the saddle control device 31. The wireless communications module 313 wirelessly communicates with the communications module 43 in the form of Wifi, Bluetooth, mobile phone access to the Internet, or electromagnetic wave of 2.4G wide band. The power supply 36 is rechargeable. For example, the power supply 36 is a rechargeable battery, a solar cell, a dynamo, or a combination thereof. The power supply 36 is mounted on the saddle 21 or the frame 23 if it is implemented as a solar cell. The power supply 36 is mounted on the wheel 24 if it is implemented as a dynamo.
An auxiliary assembly 5 is mounted on both the saddle 21 and the handlebars 22 and includes a microphone 51 mounted on the rear end of the saddle 21 and being in electrical connection with the saddle control device 31 and the power supply 36 so as to record voice, a ring button 52 mounted on the handlebars 22 and being in wireless communication with the saddle control device 31 for activating the loudspeakers 351 or not, and a light switch 53 for activating the auxiliary light 341, the rear light 342, the directional light 343, and the decoration lights 344 or not.
