All Weather Rain Proof Hubless Ebike With Sunroof
Abstract -
The cycle is one of simplest mode of transportation. Bicycle can be driven by all kind of people like children and senior citizen. But this bicycle facing some issues like old design, balancing, high weight and size. There is possibility to overcome these problems by designing the hubless wheel or Centerless wheel. It will improve the aesthetics of the cycle, increased riding properties. The rear wheel design consists of inner rim and outer rim linked with a independently moving nylon rollers. The input power is given to the rear gear meshed with the internal teeth rack welded with the outer rim.
INTRODUCTION
The bicycle is one of the most common medium of transport used in our daily aspect of life. Bicycle can be driven by all age groups of people from children to senior citizens. The old school type of wheel which is being used for centuries has been given a new design which improves the aesthetics of the cycle. The increased chain length in conventional cycle is the problem for which the driver has to put in more effort for propelling the cycle. The effort put by the driver is high in conventional cycle. There is possibility to overcome these problems by designing the hubless wheel or Centerless wheel. Also the development of hubless crank reduces the effort put by the driver. For development of this hubless bicycle, hubless wheel or Centerless wheel is devoloped. In normal cycle, the steering (i.e) the handle bar is attached to the hub of wheel. But in hubless wheel, the handle bar is attached to the wheel rim which increases steering efficiency. The cycle with conventional look (i.e) cycle with spoked wheel (hub wheels) is always being used everywhere and an alternate for the look is not considered in design. Only the frames and chassis of the cycle has been altered throughout the ages. The wheel has stayed the same. So considering it as the main objective of our project, the hubless cycle is designed.
E Bikes are the future of 2 wheeler transportation as they are highly economic, work without pollution and without noise. But like all bikes have a major disadvantage that they have an open roof which leaves the rider vulnerable to the rain, heat and pollution.
So here we design a solution to this problem with a covered hubless ebike that introduces an innovative hubless design to the Ebike along with protection from rain, heat and pollution. This makes 2 wheelers much more enjoyable and improves the 2 wheeler transport experience.
For this purpose we design the ebike with dual powered DC motors for high torque generation. Now we use a throttle powered controller and battery system to drive the motor as per user throttle. The bike is now run by a hubless wheel design. The back wheel is driven by 2x DC motors so that enough acceleration torque is generated to drive bike and rider.
The hubless design uses rubber roller shaft attached to the motors to drive the rear wheel. The front wheel is supported by a design that uses 2 sets of free rollers to drive the bike while keeping the wheel in place. The bike body is a mixture of mild steel and aluminium to provide a light weight yet strong frame.
The bike body and seat rest on shock absorbers attached to the wheels. This protects the biker and controller from shocks and vibration to a certain level and improve riding experience. The bike frame now involves a transparent sun protect roof, windshield and side doors to protect rider from sunlight, heat, rain and pollution.
Finally the ebike is equipped with high wattage LED headlights, Taillights, Footrest to make the riding experience enjoyable. Thus our All Weather Rain Proof ebike delivers weather proofing with a hubless ebike experience to take bike riding to the next level.
Literature summary
• The increase in steering efficiency compared to the conventional bicycle is observed in hubless bike through survey.
• The efforts put to propel this hubless cycle comparatively less than conventional bicycle.
• The chain drive mechanism is chosen after observation of various experimental studies on possible drive train layouts.

METHODOLOGY
First and foremost is the ideology of the project. Improved aesthetics of the cycle was kept as the vision of the project. As per that, the design conception was framed. The design conception involved the process of welding to be done in areas of joints which kept the wheel assembly firm. Wheel was the main aspect to be considered in the project. The reduction in chain length enhanced the fact of less loss of energy. It will also reduce the fatigue encountered by the driver. The cycle was a conventional cycle. It was amended as per the needs. Then the wheel was separately welded with the rollers placed in he required areas. Next was to weld the wheel with the frame. After welding process of wheel and frame, the cycle was fabricated successfully.
CONCLUSION
Thus the project enhances the aesthetics of the conventional cycle by giving it a good look. The reduction in chain length reduces the fatigue of the rider. The steering has been enhanced. Use of rollers makes the motion of the bicycle more facilitated.
