Self Balancing Electric Bike

What is Self Balancing Electric Bike

An electric bike as the name suggests it runs purely on electrical energy, lithium-ion batteries power the integrated DC motor and also charges using solar energy. Self Balancing Electric Bike Another feature is the gyroscope sensor, which balances the bike in an upright position.

Electric bikes are plug-in electric vehicles with two or three wheels powered by electricity. The electricity is stored on a rechargeable battery, which drives one or more electric motors. Electric bikes (as distinct from motorcycles) have a step-through frame.

An Electric Bike is a battery-operated vehicle that is very economical with low cost, low maintenance, and zero pollution. This bike uses the electrical technology of a rechargeable battery that converts the electrical energy into mechanical energy. The battery can be charged easily using a power connection.
Green energy bikes use rechargeable batteries, electric motors, and some form of control. It can be a simple as an on-off switch but is more usually an electronic pulse width modulation control.

Disadvantages of a Conventional Bike

The increasing fuel consumption throughout the world can be the main reason for the creation of electric vehicles nowadays. This is caused by the depletion of raw petroleum oil source in the world. To counter this problem, the government has taken initiative to reduce and minimize the dependence of oil sources as fuel for energy by introducing renewable energy, green technology, and others. Many researchers from Non-Government organizations (NGOs) and universities especially UTeM are developing green technology projects.

The problems due to which this project is designed:

1. High fuel cost:
2. The ever-increasing cost of fuel.
3. Transmission:
4. Problems in gear changing and clutch.
5. High maintenance:
6. Conventional bikes have high maintenance, meaning more money out of your pocket.
7. Security risks:
8. Can be easily stolen.
9. Accident risks.
10. Hazardous emissions.

Aims of Electric Bike

We aim to design and create an energy-efficient electric bike that can replace the conventional bikes that use internal combustion engines.
To create an economically viable, noise, and pollution-free environment with the launch of battery-powered electric two-wheeler bike and to be product leader through the state of art manufacturing technologies & processes.

Objectives

Normal E-bikes cannot run for very long, are used for short commutes, and need to be recharged very often almost after one or two rides. Our objective is to increase the distance by increasing the battery life by Renewable energy sources and also keep performance and security at their maximum.

How to Make Self Balancing Electric Bike

The block diagram shows that the DC motor is controlled by the controller which is user-controlled by the throttle, the rechargeable battery powers the controller and motor, the battery is recharged through the ac battery charger and also by the MPPT controller which utilizes solar energy.
The block diagram shows that the Arduino UNO which is the controller for the system controls the driver circuit which powers the actuators, the movements of the actuator determine the tilt axis of the bike that is sensed by the accelerometer MPU-6050 which is in a closed loop with the controller, in a closed-loop control system.

The Efficiency of Self Balancing Electric Bike

The energy required to overcome sources of resistance to propel a typical e-bike. These energy requirements were calculated assuming a 35kg bile and 70kg rider on typical e-bike tires. Hill climbing and acceleration are intermittent, while air drag and rolling resistance are present at all times that, the bike is in motion.
An e-bike motor on the theoretical bike would need to supply around 275W watts to maintain 30kmph cruising speeds. A typical e-bike motor size is 350W, which should provide enough power to accelerate to 30kmph on flat ground and maintain moderate speed on hills.
Efficiency drops rapidly with speed. Wind resistance is the most important factor. If an e-bike’s assistance is limited to 30KMPH, and the rider always accelerates to this speed when possible, the e-bike might have an overall flat-ground cruising efficiency of about 70 miles per kWh or about 1.4 kWh per 160 km. At 15 KMPH, cruising efficiency nearly triples to 291 km per kWh or 0.5 kWh per mile.

Intermittent hill climbing and acceleration will reduce overall efficiency in real-world scenarios. Some energy exerted for acceleration and hill-climbing will be recovered while decelerating or rolling downhill, though much will be dissipated as heat while braking.

Future Improvements 

We should pay close attention to the safety of the e-bike and its use. They work on several improvements such as a lower entry-level of the bicycle, a better image for mirrors on the e-bike (lessen the taboo), the reduction of the weight of the e-bike, and having the weight as low as possible in order to improve balance and more subtle support. Also, attention is being paid to the possibilities of tricycle e-bikes, which should be more interesting for people with balancing problems.

Pollution Eating Bike

Another new concept with e-bikes is the idea to develop an e-bike that is not only cleaner for the environment than a car but is even used as a machine to clean polluted air. This example from Light frog creative studio has a handlebar-mounted air filter and a photosynthesis system that can generate oxygen with its lithium-ion battery, which powers the e-bike.  Our project can be further developed from self-balancing to a self-driving bike much like an autonomous vehicle.  

Conclusion

Self Balancing Electric Bike is designed so that it can deliver high performance and reduce carbon emissions making it an eco-friendly mode of transport and gives good mileage and also reduce the risk of accidents by adopting various security and precaution measures.
The issues associated with electric bikes may be addressed by custom-designed drives that are most efficient over a given operating cycle. These include city bikes, hill bikes, distance bikes, and speedy bikes.
The result of the project is to serve a platform to improve the performance of an electric bike. if a new driving system is designed and parameters that will result in improvement of the system performance and they can be used for comparison of existing drives in a systematical, comprehensive, and technical way.
