Developing the Digital Wheel, a new idea for sustainable transportation, is a big challenge. The main goal is to make a kind of transportation that is good for the environment, easy to use, and affordable for everyone. The challenge is to design the Digital Wheel so that it uses clean energy, like electricity or solar power, instead of petrol or diesel, which pollute the air. Another problem is making the Digital Wheel comfortable and safe for people to use every day. It needs to be strong enough for different roads and weather conditions in Bangladesh. Also, it should be easy for people to learn how to use it, even if they haven’t used this kind of transport before. We also need to think about how to make enough Digital Wheels for lots of people to use and how to fix them if they break down. Plus, it’s important to make sure that the cost of the Digital Wheel is not too high, so that most people can afford it. By solving these problems, the Digital Wheel could really change the way people travel in Bangladesh. It can help make the air cleaner, reduce traffic problems, and give people a new, eco-friendly way to get around.
