Which traffic tool you take to go working in the morning? By bus, MRT, motorcycle or cars? Each of them is common but also has the same problem, it need the fuel; and that means you have to pay. Besides, all of them would generate pollution, I guess that is the reason why bicycle has become the popular choice in many big cities.
Riding a bicycle is quite convenient and healthy, it generates almost zero pollution and is free to park easily. All you have to pay is to assemble your bike with the steel bike frame, wheels, handles and enjoy the fun of DIY your own bike; or you can simply buy the finished one instead. Once you start to ride it, you may feel the difference and fun of riding bike.
It used to be only few choices of bikes, now, there are various kind of choice, the bicycle with carbon or steel bike frame, for riding in the city or mountain, it can be folded or not and etc. No matter which kind you prefer, just remember to choice the one with firm structure for your safety, then you can feel the change and enjoy the benefit of riding bike.
