However, science and technology are two different social cultures, and the differences between them are obvious. The basic task of science is to know the world and find it, thus increasing the intellectual wealth of mankind. The basic task of technology is to discover the world and invent it to create the material wealth of mankind and enrich the spiritual and cultural life of human society. Science answers questions about "what" and "why"; The technology answers the question "what to do" and "how to do". Therefore, the results of science and technology are different in form. Scientific achievements are generally expressed as concepts, laws, papers and other forms. The technical results are usually in the form of process flow, design drawing, operation method and so on. Scientific products are generally not commercial and technological achievements can be commoditized. Modern technology has a strong utilitarian and commercial color.
In a lot of E-bikes nowadays (mine included) battery fits from the frame or hangs from your rack at the back of the bike. In both cases jetski from the weight low and possesses an inferior relation to the centre of gravity, which from general observations, I felt was compromised in case a big clunky battery was perched high up on the rear luggage rack. A battery that can be easily taken out of the frame, as many from the good ones can, is extremely desirable i believe. If you were not sure whether your E-bike would make it to work and back one charge, it is just reliant on taking your charger together with you (they may be being a laptop charger) and charging your battery in the office or workplace. You can assure the boss that the full charge costs about five cents or thereabouts with a good bike. One last thing on batteries. A battery charge indicator is very handy for suggesting the quantity of impose a fee have in the battery when you put down.
