Electric bikes have become more popular; given the hike in Brent crude, thats not exactly surprising. People prefer bikes to other means of transportation because they are fast, reliable and environmental friendly. The great thing about electric bike motors is that they can be mounted on any regular bike.
A battery usually powers the electric bike motor. There are some things you need to know about the electric bicycle battery before deciding which one suits you. Generally, the power of the battery is decisive when choosing one motor over another.
Also, the electric bicycle battery efficiency is crucial. Overall efficiency is usually measured by dividing the watt per hour used by the battery charger by the mileage achieved. This varies highly according to terrain, the weight of the rider and his or her riding style, the type of the battery and the charger.
There are also certain batteries that recharge when you coast downhill. Such a battery is the Canadian BionX. This battery uses road friction in order to recharge. This is very efficient, as you do not need to plug it into a socket in order to have power. It gets as much power as you can generate while cycling.
When trying to choose the best electric bicycle battery, you will have to see which one will last longer. Lead-acid batteries are cheaper and easy to recycle, but they have a very limited life. The nickel cadmium ones will give more power, but they are rather expensive as the cadmium is a known pollutant factor and it is very difficult to recycle. In other words, more power usually translates to disposal problems.
Nowadays, 95% of electric bikes come with lithium-ion batteries. They give a lot of power and are not as difficult to recycle as the cadmium batteries. They come with some problems, but they are rather insignificant as compared to the advantages those batteries bear.
