As a special battery powered mountain bikes is transportation have specific requirements:

Cheap: some new chemical power such as hydrogen fuel cell lithium nickel batteries, etc., because the price is expensive, difficult to be accepted by consumers in the near future,battery powered mountain bikes lead-acid batteries and other high-performance battery compared to the absolute electric powered trikes price advantage. Reliable performance, especially require large current discharge performance, over-discharge capacity exceeds 1.75V cordon without damage reaches 1.5V, so that it can withstand high current charging, fast charging with anti-performance. Charge-discharge cycle life.three wheel bicycles Sealed maintenance-free. Lead-acid batteries are with the above requirements, therefore, lead-acid batteries for electric vehicles become the main power supply. You can basically meet the needs of tandem electric bicycle consumers on the electric car industry, however,battery powered mountain bikes the market's ability to expand, electric cars in the proportion of bicycles can greatly improved, is still the most important factor to improve the specific energy and battery life at long. This is why many consumers worried about the main issues. Fortunately, many domestic and foreign interested in electric vehicles energy experts after long research, has made remarkable achievements, such as in recent years, the company used a new sealed lead-acid gel batteries. Through the use of proven, battery life have a more substantial long. With the development of technology, nano-based material used in the lead-acid battery, so the battery life is extended to 2-3 years, is entirely possible.
