Whether you’re cranking the throttle, hitting the pedals or both, a shift of gears provides easier climbs or declines in grade, with less of a toll on the bike’s battery.
不管你是要扣紧刹车、要蹬踩踏板或者两者同时，变速轮之间都可以轻松变换以顺利实现提速或减速，而自行车的电池耗电会比较少。
A battery provides the electric power to operate the starting motor and the ignition system during cranking.
在启动时，蓄电池提供电能能使启动电机和点火系运转。
Moreover, a battery based on this system won't overheat during high-rate cycling and easily achieves 5-kilowatt cold cranking at minus-30 degrees Celsius.
此外，在这个制度并没有过热，在高倍率循环，容易达到5千瓦的冷启动在零下30摄氏度的基础上的电池。
When the ignition key is turned against spring pressure past the on position to start, the starting contacts close. This connects the cranking-motor solenoid or magnetic switch to the Battery.
转动点火钥匙，弹簧的压力使“开启”位置变为“启动”位置，起动接触器闭合，使得起动电机线圈或磁性开关与电池接通。
