During a standard test, when an electric bicycle runs regularly, the moto current is about 3.5 - 5 A(to 36v moto,different moto may vary). In the condition of starting, against the wind,over-loaded, the required current may rise up to 10 - 15 A.So to those customers who startup frequently,run on a slopping road,or require appropriate overloads, the motos they use require a higher efficiency in the range of   8-15 Ah.

     The brushless, high-speed,flexible-decelerated moto, developped by Zhejiang University Tongxin Electric Technology Company. It sets a whole new world of decelerating structure. Its structure is a development of Planet decelerating with single layer, and its hub is made of high shake-absorptive ,light weight, quite environmental Alu-Meg Alloy material. The whole moto is quite light weight,small size.It is the most ideal motive moto by now. The max diameter is only 118mm, the weight is only 2300g, and the struct is optimized. The front moto is already developped,its width is 101mm, fits for ordinary bicycle front fork It's the smallest,most light,most lovely moto.
