1.Magnetic motor lock
the anti-theft devise on this electric bicycle is a magnetic key that provides protection. It physically locks the rear wheel through the brake assembly.This devise fixed on the motor , so install motor and rear wheel is the only way to use bicycle without magnetic key.

2.Emergency switch
From motorcycle idea, Emergency switch could stop motor immediately to ensure safe鈥.. Emergency switch (the red button above) allows for quick shut off of the motor system in case of emergency. Suppose .
3.Double speed design (Speed shift)
The double speed function is achieved by the CPU motor and controlling system. 20-22Km/h speed is designed for Japanese and European market and 30-32Km/h speed is for American and Canadian regulations. Speed function is selected by the green button shown above.

4.New drum brake & wide tire
Luyuan top grade models adopted new drum brake with high efficiency and little noise. Some models designed with broad tire??2.5 inch??for more driving inspiration.

5.CPU-motor
Here at Luyuan we have developed an advanced programmable CPU motor with power linearity output characteristic. On condition of limiting total power, the strong CPU motor could increase output torque greatly (up to 50Nm) and at the same time an increase in the distance you can travel for a given battery size. Our brushless motors are precision engineered with high quality components. A very long and reliable lifetime of the motor is achieved through our advanced design and quality bearings. Furthermore CPU motors are very low noise and high efficiency.

6.BM-online charger
BM charger has absorbed 鈥渋ntelligent charging鈥 and 鈥渙n-line maintenance鈥 functions from BTM technique. Our intelligent charging system ensures that on every charge cycle the lifetime of the battery is maximised. Some top-grade models are equipped with BM on-line charger.

7.EABS-Electric Absorption Braking System
We now also provide regenerative braking systems (EABS). Instead of wasting the energy of braking we now use our motor as a braking device. The motor when used for braking will generate electricity hence transforming the wasted energy of braking back into the batteries as usable energy. That is the motor will transform from initiative driving power to passive automatic damping set in braking, and the power accompanied with motor will transform to electric power. Up to 4 amps of current can be supplied back into the batteries when you are braking or going down a steep hill. Thus the range you can travel on our bikes is substantially increased.

8.Introduction of Brushless DC Motor Controller
鈪 The Basic Principle of Controller
Hall rolling handle (also called speed-adjusting handle) or assist power sensor sends out speed instructions, then the controller control motor accordingly to the instructions to run in the corresponding speed by adjusting PWM which is upper MOSFET. Starting-up, running process of large load is controlled by maximum battery current. In the operation, based on the detected Hall signal, it adjusts output power of driver.
