Introduction

We are professional do e-bike kits business for many years for the customers all over the world, and have met so many troubles, with these troubles, we have much experience on e-bike kits today.

 

Our e-bike kits are easy to install and allow you to convert your standard bicycle into an fun and eco-friendly e-bike. Since every model is different and components will vary, it's your responsibility to determine the best way to install an electric bike kit on your bike. Although most of the steps are similar from install to install, we have instructions can help the customers to convert their bicycle.

We have build the Europe after-sale service center in Europe to repair the parts including motor, batteries, controller etc, also for the whole ebikes repairing. As one of the pioneer seller for ebikes in china, BTN aims to master clean energy technique, and develop energy-saving and environmental-friendly ebikes.

Q:How do you see the motor number of the electric car?
Can you provide more detailed information? For example, the electric car brand, model.
Q:Electric bicycle motor brush good, or no good brush, what is the difference between the two?
Brushless motors are currently used by electric bicycle manufacturers, usually brushless brushless motors. Its speed control system cost is higher than the speed control system of the brush high speed motor, and the controller is prone to malfunction in use. Electric bicycle with brushless motor driving must reach a speed of 35 km / hour or more, in order to exert the best efficiency, but we know that the electric bicycle as a non motor vehicle management, must be in the speed of 20 km / h, the brushless motor is electric bicycle with reduced work efficiency, it is not strong. The main thing that is being adopted now is the small noise.
Q:How to measure the quality of brushless motor in electric vehicle?
Measure the motor with a multimeter. If there is a direct current resistance passage, there is no disconnection,Then, turn the motor on both ends of the motor by means of the multimeter voltage register
Q:How to remove the electric motor, what should pay attention to ah?
Before removing the motor, the motor and the controller's lead should be pulled out first, and the corresponding relationship between the lead color of the motor and the lead color of the controller must be recorded. Before opening the cover of the motor, it shall be clean as a site to prevent the sundries from being sucked into the magnetic steel in the motor. Mark the relative position of the end cap and the wheel hub. Attention: be sure to loosen the screws so as to avoid the deformation of the motor housing. The radial clearance of the rotor and the stator of the motor is called air gap (air gap), general motor air gap between 0.25-0.8mm, after the completion of the demolition motor eliminates motor fault, must be on the original cover mark for assembly, which can prevent the two assembly after sweeping phenomenon.
Q:How to measure an electric motor with a multimeter
Measuring controller: turn on the power, turn it, the power and Holzer power should be 4 - 5V voltage, the controller of the three Holzer line potential should be the sameThis is a simple method of measurement,The motor does not turn, usually the circuit fault is in the majority, and next is the brake handle, turn the handle. In the second is the controller, the motor is generally not damaged
Q:Brushless electric motor brushless motor and brushless gear motor which good?
Advantages: from the motor efficiency and climbing performance, said brushless teeth better than brushless, toothless, smaller size.
Q:What is the principle of electric car locks, Holzer? What's the connection between these two?
Mainly used to detect the rotating position of the motor, the main controller to control the speed of the motorPure hand, hope to adopt, thank you!
Q:The electric vehicle operation, the motor suddenly belch belch two times, then walk away.
Also, are you sure the change controller is good and the voltage is the same?. Second, consider your wiring problem.
Q:Can electric cars need no controllers
May, the positive and negative ends of motor connected to a battery, a power supply to open high-speed operation, unable to control the speed, extremely unsafe; will affect the service life of the battery, easy to make the motor brush burn, this is turn is not effective.The role of controller in the electric vehicle, the motor running speed (by speed control switch to transfer speed numerical Holzer element in the structure), braking system, speed display system, speed limits and other functions like human organs, are indispensable.
Q:How to calculate the motor power of electric bicycles?
Batteries have no power, only capacity. Current value / capacity per hour. That is, how much current can discharge a clock
