I have a frame or want to convert it into a hub motor.How do I know which motor is suitable for purchase?
A: Firstly,look at the numbers on the tires.Some marks have such numbers as 16*2.125 or 12.5*2.25 or 200*50 or 3.00-10 etc numbers.the 16 is need buy 16 inches,12 is need buy 12 inches.If not clear,please take photo of the tires to our the customer service check.
B:Secondly,look at the width of the Fork.If you want to install the rear wheel,see the middle width of the fork after removing the original wheel.For example,140MM,our description of the opening size is 130MM,then it is can be installed,otherwise it can not be installed, you need to replace the rear fork or Rear fork.
C:Thirdly,If the number of tires is suitable,the opening is also suitable,the rest will see the voltage,the original voltage is how much then buy how much voltage,if you want to change to increase the voltage,it depends on the position of the battery can install enough batteries and then plan .
Basically,these three conditions all suitable,then can be installed.
