Dual drive to single and dual drive switch & controller kit( A pair)

Dear customer, if you want to change your dual-drive electric bicycle to a switchable mode between single-drive and dual-drive, or you want to install a motor switch on your dual-drive electric bicycle to turn off the operation of the front motor. You will need to purchase a special controller and motor switch to retrofit. This modification is only for customers with strong hands-on skills. If you don't know how to modify it yourself, please don't place an order easily.
