The DC connector fitted to the Blinder E & X light heads and the Blinder 10k Battery is 3.5mm x 1.35mm ( 3.5mm being the outer barrel diameter & 1.35 the inner pin diameter ).
For our E bike range, the motor end of the included cable (that connects to your bike) is not fitted with any connector and is simply bare wire, for versatility. We do not stock connectors or parts that will be specific to individual bike or motor brands / models.
If your bike requires a specific connector in order to fit the cable to the motors auxiliary light output, we would recommend contacting your bike or motor manufacturer, or getting in touch with a local bike shop / mechanic that specializes in your bike or motors brand.
