I have a mid drive ebike.The problem that i am facing is that my chainrings/sprockets do not last long. I am planning to upgrade the ebike so that it can use motorcycle sprocket/freewheel and cogs. I already bought two 49t 428 chain sprocket to use in the mid section and I found a 14T 428 chain sprocket with keyway that will fit on my motor shaft but it does not have the freewheel motion.
The main issue that I have now is trying to find a custom made regular 34mm inner diameter bicycle single speed freewheel sprocket equipped with teeth made to fit the 428 motor bike chain that will screw onto my back hub
Can someone help me in this regard.
Also if you could help me locate a 14T 428 chain freewheel sprocket that can fit the motor shaft i would greatly appreciate it.
My motor shaft is 20mm with a keyway. Below is a picture of my current freewheel, i just want the same thing but with teeth for 428 chain.
