I have run into somethings that don't want to take to welding. So before I ruin a rear sprocket on a wheel can anyone tell me if a standard chain ring will accept a welding bead. I want to tray welding one to a coaster bike sprocket.
why you ask? I think that if I had a larger rear sprocket I could increase the efficiency of an electric friction drive, why would i think that you ask.
Because when the bike bleeds off speed on a hill it has to get very slow for my current pedal ratio to catch up. In other words it free wheels until the pedestrians can pass me. I think if I could pedal assist sooner and even longer if I want, it will help. I know I could just get a mountain bike to put the drive on, and I would for anyone else, but for me I want to keep the 20" wheel on the rear.
