Things are really going slow for my CH80 project. After about 2-weeks of searching for a bicycle that I wanted to do this project on, I decided just to order a Worksman 20" Straight Top Post with front and rear drum brakes. I know i won't be able to use the rear drum on this build though. I am hoping there is enough room for this engine. I am wanting to go with the SBP Shifter after I get all the bugs out of the engine. Everything seems up in the air, at the moment until I recieve this bicycle in about 2- weeks. Has anyone used this type of bicycle for their build?
