Hello,
I've been doing a lot of reading on various forums (here, endless sphere and others) on various options for propelling a bicycle.
Electric is extremely expensive, I wouldn't mind but the range is kind of a choker for me.
So, I am hoping to understand how to make a motor as quiet or silent as humanly possible. If I thought there was a 25cc engine for 2000-3000 dollars right now that rivaled the noise levels of an electric setup, I'd jump at it like a warrior.
With that in mind, I am looking into subaru/robin or honda 25cc engines. What I've come across thus far for making things quiet are mufflers for the intake, the exhaust, and pieces of rubber on the cooling fins.
The fanciest muffler I've come across are called vortex cherrybombs. I imagine putting one on the intake and one on the exhaust. I am sure there is some fatal flaw I am missing to these ideas.
I am sorry if this idea/question has been beaten to death, I've read many threads and the details are a bit on the light side.
