Re: Advantages/disatvantage Of Friction Drive
Simplicity, low weight, cheap and reliable unless it gets wet. You can take a free weedeater engine and a thrift store bike and use a little creative engineering and have a motorized bike very cheaply. I had very little money in mine. That said I am building a chain drive now for my second bike. It is going to cost me at least 4 or 5 times more than the friction drive.
All times wasted wots not spent ridin. Get a bicycle. You will not regret it. If you live. Mark Twain
