Last night while returning from my favorite bar, I ran out of gas. Pedaled home 3 miles. It was grueling. The 36/21 tooth chainring/freewheel makes starting very easy, but not so much for making way. I also lowered the seat so I can place my feet down when I roll to a stop. Low seat position, small gears made for a long ride home. I have searched the forum for reserve gas containers and have several options. My question is: Which is the most conveniant? Gas stove fuel bottles, jerry cans, wine bottles or any other suggestions?
