I have three bikes all together. The Moondoggie has a small frame and you can't pull the barrel off with-ought taking out the studs, but other than that, no problem. One thing I would like to hear from someone else that has another larger bike, is about vibration. (Comparing from one bike to another). this bike rides like a motorcycle in that there is no vibration transfered to the frame. Its like one of my little Honda's. The other two bikes have a vibration that is annoying and keeps you from enjoying the bike as it should be. I wonder if is the more compact frame that does it. I am going to try and make another motor mount for the Pacific, that will give it three, and see if that helps. I know on a motorcycle if one of the motor bolts gets loose it will knock the enamel off your teeth with vibration, or crack the frame. Have fun, Dave
