I just finished building a motorized bike I bought off the internet. It's a 26" beach cruiser with a 66cc 2 cycle engine. It will go about 30 mph and around 98 mpg, less when I get every thing on it. I'm storing it in the back of my truck with all the extras, gas, oil, tools etc. I also have a bicycle cart that will haul 160 lbs to but my gear in. I'm on the road away from home a good bit and my need this to get back home especially if we get hit with an EMP. I was going to store a bicycle in the back of the truck anyway and thought why not put a small motor on it. I've read where some folks have been getting 4-5000 miles with these little engines. I figure if it takes a dump along the road I'll remove the chain and use the bike with out it. I went on a 30 mile cruise today and it worked great, I'll carry a siphon hose and some extra 2 cycle oil, I figure if we did get hit with an EMP there will be a lot of cars abandon along the road so gas shouldn't be a problem. I think the biggest problem will be getting around people that would like to (borrow) my transportation. I listened to a prepper say the other day, the biggest problem preppers will face is getting separated from the preps. This is not my bike, however its the same thing Update, this is what the rig looks like inside my truck. I have taken the front wheel and handle bar off and Velcroed them to the bike. The white bucket holds the oil, siphon hose etc. I will carry the gas inside the cart along with my bug out gear.
