The bike was $140 at Walmart, a Schwinn beach cruiser with a built-in, very strong rear rack. The motor kit is a Dax 80cc. The electrical system was built using parts ordered off ebay; the total cost was about $125, including the scooter-style rear trunk. The tail/brake light, headlight, and turn signals are all LED. The battery and wiring are contained in the trunk, with plenty of space left over for storage. I bought a 6-fuse auto fuse box instead of using inline fuses, so the headlight, tail/brake light, and turn signals have their own fuses. I don't know if that's necessary, but I did it anyway because...well, why not? I have a 12 volt, 1.5 amp horn but haven't wired it yet, and haven't mounted the front turn signals yet. All of the parts were made to run directly off the 12 volt battery and did not require any inline resistors to prevent them from blowing, simplifying the wiring enormously. The handlebar-mounted control switch was for a GY6 scooter, purchased off ebay for less than $7. Generic motorcycle rear-view mirrors were $9 for the set. This build was meant to look as much as possible like a real moped to attract as little attention from the police as possible.
Oh, yeah, the trunk has a backrest, which is kind of nice! The reason for the inverted grip shifter on the left handlebar is that the bike has a 7-speed rear derailer, but I didn't want to use a thumb shifter, so I got a twist shifter and simply installed it upside down on the left side instead of the right.
Comments, suggestions, and potential improvements are welcome!
