I've been lusting after a Motoped. The official specs are 49cc and <30mph, but most of them get "well-tuned" before they ever hit the street. It would also make a sweet SHTF vehicle if you had to quickly get out of the city...
These things are EVERYWHERE in the Philippines, and they drive them like maniacs. They also cram 3 people at a time on them, often with small children sandwiched in between two adults.
