I asked around for a long time about two-person mopeds and everyone tld me to get a vespa grande or a puch with 2hp. I never did find either of those but out of the 3 peds I had, one was a Hero-Majestic Panther and that one went pretty good with me and my girfriend on it. It also had back footpegs and a long seat which made it much easier. Theres a guy who usually has them for sale on craigslist that lives in reading, MA but he always wants like $750. But I dont know how much luck you're gonna have putting two people on any moped, me and my girlfriend weighed about 250 lbs between us and I think even that's a stretch for a ped. They just aren't really made for big guys or more than one person.
