Allstate: sweet bike. I would love to have one. I was thinking of the more common Puch Maxi, Motobecane Mobylette, and Puegeot (102 and 103 I think) In looking at moped front forks, keep in mind that most of them have springs, but no shock/dampener. There are a few with dampeners aka "Hydros". As I'm sure you know, most mopeds use 16 or 17" rims, with a tire diameter around 21" to 23". You are likely to have clearance issues with larger tires. The early mopeds from the 1950's had larger tires, sometimes 19" or larger. Tires are expensive for those, but outperform bicycle tires at speed.
