Background

About 4 years ago I snagged a ratty General 5-Star with a trashed Sachs motor. Had big dreams for it, especially to make it quite fast, but while keeping a fair amount of moped-inspired DNA - namely 50cc single-speed. I also wanted it to look "good" but have form follow function. And vintage moped parts weren't necessarily a requirement for me, neither were pedals (although sweet if I can incorporate either!).

The main goals for this project were and are to:

Practice and improve my fabrication and design skills, working around the limitations of not having more than hand tools and small power tools (at most a drill press) at my disposal. I do have a TIG machine, tho.

Push the limits of what a single-speed 50cc power plant can provide, with some balance of acceleration, top speed, and durability (in no way, however, was I expecting thousands of miles free of maintenance - although limiting maintenance mostly to the clutch would be nice).

Give the build some level of "professionality," and dare I say engineering; or at least thinking things through on a ballpark-level so they work well the first time, and so the bike is solid without being overbuilt. Enough to be nice, nothing extraneous - for everything, a purpose.

And maybe make it look nice.

The bike looked like this when I got it:
