T-72 Bugatti Cyclemotor on a Peugeot Bicycle
How would like to be the machinist?
It's complexity cannot be overstated. In fact, the amount of detailed machining required to produce the engine would have made this a very expensive little bike. Perhaps as some surmise, this little engine was an attempt at camouflaged luxury made to conform to the societal norms of post-war reconstruction. Unfortunately, no one will know since it never went into production.
