American lightweight Motorized Bicycles

It's all out there, I'm just a happy nerd, finding some of them. I'm wondering when I'll find a hydrostatic drive hub on a bike.

It is kind of sad that AMF represents what America came up with for a moped. The ones that had the engine on the rack behind the seat were really ill-conceived using a McCullough chain saw engine and had a top speed of around 15mph. Even more weird was that Harley Davidson sold them. I imagine that is something that H.D. would like to forget.

I bought one of these a few years ago as a parts donor as it has nice drum hubs on it. I ended up hanging a Tomos 2 speed engine under the frame and turned it into a nice bike with full sized wheels and a Suzuki fork. I intend to finish it up this winter and give it to my son. But as it was sold when new... what a dud.

Don't worry, British manufacturers came up with at least the equal of the AMF. Given their effect on all the things they touched, we can make a reasonable supposition about the MF part of AMF. What did the A stand for?
 
You can get a 50 made in America. The engine on it's own might even be affordable. Better yet, it will be designed for more power than you'd reasonably need on a bicycle frame. By Cobra Moto.

Harley-Davidson was forced. AMF was their corporate overlord at that time.

Do you recall also those cheap, Taiwanese-made, 2 stroke dirt bikes they marketed as a Harley?

I'm sure Harley would like to forget those days. More than that; they're probably downright humiliated over it.

That was no one's finest hour.
 
I didn't know about Taiwan, I knew about the Aermacchis where they stuck HD on the tanks.

Sorry. I should have made it clear that Taiwan was just a guess. Korea would have been my second guess.

I'm not familiar with Aermacchi. Who are they and where are they from?
 
Italian, originally, as the name implies, aircraft manufacturers, like Piaggio, who got into bikes to earn money post WW2.

They made 90cc 2 stroke minibikes for HD as wll as the flat single 250/350 sprint models. Later on, there were 2 strokes replacing the 4 stroke singles.

After various traumas and disasters, the bones still exist as Cagiva, still out there, still racing and making road bikes.
