Sorry to miss your reply, Rich.
There have been a few different configurations on road.
There was a motor, glued to the V in the bottom bracket on the mountain bike. An EROS bike motor, with an adapter to the custom cogs Jensen made. And a chain to a right hand crank and cogs, with the pedal tending to unscrew. And a Bicycle Lighting Systems PAR 35 6VDC light. This rig didn't work real well, so I made a motor mount, and got a bigger motor.
The Ametek servo motor is 4" OD and 5" L. See ftp://users.aol.com/DGoncz for photos of the trapezoidal mount with hose clamps, low in the V near the bottom bracket. Not bad. Rode up hill at night with the B.L.S. light.
Then there was the big round disk covering the main triangle. Of 3/4 inch LDF. This allowed for chain drive from the pedals or the rear wheel. The rear gear on the mountain bike was brazed from a steel BMX spider and had a bottom bracket lock ring on it. It mounted to the flip flop hub, relaced to the rim.
With that rig, I added ultracapacitors. Eight PC 2500 2700 F 2.5 V caps from Maxwell, surplus. And a digital dashboard.
The caps were never used on the recumbent. The Ametek motor mounts under the seat back bag on the Thunderbolt. The mount was made of plastic drain pipe. Eventually it became clear that an idler was needed to keep the chain on the rear cog, which was made from a Big Cheese BMX chain ring holder, mounted on a mountain bike disc hub, relaced to the rear rim.
That was the rig in the videos at ftp://users.aol.com/DGoncz. New Year's Eve. 24 watts of Christmas lights on the bike, driven by the Ametek and an inverter.
There was also the AC generator, subject of this thread, painstakingly mounted to the front derailer post. One day, the Ametek drove the inverter which drove the front motor/generaor in motor mode. It was a shakedown.
What I am trying to accomplish is to provide all the electrical needs of an infantry soldier, with reasonable mobility and load carrying ability, on dirt roads, whether riding or stopped, such that the only resupply will be ammunition and food. Currently we resupply a lot of primary and secondary batteries to our infantry. An awful lot. A mobility and operational capability restricting large quantity, in fact.
