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.

If you posted all that in English u might get more feedback.


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.

I would start at this point if I were you, because I think your idea of
a way to do it is fundamentally flawed.

Using a soldier to manually generate electricity will impose
substantial extra physical demands on him. This means healthy soldiers
will cover less miles, do less work, arrive more tired, and generally
make them an inferior fighting force. Hardly what you want in your
military!

The whole idea with power is to have the power help the user, rather
than the user slave away to produce the power. One helps, the other
hinders.

This issue makes your whole approach a dead duck in most situations. It
may have its apps, but will be deprecated in most situations.

More logical would be a solar panel on the bike. Even supplying endless
batteries is better that pedal power, when you can provide those
supplies.
