| I know a little bit about the soubitez model. Back in school I
tried to measure this stuff, but they wouldn't let bikes into the
LABs.
The generator puts out AC. I can tell by the strobe patterns in
the water that flies off the front wheel. Frequency is a function
of speed.
The bulb is a halogen bulb with 6.3V stamped on the side.
If you have the tension adjusted right, there should be no problem
with slippage in rain. I did have some problem with snow however.
The cost was somewhere between 15 and 25 dollars.

| This type of device is compulsory for all bikes here in Switzerland
(except for race bikes where battery run light is accepted).
Therefore all our bikes come with a front and rear (red) light,
powered by a small generator (called dynamo) producing DC. The bulbs
are usually around 6V (they are not hallogene).
It will work as of about 7 mph, and does not fear rain.
These things are to be found in any supermarket
w. bicycle section for about US$ 10.- to 15.-.
BTW, I'm interested to see what kind of accessories & gear are sold on
the other side of the Atlantic. Would anyone mail me a Nashbar
and/or Performance bike catalogue ? Also, woud they mail overseas
(I would charge to a Barclay's card) ?

| 185.3 | there are "reducers" | NOVA::FISHER | | Tue Dec 09 1986 09:00 | 11 |
| I have a Union Generator system which I've used somewhat. It comes with
small rubber thing which you can put on the wheel that contacts the tire.
It's purpose is to reduce the speed at which the generator operates and,
therefore, the power output. A reason that this is desirable is for
downhills, though I don't believe anyone would want to make a habit of
getting onto and off his bike to change the generator output.
A friend actually blew the bulb of his headlight while descending a
mountain at night. Presumably while not using such a device.

| Suggest you take a look at notes 10.*. Good stuff there.
As noted there, I have a Soubitez which I like. Very little drag.
