Is there any reason I can't have a front hub dynamo on a trekking bike 
with front suspension, if I wire it both ways and leave a bit of slack 
in the lead?  Has anyone done this?

The bicycle is just as good company as most husbands,
and when it gets old and shabby a woman can dispose of it and get a new one.

The Grasshopper recumbent I had back in (<checks>) 2006 had both a
suspension fork and hub dynamo.  Both seemed to work fine without causing
problems for each other ...

<aol>, only mine is a Streetmachine recumbent, and my wife's is a 
Fiero recumbent. Neither have had any bother with the hubs or 
wiring up the fork legs.

<aol x2>

My wife's bike (upright) also has a suspension fork and hub dynamo and 
is also fine

I have such a bike. 

I found that I needed to use a two wire system for all the electrical 
connections as there seems to be a disconnect between the hub and the 
frame.

My Speedmachine has one.  Just leave a bit of slack in the cable to allow
for the fork movement, like one would for brake cables, computer wiring,
etc. etc.

If you're paranoid, you might want to use super-flexi wire.

Electronic test lead would work very well, if you
can find the length you want for a sensible price.

I did this on Michael's Giant Boulder with no ill effects, the only
tricky bit is ensuring that the cable can flex without fatiguing.  I
mounted the front light on the brake bridge so the current to that was
not going through a cable that flexes a lot.  You can get super-
flexible cable.  You also need to wire both halves as there is no
electrical connection between the fork and the frame (and actually I
recommend this anyway, I don't like running current through the
headset bearings).

Send me email if you want to bring it round.

Attaching the electrical cables alongside a brake (or gear) cable going 
in the the same direction helps prevent any sharp flexing bends when 
crossing a moving joint, whether it be suspension or steering.

Brake and gear cables are also a bit tougher than leccy wires - you can 
get way with some of the knocks with control cables.
There is also then possibility of scuffing of insulation which can lead 
to low resistance in the damp.
Some bikes seem to have cable paths thrown in as a last minute thought 
rather than anything practical.

Just like most cycle paths too then! :-)

Thanks everyone, especially Guy for your kind offer: I'll get the wheel 
built asap.
