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 ... -- These opinions might not even be mine ... Let alone connected with my employer ...

<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.

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.

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. -- Guy

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.

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