Thanks Gyula, I think I'll try a couple of different rotors of differing masses.

I've already established it can carry a load without drawing any more current so it will be interesting to see how much drag the dynamo has. I may have to work out how I can get the motor up to high RPMs first before engaging the rotor. I need a clutch I think :)

The fastest I've ever been on my mountain bike is 50kmh or 830m/minute. My wheel circumference is 205cm so my wheel would have to be doing around 4000rpm?

not 4000.
400 rpm (830/2.05).

Doh I was doing 200mm - how embarrassing! :)  That is low rpm. Looking forward to getting my dynamo. Edit: Maths & South Australian Shiraz don't mix too well.

Still waiting for my dynamo but just saw this on the Minatow list. http://www.dailymotion.com/video/xd0hk3_moteur-energie-libre-6000-tr-min_news any thoughts? My guess it would have trouble carrying a load but 6000rpm without electrical input...... errrm
