Power and Cyclist Demographics

[nuliajuk]

It seems to be a self-limiting sort of survey, as most people who own power meters are serious racers, not recreational cyclists.

I'm buying a hub dynamo on eBay and having it built into a wheel. I wonder if a dynamo headlight could have some sort of meter built into it that would give a clue to power? Of course, a long downhill stretch could throw the numbers off, but it might work.

I would guess it's possible - I have a computrainer - which is basically a trainer that is a dynamo with a meter… My husband and I have sometimes had the opposite question, it doesn't actually power anything so we've wondered if we could rig it up to say charge my iPad…

yes it can be done. you would need to disconnect the "meter" from the generator/dynamo and connect the generator/dynamo into a voltage regulator. Devices being recharged by USB cable all takes 5.0V.

The pedalpowergenerator.com people are charging an arm and a leg. $150 for a 12V charge controller Portable devices recharged through the USB cable all take 5.0V. It's part of USB standard whether its USB1.0, 2.0 or 3.0 so you would still need additional electronics.

hmmm another potential product for me.

lol… I knew you could get a pedal power generator. We've just joked about the "waste" of using the trainer…. but if I'd have to disconnect the meter then it wouldn't be of much use

It is a slippery slope that powermeter thing. Next thing you know, you need to justify your purchase by getting some serious training.
