I'd like an accurate, cheap, reliable powermeter that I can use to race and train, costing no more than £200, ANT+ compliant as well please. Oh, and light too.

What are you currently working on then?

You know how I meant it.
I want to lower the price of power meters to a level, what more people can afford. Not everybody of course, but more.

Thanks for Your response. The parameters You gave are pretty close to my concept about power meters. To do this in real life isn't that easy, but I will try if everything goes well.
I only have plans now (both mechanical and electrical). If I'm going to do a development, I want to do it right. So first I have to get information about what people need. After that I will check whether it can be achieved or not with an investment that I can have.
I really hope that the responses will show that I worth start the real development.

There are reasons other than corporate greed why power meters are expensive, the tech has a lot of development costs (and issues, just look at the pedal based systems, which are still in development hell), getting strain gauges into a package that is small, light, accurate and able to cope with the harsh environments we expect, isn't easy.

Price shouldn't (IMO) be a primary consideration, accuracy and longevity should be.

I would love to see a power meter for £200, but lets be realistic here.....

I exactly know how complicated it is to create such a thing. But my opinion is that it's possible for about £300 (that's my personal price target) with some limitations. We only have to figure out, which limitations should be made in order to keep the product meeting the buyers expectations.

Accuracy, longevity and durability, and work back from there.

Why not just design a heart rate monitor that extrapolates power from heart rate?

factor in distribution, warranty, service backup and support, marketing, legal, taxes, costs to transition from a working prototype to items manufactured and still reliable. and make some money :)

but go for it!

I'd love to be proven wrong, but I don't think it'd be possible to produce a reliable and functional power meter for £200 or even £300. It doesn't need to be that cheap anyway - if you could sell one for ~£500 that's lightweight, reliable, robust AND produces good data you'd be onto a winner.

Reliablility, accuracy, cost........if it can be done for under £500 I reckon you would have a winning solution there.

IF you could make one that was reliable etc etc and sell it for £300, why on earth would you? With no competition anywhere near that, you could still sell it at £350, or £400 or even £450.

So, is it hub-based or crank-based? Or pedal-based?
