    with a power meter.

    otherwise too many variables. Is it a flat road or up/downhill, tail wind, head or cross, weight of the rider etc.

    I'd say you can pick up a 2nd hand Powertap from A$400 (UK#200) right up to several thousands of dollars/pounds for the most expensive models.

    No, I don't sell power meters.

    I did send a PM response. Did it not come through?

    2nd hand items can be found in the classifieds section of forums like this or more likely on other cycling related forums that specialise in training with power, and of course on eBay.

    Ric Stern does sell new power meters so you could drop him a line via www.cyclecoach.com. He is moving house right now and is likely to be off line for a few days. The product range can be seen via the web site (which has recently been upgraded by the way).

    My intro information is also available on the same site.

    There are other sellers of power meters as well. A google of retailers of the main brands previosuly listed will show you a range of suppliers.

    You can also hire Powertaps for around £40/month - well worth it to see how you get on with one before splurging loads of dosh.

    Yes, that's a good idea too but not sure if Bob hires outside the UK ?

    For those outside UK/Europe, usually the cheapest location to buy from is the USA.

    Hello anyone...

    I have an idea in creating a power meter by myself...
    It's attached in my trainer, connected to generator that will be measured by Ampere and volt meter...it will be connected to the DA converter...and the output will be read in my Laptop...

    Anyone has an experience with it ?

    Hi there.

    The tricky bit might be calibrating the losses in the system across the range of input speeds to your generator...

    Cheers, Andy
  • I have a question,
    Should I use generator, so I will generate the power ?

    Or I use motor, that it will train my cadence pace ??
    I hope you all get what I mean...

    surely using a motor will only train your cadance if your on fixed, otherwise you'll just coast... I'd say get a fixie for cadance training and run a generator off your turbo...

    So if I want to increase VO2 Max and Power beter train with higher resistance and heavier flywheel....any idea how to put more weight in my rear wheel ?

    I will photo my modified trainer and the resistance that I have made....

  • Here's the trainer that I was talking about...I was thinking a motor on it to train my pace...

    The motor will be attached in the core for more resistance...
