• What we need is a Man of Science to work out the energy generated by a spirited descent of Ventoux by a laden tandem.

    Right then

    The major component of this would be kinetic energy (rather than the component of gravitational potential energy you are resisting by going down a slope), so lets estimate this.
    Assume m = 175kg (tandem, two riders, loaded)
    At thirty five miles an hour, v = 15m/s approx.
    Kinetic energy = 1/2 m * v squared
    = circa 19,700 joules (or Watt-seconds)

    If you wanted to stop all of this dead in ten seconds, you'd need to apply 1970 watts.
    Or five seconds, 3940 watts.

  • Assume m = 175kg (two riders)

    That sounds about right for my tandem. A loaded touring tandem could easily be 50kg over the bare rider mass without even considering camping.

  • Currently, we have a combined weight of 105 kg unladen but it's only going to increase as she gets older and I get fatter.
