    Dynamo on rear wheel?

    Hi, all. I'm sorry if this has already been asked but is it possible to have a dynamo hub put onto my rear wheel? I'd like to do this so that even when I'm not going anywhere I can ostensibly use my bike a generator. Can't hurt to have it as an option... if it's an option. Any ideas?

    I think your only real option is a sidewall generator or a bottom bracket generator. I can't imagine how this 3 watts or so would be useful on the trainer in the basement, though.

    If you're going to want to generate stationary power, drive a generator directly from the trainer.
    Here's instructions on re-purposing a washing machine motor for the task:

    You'll get much greater energy returns out of it than a BB/Roller Dynamo.

    Shimano had a combination Dyno-hub cassette, But I have no idea where you get them,

    I imagined the primary application, Tadpole Recumbent trikes ,


    Add: its the FH C 811 in Nexave series

    so perhaps Greenspeed in Australia* has a clue.

    *They manufacture that style of recumbents..

    I don't want to produce power in my basement and yes only ostensibly use it as a stationary generator as I don't know that I'll ever need to use it while stationary. I'm turning my fargo into a self contained survival vehicle and the ability, IF I ever need it, charge my phone/laptop/whatever without leaving camp would be nice. Thanks Fietsbob, I'll look into you leads.

    I almost got in on the kickstarter campaign for this, but funds were too tight at the time. It is not quite out yet, I believe april is the eta on shipping.

    Well, there's the add-on SunUp Eco unit. Google for more info.

    There's also the vintage Sturmey-Archer gear hub dynamos, but I doubt that's quite the thing you had in mind.
