    How's this for a possible solution to our bicycle energy needs. I'm thinking chain or belt drive with a system to engage/disengage at will.

    Maybe a sprocketed front wheel to drive the generator? Any ideas?


    A small, permanent magnet generator that is 7 1/4 inches long and has an outer diameter of 3 inches. The shaft is 15/32 of an inch, is 2 3/4 inches long and has a threaded end (5/16 inch - 18, 5/16 inches long). Capable of generating 15 to 20 amps at 30 to 40 volts at 6,000 to 9,000 RPM. Perfect for use in pedal powered projects, small wind systems and many other projects. The generator is durable and has been used in applications at our firm and for over 8 years. Uses high quality, heavy duty bronze sleeve bearings.

    I wouldn't tap the white wire for power due to possibility you short out the magneto. Plus, using it would require regapping the spark plug.

    Many folks want to power for long trips to recharge batteries, power headlamps, recharge cell phone/ipod/GPS, have campsite lighting (battery) that can be recharged etc..etc..

    Same type of topic came up in another thread, talking about the gas/electric hybrid a member here built.
