    Found these at a yard sale cheap.


    I got them both working for cheap and they are a blast to ride.

    They say Lee Iacocca on them and he was in charge of the company that made them until they went out of business in 2004.

    I think it had something to do with this.

    They have Heinzmann hub motors on them.


    36V NiMH battery packs.

    One pack was apart and someone had taken 2 batteries out and they measured 0 volts.

    I soldered them back in and plugged in the charger.

    The charger has a charge LED indicator and it was flashing and no charge current.

    The other battery pack was together but it would not charge either.

    I had got 2 very nice chargers in the deal and they both had blinking LEDs and no charge.

    Going to the packs is a 4 pin connector from the charger.

    Only 3 are used. DC+ , ground, temp sensor.

    On both packs the temp sensor was bad and prevented the batteries from charging.

    I connected a 10k ohm resistor from the sensor pin connector to the negative or ground pin.

    The charger charges them at 1.6A then goes to a 60 ma trickle charge

    They both work and will power the bike for 10 miles +.

    I did not expect those old batteries to work but they do !

    Looks like you have all the body work on them too. Quite a find.

    Yeah, I thought it would rattle but it doesn't.

    I am mounting a milk crate on the back of mine.

    The other one belongs to my wife. She loves it.

    Every woman I have shown it to asked to buy it ! :cool:
