    What is the cheapest electric motor I can practically use on a 27 inch bicycle friction drive? Also I intend one speed on the motor. This bicycle has thin low friction wheels.

    Chain drive may be best with an electric motor...

    A good amount of power is lost through the friction process, and considering battery life, you want as much power used as possible with an electric motor!

    On Ebay, you can find 250 watt motors from scooters for maybe $30 to $40 or so, higher watts equals higher price

    What is your idea for a battery and controller?

    It depends on your level of mechanical skill. If you have little experience, get a low wattage hub motor kit (250w or so).
    If you are more experienced, you can get a cheap 500w brushed motor and fab the mounts and chain drive pretty cheap.

    2 12 volt new lawnmower regular batterys available. No speed control,the bike has optimum high pressure raceing tires so i'm trying for a one speed rev up-then- lift drive and roll.The batterys are heavy so I maytry to mount them low.
