    Shimano coaster / cog question

    I am trying to lower the gear ratio on a new
    Schwinn-Pacific product that has what appears to be
    the generic, cheepo coaster brake.
    I would like to change the cog from an 18 to a 15(?) or lower.
    Can someone help with a resource for cogs or whatever is
    needed to do this ? Im exasperated because any combinaion of words
    I type into Google only gets me Shimano road bike 9-10sp cog sets, etc...

    Thanks in advance !!

    The smallest coaster brake cog I can get is a 16T from a bike supply wholesaler. These are for Shimano E110.
    Bikes use brakes to stop.

    If your bike has breaks, don't ride it.

    A lower gear ratio requires a larger cog on the rear.
    For example, 44/20 is lower than a 44/19.
    2.2:1 vs 2.32:1
