I would probably do something like:

# reset( $Bikes )
while( list( $BikeType, $Manufacturers ) = each( $bikes )) {
   echo "$BikeType<BR>\n";


#   reset( $Manufacturers );
   while( list( $Mfr, $Models ) = each( $Manufacturers )) {
      echo "&nbsp;&nbsp;$Mfr<BR>\n";

#      reset( $Models );
      while( list( $Model, $URL ) = each( $Models )) {
         echo "&nbsp;&nbsp;&nbsp;&nbsp;" .
               "<A href=\"$URL\">$Model</A><BR>\n";          }
      }
   }


This would give

Road
  Trek
    Trek  <-- is a link
  Schwinn
    Schwinn Fastback Pro  <-- is a link
  Moots
    VaMoots  <--  is a link
  Lemond
    Zurich  <--  is a link
    Chambery  <--  is a link
    BuenosAries  <-- is a link
    Tourmalet  <-- is a link
Dirt


If you realy want

  Trek
  Schwinn
  Moots
  Lemond
    Trek  <-- is a link
    Schwinn Fastback Pro  <-- is a link
    VaMoots  <--  is a link
    Zurich  <--  is a link
    Chambery  <--  is a link
    BuenosAries  <-- is a link
    Tourmalet  <-- is a link

You need to do the outer look twice, doing a reset() in it between them,
and doing the reset()s I have commented out in the example.  Be aware if
you go thru the array more than once in the program it will be needed.
