Bike rack on a Mk1 cab?

anyone put a bike rack on the back of a cab before?

i assume someone makes them that fit to the bumper but haven't found it yet. all the temporary racks i find attach to the rear roof or window in some way, so are no use.   any brands/shops/ideas welcome.

help me drive in the sunshine to the mountains with the roof down and cycle my bike.

   

The single bike, cheap one from Halfords will work, i used to use one for my kite-buggy. BUT, it was unstable… The plastic clips attach onto your boot lid, which is close to where your rack will be. The buggy weighs about 20kgs, it might be ok with an mtb.
  The buggy fell off 3 times. :roll: Its a ?1000 fine if it falls off.
Ive now got a 306 for the buggy! its half full of sand, but there's no way im putting the bug on my GTI!

best of luck!
