Hi All,
Can anyone please recommend a cycle rack that will carry 4 bikes. The rack will be for short journeys only and the bikes don't need to be left unattended on the rack. I don't want to carry the bikes on the roof and I don't have a tow bar so by elimination I guess that leaves just the rear strap-on type. My car is an estate and my wife's is a hatch back (both Vectras), however the estate car has a rear spoiler at the top of the rear door (will that be a problem for the straps?).
Many thanks in advance,
Shaun.
