Agree with stumpy140. Waste of time trying to cover. I had a cover specially made for two bikes on a Thule towbar rack. Was made of the material used for boat covers. Two disadvantages, billowed like mad, the drag on the car noticeable, and the road grime in the wet just got up underneath. I never carry the bikes on towbar rack if rain threatens, grime gets into everything. Firmly believe our bikes would not have lasted 10 years and covered 17k miles each if I'd carried them on the car in the rain. When going on holiday, I hire a VW transporter van, keeps 'em dry and I get to drive a VW. GREAT. Would like one, but trouble getting it through committee. (Mrs O)
. Can't argue with the chairperson that you can get LOT of van hires for the costs of buying etc.... Even suggestions of "look how much shopping you can carry"... fails to sway the chairperson
