+1 on the Saris Bones
Bought one from Halfords to take kids Isla bikes down to Spain on holiday.
Missed ferry to Santander (long story), so ended driving from Caen (northern France) to Montpellier and then on down Barcelona, Valencia and eventually to Cartagena. 1,200 miles in two days. No issues at all.
If you get it from Halfords in store - make sure they price match the website, as it was about 10 quid more expensive than online.
