Peter,
have a way round pedalling all the way from Lausanne carrying 3 batteries.
We drive to Lausanne in my LPG fuelled van, buy a couple of bikes.
Stop a mile before the French border, get the bikes out pedal across the border, park up the bikes, I walk back for the van, drive the van into France load the bikes again and head for Calais, unload the bikes and put them on the ferry, (3rd person required for this stage 2 to handle the bikes, 1 to drive the van), go through customs at Dover, load bikes back in van and drive 10 miles from home, take bikes out of van, cycle home and impress the neighbours with the fact that you have just ridden all the way from Switzerland. They will then all want bikes, back to Switzerland and do it all over again.
Or is that called smuggling?
Up for it Peter
John
P.S. (if Customs & Excise happen to read, it was all Peters idea and John is not my real name!)
