Never done it myself but wondered about it. If you have an electric hookup at the pitch the post might be substantial enough to lock the bikes to, but be careful you can't lift the lock right off the top. You may also need a special camping hookup with a round 3 pin adaptor. With the boom in ebikes, you'd think there's a market for campsites with secure bike storage and charging facilities.
You don't have to charge it where you lock it though, you can watch it while it's charging then lock it up somewhere else.
Probably worth phoning round a few sites and asking them
If you have 2 bikes then locking them to each other - facing different ways - at least makes it damn inconvenient to steal them
I think you can assume that it is unlikely that someone will just pick them up and put them in a van on a campsite but......
Also - and most importantly - if the batteries can be removed to charge then do so and charge them in the tent - so out of sight - an ebike with no battery is pretty useless as far as direct reselling is concerned!
you could also get one of the ground anchors that you can tie a dog's lead to - they just screw into the ground so can be unscrewed easily - but the average numpty that steals bikes isn;t going to know that (probably) and just making it that bit more inconvenient will help
Other thing is one of those motion sensitive alarms - never used one but on a campsite they could be useful
Lots of good ideas there, thanks. I hadn’t thought of the bikes facing different directions or the ground anchor.
Been thinking - or probably over thinking - and making one of them upside-down would make it that bit more difficult
basically you are trying to make the idiot think either
Nah - not worth the hassle
or
I take that one over there instead
Oh - and - if you get one of the personal alarms you can get where there is a base unit about the size of a packet of fags and a loop that comes from it - and when you pull the loop it comes away and the alarm goes off
Then you can put the base unit in a saddle bag and pul a tent peg through the loop so if someone takes it the then accidentally pull the loop away and it goes off
Got the idea from the shed when I moved in here - the "alarm" on it was a very simple personal attack alarm stuck to the shed roof and a nail on th edoor for the loop to go round
anyway - good luck
