The security thing is right up my alley.
To start off, get a CCTV sign straight away and mount it in the wall right behind the bike so they can see it.
PIR controlled security light next, mount it no higher than 7' off the ground, and shine it onto the approach route leading up to the bike.
Finally, get CCTV installed, infra red preferably, and make it obvious. Yet again, don't mount it too high off the ground. Scrotes wear caps and hoods, these cast shadows over their faces. The higher up the light/camera, the more shadow you cast.
You can do the usual of ground anchor, and friggin huge chain, also gates on your property with a lock of some sort. And cover the bike up!
The last thing is that bikers hate gravel drives, burglars hate them more! They often walk away from gravel paths, too noisy.
I hope the fookers don't comeback and have another go. Keep that bike of yours safe dude!
for every up there's a down. let's say that i'm a bike thief, i'll take these points in order:
a sign - hmmm, am i scared?
security light - after every cat, fox, hedgehog and squirrel (not to mention other building dwellers) have set this off a few times and the bike owner hasn't come rushing out then a light makes it easy for me to see what i'm doing if it's dark - thank you!
cctv - pah. balaclava and overalls.
ground anchor and chain - now there's a better deterrent. nothing that a decent bar and cutting tool won't see to but then i'm thinking that the owner will be coming if i start making noise.
gravel drive - no thanks. noise and a fair chance of toppling over once i'm on the bike and trying to get away.
so what else?
decent alarm and immobiliser? no thanks again. more noise once i disturb it and i have to know how to get around it if i'm to ride the bike away.
a decent sturdy shed or garage to house the bike? no thanks. i have to gain entry to this first - breaking and entering to be taken into consideration.
any vehicle's weakest security points are their users. we all want to be able to jump on/in and be away - hence a single fob/key combination. so really i'm better off entering the adjacent property and taking a look around for said keys! it just goes on and on.
as an aside on ground anchors - i've always considered a large eye on a long thread to be more secure than a bolt down plate type anchor. in order to unscrew the eye it turns and tightens any chain that goes through it. plate type anchors can be chiselled up.
in this case solo i'm guessing that these thieves/vandals won't return. anyone that bends your handlebar trying to break the steering lock doesn't have too much experience of taking a bike. i think it was a one off attempt, probably drink fuelled.
given the above if someone wants your (any) bike they'll have it. probably the easiest theft these days is to wait for the owner to come to a vehicle, threaten or attack the owner and take said vehicle. i'm quite a big bloke and can handle myself but i'm also self employed - so would rather a couple of blokes had my bike than defend it and take the injuries and time off work....
