I'll get the Pragmasis chain and padlock plus a disc lock, not alarmed, and bike cover. I also have a Kryptonite NY lock for my pushbike that's motorbike rated so will use that through a wheel. The best I can do at work is a lamppost (which I've read is better than street signs) as the work car park is easily accessible and there's nothing to chain it to. There are a couple of bikes already parked on the road with no security so mine should be a harder target. I've considered a used scooter so lower premiums, less nickable, but I don't know bikes or have a mate who does. The cheapest scooters in London shops is still over £1k, unless I go private, gumtree, etc. I'll read other posts for advice on buying 2nd hand and what shops are recommended. Thanks for the replies.
