My mum is getting pissed off with my bike being indoors and wants me to keep it in the shed, So i've been trying to think of way to make my bike as safe as possible. I thought that a ground anchor, Nice fat chain and some door and window alarms could help, Is there anyone that uses any of theses products or uses anything else to prevent there pride and joy being stolen? Window or Door alarm, 120DB alarm, With an entry/exit delay. Ground anchors, Supposedly have fixing bolts and security ball bearings which makes them drill-proof. No need for setting new concrete with the anchor neither. Nice fat chain, Maade as a motorcycle chain so should be nice and strong. These are three things i can think of that will really help to prevent my bike being stolen. Can other people state whether they keep there bike in a shed or garage and what methods they use to help prevent thieves from doing what theves do best. Cheers Alan.
