some interesting ideas on here: there seems to be 2 types on non key thefts scenario 1) moped gang wheeling away scenario 2) lift and throw into a van scenario 1) steering locks get broken, locks get removed (battery angle grinder), bike is pushed away (1 c**t on the bike, 1 c**t on the moped with his foot on stolen bike to push it away) scenario 2) assuming lock is attached to something immovable they cut through lock, pick up bike and throw bike in van we have trackers, they are pretty effective, and big arse locks which are difficult to carry about (judging by the videos this only slows them down anyway). scenario 1) the idea of the removable clutch lever was a good one, having changed a clutch lever in less than 5 minutes a quick release device similar to a bicycle wheel would work, providing you left it in gear - could be easy to get round if gang had a quick release clutch lever of course you would hope they wouldn't carry or be able to carry every lever known to man so it would make it more difficult.. locking the brakes is another option but have others have said brake lines can be cut and these are likely to get stripped down so they aren't bothered about causing a bit of damage. use the battery to electrically charge the bike / turn the grips into cattle prods so you fry the bast*rds when they try to take it - NB. must remember to switch it off before climbing on yourself.. 2) buy something the bast*rds can't lift unfortunately the only options available are make yours look less desirable than the bikes near by in the hope they try to steal those instead
