Is there a way to electrically immobilise my bike when I'm not near/on it? I'm thinking some sort of proximity sensor, or hidden kill switch. Would be good if the display was coded and removable, but I don't think the Purions are?
you cant remove the purion display as it has a fixed cable tho you could remove the batt in the back but you would have to unscrew it every time from the handle bars.
easy option is just to remove the batt and or fit a alarm.
