i dont have to worry about this problem of people following me or even nicking my bike as i have armed guards 😀 (at my baracks)
when i used to live with my dad in the london suberbs the only bike i had nicked from my hous was my drm rythm but it was my own fault for leaving it out side unlocked!!
i have heard of people being followed home from a ride and once the thiefs hear the boiler kick in (hot water for a shower/bath after a ride) they hoof in your door and nick you bike!!
