    UK police could get Ghostbusters-style backpack devices to halt ebike getaways

    Which coil or magnet is the built in safety system i wonder. Good luck trying to stop my bike to retro fit anything.. Is this just a re-hash of the dutch bluetooth mass shutdown capability to "stop bikes from entering/leaving an accident/crime scene" So some chap has a cosplay skin for his...
