Bike It Handlebar Helmet Lock
Customer Product Reviews
An easily fitted, useful accessory
For the odd occasion when I need to leave the helmet (or other oddment) attached securely to the bike, this is invaluable. I chose not to use the security screws supplied as I wanted to leave open the option to move it later; I'm sure it is still more than adequately secure though. I additionally fitted a plastic sleeve between the device and the bar to prevent damage to the chrome as one is not supplied.
