New in at Urbano Rider London.  The OJ Helmo bar end helmet lock allows you to lock your helmet and leave it. This Aluminum helmet lock replaces your bar ends (or just cut the rubber seals of your grips) allowing you to securely lock your helmet to your bike or scooter whilst you're out. This solves the issue of having to carry your helmet around with you. It fits bars with a diameter of 13mm - 22mm and comes with 2 different size tapered metal pieces which you secure to your helmet.
