This is a convenient device for holding a helmet. It's a helmet holder that can be retrofitted to motorcycles and scooters that don't have a helmet lock. It's ideal for preventing helmet theft. It can be installed anywhere with a 22mm diameter pipe, not just the handlebars. The necessary hex wrench and screws are also included. If you are concerned about scratching the pipe, please insert a cushioning material such as cloth or rubber into the fixing part before installing. It can be installed on bicycles as well as motorcycles. Furthermore, a spare key is also included for peace of mind. Installation Instructions Pass the washer through the screw.
