The safest and easy to handle helmet anti-theft system. Thanks to an additional, spring supported locking bar it's absolutely impossible to open the slings without pulling up the seat. That makes our anti-theft system completely different from many other models. The carefully covered security rope takes two helmets at the same time and, when is not needed, can be simply stowed in the suspension unit. An enormously helpful product. Once you own it, you wouldn't miss it anymore..
