The close up
Due to its intuitive patented design, its lower arm acts like a leaf spring allowing Helmetor® to hold the helmet using a single air vent between (this may vary depending on helmet type) 30mm to 65mm long.
It's a one handed operation!
Put the 'foot' of the Helmetor® into the vent first and then just pull the helmet up and over the top arm. It's that simple!
Yip, you can put a lock through the 'eye' which will offer some protection from the 'casual thief'. Remember to use a lock BIGGER than the vent!
