It’s also very noticeable and easy for someone to steal.
Your helmet is also open to the elements, although by being the right way up, at least it won’t collect rain like it does when on a helmet lock. Just remember to close the visor!
If you do store it on the seat, the most secure way so it won’t roll off is to have the visor facing the side with the sidestand.
Like the seat, it depends on the bike and is open to the same problems of security.
Hang it on the handlebars
The quickest and easiest place to hang a helmet is on the handlebars.
This can be secure, especially if you can get it over bar-end mirrors to stop it slipping off.
However, this can still be a precarious position where the helmet can easily fall if the bike is bumped.
It could also compresses the interior foam liner if you hang it with the helmet facing down. Compressing the liner can make your helmet fit more loosely and decreases its ability to protect your head in a crash.
However, it may be ok if your helmet allows you to rest it on the chin bar as in the photo above.
You can buy special helmet hooks or use a carabiner to hang it off the bars via the Double-D clasp (if it has one).
But again, you have the problem of the helmet filing with rain and dust and being stolen.
If you do hang your helmet on the bars, make sure it’s the right bar as this is safer than the left bar which slopes down when the bike is on its sidestand.
The same goes for hanging your helmet on the footpegs.
It may seem more “secure” because it is not in plain sight, but I saw a pedestrian walk past a bike and accidentally kick the helmet because it wasn’t easy to see.
The helmet, rolled about 50m down the road. A write-off!
If you do hang it off the footpegs, make sure it’s on the right side, opposite the side stand, as they can slide off the down side because of the bike’s lean.
Cables and alarms
If you choose to hang or store your helmet on your bike, it may pay to secure it with a wire locking cable.
Some are made of tough titanium and some even have alarms if moved.
