Locking helmet with micro-metric buckle to bike

If you just need a locking cable you can find one low priced at Wall Mart in the bicycle section.

I use this with a 4'cable. Can lock helmet through the chin bar (or two helmets) plus can run cable through sleeve of your jacket to secure that as well. Fits well in either cubby or in the gas cap well.

My flip fits in my saddle bag also. But in case I'm already full I carry a cheap lock stored under my fuel lid to the side of the cap. Plenty of inexpensive choices 4 bucks and up. https://www.walmart.com/ip/WordLock-...stomer-reviews
