Falante 110db Anti-Theft Alarm Motorcycle Handlebar Lock Aluminum Alloy Brake Grip Lock Adjustable Bicycle Security Equipment

The pros: loud, solid chunk of metal, hold a tight grip, safer keys than those other simple round shaped ones. The cons: Heavy, I hate to carry this around in my backpack, it's nearly as heavy as my wheel chain which to me offers greater protection. I use this one only when I park it for extended times, but don't want to carry it around every day.

Everything is fine, thank you very much.

Awasome... Thank you very much seller

Guys, my order has arrived. I want to thank the seller for the delivery; it was really fast despite coming from outside Brazil. The delivery was very fast indeed. It's great that we are having such fast deliveries. I really want to thank the seller for the delivery. Anyone who wants to buy can go ahead and buy.

The alarm doesn’t work.

I think... a good lock. BUT... Do not buy if you use handguards because the handguards is in the way of the locking mecanism. My fault. I should have studied the photos more...
