Subtle. Simple. Secure.

A bike I rented in Hampi had a very neat lock on it. It was so subtle that I didn’t notice it at first and actually went back to the shop to ask for a lock, at which point the shop keeper showed this neat device to me.

A simple metal bracelet which wraps around the rear wheel. When the metal lever is pushed down, a metal bar slides through the spokes of the tire, so the tire can no longer rotate.

A simple, elegant bike lock.  Surely it most be cheap to make. Ideal for a bike rental agency, where the theft you’re looking to prevent comes in the form of opportunists waiting outside popular tourists sites.

Sure, it does not secure the entire bike and a thief could steal then entire bike or use tools to disassemble parts, but since those are less opportunistic thefts and more preplanned, I think this lock is well suited for the work it is assigned.

With a simple turn of the key, the tire is released, and I pedal on.


  1. There’s a reason why it’s cheap, it’s very easy to break try smashing it with a stone for example. I used to have it on my bike when I was in school.

    And do you also have experience smashing the lock with a stone?

    I feel like stronger materials could make it less “stone-smash” susceptible. Alternatively you could design the lock so that if it is smashed it stays closed or punctures the tire, so the bike wouldn’t be worth stealing.

    That said, I don’t think this is an ironclad solution, but an innovative approach for sure.
