developed by three chilean engineering students; juan josé monsalve, andrés roi and cristóbal cabello, the ‘yerka‘ project maintains the design of an urban bike yet incorporates a closing frame device to improve security. to thieves, every lock can be broken whilst leaving the bicycle intact, the creators have a strong clamp out of the velocipede’s  frame. this means that the only way to steal it is to break the lock and thus the two-wheeler completely. no more will you have to carry around a padlock as the yerka tech uses the bike’s body as the securing measure, taking less than 20 seconds to set-up.

the large lock can fix to large objects as well as bike racks




‘we are 3 engineering students, that being victims of the theft of our bicycles, decided to develop a technology that prevents this.’ said juan, andres and cristobal, ‘today we continue to develop this project, which we believe will be a huge help for all of you, bike enthusiasts.’ as the ‘yerka’ project has done, using the frame as a locking mechanism makes for a safer and more secure cycling experience.

  • very thoughtful… but i’ve seen the thieves steal anything that’s on the bicycle. Whatever can be removed, they will remove. The best i’ve seen is the wheel is still locked to the poll but the rest was gone.

    grgeblck says:
  • just buy a freaking lock!

    Jordan says:
  • I do not know about the bicycle, but this definitely will protect the tree, fence, pole, or whatever from …stealling

    Angel says:
  • I believe the word should be “DETERS” thieves.

    Lightmaker says:
  • the frame will be less sturdy and i don t see why this integrated lock should be better than an actual lock

    tommaso says:
  • Good idea, but not convinced it’s 100% thief-proof. says:
  • Authorities generally don’t like street furniture being used to secure bicycles.

    Kees says:
  • I will cut the tree/fence/pole to steal such a bike! Nice thought though.

    Abhishek Khanna says:
  • If I see it correctly, the vandal/thief breaks the lock and no-one gets to ride the bike. I guess it has the potential to put off the thief that wants a rideable bike. ie the knowledgeable thief. Perhaps it doesn’t put off the vandal, but that might be OK. It definitely looks interesting….

    Bret says:
  • At least! the frame will be there when she gets back less parts.

    bzar says:
  • From the opinions here, might aswell not have a bycicle, since if you have it, you will get robbed. Hell, might aswell not won anything, like that there is nothing to be stolen. Jeez… I´ve seen some projects here in designboom that are complete crap and not even design getting great comments. This one is actually quite clever and it´s DESIGN and gets critics all over the place.

    what? says:
  • Hardcore thieves will cut the tree…much more easier and walk away with the bike

    teacup says:
  • hard to believe there was any thought behind this. anything but practical!

    Victor says:
  • They had to speed up the video, when unlocking the bike. It obviously takes to much time

    oliver says:
  • I live in the bronx, and I use a standard lock and have no problems!

    Robert says:
  • i wish they would add retractable cables to lock the wheels also. that would make it worthy, otherwise this design is kind of useless because you would need extra locks for the wheels (for anyone that lives in a big city).

    an urban cyclist says:
  • cut the seat post, take the bike, pick the lock with all the time you have, stick any cheap seat post back in.
    the top tube is the weak link once down tube section decoupled since no more main triangle. top tube then easily bent by stepping on it — a likely scenario with any practical joker.
