Thanks for stopping by! We are excited to bring you HaamLock, the smarter bike lock. 

So, what is HaamLock exactly? 

HaamLock is a high tech bike lock 

  • Lock and unlock it with your cell phone 

  • Use it to find the safest spot to park your bike* 

  • Find your bike on a map if you forget where you left it 

  • Protect your bike with HaamLock’s sturdier mechanical design 

  • Easily notify your friends in the unfortunate event that your bike is stolen

  • Charge it via a mini USB port 

 * Currently only available in Chicago, we will add additional city bike theft data if we receive 50 backers or more in a given region 

And what do we need these funds for? 

Have you ever had to break into your own bike lock because you broke or lost your keys? Our dream is to take this product from prototype to the streets of  your city and allow cyclists all across the world to ditch their keys and embrace a simpler way to secure their bicycles. We have successfully built two working prototypes of our lock. We have also completed our iPhone app.

Our next step is to produce a first batch of the locks. This is where you come in, we need your help to: 

  • Take the product from prototype to street ready 

  • Cover material costs such as metal and electronic components 

  • Set up production and assembly at a local manufacturer 

  • Cover shipping and handling costs

Who are we? 

We are a group of Northwestern students who are tired of seeing bikes disappear from campus and watching bike owners saw off rusty old locks when they lose their keys. When we (Joppe Bijlsma, A.K. Singh, and Zeina Abou-Said) first arrived at the Kellogg School of Management last summer we became friends with Fabio, an international student from Brazil. He had just bought a brand new bike, but it was stolen within just a few hours of parking his bike on campus. Over a million bicycles like Fabio’s are stolen every year, yet bike locks have not changed much since their inception over 40 years ago. We thought there must be something we could do to solve this problem. We pitched the concept of HaamLock in a startup competition on campus in October and ranked among the top teams. Through the competition we were granted access into Northwestern’s innovative NUvention Web program, a class in which students build and launch a business or product. That’s where we met Shaker, Mengyuan and Patrick - the rest of the HaamLock team. We then pitched in Kellogg’s 2013 Shark Tank competition and once again wowed the audience with our product. To learn more about the team check us out at www.haamlock.com




What makes it sturdier than a traditional U-Lock?

HaamLock has improved on the standard U-lock design, adding a second locking pin, effectively doubling the amount of time it takes a thief to cut through your lock. 

How long does a charge last?

Under normal usage the battery will last over a month. The battery can be charged in 3-4 hours after it has been fully depleted. Since, the lock uses a mini-USB port to charge, any external USB power source can be used to power the lock if the battery runs out 

What kind of security features are you using to ensure it’s not hacked?

HaamLock uses the enhanced security provided by the Bluetooth LE standard. Additionally, we use industry standard encryption to make it next to impossible for the lock to be hacked.

In the rare instance that the lock does get hacked, the firmware on the lock can be updated to close any security holes.  

What if your phone battery dies?

You can always pair your lock with another iPhone using your unique pincode.
