An American brand with more than 50 years of history in the design and manufacture of bicycle locks. You can easily recognize the products of this brand because they have kept the almost identical shape of the lock in the form of the letter “U” since the beginning of the company's existence. The company is known for testing its locks directly “on the go” by leaving a locked bicycle in the rough streets of New York, while watching how long the lock resists thieves.
