Whats the real difference between a £50 chain lock and a £150 U-lock, and can we honestly say that spending more money on a bike lock guarantees better security, or are we just falling victim to clever marketing and a false sense of security? With so many bike locks on the market claiming to be unbreakable or theft-proof, how do we separate fact from fiction and make an informed decision about what lock to use to protect our family bikes? Is it really just a matter of choosing the lock with the highest security rating, or are there other factors at play that we should be considering, such as the type of bike, the location where it will be locked, and the level of risk were willing to take? And what about the environmental impact of our lock choices - are we inadvertently contributing to a culture of disposability and waste by opting for cheaper, less durable locks that need to be replaced more frequently? Can we have a discussion about what constitutes good enough when it comes to bike security, and how we can balance our desire for security with our need for sustainability and value for money?
