We compared Litelok with 106 other Sold Secure Gold bike locks. As most locks have different lengths, we have created a new metric called the Lock Mass Index (LMI), which takes into account both the weight and length of a lock, giving you a better figure when comparing bike locks. The LMI is simply the weight of the lock in kilograms divided by the length (or circumference) in metres. The lower the LMI number the better, for a given security rating such as Sold Secure Gold.
Here are the LMI numbers for a selection of best-selling Sold Secure Gold bike locks, demonstrating which is the best bike lock in terms of LMI (hint: it’s Litelok).
