Lock Mass Index (LMI)

We’ve set out to give you the lightest high security flexible bike lock we could and we’ve compared Litelok with the other 106 locks on the Sold Secure website (Gold category).

As most locks are different lengths, we thought that for the same (high) security rating we could create a new index for bike locks – we call it the Lock Mass Index (LMI) and we take the weight of the lock in kilograms and divide it by the length (or circumference) in metres. The result is then a rating where a lower LMI is good if you are interested in a lightweight lock, for the same (Gold) rating.

Here are the results for the best selling locks:
