After having watched someone try to steal my bike when I had a cheap Tesco combination lock on it made me think that really I ought to get a better quality lock instead. This one fits the bill with lights which show your combination when its dark and it is long enough to tie up to 3 bikes when using a suitable bike rack. I purchased two of these and so far would highly recommend.
Very secure and quite long, you can tie it anywhere and not worry about it. The combination system is easy to use and the light feature is helpful at night. Above all, it's not expensive compared to others I've seen.
This combination lock has a great design that includes strength, and ease of use for the cyclist in a hurry! The lit tumblers are simple, and usable whatever the time of day. Buy with confidence!!!!!
