This bike lock is really easy to attach to the bike. The length is long enough to lock my wife and I’s bikes together. Comes with free bracket & fitting tool. The weight for this isn’t too heavy, really portable. I highly recommend this for people with bikes! Great product! It arrived as how I expected it to be! Kudos to the seller for a job well done! I’d really recommend it to my family & friends! I obtained this item at a discounted rate in exchange for a review. Regardless the opinions found herein are based on my experiences with this merchandise.
