a nice heavy-duty lock with easy to access dial sliders, meaning once you set your combination lock code, you can take this anywhere without a key. It’s thick metal and just like the old-school ones you remember, but can be used with or without a key if you so desire.It even has the ability to recall your combination if you forget it. And yes, you can change the combination at any time by resetting it. It also makes a handy weapon if you find yourself on your bike in a toublesome scenario haha. So this does just about everything you could possibly want a lock to do.

Wow...this is a super heavy duty bike lock with a combo, and a key. very thick and the lock on it looks pretty secure. Won't be able to cut this thing unless you have alot of time. The locking mechanism seems very stout, and I don't think that it will be a weak point. This is an amazing lock for the money to protect your investment.

This is a very nice lock. Very heavy duty/sturdy, easy to open and reset/recover code. Comes with keys and strap to connect to bike.

PRODUCT DESCRIPTION – Bike Locks Heavy Duty Anti Theft,Combo Bike U Lock with 2 Keys,18mm Shackle,4-Digit Resettable Combination Bicycle Lock with Sturdy Mounting Bracket for EBike Electric Scooter MotorcyclePERFORMANCE – This lock is incredible. The sight alone of it, is enough, (if I were a thief) to say stay away! If you want security plus, look no further. I hated marring this lock but my duty is review so I blew the dust off the metal grinder and attempted to cut the lock within seconds as I had done with many others. A major shower of sparks and after the smoke clear there was barely a scratch on this amazing lock. In brief, if a thief wants whatever this lock is put on, they must want it bad because it is going to be a long time before the lock will open! The lock has combination, lock with key giving you options to open. Top product, designed with craftsmanship in min. Pleasure to review. I am recommending to all my biker nut friends.UNBIASED - Amazon Vine reviewers are not paid for reviews, be it positive or negative. I will never recommend a product I would not buy myself. I treat ALL vendors with respect and fairness but my duty is to You, the Amazon customer. I am an Amazon customer too. I have every reason to be sincere in my reviews. If it is junk or treasure my reviews will reflect the products, I give my word of honor. I don’t want any reviews of mine to read like an ad but anyone who has written reviews knows, it is hard to not get sucked into writing in that style, if it is a great product and most are, then we are so enthused about the products and want to scream it to everyone, “Hey, this is a great product”. So in my view, that is why some reviews may sound like ads.I want to say, I encourage you as an interested customer, to ask me questions about the product and I will do my very best to answer each and every one of you. Amazon reviewers can write our views anyway we feel about any product; all we wish to do is help.A reviewer on a social platform often states, “He does not trust Amazon Reviews”. The gentleman is a great reviewer and makes very high quality content, however in this case I disagree strongly. Amazon reviews are dependable and useful. However, use common sense the lower the number of reviews the less accurate the score is. Products that are “Amazon Choice” have always been a winning selection for me. The Amazon review scoring system, lets you know what customers and reviewers like and dislike about the product you are considering purchasing.I cannot state this enough but Amazon Vine reviewers have no reason or encouragement to favor or disfavor any product. Reviews are not edited by Amazon, unless they violate community policy, for example profanity etc., Amazon does not edit reviewers. The comment about Amazon reviews being questionable is somewhat debatable. I assume the comment made by the non-Amazon reviewer is referring to Amazon Vine reviews. I can’t speak for no one but myself, but if the day would ever come that I thought I was obligated to writing ads, I would move on. Amazon knows the value of customer satisfaction and wants to weed out any products that do not live up to advertising claims. Again if you have a question, please let me help.

I have or my kids have lost almost every key for every lock we have at one time or another. This does solve that problem and it also very secure for a bike or a scooter. I have purchased more of these so that we dont have the key issue any more.

I just got a bike so I needed a good lock. This lock is perfect. It is sturdy and easy to use. I can quickly lock or unlock my bike. It is large but I have a basket on my bike where I can carry it. I feel safe keeping my bike locked up in public.

This lock is easy to handle. I love that I can either do a pin or use the key. It's not too heavy, but it does have some weight to it. No one is cutting through this lock. It is super strong and solid. The build quality is amazing and it locks strong the first time. I absolutely love this lock. I would recommend it to anyone

Excellent durable thick bike lock with combo and keys. I like that it has the combination number lock and keys. I also believe this lock can be used for more than just bikes or scooters. I think this lock can also work well on a fence door handles if need be. It can be used in various ways I believe. It’s super thick and durable so it’s going to hold up well through all climates too.
