It's pretty good, but Gimmicky

For the money, this is reasonable quality. I think the loop length is a bit short, which limits it's use slightly, but if it works for your tiedown-point, shorter is better for security.There are a couple claims about the "dorable" rating on this lock, but the specifics aren't that impressive. I didn't destructively test this lock, but I can tell you based on my expertise as a Mechanical Engineer, that the Triangular bar does very little to help the strength of the lock (besides maybe wear down

Pros
  • Sports
Cons
  • May not be universally compatible with all bike accessories

I've had the lock mounted on 3 different bikes now, with varying tube sizes, and each time the mount came loose after 20 min of riding.It's also not quiet. The marketing claims "this bike lock won't make a peep while you ride" but it actually makes a lot of noise. Even if the mount was 100% secure it would make a lot of noise because there is some play in the mounting mechanism. Don't take this lock on your group rides, your friends will thank you.

Pros
  • This thing is SOLID! The key is precision and "sharp" take care and don't cut yourself!
Cons
  • Too heavy for some riders

The 8.5 inch U-lock from SeatyLock gets the job done when I need to secure my electric kick scooter while running errands or whatever. I have a Yadea KS5 scooter which is a little larger than Lime or Byrd scooters, and the 8.5 inch size fits just as long as I get the scooter right up next to whatever I'm securing it too. If I were to buy the lock again, I would definitely get the next size up, 11.5 inches to make it easier to find suitable places to secure my scooter to since the 8.5 in size is

Pros
  • ‎UM140BR
Cons
  • May require specific instructions for proper use and maintenance

Great lock! Most recommended!

I did heavy research on all types of locks and ultimately went with Seatylock.It is such a bad feeling like wondering if you're ever going to get home (or back to the office from a lunch errand) when you simply can't get the tumblers to open up and you're being super gentle to not bend or break the key off - something that will happen with competitive brands - but never with Seatylock!Lock mechanism is SUPER SMOOTH, feels very solid like you aren't at risk for ruining anything. Attaches very…

Pros
  • This is a study in strong lock I would definitely recommend it
Cons
  • Not weather-resistant

Really pretty 💕and strong lock !

All the reviews are correct! This lock is next level!I just got an expensive electrical bike and I have to park it in the garage. This lock definitely eases my paranoia🙏🏼 Especially when I ride it down to the beach in Venice where there is a lot of crime lately. No way it can be broken, It feels extremely well made , it’s very easy to unlock and lock. It does have some weight to it but nothing major or annoying. It also comes with a spare key . I also love it becaus it’s more of a hot pink…

  • Bike Locks
Cons

This is a serious lock

I recently had my Electric bike stole while I had it parked outside of our cabin on a trip. It totally ruined my trip and hurt that I lost an expensive EBike. I was using a thick cable lock that I used all the time on my daily errand rides. The difference was I left my bike this time for a longer period of time over night. SO for my new Ebike Ive upgraded my lock to a Seatylock. This lock is heavy steel and is said to be cut, drill, and weather resistant. The things I liked about it was it was…

Pros
  • ‎8.5 x 6.42 x 1.46 inches
Cons
  • May not be user-friendly for beginners

Peace of mind Security for my bike

Honestly, I have rarely needed a bike lock. But people who ride bikes or scooters a lot in a bigger city know the value of such security.This lock is built with amazing quality. The material, finish, keys everything is top notch. For a regular user like me there is no way to do a destruction testing but I have to go with the brands claim of it being Diamond Level security and double thickness with triangular crossbars. I just have faith that everything works as it is advertised. But most…

Pros
  • RELIABLE HIGH PERFORMANCE PROTECTION - SeatyLock Pro Break Resistant Thief Deterrent. Compact & Easy Carry Bike Accessory. Rust Prevention Coating & Components for Dependable & Quality Safety
Cons
  • May not be efficiently secured to bike locks in all scenarios

Need a heavy duty bike lock?

The Good:-Heavy duty-Thick-Easy to use-Long U bar-Solid constructionThe Bad:-HeavyThe Bottom Line:I just tried this Seatylock and wow this thing is hefty. I’m pretty sure no one is getting through this thing. It is easy to use and has a long U bar so you can lock your bike to the post easily. It comes with a key lock so no combo to remember. The only downside is this heavy duty ness comes at the price of weight. This lock is not light. Overall, I would still recommend this Seatylock if you’re…

Pros
  • Cycling
Cons
  • May not provide foolproof protection against theft

Great value on my review.

Looked at many "D" locks, good price for sold secure lock. I don't plan leaving my bike for more than a couple of hours at a time, just to the grocery store and breakfast/lunch.

Pros
  • Anti-theft
Cons
  • May be subject to picking or hacking attempts

Strong Deterrent - my new review

This SeatyLock Pure Bike U Lock - Patented Heavy Duty Anti Theft Diamond Security Bicycle Lock - Super Wide has been a revelation for me after struggling to find a quality lock that will fit on my dual motor electric scooter.My first impression of this was of what a nice touch by the manufacturer to put a rubberized coating on the lock it feels excellent and is also useful to prevent banging up your ride.The locking mechanism is solid so far, I haven't had any issues with sticking or it not…

Pros
  • PATENT ULTRA STRENGTH HEAVY DUTY ANTI THEFT TECHNOLOGY - Anti Cut Durable Waterproof Weatherproof Bicycle Protector with Antitheft Triangle Shaped Crossbars. Strongly Tested Guard System Stops Thieves & Attacks

Pros

Cons
  • May not be universally compatible with all bike seats

Pros
  • Nice quality and size.
Cons
  • May not be compatible with some bike carriers

Amazing product! - my new review

Amazing product! I love that it's lightweightMy Mason U lock weighs just 2.2 pounds and is Diamond certified. To my knowledge, it is the only product at this weight that reached Diamond, making it an excellent choice for my bike.

Pros
  • Accessories
Cons
  • May not be eligible for insurance reimbursement in case of theft

Pretty great lock! in my review

I’ve used kryptonite locks for a long time. What I like about this lock is that it weighs a little less, you can lock it from either direction, and the lock mechanism itself feels a lot smoother than ones I’ve used in the past.

Pros
  • Sturdy and easy to use
Cons
  • May scratch the bike frame due to its weight and size

Perfect for big bikes.

Heavy duty!Such high quality.Very happy with this.Don’t hesitate!Comes with 3 set of keys and 2 years warranty.You will need to register to get the warranty.

Pros
  • Waterproof
Cons
  • May not fully secure both the frame and wheels of the bike

Pros
  • UNIQUE AUTOMATIC KEYHOLE SHUTTER - Super Specialized Dust Dirt Rain & Weather Proof Gear for e-Bikes Roadbikes Electric Bikes Scooters & Motorcycles. Mounting Bracket for Frame Sold Separately
Cons
  • May be prone to rust or corrosion over time

Clamp can not hold the lock

The lock itself is very solid. The issue is with the clamp. There is no way to install the clamp and have it hold the lock during a ride. A lock that weighs 4 lbs can not be held by a clamp with a strap. My lock bounced around and now my bike is scratched.

Pros
  • ‎Black Diamond
Cons
  • May not be universally compatible with all bike handlebars

Amazing Lock! good for me

The magnetic mechanism of this U-lock is so so great! don't know how no one thought about it before! The strength and sturdiness of this lock is a huge bonus for me as I bike everywhere and need a good lock to keep it safe. If you need a great bike lock, do yourself a favor, and buy this amazing U-lock!

Pros
  • Like the weight but it will be restrictive because of the size.
Cons
  • Expensive compared to other bike locks in the market
