ICOCOPRO Anti Theft Heavy Duty Bicycle U Lock with 3 Keys, 18.76mm, Black, 5.32 in Width Inside Dimension

Sturdy, big, easy to use. Thumbs up

Just what I was looking for. Fits perfectly for the BACK TIRE. This is the only one I have seen on the market. More colors would b cool? Love this one !

Love this lock. Use it for my gas scooter/moped. Locks very easily and fits onto my tire flawlessly.

I used the lock to lock my cargo basket to the cross bars on my suv. Tired the lock to the basket to keep it from hitting the top of the car. Works great.

It is really nice not so long but you can manage with a standard bike rack or fence maybe not a thicker pole or 2 bikes together. Would also been great to have a bike adjunction to keep it with me securely while riding my bike. Good product overall worth the price and purchase.

Good

I'm a contractor and have had several smaller ladders stolen off the ladder rack on my truck. I bought these to lock the ladders and it's working great. They're really thick metal, so would take some real work to cut through, especially while balancing on the rear bumper of a truck. The U-shape construction is wide enough to wrap around the thickness of the 1" aluminum rack and the ladder tread. I especially like the little button that covers the key entry so as to prevent rust and corrosion of the lock. So far, so good!

Good secondary level of protection for your e-bike

Buen diseño y construcción. Muy conveniente con las 3 llaves. Buena calidad en general. Leí en reseñas anteriores que se traba al ingresar la llave, a mí no me ha pasado pero sugiero que le pongan unas gotas de aceite o grasa automotriz y seguramente se acaba el problema, eso pasa con cualquier candado que dejen a la intemperie.

Keyhole is protected by a plastic cover which is a nice touch, helps keep out dirt, snow etc. Lock is hefty...so there is real steel inside the silicon molding. It's a square-ish shaped lock, rather than a U which is actually helpful. Will work great on regular bike tires and most bike frames. Not able to lock through rear wheel of a 4" fat tire ebike though, need to use a cable with the U-Lock. Key turns easily and is well made. Overall the lock and key feel like a great product. I am not concerned with the key breaking off inside the lock, or the lock failing to turn or anything like that. I don't anticipate any issues with this product.

Pretty easy to use and very sturdy, until now working perfectly fine

Overall a decent lock if you live in a safe-ish area, the actual shackle thickness itself is 1/2in thick, the notches on the shackle appear to be cut at an angle for some reason. As for the locking mechanism itself, I highly recommend adding some sort of lube to the lock as it's a little difficult to open/close without it. Now as for security, I'd rate it a 7/10, when my bike is locked up I'm unable to rip the shackle out, drilling the lock looks like it'll do nothing, bolt cutters (folding ones) left a deep-ish mark but after a few minutes I was unable to cut through (did some damage to the bolt cutters). Unfortunately though there are some problems, first off, this can easily be cut off with an angle grinder, and the second problem (which is probably more likely) this can be easily opened with a bump key, with next to ZERO experience using one of these, I was able to open it in less than a minute. Overall I'd still recommend this lock, for the price it appears to perform just like the much more expensive locks, and when combined with a chain or thick super heavy duty steel cable (with its own separate lock), your bike will be FAR less likely to be stolen.

Use este candado para mi motocicleta sujetando la cubierta imperneable, es muy resistente a la lluvia y muuu resistente a impactos, no es indestructible pero si vas a necesitar herramientas muy grandes para cortarlo
