ROCKBROS Folding Bike Lock with Mount - Heavy Duty Anti Theft 4-Digit Foldable Lock

I love the solid construction and ease of use. With normal “corkscrew” style bike locks it’s always awkward to unravel it. With this lock it slips out easily and folds up quickly.

The Rock Bros combo Lock is perfect for my 13 year old. She doesn’t have to worry about losing a key and it fits nicely on the bicycle seat tube without any interference while Pedaling. Its compact enough to stay with the bike and use as needed when the bike is unattended like at school. It also appears to be very sturdy and secure.

I've had an Evo lock that is the same set-up as this one, but I misplaced it (found after I purchased this one). It is fairly heavy-duty and is easy enough to get around my front tire and frame. The only reason I knock it down a star is because of how hard it is to move the digits. Getting on one digit dial is difficult, and probably impossible with even liner gloves. Nonetheless, I still like this style due to how easy it is to keep in my pannier.

Really easy for me to pull out and lock up. Be ready that it's a heavy boy, but no heavier than a u lock or chain would be. I like that it folds up nice and tight and goes in and off the bike really quick.

I had liked this lock, however it suddenly stopped working/will not latch and lock properly. Disappointed that it is already not working after only 6 months of use.
