Tight U-shaped lock is unnecessary

First of all, the item image that comes with the product is the first product image. Image 2 and 3 are attached to the seat post, but there are no metal fittings for installation. I attached it directly to the V brake, but it was not necessary to attach it to the seat post and it was fixed enough. You can use one hand to remove the key, but you must use both hands when locking. I tried to force it with force and the key was bent. be careful. Locking / unlocking will be easy to do if you get used to it, so it will be freed from the trouble of winding out the chain and carrying the heavy lock.

Sorry for lack of grease.

It's sturdy and I feel a bit hard. Installation is also in a flash. Since there is only a key at the time of unlocking, it is very good without being hanging at the time of driving.

I installed it on a road bike for commuting.

I attached it to the road bike through the mounting screw of the caliper brake in the hole on the upper side. In the fixing method, the upper hole was tightened together with the caliper brake and the metallic hose band was fixed to the seat stay in the vertically elongated hole on the right and left. When tightening together with the caliper brake, care must be taken so that the lock will not be distorted due to the step difference between the seat stay and the seat stay bridge, for example by pinching the washer on the frame side. After installation, the movement of the lock did a good shopping well.

Attached to the cross bike of the caliper brake

After checking the size of the official website product specification, it was longer than the brake arch length, I thought that I could attach it if I devised it. Body size: External size / width about 14 × height about 17 cm, inside dimension / width of about 4.5 × height of about 12 cm Body weight: about 570 g (excluding accessories) Since the bolt of the caliper brake enters the hole in the center We fixed using left and right, with spacer of plastic attached and insulock. Locking without a key was possible when the body bowed a little. It was quicker locked than wire lock, making it convenient.

The product was a good one, but ...

First of all, the attached cap bolt for fixing, it did not become usable because it crooked. I bought it and installed it at home center if similar screws come with returned goods. I attached the SK11 folding bike of Doppel Ganger. It did not have extra stay, but it felt refreshed ... but because it can not be mounted in parallel with the spoke, we could not lock it unless we spared the spokes while avoiding the spokes (lol). A more miserable situation occurred. SK11, the stand is next to the pedal, but depending on the position of the pedal, the pedal will catch on the stand and the tire can not be rotated. Then you will not be able to unlock the lock (cry) To take it off, take the stand or remove the chain, you have to pedal free

Easy locking possible

Purchased conveniently and conveniently when you want to stop a little bit for a bit of shopping. Mount is mountain bike. It also becomes a V brake booster, and it looks smart when attached. Although lock can be done without key, we needed to push in quite strongly and we could not go on snowy with one hand. It is necessary to take out the key one by one, but it is smoother to lock it by inserting the key. To be able to lock even if there is no key means that if you forget to leave the key and you are locked by mischief you will not be able to move (laugh) When you ride a bicycle, you should have a key or a finger pointer check Right. At the time of running, the silver locking rod stops facing downwards. The lock mechanism is attached so as not to hit the spoke accidentally by vibration. There is weight feeling. But if you think about carrying a U-shaped lock, it will be lightly done.
