If it is auto guard, the operation of the smartphone is unnecessary.
If there is an abnormality when you are away from the bike, the alarm sounds, and the notification sound to the smartphone is reliable because it stands out.

If the detection sensitivity is changed, it is safe even if it is parked in the cycle rack.
If you turn off the alarm, you can rest assured at the time of wheel line and transportation.

This is the only device that has GPS and communication capabilities even if you don't receive Bluetooth.

Not only theft, but also mischief can be prevented.

PinareLLO's DOGMA was stolen at Enomoto Ranch in November 2018. It seems to have been cut even if it had the chain lock. The criminal was arrested, but the bike was not able to ride.
After that, I introduced AlterLock, but I felt that i could prevent not only theft but also mischief.
It is important to prevent you from noticing when something happens. It is installed on all bikes that i own.

I'm so glad you're safe!

I parked with a wire lock with a fence in front of a bicycle shop in Tokyo. It took about five minutes away from the bike, but there was a person who was looking at my road bike, so i took the tool out of my pocket and broke the key when I looked away.
However, the alter lock that detected the vibration sounded the alarm, so the culprit ran away.

AlterLock is good to be able to do security without worrying.

If you were looking for a good key on the Internet, you know it's a hot topic, i purchased it. In the past, i was worried about shopping at a convenience store because it was a wire lock.
AlterLock is good to be able to crime without worrying. Things are sure to be! I want it to spread more.
After that, it would be nice if there is a function to share the location information between users.

There is a sense of security when i leave the bicycle.

I got to know the alter lock on the Web and thought it would be useful in the event of a theft deterrent and theft.
Fortunately, I have never been indebted to AlterLock, but I feel secure when I leave my bike. When you leave the bicycle, such as meals, i put the smartphone in the place in view and have to be able to see immediately if there is a notification from AlterLock.
AlterLock also has a theft deterrent effect and tracking function at the time of theft, so i think it's more cost-effective than bike vehicle insurance if you think only of theft.

With the introduction of Alter Rock, we were able to continue to cover the stop-and-drop spots without any consideration.

A new form of anti-theft measures that are different from the key which read the psychology of the thief side. The sound is a threat from the culprit who doesn't want to stand out! It becomes a considerable security measure.

Developed by cyclists, AlterLock is designed specifically for sports bicycles.

Where are you? 」
It becomes familiar with the frame when seeing from the drivetrain side by thinning it to the limit, and it does not notice the existence.
It doesn't get in the way of Insta shine.
The flange flows backwards and considers air resistance.

"Is the battery in this lightness? 」
The amazing lightness should be able to use the racer who is severe in the weight of the motorcycle on a daily basis.
Even so, you can watch the bike for more than a month on a single charge.

Let's go cycling with AlterLock!
