Affordable security
These wheel locks are awesome. They take up no room on bike and I feel safer with my bike parked outside on out of town trips.

Not bad. But there is probably better around the same price..
Works as it should. Comes with batteries installed and an extra set. The case is worthless tho.

Stops thieves!
I've had two electric scooters stolen despite being locked, so I thought I'd turn things up a notch by locking the brake. This lock is perfect for that because it's not nearly as easy as cutting through a regular chain or even U-lock, at least not without ruining the disc brake. What I didn't expect was for the alarm to be so effective! It's very loud and seems to let out an initial warning chirp if the scooter gets jostled. If it gets jostled again, it goes into full alarm mode. No, it won't stop determined thieves or organized bike/scooter theft rings, but I've gone some time now without another theft, and I would like to thank this lock for that. I imagine it must make casual thieves second guess whether they should waste their time considering the loud noise and not being able to make a quick getaway. By the way, in case you own a Gotrax GXL V2, that's the scooter I have and the lock does fit the disc brake. However, you might have to rotate the brake a bit by hand to find a hole for the lock to fit through. Not quite as easy as with a bike, but it's workable.

Fantastic!
Great lock for the price. I purchased it for my Ninja 500 and it fits perfectly on the brake rotor without any issues. The lock feels solid and well-made, and the alarm is much louder than I expected. One of the things I was most concerned about was whether I would actually hear the alarm if someone tampered with the bike. I live on the third floor of an apartment building, and I can easily hear it from my apartment. That alone gives me a lot more peace of mind when the bike is parked outside. Setup was simple, the fit was perfect, and the alarm is definitely attention-grabbing. Highly recommend for anyone looking for an extra layer of security for their motorcycle.

Very good
Here's a brief, natural review for a motorcycle lock: ⭐⭐⭐⭐⭐ Excellent safety and quality I bought this lock for my motorcycle and it has exceeded my expectations. It feels very sturdy, with good quality materials and a solid locking mechanism. It is easy to put on and take off, but at the same time it conveys a lot of confidence when I leave the bike parked. In addition, its size is practical to transport without being uncomfortable. After several weeks of use, it continues to function perfectly and with no signs of wear. I recommend it to any motorcyclist looking for a safe and durable option to protect their vehicle.

Zayıf Ürün
Ocak ayında aldım. Pili kendi kendine hemen bitti. Yanında yedek pil yoktu. Piline bakmak için içini açtığımda çok azda olsa yağmur aldığını gördüm.
