I don't know how good it is for safety, I wanted it more for the handbrake on my scooter on inclined roads and it does the job perfectly fine

Finally, a serious and proper handlebar at a normal price. Personally, I use it on an electric scooter and no other handlebar I bought (some cheap plastic ones for 8 euros) did the job. It is made of metal, sturdy construction, and locks perfectly without fully pressing the brake (which implies fluid/wear on the brake pads and discs). As a plus, I will mention that it does not require a key to lock. You simply push the latch downwards and it locks securely. To unlock, of course, you use the key, turn it, and the latch goes up and unlocks. In the package, there are also some plastic pieces that you can stick on the lock if your grip is thinner and it brings it to the ideal thickness. I needed the grip for the scooter as it fit perfectly on the factory lock diameter. In terms of security, don't expect miracles, it will simply delay the potential thief or deter random thieves who won't bother if the vehicle has a few extra things, they will go for the next easier target.

Quite heavy. I believe it is quite useful in delaying possible theft. Value for money (Purchased with shipping costs €16.50)!

Quite good and sturdy construction. I have bought 2. One for the front brake and one for locking the gear lever. You can find it much cheaper abroad, around 15€. It is quite heavy. It is not the most reliable because it is CNC, but it delays a thief quite a bit. I mainly use it as a "handbrake" on uphill slopes because the engine locks if you have it on the front brake.
