Advanced Anti Theft Protection for Your Motorcycle

This motorcycle disc lock alarm provides a reliable way to help deter tampering and unauthorized movement. Its motion detection system automatically activates when vibration or motion is detected, offering an added layer of security when parked or stored.

Easy One Touch Activation

Simply attach the lock to your brake disc and press to arm. An audible signal confirms activation, and the system automatically engages after five seconds for quick and convenient setup.

Powerful Motion Sensing Alarm

Equipped with a sensitive motion detector, the built-in 120dB siren triggers immediately if movement or vibration is detected. This loud alert draws attention and discourages theft attempts in any environment.

Durable and Weatherproof Build

The lock body is constructed from hardened aluminum alloy designed to resist cutting, corrosion, and impact. With an IP67 water-resistance rating, it functions reliably in rain and wet conditions, making it suitable for outdoor or all-season use.

Long Battery Life and Convenient Charging

A single USB-C charge supports up to six months of standby time. The rechargeable lithium battery provides lasting power without frequent replacements, keeping the system ready for regular use.

Didn't have to follow up

Got the confirmation right away, then another email when it shipped. Tracking worked and the package arrived when they said it would. Pretty straightforward

Better price than other places

Shopped around a little before ordering and this was quite a bit cheaper. Delivery went as expected too, so I'm happy with it.

Actually answered my question

I emailed before ordering because I couldn't figure out which option I needed. Got a real explanation of the differences, not just a link to the page I'd already read. Sounds like a small thing, but it helped me decide. Ordered that evening and I'm happy with what showed up.

Good experience again

My first order was just something small a few months ago. That went well, so I checked here when I needed something else. A completely different kind of purchase this time, but ordering was just as easy. Saved me another evening of shopping around!

Picked the wrong option

Totally my mistake, I chose the wrong option and didn't notice until I got the confirmation. Sent an email and they were able to change it before it shipped. Glad I didn't have to deal with sending it back afterward!

Wasn't sure at first

Hadn't heard of Embermont before and wasn't sure about ordering from somewhere new. Just bought one thing to start. It took a little while to ship, but they kept me updated and everything arrived as described. Happy with the purchase and I'd feel comfortable ordering again.

Helpful when there was a problem

There was a mix-up with my order, so I reached out. Sent a photo and they explained what would happen next. Didn't have to tell the same story to a bunch of different people, which I appreciated. All taken care of now

Found it online instead

They didn't have the one I wanted when I stopped by the store, but suggested checking online. Was able to order it on the website later that day. Would've preferred to take it home right then, but this worked out fine.

Return was straightforward

The order arrived fine, but I decided not to keep it. Emailed about a return and got clear instructions. I was mostly worried about having to follow up on the refund, but got a confirmation once the return was processed and the money came back afterward. Didn't have to chase it down.

Exchange taken care of

Needed to exchange my order for a different option and figured it would be a hassle. It didn't happen overnight, but the team explained what to do and kept me updated. The replacement is here now and it's the right one this time. Thanks for helping me sort it out.

Thanks, Michael!

Michael, the owner, was patient with all my questions when I stopped by the store. I hadn't quite decided what I wanted and didn't feel pushed to buy anything. Went home, thought it over and ordered online later.

Helpful even after the purchase

Had a question after my order arrived and wasn't sure how much help I'd get once the sale was done. They got back to me with a clear answer and that took care of it. Happy with the purchase, but the help afterward stood out.
