- Reviewed in Canada on December 21, 2024Verified PurchaseLove this bike alarm for my electric bike. Easy to turn off if bike was bumped in error. I keep the remote control with my bike lock and with me when traveling with our RV and when the bike attached to the back. Gives me peace and mind when stopping over night at a truck stop or RV park for a quick overnight stay when travelling.
Liked it so much , that I ordered second one.
I purchased a bike alarm that goes through the spokes of the bike, it works great , but the alarm is so loud that it hurts your ear while trying to get your key into the lock to turn it off. I like the feature with the remote control, where you can turn it off and not be so close the the loud alarm. Buy this lock… you won’t regret it!

- Reviewed in Canada on November 30, 2024Verified PurchaseIts kinda flimsy. I can see a few spots where this could break quickly. I'm also not a fan of zip ties. Tbh I love zip ties but not when I'm unpacking a new product. How much did you save on production by using zip ties?
Anyhow ths alarm is fairly loud. I still need to select my alarm and volume.
Cheers! Peace!
