Safety First
I ride at night and having a extra level of safety located at your rear is perfect. The automatic shut off and on is a great feature along with the various light options, blink, fast blink, slow heartbeat, steady on and all those mentioned with higher illumination. The mounting brackets were perfect for my MP replica bike, it's not going anywhere by accident.

    The light arrived in its original packaging, in perfect condition. Quality built product, mounting was easy, and has a solid hold (I opted for the saddle mount option) The different modes are great, the smart light feature is on point, works like a charm. It's not as bright as some of the more expensive brands out there, but definitely serves it's purpose. I would highly recommend this product.

    Bought two of these, for two bikes. I can't specify anything I dislike about this product.
    Battery life - great
    Light intencity - great
    Modes - sensical
    Underseat mount - great, rigid, saddle mounted
    Light body is threaded, goes into underseat mount, fine threading holds it tight (I was concerned initially but had no issues with it)
    My only note is: if mounting underseat, pay attention to instructions. There is a couple of plastic inserts coming in the box, they are needed to secure the mount to the saddle, do not disregard them.

    Reviewed in Canada on October 8, 2023
    Verified Purchase
    -GOOD: Unlike some reviews I've read, I didn't have any issue with the rubber attachment, in fact, the light as a whole is of higher than average quality. It has some weight to it, doesn't look and feel cheap, it's very bright and I like how it flashes blue LED's every four seconds indicating battery level. The rubber bracket is elastic and solid rubber and the metal bracket is well designed, both will fit on virtually any bike. Also, the daylight sensor is a great addition that saves battery. The battery lasts fairly long, but that might vary depending on the intensity of use.

    -Personal Inconvenience: This is just my opinion, but having to switch through all the modes to turn off the light is a slightly inconvenient oversight, especially when turning off the light while riding, but one I can live with. I think switching it off by pressing and holding the button for 3 seconds would've been a good feature.

    -ISSUE: I've had this light for a couple of months now, and whilst I truly love everything about this light, and I don't really care clicking multiple times to turn it off, the big problem is actually the selling point. I was indeed skeptical about the brake sensor before buying, mainly the fact that it's likely using an accelerometer or some deceleration sensor, whatever it might be, and that it'll needlessly light up from time to time due to vibrations and when turning, due to the constant changing G forces. I did not expect though that it'll be this bad. It constantly and inconsistently lights up while riding without braking at all, even when accelerating (likely due to motion when pedaling plus vibrations), the whole point of having brake lights is to signal those behind that you're slowing down and they should slow down as well to avoid a collision. You can probably see the issue with having your brake light randomly light up whilst on a road.

    Definitely a solid addition to my road bike. The battery (so far) lasts a really long time, and I like the auto on/off feature which really helps the battery life too. The brake light motion detector seems to work well. Easy to install, would otherwise not know it's there. Brightness I'd say 8/10, you definitely are going to see it in a car or whatever, but I do wish it was a smidge brighter. Has different modes like heart beat or can be left constantly on.

    I also haven't been run over by a car thus far, so I'd definitely would buy again.

    Reviewed in Canada on June 25, 2024

    I was out last night trying my new inertia type brake light to see how effective it was. I first of all turned it on at the third push button spot at night, and it illuminates well. Then I took my scooter down a busy road at night. A police car got behind me as I’m sure that was something new to him. The new red brake light worked well as the police car never lit me up and pulled me over on my scooter.

    Oh and I see the battery works real well too. When I got back home, I see that I still had three blue lights on. So I used little battery power. To recharge the unit, I unscrew the light from the housing attachment and plug the light into a “C” wire battery charger. Yeah, real happy with my new brake light high up on the back seat of my mobility scooter.
