I saw one of these last week and just assumed it was tied into the brake lights but it was always on.

Oh, now I see that it's just based on an accelerometer. Marketing it as "wireless" seems to suggest that it is monitoring the brake lights rather than "automatically" flashing based on motion.

Tbf, even cars put the brake lights on based purely on deceleration nowadays in addition to triggering when the brake pedal is pressed. It's covered by legislation in both EU and US, since BEVS and PHEVs can have very aggressive regen braking, and the legislation basically says if your rate of deceleration is above X, then lights need to be on even if the brake pedal hasn't been pressed.

I actually think it is lame when engine braking activates the brake light. There are two distinct behaviors: slowing down gently, with engine braking, and slowing down intensely with physical brake application. When I am engine braking like going down a long hill I do not want to flag the drivers behind me that I am braking ... I just want to use the compression of the engine to regulate my speed. Anyone who lives in…

Agree and currently it's a dealbreaker to me, however I'm certain it will become optional in the future iterations.

When I was commuting daily in the SF fog, I discovered that putting on of these [1] on my helmet did wonders to keep cars further off my tail. It moves the brake light up to eye level for people in SUVs and also triggers on engine braking. Wish it were cheaper, but was a worthwhile investment for me. Also, consider looking into airbag vests if you ride regularly. Also expensive but (supposedly) make a huge difference…

I helped Alex invent that product! I built the first prototype that helped him get funding and hand assembled some of the first PCB designs. My (old) name is on the patent. I’m glad to see this was already posted. I wear mine when I ride my 1500w ebike around and I feel so much safer with it. It’s really bright too!

That's cool. What principles is it based on and was it difficult to clean up the signals to get a reliable input?

If you read the article then you will see that the accelerometer is a feature that makes it safer. Apparently, motorcycles can brake even if you don't use the brake, and then you really want the lights to turn on.

With BLE integration and an app showing you great deals on bulbs.

And also ads for unrelated products down at the bottom of the page in the app.

ads are amateur hour - gotta make it a subscription and really milk those users.

You'd only see it on newer bikes with ABS, they seem likely to have more sensors and "electronics" in the brake system. In that kind of system the deceleration could be inferred from existing speed signals. I wouldn't be surprised if ABS systems already estimate the engine braking torque directly.

What is the general consensus on ABS braking in motorcycles? Really curious to hear from anyone who has rode a bike equipped with it. For some reason the idea of a bike interfering with brake controls seems like it could feel unsafe if the system isn't designed really well. Extremely low margin for error when it comes to braking on a 2 wheel vehicle especially in suboptimal conditions. I could see ABS braking being f…

There's no such thing as "consensus" in any hobby, but the general trends are:

1. ABS on motorbikes has been proven to prevent lock-ups and therefore accidents, especially among newer riders who are more likely to grab all the brakes in situations where modulation of brake application is required to prevent an accident.

2. Traditionalists say that ABS keeps new riders from having to learn to correctly modulate the brakes and thus keeps them reliant on ABS forever, and that experienced riders can stop quicker without ABS. (The last point is technically true but it requires a highly-skilled rider and a certain set of conditions.)

ABS is bikes IS typically designed very well. (Although I have to take the Internet's word for it since my bike is a 1979 GS850G.)

Another problem is that on most bycicles right leaver is the REAR brake, while on motoryclces it FRONT. It make difference when braking in turns. I was actually considering swapping my bike brakes left to right but it turns out one of the cables is too short. :(

US bicycles, that is. In the UK the bicycle brakes are the other way around.

The UK and Us drive on different sides of the roads and are taught to user different arms for signals as a result. If I'm going to turn I need to both slow down by using the brakes and signal to others. thus I want the rear brakes (even thought front can stop faster I don't want to risk losing traction on that wheel in traffic)

Front brake is where it's most beneficial as the front wheel is what keeps the bike upright. If you lock the front wheel, especially in a turn, the bike falls over almost instantly. edit: Rear wheel locking gives a bit more time to react. Personally the main safety benefit is for emergency braking in wet conditions. ABS also allows to use full brakes in the wet without worrying so much about falling over. That's the…

> ABS also allows to use full brakes in the wet without worrying so much about falling over. That's the real benefit, real-world it shortens your stopping distance because of that increased confidence in using the brake. I think this point is worth emphasizing. You'll hear from a lot of folks on motorcycle forums that ABS will increase stopping distance. Which is true for great drivers performing threshold braking. H…

I'd consider myself a pretty good rider but I've caught myself once or twice jamming on the brakes when a chaotic accident unfolds in front of me and the lizard brain takes over. I live in LA so lots of traffic and lots of accidents are common and any technology that helps my lizard brain keep me alive in a positive in my book.

I recently crashed cornering during a light mist and now I'm on the looking for anything that helps lean slippage. I know you can't fix stupid but still hoping something is out there. My old and busted vstrom needs an upgrade.
