Usually when we report on a luminous cycling product that is crowdfunding on Kickstarter or Indiegogo, it involves some sort of indicator or safety features that extend way beyond just lighting… and while BYB Tech’s new Focus One light promises a ton of smart features and a beam that can pump out a massive 5000 lumen flash, less is more as the unit weighs a mere 49g.
> Find the best bike light for you: the road.cc beam comparison engine 2022
The Italian tech company are making some big claims here, and the device appears to be aimed mostly at road riders; although as shown in the video on the Kickstarter page, we see an electric mountain bike rider connect the light to his e-bike system for unlimited charge.
Lines include “be seen like a car!” and “we believe that bicycles deserve to be more visible on the road.” Whether any amount of lighting or safety features are enough to prevent cyclists suffering the many collisions caused by dangerous motorists each year is another subject entirely; but the aim appears to be to give cyclists the option of deploying a high beam flash to alert potentially distracted drivers of their presence.
BYB Tech says Focus One is the “world’s smallest 5000 lumens bike light” rather than the smallest out there (that would be something like the Bookman Block at a mere 13g) but we’ve not seen anything with this much beam strength in such a small package. The 5000 lumen claim is referring to the Focus One’s ultra high-beam flash mode, that can be triggered by a small button on the unit itself or via the handlebar remote. You can use it up to 500 times on a single charge if you’ve set it to the max power; of course that means there’s an app for the light, which allows you to customise modes and the strength of the beam.
The light can also be used with a steady state beacon constantly flashing for up to 20 hours at a time, and as a regular steady light in ‘low-beam light’ mode. We’re not told exactly how many lumens this kicks out, but on a higher setting BYB Tech says “with the maximum intensity is possible to go for a night ride in the woods too.”
Obviously multiple 5000 lumen flashes at night isn’t going to make you hugely popular with oncoming traffic, but BYB Tech says a tilt sensor accessed via the app can tell you how dazzling or not your beam is going to be, help you find the right angle and “make Focus compliant to StVO rules” [lights that conform to German traffic regulations to avoid dazzling].
BYB Tech’s founder Enrico Rodella also told us: “The light is totally personalizable and you can set the light power from (basically) zero to 5000 lumens (only in high-beam and beacon mode).”
The 49g weight is for the unit itself, not including the mounts or remote trigger. BYB Tech offers a number of mounting options, including a GoPro mount so you can attach it underneath your GPS, and also a quarter-turn option that is “compatible with most existing mounts.” BYB Tech has also shared 3D models of the mounts as open-source files for users to create their own ideal solution.
Other features include the e-bike compatibility and a rear light mode should your main rear light run out. The claimed run time is up to 20 hours on flash and up to six hours in low-beam mode, and recharge time is just 15 minutes.
> Where are they now? 13 of the best, worst and wackiest cycling crowdfunders
This isn’t BYB Tech’s first Kickstarter rodeo, with the brand first taking to the crowdfunding platform for its telemetry system for mountain bikes and motocross. Claimed to be a world first, the system is made up of an accelerometer and gyroscope working with GPS to track the performance of your bike’s components on the go, so you can identify issues and tweak them. It’s tech that pros already had access to, mostly to monitor the performance of their suspension, but BYB Tech packaged this into a product regular consumers could buy too. It’s not cheap at well over £1,000, but the Kickstarter was a success and the product is now on version 2.0.
If the Focus One sounds like the bike light for you, then there are still super earlybird backing options on the Kickstarter to save 50% on the eventual retail price of €249 (~£207). A backing of €125 (~£105) gets you a single Focus One unit, and you can get two for €229 (~£232). The crowdfunder will run until 25th April, with £2,104 pledged of the £16,599 target at the time of writing.
Check out the crowdfunding page here. All the usual Kickstarter rules and regulations apply which can be found here.

It all sounds a little
It all sounds a little dubious, someones not run the numbers correctly. If it takes 15mins for a full charge from micro USB, this must mean that the battery itself is super small. Even 650mah batteries on Lezyne zecto drive lights take about 2hrs+ to charge from flat.
claims to have a dual core CPU — but why would your light need one over a standard battery management circuit/chip?

Hello RoubaixCube,
Hello RoubaixCube,
I’m Enrico the founder of this project.
It’s pretty simple. We’re using high-discharge special batteries (derived from racing drones). They can supply an extremely high peak of current to provide the 5000 lumens beam. In the same way, they can be charged extremely fast without degrading them.
Others bike lights are using standard Lithium batteries which can basically be charged slowly (if you don’t want to kill them).
Cheers
Enrico
If you’re using special
If you’re using special batteries from racing drones chances are they are lipo batteries? These are not meant to be charged unattended as they can be volatile and pose a fire risk. Probably worth considering.

Extremely bright lights are
Extremely bright lights are the cycling version of the 4×4.
A very small number of people actually need them.
Most people have no need for one whatsoever and needlessly make life unpleasant and dangerous for other road users.
I’m sick of being blinded by inconsiderate people on my commute.
Does it not depend on how and
Does it not depend on how and where the beam is focused (and the angle it is fixed to the bike at) ?
I might be getting this
I might be getting this wildly wrong – but surely if you have a 5000 lumen light to be seen, only to have to point it downwards to not blind people, couldn’t you simply have a lower lumen light pointed straight ahead?
In short – isn’t this all a bit pointless?
I think the general idea is,
I think the general idea is, is that you wouldnt be running it at a constant 5000 lumens at all. Only using it for flicking your high beams like when youre behind the wheel of a car and either giving way to another vehicle or saying thank you etc etc.
Most of the time you’ll be using it at the lower power ranges 300-800lumens (though i dont think the battery will actually last as long as they claim)

Saying ‘thank you’?

I’m a cyclist: how DARE you?!!

I’ve never really understoud this – saying “thank you” to another motorist by temporarily blinding them. I find a better option is to blink the lights off (i.e. drop to side lights or daylight running lights).
One change I would like to see made to highway code is to change the advice in rule 115 – there’s no need to have dipped headlights turned on at night to be seen on a lit road. Side lights
or daylight running lightsare more than sufficient. Generally cycle lights only need to be so bright, because they need to compete with the glare motor vehicle headlights (which results in other lights being almost invisible). BTW I like how some motor manufacturers have picked up on the fact that their daylight running lights are brighter than their indicators, and now turn off the light on one side when indicating.*edit daylight running lights probably produce more glare than dipped headlights

The German spec lights I have
The German spec lights I have seen allow a wider and longer arc but are not supposed to dazzle. Useful on nsl roads with no street lights.
I am waiting for the exposure
I am waiting for the exposure stvzo compliant lights to be certified and finally sold.
Big power for off-road downhill, dazzle free lower power to see the road and still be seen. Utility mountain biking perfection. (And gravel…)
My desire for the light will of course decline over the summer and increase again as autumn approaches.
My (admittedly limited)
My (admittedly limited) understanding of stvzo is that a light cannot be certified if it has modes that are not compliant. So to be certified, the light must not have any flashing modes and must not have any “full beam” modes.
There would be nothing to stop Exposure (or other brands) selling a light that has a mode which is compliant with the stvzo regs and also other (non-compliant) modes, but the light as a whole would not be certified.
Lupine make an 1800 lumen
Lupine make an 1800 lumen stvzo compliant (and certified) front light.
Exposure said they were doing quite well on certification but then COVID hit, when I asked when it would finally be available. I kind of wish they would sell the range, along with a certification applied for note. I’d buy one, more road friendly, but with off-road power, better in both ways than my present set up.
For me stvzo would be a nice add on, having a properly legal front light, but for me it would be the tech the light gives.
To some degree you can
To some degree you can mitigate the harm caused by an unnecessarily bright light through careful positioning.
Alternatively you could just select a light (or even a mode) appropriate for what you need!

The only use for a 5000
The only use for a 5000 lumens flash that I can conceive of would be to announce my approach around a blind bend at night, much as would flash my car headlights if I were driving.

Hello @Rich_cs

With Focus you’ll not be blinded anymore.
Focus can’t work steadily at @5000 lumens. You can flick your high-beam in specific situations (for example, a blind turn, a dangerous situation, etc…):
With Focus, people will use the light only if there’s a danger.
Cheers

Hi Enrico, I have good stvzo
Hi Enrico, I have good stvzo lights for constant use and have been looking for an additional main beam light. Can your light be used for a short period as a main beam able to light up the road (particularly at the bottom of a descent where the road rises and I’d like to see above the stvzo beam) as well as just a warning flash?
ChasP wrote:
Hello ChasP,
yes! The light can emit a burst of 5000 lumens just for 5 seconds! Then, the light intensity automatically decreases. The light is very fast to cool down, that’s means you can trigger the high beam more times. (let’s say every 2/3 seconds).
We’re progressing with the campaign, come visit us: https://www.bybtech.it/focus

When power LED’s first came
When power LED’s first came out, I made my own light out of three Lumiled LUXONs bolted to a computer processor heatsink that I cut in half. It looked a bit like this.
Also, if it does any sort of flashing, it’s not StVZO compliant, as flashing is verboten!
Correct, flashing lights are
Correct, flashing lights are not allowed but a recent change to the German law means StVZO-approved lights can include a high-beam mode. In other words, they enable the rider to switch from the StVZO cut-off setting to a more powerful full beam when needed.
Ah, good point!

Hello Prosper,

As explained in the campaign, Focus is not intended to be run hours at 5000 lumens. Focus can emit a burst of light @ 5000 lumens. For example, you can flick your high-beam in specific situations (for example, a blind turn, a dangerous situation, etc…):
More than that, Focus can sustain a low light intensity for more hours.

Hi Enrico, the kickstarter
Hi Enrico, the kickstarter says your light will do 800 lumens for 6+ hours, is that correct, and the chanrging time will be approx 15minutes?
If not could you tell me what time the 800 lumens brghtness will run for? and what brightness it can do for 3 hours?

Hi,
thanks for pointing it out. Thanks to its compact (& drones derived) battery we can provide a super-fast charge. Basically, you can charge your light when you dressing for the ride. 15mins to top-up.
We have a smartphone app that let you choose the exact amount of light you want (there’s a scrollbar from 0 to 100) and the corresponding battery duration is live updated. I can try to attach a screenshot of the app here:
In the current setup, we are able to range the low-beam lifetime from 1/1.5h to 6h+. The intensity ranges from 200 to 800 lumens. You can fine-tune and customize your intensity vs battery duration according to your needs.

Thanks, I need 3-3.5 hours at 500+ lumens so This might not be for me, I’d be interested in a bigger capacity version if you ever do one.
check12 wrote:
Hi check12,
the light intensity to do 3 hours is actually set to 400/450 lumens.
Considering the super-compact it’s a lot. We’re confident of increasing the battery life slightly.
You can always link Focus to an external battery/power bank and selecting the “External battery option” from the smartphone app.
