Samen voor veiligheid

Een kind dat zelfstandig naar school fietst, voor het eerst alleen naar een vriendje gaat of buiten op avontuur is. Het zijn kleine momenten die voor kinderen heel groot voelen.

Met one2track en Ziemi maken we die momenten net een stukje fijner. Voor kinderen die de wereld willen ontdekken én voor ouders die ze met vertrouwen op pad willen sturen.

Want groot worden doen ze zelf. Wij helpen ze graag een stukje op weg 💙

Frequently asked questions

    Ziemi doesn’t light up the road ahead of you, but rather the cyclist’s moving legs. This makes your Biomotion (your human movement) visible, causing other road users to automatically be more alert and cautious.

    One2track is een GPS horloge. Dat is net als een kleine mobiele telefoon met GPS tracker. Jouw kind kan (video) bellen, spraakberichten en foto’s sturen. Via de one2track ouder app bedien je eenvoudig alle functies van het horloge op afstand en zie je de actuele locatie.

    De horloges zijn bewust gericht op ouder-kindcommunicatie: geen games of social media, zodat kinderen echt buiten kunnen spelen zonder digitale afleiding

Experts on Ziemi

Once I started testing it, I got excited

"At first I was a bit sceptical: the flashy presentation, the trendy box, the slick videos. But once I started testing it, I got excited. I was more visible, visible sooner, and visible from more angles."

Dr. Marcel Aries

Neurologist-intensivist

Being seen better and sooner can make cycling safer

"For ten years now we've seen an alarming rise in the number of cycling casualties in our hospitals. Among cyclists, severe brain injury is the leading cause of death. Being seen better and sooner in traffic is one of the (obvious) interventions that can make cycling safer, fast. This fine Dutch invention is starting to change that."

Gerard Tertoolen

Traffic psychologist

Ziemi is great for car drivers

"You're clearly visible, and drivers see a person instead of a small light. That's a relief for motorists. The benefit is greatest at close range, because that's when you can tell what the other person is about to do. A cyclist can make unexpected movements, and a light like this lets you spot them sooner."

TNO

Scientific Research

Ziemi's lights make you visible over 52% sooner

"Because the light illuminates your moving legs, your biomotion, you're easier to see. TNO research confirms it: Ziemi makes you visible 52% sooner and recognisable as a cyclist 24% sooner."
