Experts on Ziemi
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."
Eva Rensman

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."
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."
