Frequently asked questions

What’s the difference compared to standard bike lights?

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.

Can I turn a standard bike light round as well?

With standard bicycle lights, it is important that the light has a wide beam angle to ensure a clear view of the road ahead. If such a bicycle light were to be turned upside down, this would not only dazzle you, but it would also obstruct the view of other road users. Ziemi has been carefully designed to illuminate only the cyclist’s moving legs.

Is the Ziemi a replacement for your traditional headlight?

No, the Ziemi is not intended as a replacement for your traditional front light. It remains important to use a standard front light to ensure you can see the road clearly and are visible from the front.

Ziemi is a supplementary light that makes your moving legs visible from the front and sides, making you more recognisable as a cyclist and safer in traffic.

The Biomotion Rear Light has a two-in-one function. It acts both as a traditional rear light and as a light that illuminates your legs.

Aren't reflectors enough for side visibility?

Reflectors definitely improve visibility and are compulsory on every bicycle. However, reflectors work reactively. This means that light must first hit them before they become visible. Consider a situation at a roundabout: if you’re approaching from the corner of someone’s eye, the light hits the reflector too late.

The Ziemi ensures that you are constantly visible and well-lit whilst taking part in traffic. It is precisely in the corner of the eye that you now stand out, thanks to a larger illuminated surface area and your recognisability as a person.

Won’t vehicles approaching from behind think that the cyclist is cycling the wrong way round, because the white light is shining towards the rear?

The Ziemi housing is designed in such a way that the light is directed exclusively at the cyclist’s moving legs and is then reflected towards the front and sides. As a result, the white light is only visible from the front and sides, and not from behind.

Doesn't the Ziemi work blindingly? Doesn't the light shine in your eyes?

The Ziemi is designed to shine only on your legs and nowhere else. When you’re on your bike, you won’t notice it in your field of vision, so you can set off with peace of mind.

Can I recharge the Ziemi? Or does this have batteries?

The Ziemi has a built-in rechargeable battery. You will receive a matching usb-c cable included in each package. As a result the Ziemi can last for years and can be used every time.
