Tour of
the Flasher
Bicycle Turn Signal Set
Drive distraction-free.
Focus on traffic.
The "Vibration Navigation" is a free feature of the Flasher armbands, which you can control via the free Flasher app.
How the Bicycle Navigation System Works
1. Enter route
Plan your route in the free Flasher app, komoot (NEW), Google Maps or Apple Maps and start navigation.
2. Put your phone away
From now on, you won't need a screen or headphones to distract you. Just plug in your phone and keep your eyes on the road.
3. Navigate using vibrations in the wristbands
When you have to turn, the left or right wristband vibrates – once a short distance before the turn and twice directly when you need to turn. The vibration motors are so strong that you can feel the signals even through a thick jacket.
FAQ
How do I turn the bike indicator on and off?
To turn the turn signal on and off, simply swing your elbow quickly upwards without letting go of the handlebars. This way, both hands can remain on the handlebars throughout the entire ride.
Do the bracelets also hold on bare skin or when I sweat?
Yes, the armbands will stay on your bare upper arm – even when you sweat. Thanks to the non-slip silicone, they remain securely on your arm. For optimal comfort, it's best to wear them close to your elbow.
How much does navigation by vibration cost?
Vibration navigation is free, no matter which navigation service you use. To use it, you need the free Flasher app. You can find this in the App Store and on Google Play.
Map data from the following providers can be used for navigation:
- komoot (NEW!)
- Google Maps, or
- Apple Maps

Do drivers pay attention to brake lights and turn signals on a cyclist?
We use the same signals as all other vehicles on the road (yellow as turn signal, red as brake light, red/white as front and rear light) so that you can blend in equally with road traffic. Flashing lights also attract more attention than static lights. A particular advantage is that the lights, similar to those on cars, are mounted at your outermost points. This makes the turn signal particularly clear and unambiguous.
Is your bike indicator StVO-compliant and approved for road traffic?
Yes, the Flasher turn signal complies with the StVO (Road Traffic Regulations) and is approved for road use.
§ 9 para 3 StVO requires a clear and timely indication of the change in direction, whereby you can choose the method of indication yourself.
Do the turn signal wristbands work without an app?
Yes, the Flasher bracelets can also be used without the Flasher app.
The turn signal, brake light and lighting (night, jogging and emergency) can be used on the bike at any time without the app.
The settings of the bracelets can be adjusted via the free app (turn up brightness, make turn signal more sensitive, etc.). The app is also needed to enter the destination when using the "navigation by vibration" function.
