A fall can happen quickly: rail, leaves, loose ground or carelessness.
RadSirene alerts a friend or wife and shows the position of the fall on the map. Help is quickly at the right place.
Not keeping an eye on your bike during a break - not a good feeling!
RadSirene monitors up to 3 bikes so that you can intervene quickly if necessary.
Theft alarm
Not keeping an eye on your bike during a break - not a good feeling! RadSirene monitors up to 3 bikes so that you can intervene quickly if necessary.
Bicycle crash call
A fall can happen quickly: rail, leaves, loose ground or carelessness. RadSirene alerts a friend or wife and shows the location of the fall on the map. So help is quickly at the right place.
- Tour start: Switch on “Alarm Crash” (crash emergency call on)
- Tour break: Switch on “Alarm Bike” (theft protection for up to 3 bikes)
- End of break: reactivate “Alarm Crash”
Receiving the fall emergency call
The receiver, e.g. boyfriend or wife, has the RadSirene app installed on their cell phone too. When an emergency call is made, a signal sounds cyclically until it is confirmed. Reception and the app are free of charge!
Another very helpful function is “Arrived safely?”. Receive a message when the driver has reached a freely definable destination area.
- For the children's journey to school
- Daughter visits friend
- Son goes to sports
- etc.
Note: The Bike Sensor is not required for this function.
Also for camping: protection for bikes or water sports equipment at night.
App without entering personal data. No account required.
Flexible 24-hour tickets to suit the tour days instead of an annual subscription. App is free of charge.
Suitable for all types of bike: eBike, bicycle, racing bike, cargo bike,...
Crash emergency call + theft alarm + “arrived at destination” message
Theft alarm for up to 3 bikes with just one cell phone!
You get the app for free in the Apple App Store. Receiving messages (Fall / Arrived safely?) is also free of charge! Instead of a yearly subscription, you can book the app for 24-hour tickets. This means that costs are only incurred on tour days!
The Bike Sensor is required for theft protection and fall emergency call. It is mounted on the bike using the bracket supplied on the frame, seat post or handlebars. Other holders are available in the store.
Activate “Alarm Crash” at the start of the tour (fall emergency call). During the tour break, e.g. arrival at the beer garden, activate the “Alarm Bike” (theft protection for up to 3 bikes).
The function monitors up to 3 bikes simultaneously (one bike sensor per bike). If the bikes are tampered with, you will receive an alarm on your cell phone: sound & message including bike name. The “Secured” field shows whether the bike is within range.
RadSirene alerts another cell phone in the event of a crash, e.g. the paired partner cell phone of your boyfriend or wife. Your position is displayed on the map there. So help is quickly at the right place. Receiving the alarm on your partner's cell phone is free of charge.
Another interesting function is “Arrived safely”: Receive a message when your son has arrived at school or your daughter has arrived at her friend's house (arrival in target region). Receiving the message is free of charge.
The partner cell phone is a second cell phone / tablet, where RadSirene is installed too, e.g. from your boyfriend or wife. It receives the “Crash” emergency call and the “Arrived safely?” message via the Internet. The app and notification receiving is free! It is paired simply by scanning a QR code from the biker's cell phone.
For all functions, the cell phone does not need to be mounted on the bike. It remains safe from shocks, sun, etc. ... at the location of your choice. Oh yes, of course RadSirene also works when the display is switched off.
Receive the theft alarm or crash emergency call or the “Arrived safely” message on your Apple Watch too.
