BBB Cycling has launched the Signal Radar rearview radar/tail light. It’s priced competitively, at £119.99, and includes a speaker, so you don’t need a separate device to alert you when a vehicle is detected. It can also be used with a cycling computer or BBB’s app.
BBB claims a detection range of up to 190 metres for the Signal Radar, which it says can simultaneously identify up to eight vehicles.
“It’s our most advanced rear light to date: powerful, smart, and built to protect cyclists in every situation,” says Tjerk Bakker, senior product manager at BBB.
Full range of rearview-radar functionality
As with other rearview radars, the BBB Signal Radar detects an approaching vehicle and includes a tail light that can be programmed to change its lighting and flashing pattern as the vehicle approaches, with the aim of attracting the driver’s attention.
With other radars, you then need another device to alert you as you ride. That’s typically a cycling computer, although you can use some cycling watches, and brands usually have a smartphone app to go with their radars, which you can use as an alert device, if you want to use your phone as a handlebar display.
Like other rearview radars, the Signal Radar can be linked to your chosen head unit using ANT+ or BLE. BBB has co-developed the phone app for its radar with Cannondale, which partnered with Garmin for the SmartSense 2 radar on its Synapse, our 2025 road Bike of the Year.
A first for the BBB Signal Radar is a built-in speaker, so it can be operated without a head unit. It has six lighting modes, with a peak 80-lumen flashing mode its maximum output. BBB says the unit weighs 78g and has a maximum runtime of 14 hours.
Before the BBB Signal Radar, the closest thing to a head-unit-free radar device was the Lezyne Radar Drive, which can be bought in a set with the brand’s React Drive front light. The front light includes red LEDs under a translucent cover at its rear to provide the display function, as well as offering a 1,200-lumen peak output.
The BBB Signal Radar is priced at £119.99 / €139.95 – significantly less than many other radar rear lights, such as the Lezyne Radar Drive and the Garmin RTL515, both priced at £170, and the £180 Wahoo Trackr Radar. Its price is comparable to the MagicShine SeeMe 508 and the Bryton Gardia R300L, both of which need to be used with a head unit, as do the Garmin and Wahoo radars.
