Reviews over the

Lezyne Radar React System

Very good product for me, the only downside was the fixing of the radar/rear lights to the seatpost (I have a telescopic saddle). I had to make myself a 3D printed support to fix it to the seat rails.

The build quality is superb, e.g. the aluminium housing of the front light. As a racing cyclist, you immediately think: oha, that's pretty heavy Functions/light modes/luminosity super! App connection/firmware update in seconds. App very functional. Attachment for D-shaped seat posts and aero posts included. Ride report of the lights: A great feeling; contributes more to the feeling of safety than I thought! I rode in the evening sun with the flash at the front and rear and I think I noticed a clear change in the driving behaviour of car drivers. Overtaking drivers overtake more cleanly and carefully, oncoming drivers realise that they have been seen. A BMW SUV driver even let me in front instead of quickly squeezing past the obstacle on his side! I stopped and looked into the light - if you don't actively look into it for a long time, it's definitely not dazzling! At dusk, however, I switched to permanent light. Extremely reliable warning from the radar, no missed alarms, no false alarms. The warning comes much earlier than you even notice the car, especially when the wind is blowing. Even shows how fast a car is approaching and where it is. Also recognises 2 cars in close succession - a source of danger that has often caught me out because I assumed that a car had "passed". The warning and warning tones can be heard very well even in a headwind and are not annoying (perhaps minimally when I was on the cycle path next to a dual carriageway - of course this is also recognised. However, you could also quickly switch off the sound via the app for longer phases like this). The warning light on the front light is also easy to see out of the corner of your eye, so you could generally do without sound. Will definitely always be on the bike now. In summer, possibly only at the rear, even without lights - radar only...
