Set-Up
Setting up the Cycplus L7 is straightforward. The device comes with multiple mounting options, including rubber bungee cords and a saddle rail mount, making it compatible with a wide range of bikes. The installation process is simple, and the device pairs quickly with cycling computers and smartphones via Bluetooth or ANT+.
Most people would likely use this bike light on a road bike, and I will likely use it during the summer months, but I am too much of a fair-weather cyclist to cycle outdoors for fun in January.
Instead, I tested this on my Vanpowers City Vanture E-Bike, which I use to commute when it is not raining. Due to the time of year, I often ride in the dark, and the roads can be very busy, so this radar light provides plenty of useful safety features for me.
For most of my testing, I used my Garmin Epix 2 as there is not much need for me to take a bike computer on a 10-mile journey I do each day. However, I also paired and tested it with the Wahoo ELEMNT ROAM V2.
Pairing up with either device was straightforward. With the Garmin, I just went to sensors and accessories and then searched. The L7 shows up as two separate items, one for the light and one for the radar.
The process is basically the same for the Wahoo; just go into the setting and search for sensors.
Performance
Radar Detection
The radar detection system performed reliably during testing. It consistently detected vehicles approaching from behind, providing clear visual and audible alerts on the connected cycling computer. The system’s ability to detect vehicles up to 160 metres away was particularly impressive, giving the rider ample time to react to potential hazards.
On both devices, the radar detection works largely the same. On my Garmin, there is a line that curves around the bezel, which indicates the proximity of a car. When a car is detected, the watch vibrates, and a small dot will show that it moves up the line the closer the car gets. When multiple cars are detected, multiple dots show.
For the Wahoo, the line is on the left, and when a car is detected the LEDs on the top of the computer flash with the line turning red and a small car logo indicating the proximity. Similar to Garmin, multiple cars can be displayed on the line at once.
Tail Light Visibility
The tail light’s 270° visibility proved to be highly effective, especially in low-light conditions. The light’s brightness was sufficient to make the cyclist noticeable to motorists from various angles, reducing the risk of accidents. The accelerometer-based brake light feature, which increases the light’s brightness when the rider slows down, was also a useful addition, providing an extra layer of safety.
Battery Life
The L7’s battery life lived up to expectations, lasting through several long rides without needing a recharge. The device’s ability to operate for up to 36 hours in radar-only mode is a significant advantage, particularly for cyclists who undertake extended rides.
Weather Resistance
The L7’s water-resistant design ensured that it continued to function effectively even in heavy rain. This reliability in adverse weather conditions is a key feature for cyclists who ride year-round, regardless of the weather.
Price and Alternative Options
The Cycplus L7 Radar Tail Light is now available for £79.49 directly from Cycplus.
The Garmin Varia is the original radar tail light and the market leader. The Varia RTL515 has an RRP of £170 but is available on Amazon for £136.
Garmin also has the Varia RCT715, which combines radar, light and a camera. This obviously comes with a premium price tag. The RRP is £350, but it is available for around £285.
The Bryton Gardia R300L is a popular due to its lower price point of £104.
Trek has the Carback Radar Rear Light, which has an RRP for £170 and is available for £113.
The iGPSport SRTL SR30 is available for £120 and is popular due to its 20H battery life.
On Amazon, there is the Magene L508 Bike Radar Tail Light, which is available for £100
Overall
This is my first experience with a radar taillight, so I don’t have any frame of reference against which to compare it, but it has worked as advertised, and I have been happy with the performance.
Clearly, the standout feature of the Cycplus L7 Radar Tail Light is the price point. At the time of writing, it was undercutting popular options by at least 20%.
Overall, I have been really happy with the Cycplus L7, mainly because of the attractive price point as it makes it more appealing to less committed riders like myself. I doubt I would spend £150 on a light like this, as I don’t ride enough to justify it. But a good quality dumb taillight can cost £30, so spending an extra £45 for this is worth it for the increased awareness and safety.
