# Car-Detecting Bicycle Radars The Garmin Backtracker Helps Cyclists Detect Cars in Their Vicinity By Rahul Kalvapalle | Published 2015-01-19 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/backtracker References: [gizmag](http://www.gizmag.com/garmin-acquires-backtracker-bike-radar/35643/) & [newsroom.garmin](http://newsroom.garmin.com/press-release/fitness/garmin-acquires-assets-ikubu-developer-backtracker-bike-radar) The Backtracker is a [car-detecting bicycle radar system](https://www.trendhunter.com/trends/cyclist-safety1), developed by the now-defunct startup iKubu, that has since been revived by electronics giant [Garmin](https://www.trendhunter.com/trends/rearview-radar-tail-light). This novel system utilizes a pair of high-tech radar modules to detect vehicles around the bicycle, warning the cyclist to exercise caution and ride accordingly. The rear module uses a 24-Gigahertz antenna to scan for vehicles coming up from behind. When it detects a vehicle, it notifies the front module via Bluetooth low energy. This module then alerts the rider to the approach of cars using an LED display. The rear module is also equipped with a [built-in tail light](https://www.trendhunter.com/trends/collision-prevention-system), which blinks more rapidly as vehicles get closer to it. The Backtracker is set to be the first of many iKubu technologies that will be integrated into Garmin products. ## Trend Insights (Trend Hunter) - Score: 5.7/10 - Popularity: 73% | Activity: 91% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### Why This Trend Is Growing - **Bicycle Safety Technology:** The Backtracker is an example of innovative technology that enhances cyclist safety on the road. - **Radar Systems:** Radar technology is being adapted and integrated into new industries, such as cycling safety equipment. - **Bluetooth Low Energy Integration:** The integration of Bluetooth Low Energy technology is becoming more widespread as it improves device communication and energy efficiency. ### Industries Being Reshaped - **Cycling Equipment:** There is an opportunity for the cycling equipment industry to develop and integrate similar radar systems to improve cyclist safety. - **Automotive:** The automotive industry can look for ways to collaborate and integrate safety systems for cyclists to help prevent accidents involving cars and bicycles. - **Electronics:** There is an opportunity for the electronics industry to incorporate Bluetooth Low Energy technology into their devices for more efficient communication and battery life. ## Related on Trend Hunter - [Tech-Enhanced Safety Bike Lights](https://www.trendhunter.com/trends/rear-bike-light.md) - [Connected Cyclist Radar Systems](https://www.trendhunter.com/trends/bryton-gardia-r300l.md) - [Rearview Radar Tail Lights](https://www.trendhunter.com/trends/rearview-radar-tail-light.md) - [Rearview Cyclist Camera Lights](https://www.trendhunter.com/trends/garmin-varia-rct715.md) - [Safety-Focused Motorcycle Radars](https://www.trendhunter.com/trends/motorcycle-radar.md) - [Radar-Equipped Electric Bikes](https://www.trendhunter.com/trends/cannondale-synapse.md) - [Road-Monitoring Cyclist Systems](https://www.trendhunter.com/trends/advanced-driver-assistance-system.md) - [Collision Alert Bike Systems](https://www.trendhunter.com/trends/roadio-system.md) - [Tech-Visible Bike Reflectors](https://www.trendhunter.com/trends/radian-wingman.md)
