Garmin's Varia bike radars are some of the most popular pieces of cycling tech around – and now the company has delivered its first rearview radar to have been specially designed for some of the best e-Bikes . Garmin's Varia range mounts to the back of your bike and broadcasts a radar signal behind you, so you can get visual and audible alerts when something's overtaking you. Even better, the new Varia eRTL615 plugs directly into most e-bikes, with no battery required. Because the catchily-named Varia eRTL615 is also a tail light, it'll also make sure you're visible to other vehicles too, promising to emit a flashing or solid light that's visible from up to a mile away in daylight. To connect Garmin's new radar tail light to your e-bike, you'll need to pick the right Garmin adapter cable (which isn't included). You can buy power cables compatible with Bosch, Shimano, or USB-A terminals or connections, with more info on those available on Garmin...
