The Garmin Edge 130 Bike Computer gives cyclists a streamlined, easy to use interface with a slew of sophisticated features for getting faster and pushing farther. The simplified 1. 8-inch display remains easy to read in bright lighting, so you won't be struggling to view key stats, information, or maps when it's sunny outside. Bluetooth Low Energy communicates with most smartphones, Garmin's Cadence and Speed Sensor (sold separately), as well as Bluetooth-compatible power meters, but without draining your battery prematurely. GPS, GLONASS, and Galileo tracking quickly lock onto satellites, allowing you to find your location and start tracking your ride the minute you step outside and begin pedaling. GPS tracking provides an accurate assessment of distance and duration, with the ability to pair it with Garmin's Speed and Cadence sensor for additional cycling stats. Turn-by-turn navigation means you won't have to worry about getting lost on a far-flung ride into the hills above town or when you're in the middle of a large city that's completely new to you. Smart notifications from your phone allow you to stay in touch while you're cycling far from home or view an incoming message you've been waiting for. Also, you can use the LiveTrack feature, which lets family and friends view your real-time location as you ride. If you do happen to have something go wrong on the road or trail, there's even an assistance feature that'll send your current location to chosen contacts (requires a compatible smartphone with Bluetooth). Additionally, the Edge 130 works with Garmin's Varia lights and rearview radar, so it'll give you alerts of approaching traffic and better help drivers see you on the road.
