E-Lett

E-Lett is a fast, modern companion app for the Cortina E-Lett e-bike. It connects over Bluetooth and puts everything you need on one screen, before and during your ride. YOUR BIKE, AT A GLANCE • Live battery, estimated range, speed and motor current • Light on or off with one tap • Your bike reconnects automatically when you come back in range • Last-known battery and range, even when the bike is switched off RIDE YOUR WAY • Switch between Speed, Eco, Normal and Torque modes • Set assist from 0 to 5, or tap Boost for full power • Every change is read back from the bike, so what you see is what you get ON YOUR WRIST • See speed, battery and range on your Apple Watch • Turn the Digital Crown to change assist, without reaching for your phone • Switch the light and riding mode from your wrist The watch app works through your iPhone, which stays connected to the bike. COCKPIT FOR YOUR HANDLEBAR Mount your iPhone on the handlebar and open the cockpit: huge speed, battery, range, riding time and distance on a black screen, with turn-by-turn directions while you navigate. EVERY RIDE, LOGGED • Trips start and end on their own when your bike connects and disconnects • Route on a map, distance, riding time, average and max speed • Battery used, Wh/km, energy, climbing and an estimate of calories burned • Export any ride as GPX • Routes are recorded with your phone in your pocket, and stay on your iPhone BRING ME HOME Running low and still a way to go? Enter the distance (or let the app measure the ride home) and E-Lett manages motor power for the whole trip, retuning it every kilometer so assist doesn't cut out before you arrive. ROUTES THAT FIT YOUR BATTERY • Search a destination or drop a pin to get cycling routes with alternatives • Each route is checked against your real range • Simple turn-by-turn guidance while you ride • One-tap routes home or to work BEAT THE RAIN • Rain radar on the map, from an hour ago to two hours ahead • Save your commute and work schedule, and E-Lett checks the rain along your route before every ride • Get an alert when leaving a bit earlier or later keeps you dry RANGE THAT LEARNS FROM YOU The range estimate is based on how much battery you used over your last 10 km, so it reflects your riding, your route and your assist level.
