Quick Start Guide

Main functions
1. Automated turn and brake signal
SHIELD by EESENS is the first bike taillight equipped with this “automatic turning signals”
function. Our patented sensor algorithm in the controller detects your gesture of “shoulder
check” correctly by the motion of your head. When your head turns to check the traffic
behind you, the controller on your helmet will check your turning angle, speed and hold
time. If these factors meet the criteria, the controller will trigger the turn light. We have
optimized the ability of the turn-head algorithm over time. Now, the algorithm can detect
FOUR different gestures: look at side, glance backwards, scan backwards and stare
backwards over your shoulder. The later three of them have include most cyclers’ shoulder
checking patterns. You can simply select in the EESENS APP which gestures best fit your
riding habit, to avoid falsely triggering turn signals.
2. Anti-theft alarm
Anti-theft mode of SHIELD will protect your bike. If someone is messing with your bike, a
110-dB alarm will sound to deter bad guys. A warning is also instantly sent to both your
wireless controller on the helmet and the EESENS app.
3. Find-my-bike
After a long day, you may forget the exact location where you parked your bike and feel
frustrated when you search for your bike on the street or in the parking lot. SHIELD can
assist you in searching for your bike efficiently. You can easily turn on “FIND-BIKE” feature
by pressing the wireless sensing controller or virtual button in EESENS APP. A bright light
and loud sound of SHIELD will guide you to your bike’s location.
4. Companion APP
EESENS APP helps you configure the light conveniently, with selections for light mode,
disarm passcode, speed levels of turning head and so on. New software features will be added
to SHIELD through the EESENS APP. Send us your needs. The EESENS team is looking
forward to your feedback, allowing us to upgrade our product to improve your experience.
Risk of using the product
1. The product has passed CE/FCC and reliability test, but it hasn’t been developed completely. It
will have bugs
2. Using VPN is highly recommended because the server is built in US. The local Internet
connection is not reliable.
3. Even the taillight has anti-theft mode. A good bike lock is still needed to prevent from theft.
4. The wireless connection distance between controller and taillight is 130 meters in open space.
The distance will decrease due to blocks or surrounding radiated noise. Next version of
hardware will double the distance.
