Use Case Ideas: How, Where & Why!
Urban commute after dark: Attach to your seatpost for evening city rides on dry roads; gravity-sensed brake light alerts motorists when you slow at intersections.
Weekend club rides: Use as a rear marker on group road rides, where frequent slowing and regrouping benefit from the automatic brake alert.
Campus cycling between classes: Stay visible on shared paths and parking areas when moving between lectures; the brake light signals to pedestrians and drivers behind you.
Delivery runs in traffic: Mount on your seatpost or rear rack for evening drop-offs; the brake signal helps drivers judge your stops in busy streets.
Early morning training rides: Ride pre-dawn on quiet suburban roads; the gravity sensor brightens on deceleration, warning following cyclists and cars as you approach corners and stop streets.
Installation Guidance, Tips & Tricks
Secure Rear Mounting Position: Place the light on the rear of your bicycle where it is clearly visible and fasten it firmly to prevent movement.
Keep Beam Straight And Clear: Orient the light straight back with no obstructions from bags or clothing to maximize visibility to road users.
Test Gravity Brake Activation: In a safe area, gently slow down and confirm the brake light activates as you decelerate.
Use In Dry Conditions Only: Follow the indoor-use rating and keep the light away from rain, splashes, and high humidity during rides and storage.
Clean Plastic Surface Gently: Wipe the durable plastic housing with a soft, dry cloth to remove dirt and maintain clear visibility.
