Description

BikeSpark Auto-sensing Rear Light revolutionizes the genre of bike rear lights with Vsenx, an innovative deceleration sensing algorithm (US Patent No.: 10427594 B2) . Vsenx accurately detects braking and riding speed changes, and filters road surface noise and the noise of hard acceleration or standstill. It significantly improves the promptness and correctness of deceleration warning light. BikeSpark perfectly lifts the safety to a new level with deceleration brake warnings for cycling riding. Super bright SMD LEDs providing excellent visibility, up to 20 lm with low power consumption. Deceleration warning when braking detected. BikeSpark’s Auto-Sensing Rear Lights detect bike deceleration with an innovative deceleration sensing algorithm, Vsenx (US Patent No.: 10427594 B2). Once deceleration is detected, BikeSpark increases the brightness to ultra bright for 2.5 seconds, alerting and improving the reaction time of the person in any vehicle traveling behind. Mounting the light couldn’t be easier. There are only 2 steps to attach it on your bike. Step 1. Use the flexible rubber strap to mount securely on your bike. Step 2. Install the BikeSpark Auto-Sensing Rear Light either horizontally or vertically.
